The opinion of the Court was delivered by
POLLOCK, J.
This is an appeal from an order of the Appellate Division granting summary judgment to plaintiff, Georgia O’Keeffe, against defendant, Barry Snyder, d/b/a Princeton Gallery of Fine Art, for replevin of three small pictures painted by O’Keeffe. O’Keeffe v. Snyder, 170 N.J.Super. 75 (1979). In her complaint, filed in March, 1976, O’Keeffe alleged she was the owner of the paintings and that they were stolen from a New York art gallery in 1946. Snyder asserted he was a purchaser for value of the paintings, he had title by adverse possession, and O’Keeffe’s action was barred by the expiration of the six-year period of limitations provided by N.J.S.A. 2A:14-1 pertaining to an action in replevin. Snyder impleaded third party defendant, Ulrich A. Frank, from whom Snyder purchased the paintings in 1975 for $35,000.
The trial court granted summary judgment for Snyder on the ground that O’Keeffe’s action was barred because it was not commenced within six years of the alleged theft. The Appellate Division reversed and entered judgment for O’Keeffe. O'Keeffe, supra, 170 N.J.Super. at 92. A majority of that court concluded that the paintings were stolen, the defenses of expiration of the statute of limitations and title by adverse possession were identical, and Snyder had not proved the elements of adverse possession. Consequently, the majority ruled that [484]*484O’Keeffe could still enforce her right to possession of the paintings.
The dissenting judge stated that the appropriate measurement of the period of limitation was not by analogy to adverse possession, but by application of the “discovery rule” pertaining to some statutes of limitation. He concluded that the six-year period of limitations commenced when O’Keeffe knew or should have known who unlawfully possessed the paintings, and that the matter should be remanded to determine if and when that event had occurred. Id. at 96-97.
We granted certification to consider not only the issues raised in the dissenting opinion, but all other issues. 81 N.J. 406 (1979). We reverse and remand the matter for a plenary hearing in accordance with this opinion.
I
The record, limited to pleadings, affidavits, answers to interrogatories, and depositions, is fraught with factual conflict. Apart from the creation of the paintings by O’Keeffe and their discovery in Snyder’s gallery in 1976, the parties agree on little else.
O’Keeffe contended the paintings were stolen in 1946 from a gallery, An American Place. The gallery was operated by her late husband, the famous photographer Alfred Stieglitz.
An American Place was a cooperative undertaking of O’Keeffe and some other American artists identified by her as Marin, Hardin, Dove, Andema, and Stevens. In 1946, Stieglitz arranged an exhibit which included an O’Keeffe painting, identified as Cliffs. According to O’Keeffe, one day in March, 1946, she and Stieglitz discovered Cliffs was missing from the wall of the exhibit. O’Keeffe estimates the value of the painting at the time of the alleged theft to have been about $150.
About two weeks later, O’Keeffe noticed that two other paintings, Seaweed and Fragments, were missing from a storage room at An American Place. She did not tell anyone, even Stieglitz, about the missing paintings, since she did not want to upset him.
[485]*485Before the date when O’Keeffe discovered the disappearance of Seaweed, she had already sold it (apparently for a string of amber beads) to a Mrs. Weiner, now deceased. Following the grant of the motion for summary judgment by the trial court in favor of Snyder, O’Keeffe submitted a release from the legatees of Mrs. Weiner purportedly assigning to O’Keeffe their interest in the sale.
O’Keeffe testified on depositions that at about the same time as the disappearance of her paintings, 12 or 13 miniature paintings by Marin also were stolen from An American Place. According to O’Keeffe, a man named Estrick took the Marin paintings and “maybe a few other things.” Estrick distributed the Marin paintings to members of the theater world who, when confronted by Stieglitz, returned them. However, neither Stieglitz nor O’Keeffe confronted Estrick with the loss of any of the O’Keeffe paintings.
There was no evidence of a break and entry at An American Place on the dates when O’Keeffe discovered the disappearance of her paintings. Neither Stieglitz nor O’Keeffe reported them missing to the New York Police Department or any other law enforcement agency. Apparently the paintings were uninsured, and O’Keeffe did not seek reimbursement from an insurance company. Similarly, neither O’Keeffe nor stieglitz advertised the loss of the paintings in Art News or any other publication. Nonetheless, they discussed it with associates in the art world and later O’Keeffe mentioned the loss to the director of the Art Institute of Chicago, but she did not ask him to do anything because “it wouldn’t have been my way.” O’Keeffe does not contend that Frank or Snyder had actual knowledge of the alleged theft.
Stieglitz died in the summer of 1946, and O’Keeffe explains she did not pursue her efforts to locate the paintings because she was settling his estate. In 1947, she retained the services of Doris Bry to help settle the estate. Bry urged O’Keeffe to report the loss of the paintings, but O’Keeffe declined because “they never got anything back by reporting it.” Finally, in 1972, O’Keeffe authorized Bry to report the theft to the Art [486]*486Dealers Association of America, Inc., which maintains for its members a registry of stolen paintings. The record does not indicate whether such a registry existed at the time the paintings disappeared.
In September, 1975, O’Keeffe learned that the paintings were in the Andrew Crispo Gallery in New York on consignment from Bernard Danenberg Galleries. On February 11, 1976, O’Keeffe discovered that Ulrich A. Frank had sold the paintings to Barry Snyder, d/b/a Princeton Gallery of Fine Art. She demanded their return and, following Snyder’s refusal, instituted this action for replevin.
Frank traces his possession of the paintings to his father, Dr. Frank, who died in 1968. He claims there is a family relationship by marriage between his family and the Stieglitz family, a contention that O’Keeffe disputes. Frank does not know how his father acquired the paintings, but he recalls seeing them in his father’s apartment in New Hampshire as early as 1941-1943, a period that precedes the alleged theft. Consequently, Frank’s factual contentions are inconsistent with O’Keeffe’s allegation of theft. Until 1965, Dr. Frank occasionally lent the paintings to Ulrich Frank. In 1965, Dr. and Mrs. Frank formally gave the paintings to Ulrich Frank, who kept them in his residences in Yardley, Pennsylvania and Princeton, New Jersey. In 1968, he exhibited anonymously Cliffs and Fragments in a one day art show in the Jewish Community Center in Trenton. All of these events precede O’Keeffe’s listing of the paintings as stolen with the Art Dealers Association of America, Inc. in 1972.
Frank claims continuous possession of the paintings through his father for over thirty years and admits selling the paintings to Snyder. Snyder and Frank do not trace their provenance, or history of possession of the paintings, back to O’Keeffe.
As indicated, Snyder moved for summary judgment on the theory that O’Keeffe’s action was barred by the statute of limitations and title had vested in Frank by adverse possession. For purposes of his motion, Snyder conceded that the paintings had been stolen. On her cross motion, O’Keeffe urged that the [487]*487paintings were stolen, the statute of limitations had not run, and title to the paintings remained in her.
II
In general, cross motions for summary judgment do not “obviate a plenary trial of disputed issues of fact, where such exists; nor do cross-motions constitute a waiver by the litigants to such a trial.” Rotwein et al. v. General Accident Group & Cas. Co., 103 N.J.Super. 406, 424-425 (Law Div.1968). Cross motions do not warrant granting summary judgment unless one of the moving parties is entitled to judgment as a matter of law. 6 Moore’s Federal Practice (2d ed. 1976), § 56.13 at 341. Cross motions for summary judgment do not preclude the existence of issues of fact. Id. at 345. Although a defendant may assert that, according to his theory of the case, the material facts are undisputed, he must be allowed to show that if plaintiff’s theory is adopted there remains a genuine issue of material fact. See Walling v. Richmond Screw Anchor Co., 154 F.2d 780, 784 (2d Cir. 1946), cert. den. 328 U.S. 870, 66 S.Ct. 1383, 90 L.Ed. 1640 (1946). Where there are cross motions for summary judgment, a party may make concessions for the purposes of his motion that do not carry over and support the motion of his adversary. 6 Moore’s, supra, § 56.13 at 344. Eagle v. Louisiana and Southern Life Insurance Company, 464 F.2d 607, 608 (10th Cir. 1972); Begnaud v. White, 170 F.2d 323, 327 (6th Cir. 1948).
The Appellate Division accepted O’Keeffe’s contention that the paintings had been stolen. However, in his deposition, Ulrich Frank traces possession of the paintings to his father in the early 1940’s, a date that precedes the alleged theft by several years. The factual dispute about the loss of the paintings by O’Keeffe and their acquisition by Frank, as well as the other subsequently described factual issues, warrant a remand for a plenary hearing. See Judson v. Peoples Bank & Trust Co. of Westfield, 17 N.J. 67 (1954).
In reversing the cross motions for summary judgment, the Appellate Division erred in accepting one of two conflicting versions of material fact: the theft of the paintings in March, [488]*4881946 as asserted by O’Keeffe as against the possession of the paintings by the Frank family since the early 1940’s. Instead of recognizing the existence of this controversy, the Appellate Division misconstrued Snyder’s concession that the paintings had been stolen. That concession was made to enable the trial court to determine Snyder’s motion for summary judgment that title had passed by adverse possession. The concession was not available to resolve O’Keeffe’s cross motion for summary judgment. Hence, there is an issue of material fact, whether the paintings were stolen, that compels remand for trial.
Without purporting to limit the scope of the trial, other factual issues include whether (1) O’Keeffe acquired title to Seaweed by obtaining releases from the legatees of Mrs. Weiner; (2) the paintings were not stolen but sold, lent, consigned, or given by Stieglitz to Dr. Frank or someone else without O’Keeffe’s knowledge before he died; and (3) there was any business or family relationship between Stieglitz and Dr. Frank so that the original possession of the paintings by the Frank family may have been under claim of right.
Ill
On the limited record before us, we cannot determine now who has title to the paintings. That determination will depend on the evidence adduced at trial. Nonetheless, we believe it may aid the trial court and the parties to resolve questions of law that may become relevant at trial.
Our decision begins with the principle that, generally speaking, if the paintings were stolen, the thief acquired no title and could not transfer good title to others regardless of their good faith and ignorance of the theft. Joseph v. Lesnevich, 56 N.J.Super. 340, 346 (App.Div.1959); Kutner Buick, Inc. v. Strelecki, 111 N.J.Super. 89, 97 (Ch.Div.1970); see Ashton v. Allen, 70 N.J.L. 117, 119 (Sup.Ct.1903). Proof of theft would advance O’Keeffe’s right to possession of the paintings absent other considerations such as expiration of the statute of limitations.
[489]*489Another issue that may become relevant at trial is whether Frank or his father acquired a “voidable title” to the paintings under N.J.S.A. 12A:2-403(1). That section, part of the Uniform Commercial Code (U.C.C.), does not change the basic principle that a mere possessor cannot transfer good title. 2 Anderson, Uniform Commercial Code (2d ed. 1971) § 2-403:6 at 41 (Anderson). Nonetheless, the U.C.C. permits a person with voidable title to transfer good title to a good faith purchaser for value in certain circumstances. N.J.S.A. 12A:2-403(1). If the facts developed at trial merit application of that section, then Frank may have transferred good title to Snyder, thereby providing a defense to O’Keeffe’s action. No party on this appeal has urged factual or legal contentions concerning the applicability of the U.C.C. Consequently, a more complete discussion of the U.C.C. would be premature, particularly in light of our decision to remand the matter for trial.
On this appeal, the critical legal question is when O’Keeffe’s cause of action accrued. The fulcrum on which the outcome turns is the statute of limitations in N.J.S.A. 2A:14-1, which provides that an action for replevin of goods or chattels must be commenced within six years after the accrual of the cause of action.
The trial court found that O’Keeffe’s cause of action accrued on the date of the alleged theft, March, 1946, and concluded that her action was barred. The Appellate Division found that an action might have accrued more than six years before the date of suit if possession by the defendant or his predecessors satisfied the elements of adverse possession. As indicated, the Appellate Division concluded that Snyder had not established those elements and that the O’Keeffe action was not barred by the statute of limitations.
Since the alleged theft occurred in New York, a preliminary question is whether the statute of limitations of New York or New Jersey applies. The New York statute, N.Y. Civ. Prac. Law § 214 (McKinney), has been interpreted so that the statute of limitations on a cause of action for replevin does not begin to run until after refusal upon demand for the return of the goods. [490]*490Menzel v. List, 49 Misc.2d 300, 267 N.Y.S.2d 804 (Sup.Ct.1966), aff’d as modified, 28 A.D.2d 516, 279 N.Y.S.2d 608 (App.Div. 1966), third party claim reversed on other grounds, 24 N.Y.2d 91, 246 N.E.2d 742, 298 N.Y.S.2d 979 (Ct.App.1969). Here, O’Keeffe demanded return of the paintings in February, 1976. If the New York statute applied, her action would have been commenced within the period of limitations.
The traditional rule to determine which of two statutes of limitations is applicable is that the statute of the forum governs unless the limitation is a condition of the cause of action. See Marshall v. Geo. M. Brewster & Son, Inc., 37 N.J. 176 (1962). However, this Court has discarded the mechanical rule that the statute of limitations of the forum must be employed in every suit on a foreign cause of action. Heavner v. Uniroyal, Inc., 63 N.J. 130, 140-141 (1973). Heavner set out five requirements for barring an action by applying a statute of limitations other than the appropriate New Jersey statute: (1) the cause of action arose in the other state; (2) the parties are all present in and amenable to jurisdiction in the other state; (3) New Jersey has no substantial interest in the matter; (4) the substantive law of the other jurisdiction is applicable, and (5) the limitations’ period of the other jurisdiction has expired at the time of the commencement of the suit in New Jersey. Id. at 141. The Heavner rule provides a limited and special exception to the general rule that the rule of the forum determines the applicable period of limitations. Raskulinecz v. Raskulinecz, 141 N.J.Super. 148, 153 (Law Div.1976). In the present case, none of the parties resides in New York and the paintings are located in New Jersey. On the facts before us, it would appear that the appropriate statute of limitations is the law of the forum, N.J.S.A. 2A:14-1. On remand, the trial court may reconsider this issue if the parties present other relevant facts.
IV
On the assumption that New Jersey law will apply, we shall consider significant questions raised about the interpretation of N.J.S.A. 2A:14-1. The purpose of a statute of limita[491]*491tions is to “stimulate to activity and punish negligence” and “promote repose by giving security and stability to human affairs”. Wood v. Carpenter, 101 U.S. 135, 139, 25 L.Ed. 807, 808 (1879); Tevis v. Tevis, 79 N.J. 422,430-431 (1979); Fernandi v. Strully, 35 N.J. 434, 438 (1961). A statute of limitations achieves those purposes by barring a cause of action after the statutory period. In certain instances, this Court has ruled that the literal language of a statute of limitations should yield to other considerations. Compare, e. g., Velmohos v. Maren Engineering Corp., 83 N.J. 282, 293 (1980) with Galligan v. Westfield Centre Service, Inc., 82 N.J. 188, 192-193 (1980).
To avoid harsh results from the mechanical application of the statute, the courts have developed a concept known as the discovery rule. Lopez v. Swyer, 62 N.J. 267, 273-275 (1973); Prosser, The Law of Torts (4 ed. 1971), § 30 at 144-145; 51 Am.Jur.2d, Limitation of Actions, § 146 at 716. The discovery rule provides that, in an appropriate case, a cause of action will not accrue until the injured party discovers, or by exercise of reasonable diligence and intelligence should have discovered, facts which form the basis of a cause of action. Burd v. New Jersey Telephone Company, 76 N.J. 284, 291-292 (1978). The rule is essentially a principle of equity, the purpose of which is to mitigate unjust results that otherwise might flow from strict adherence to a rule of law. Lopez, supra, 62 N.J. at 273-274.
This Court first announced the discovery rule in Fernandi, supra, 35 N.J. at 434. In Fernandi, a wing nut was left in a patient’s abdomen following surgery and was not discovered for three years. Id. at 450-451. The majority held that fairness and justice mandated that the statute of limitations should not have commenced running until the plaintiff knew or had reason to know of the presence of the foreign object in her body. The discovery rule has since been extended to other areas of medical malpractice. See, e. g., Lopez, supra (alleged negligent radiation therapy following a radical mastectomy for breast cancer); Yerzy v. Levine, 108 N.J.Super. 222 (App.Div.), aff’d per curiam as modified, 57 N.J. 234 (1970) (negligent severance by surgeon of bile duct).
[492]*492Increasing acceptance of the principle of the discovery rule has extended the doctrine to contexts unrelated to medical malpractice. See, e. g., Diamond v. New Jersey Bell Telephone Co., 51 N.J. 594, 596-597 (1968) (discovery rule applicable in negligent installation of an underground conduit causing flooding of plaintiff’s property); New Mkt. Poultry Farms, Inc. v. Fellows, 51 N.J. 419, 425 (1968) (discovery rule applicable to negligently prepared survey discovered eleven years after the act); Brown v. College of Medicine and Dentistry, 167 N.J.Super. 532, 536-537 (Law Div.1979) (dicta would permit action for lost wages pursuant to breach of union’s duty to represent fairly bargaining unit even though action instituted beyond period of limitations); McCoy Co., Inc. v. S.S. “Theomitor III”, 133 N.J. Super. 308 (Law Div.1975) (discovery rule permits untimely amendment of complaint to include subsidiary corporations where parent company had been sued within limitations’ period); Gibbins v. Kosuga, 121 N.J.Super. 252 (Law Div.1972) (cause of action allowed under N.J.S.A. 2A:14-1 when plaintiffs discovered nine years after closing that well was not located on their property). See also Rosenau v. City of New Brunswick, 51 N.J. 130, 139-140 (1968) (discovery rule discussed as applying to cause of action under N.J.S.A. 2A:14-1 for damage to plaintiff's home fourteen years after installation of defective water meter).
The statute of limitations before us, N.J.S.A. 2A:14-1, has been held subject to the discovery rule in an action for wrongful detention of shares of stock. Federal Insurance Co. v. Hausler, 108 N.J.Super: 421, 426 (App.Div.1970). In Hausler, the defendant purchased preferred stock of a corporation through a stockbroker. On March 9, 1961, the broker erroneously sent to the customer a certificate for common stock of greater value. The broker discovered the error in December, 1961, but did not learn the identity of the customer’s account in which the error was made until November, 1962. Defendants refused to exchange the common stock for the preferred stock. Plaintiff, a bonding company subrogated to the broker’s rights, instituted an action on July 2,1968, within six years of the date on which the broker learned the identity of the defendants as the customers who [493]*493wrongfully received the common stock, but more than six years after the broker knew it had a cause of action. Judge Goldmann, writing for a unanimous court, reversed the grant of a summary judgment for defendants and remanded the matter for a full trial to determine whether (1) the broker knew or reasonably should have known of the error and the defendants’ identity in December, 1961 and (2) defendants knew of the mistake from the beginning and fraudulently concealed it. Overruling the trial court which had concluded “[t]his is not a good case in which to apply the discovery rule”, Judge Goldmann found the discovery rule applicable. Id. at 424, 426.
Similarly, we conclude that the discovery rule applies to an action for replevin of a painting under N.J.S.A. 2A:14-1. O’Keeffe’s cause of action accrued when she first knew, or reasonably should have known through the exercise of due diligence, of the cause of action, including the identity of the possessor of the paintings. See N. Ward, Adverse Possession of Loaned or Stolen Objects—Is Possession Still Vioths of the Law?, published in Legal Problems of Museum Administration (ALI-ABA 1980) at 89-90.
We leave to the discretion of the trial judge whether to conduct a preliminary hearing to determine whether O’Keeffe is entitled to the benefit of the discovery rule. Ordinarily that determination would be made in a preliminary hearing out of the presence of the jury. Lopez, supra, 62 N.J. at 275. But if much of the evidence adduced at the hearing will be the same as that adduced at trial, the judge may elect to receive the evidence in the course of the trial and decide the limitations question at the end of the plaintiff’s case or at the conclusion of all evidence. If that procedure is adopted, the trial judge should exclude the jury when the anticipated evidence relates only to the limitations issue, as receipt of that evidence in the presence of the jury might prejudice another party. Id. at 275 n. 3.
In determining whether O’Keeffe is entitled to the benefit of the discovery rule, the trial court should consider, among others, the following issues: (1) whether O’Keeffe used [494]*494due diligence to recover the paintings at the time of the alleged theft and thereafter; (2) whether at the time of the alleged theft there was an effective method, other than talking to her colleagues, for O’Keeffe to alert the art world; and (3) whether registering paintings with the Art Dealers Association of America, Inc. or any other organization would put a reasonably prudent purchaser of art on constructive notice that someone other than the possessor was the true owner.
V
The acquisition of title to real and personal property by adverse possession is based on the expiration of a statute of limitations. R. Brown, The Law of Personal Property (3d ed. 1975), § 4.1 at 33 (Brown). Adverse possession does not create title by prescription apart from the statute of limitations. Walsh, Title by Adverse Possession, 17 N.Y.U.L.Q.Rev. 44, 82 (1939) (Walsh); see Developments in the Law—Statutes of Limitations, 63 Harv.L.Rev. 1177 (1950) (Developments).
To establish title by adverse possession to chattels, the rule of law has been that the possession must be hostile, actual, visible, exclusive, and continuous. Redmond v. New Jersey Historical Society, 132 N.J.Eq. 464, 474 (E. & A.1942); 54 C.J.S. Limitations of Actions § 119 at 23. Redmond involved a portrait of Captain James Lawrence by Gilbert Stuart, which was bequeathed by its owner to her son with a provision that if he should die leaving no descendants, it should go to the New Jersey Historical Society. The owner died in 1887, when her son was 14, and her executors delivered the painting to the Historical Society. The painting remained in the possession of the Historical Society for over 50 years, until 1938, when the son died and his children, the legatees under his will, demanded its return. The Historical Society refused, and the legatees instituted a replevin action.
The Historical Society argued that the applicable statute of limitations, the predecessor of N.J.S.A. 2A:14-1, had run and that plaintiffs’ action was barred. The Court of Errors and Appeals held that the doctrine of adverse possession applied to [495]*495chattels as well as to real property, Redmond, supra, 132 N.J.Eq. at 473, and that the statute of limitations would not begin to run against the true owner until possession became adverse. Id. at 475. The Court found that the Historical Society had done nothing inconsistent with the theory that the painting was a “voluntary bailment or gratuitous loan” and had “utterly failed to prove that its possession of the portrait was ‘adversary’, ‘hostile’.” Id. at 474-475. The Court found further that the Historical Society had not asserted ownership until 1938, when it refused to deliver the painting to plaintiff, and that the statute did not begin to run until that date. Consequently, the Court ordered the painting to be returned to plaintiffs.
The only other New Jersey case applying adverse possession to chattels is Joseph v. Lesnevich, 56 N.J.Super. 340 (App.Div. 1949). In Lesnevich, several negotiable bearer bonds were stolen from plaintiff in 1951. In October, 1951, Lesnevich received an envelope containing the bonds. On October 21, 1951, Lesnevich and his business partner pledged the bonds with a credit company. They failed to pay the loan secured by the bonds and requested the credit company to sell the bonds to pay the loan. On August 1, 1952, the president of the credit company purchased the bonds and sold them to his son. In 1958, within one day of the expiration of six years from the date of the purchase, the owner of the bonds sued the credit company and its president, among others, for conversion of the bonds. The Appellate Division found that the credit company and its president held the bonds “as openly and notoriously as the nature of the property would permit”. Lesnevich, supra, 56 N.J.Super. at 355. The pledge of the bonds with the credit company was considered to be open possession.
As Lesnevich demonstrates, there is an inherent problem with many kinds of personal property that will raise questions whether their possession has been open, visible, and notorious. In Lesnevich, the court strained to conclude that in holding bonds as collateral, a credit company satisfied the requirement of open, visible, and notorious possession.
[496]*496Other problems with the requirement of visible, open, and notorious possession readily come to mind. For example, if jewelry is stolen from a municipality in one county in New Jersey, it is unlikely that the owner would learn that someone is openly wearing that jewelry in another county or even in the same municipality. Open and visible possession of personal property, such as jewelry, may not be sufficient to put the original owner on actual or constructive notice of the identity of the possessor.
The problem is even more acute with works of art. Like many kinds of personal property, works of art are readily moved and easily concealed. O’Keeffe argues that nothing short of public display should be sufficient to alert the true owner and start the statute running. Although there is merit in that contention from the perspective of the original owner, the effect is to impose a heavy burden on the purchasers of paintings who wish to enjoy the paintings in the privacy of their homes.
In the present case, the trial court and Appellate Division concluded that the paintings, which allegedly had been kept in the private residences of the Frank family, had not been held visibly, openly, and notoriously. Notwithstanding that conclusion, the trial court ruled that the statute of limitations began to run at the time of the theft and had expired before the commencement of suit. The Appellate Division determined it was bound by the rules in Redmond and reversed the trial court on the theory that the defenses of adverse possession and expiration of the statute of limitations were identical. Nonetheless, for different reasons, the majority and dissenting judges in the Appellate Division acknowledged deficiencies in identifying the statute of limitations with adverse possession. The majority stated that, as a practical matter, requiring compliance with adverse possession would preclude barring stale claims and acquiring title to personal property. O’Keeffe, supra, 170 N.J. Super, at 86. The dissenting judge feared that identifying the statutes of limitations with adverse possession would lead to a “handbook for larceny”. Id. at 96. The divergent conclusions of the lower courts suggest that the doctrine of adverse possession [497]*497no longer provides a fair and reasonable means of resolving this kind of dispute.
The problem is serious. According to an affidavit submitted in this matter by the president of the International Foundation for Art Research, there has been an “explosion in art thefts" and there is a “worldwide phenomenon of art theft which has reached epidemic proportions”.
The limited record before us provides a brief glimpse into the arcane world of sales of art, where paintings worth vast sums of money sometimes are bought without inquiry about their provenance. There does not appear to be a reasonably available method for an owner of art to record the ownership or theft of paintings. Similarly, there are no reasonable means readily available to a purchaser to ascertain the provenance of a painting. It may be time for the art world to establish a means by which a good faith purchaser may reasonably obtain the provenance of a painting. An efficient registry of original works of art might better serve the interests of artists, owners of art, and bona fide purchasers than the law of adverse possession with all of its uncertainties. L. DuBoff, The Deskbook of Art Law at 470-472 (Fed.Pub.Inc.1977). Although we cannot mandate the initiation of a registration system, we can develop a rule for the commencement and running of the statute of limitations that is more responsive to the needs of the art world than the doctrine of adverse possession.
We are persuaded that the introduction of equitable considerations through the discovery rule provides a more satisfactory response than the doctrine of adverse possession. The discovery rule shifts the emphasis from the conduct of the possessor to the conduct of the owner. The focus of the inquiry will no longer be whether the possessor has met the tests of adverse possession, but whether the owner has acted with due diligence in pursuing his or her personal property.
For example, under the discovery rule, if an artist diligently seeks the recovery of a lost or stolen painting, but cannot find it or discover the identity of the possessor, the statute of limita[498]*498tions will not begin to run. The rule permits an artist who uses reasonable efforts to report, investigate, and recover a painting to preserve the rights of title and possession.
Properly interpreted, the discovery rule becomes a vehicle for transporting equitable considerations into the statute of limitations for replevin, N.J.S.A. 2A:14-1. In determining whether the discovery rule should apply, a court should identify, evaluate, and weigh the equitable claims of all parties. Lopez, supra, 62 N.J. at 274. If a chattel is concealed from the true owner, fairness compels tolling the statute during the period of concealment. See Lopez, supra, 62 N.J. at 275 n. 2; Developments, supra, 1220 (1950). That conclusion is consistent with tolling the statute of limitations in a medical malpractice action where the physician is guilty of fraudulent concealment. See Tortorello v. Reinfeld, 6 N.J. 58, 67 (1950); Bauer v. Bowen, 63 N.J.Super. 225 (App.Div.1960).
It is consistent also with the law of replevin as it has developed apart from the discovery rule. In an action for replevin, the period of limitations ordinarily will run against the owner of lost or stolen property from the time of the wrongful taking, absent fraud or concealment. Where the chattel is fraudulently concealed, the general rule is that the statute is tolled. 51 Am. Jur.2d, Limitation of Actions, § 124 at 693; 54 C.J.S. Limitations of Actions, § 119 at 23; Annotation, “When statute of limitations commences to run against action to recover, or for conversion of, property stolen or otherwise wrongfully taken,” 136 A.L.R. 658, 661-665 (1942); see Dawson, Fraudulent Concealment and Statutes of Limitation, 31 Mich.L.Rev. 875 (1933); Annotation, “What constitutes concealment which will prevent running of statutes of limitations,” 173 A.L.R. 576 (1948); Annotation, “When statute of limitations begins to run against action for conversion of property by theft,” 79 A.L.R.3d 847, § 3 at 853 (1975); see also Dawson, Estoppel and Statutes of Limitation, 34 Mich.L.Rev. 1, 23-24 (1935).
A purchaser from a private party would be well-advised to inquire whether a work of art has been reported as lost or [499]*499stolen. However, a bona fide purchaser who purchases in the ordinary course of business a painting entrusted to an art dealer should be able to acquire good title against the true owner. Under the U.C.C. entrusting possession of goods to a merchant who deals in that kind of goods gives the merchant the power to transfer all the rights of the entruster to a buyer in the ordinary course of business. N.J.S.A. 12A:2-403(2). In a transaction under that statute, a merchant may vest good title in the buyer as against the original owner. See Anderson, supra, § 2-403:17 et seq. The interplay between the statute of limitations as modified by the discovery rule and the U.C.C. should encourage good faith purchases from legitimate art dealers and discourage trafficking in stolen art without frustrating an artist’s ability to recover stolen art works.
The discovery rule will fulfill the purposes of a statute of limitations and accord greater protection to the innocent owner of personal property whose goods are lost or stolen. Accordingly, we overrule Redmond v. New Jersey Historical Society, supra, and Joseph v. Lesnevich, supra, to the extent that they hold that the doctrine of adverse possession applies to chattels.
By diligently pursuing their goods, owners may prevent the statute of limitations from running. The meaning of due diligence will vary with the facts of each case, including the nature and value of the personal property. For example, with respect to jewelry of moderate value, it may be sufficient if the owner reports the theft to the police. With respect to art work of greater value, it may be reasonable to expect an owner to do more. In practice, our ruling should contribute to more careful practices concerning the purchase of art.
The considerations are different with real estate, and there is no reason to disturb the application of the doctrine of adverse possession to real estate. Real estate is fixed and cannot be moved or concealed. The owner of real property knows or should know where his property is located and reasonably can be expected to be aware of open, notorious, visible, hostile, continuous acts of possession on it.
[500]*500Our ruling not only changes the requirements for acquiring title to personal property after an alleged unlawful taking, but also shifts the burden of proof at trial. Under the doctrine of adverse possession, the burden is on the possessor to prove the elements of adverse possession. Wilomay Holding Co. v. Peninsula Land Co., 36 N.J.Super. 440, 443 (App.Div.1955), certif. den. 19 N.J. 618 (1955). Under the discovery rule, the burden is on the owner as the one seeking the benefit of the rule to establish facts that would justify deferring the beginning of the period of limitations. See Lopez, supra, 62 N.J. at 276.
VI
Read literally, the effect of the expiration of the statute of limitations under N.J.S.A. 2A:14-1 is to bar an action such as replevin. The statute does not speak of divesting the original owner of title. By its terms the statute cuts off the remedy, but not the right of title. Nonetheless, the effect of the expiration of the statute of limitations, albeit on the theory of adverse possession, has been not only to bar an action for possession, but also to vest title in the possessor. There is no reason to change that result although the discovery rule has replaced adverse possession. History, reason, and common sense support the conclusion that the expiration of the statute of limitations bars the remedy to recover possession and also vests title in the possessor.
Professor Brown explains the historical reason for construing the statute of limitations as barring the right of title as well as an action for possession:
The metamorphosis of statutes simply limiting the time in which an action may be commenced into instrumentalities for the transfer of title may be explained perhaps by the historical doctrine of disseisin which, though more customarily applied to land, was probably originally controlling as to chattels also. By this doctrine the wrongful possessor as long as his possession continued, was treated as the owner and the dispossessed occupant considered merely to have a personal right to recapture his property if he could. [Brown, supra, § 4.1 at 34]
See 3 Am.Jur.2d, Adverse Possession, § 202 at 290-292; 3 American Law of Property, § 15.16 at 834.
[501]*501Before the expiration of the statute, the possessor has both the chattel and the right to keep it except as against the true owner. The only imperfection in the possessor’s right to retain the chattel is the original owner’s right to repossess it. Once that imperfection is removed, the possessor should have good title for all purposes. Ames, The Disseisin of Chattels, 3 Harv. L.Rev. 313, 321 (1890) (Ames). As Dean Ames wrote: “An immortal right to bring an eternally prohibited action is a metaphysical subtlety that the present writer cannot pretend to understand.” Id. at 319.
Recognizing a metaphysical notion of title in the owner would be of little benefit to him or her and would create potential problems for the possessor and third parties. The expiration of the six-year period of N.J.S.A. 2A:14-1 should vest title as effectively under the discovery rule as under the doctrine of adverse possession.
Our construction of N.J.S.A. 2A:14-1 is consistent with the construction of N.J.S.A. 2A:14-6, one of the statutes pertaining to title by adverse possession of real estate. That statute recites that one with right or title of entry into real estate shall make such entry within 20 years after the accrual of the right or be barred. It does not expressly state that the expiration of 20 years vests title in the possessor. Two other statutes pertaining to the adverse possession of real estate, N.J.S.A. 2A:14-30 and 31, expressly state that adverse possession for the statutory period shall vest title in the possessor. Notwithstanding the difference in wording between N.J.S.A. 2A:14-6 and N.J.S.A 2A:14-30 and 31, the former statute has always been construed as vesting title in the adverse possessor at the end of the statutory period. See, e. g., Braue v. Fleck, 23 N.J. 1, 16 (1956).
To summarize, the operative fact that divests the original owner of title to either personal or real property is the expiration of the period of limitations. In the past, adverse possession has described the nature of the conduct that will vest title of a chattel at the end of the statutory period. Our adoption of the discovery rule does not change the conclusion that at the end of the statutory period title will vest in the possessor.
[502]*502VII
We next consider the effect of transfers of a chattel from one possessor to another during the period of limitation under the discovery rule. Under the discovery rule, the statute of limitations on an action for replevin begins to run when the owner knows or reasonably should know of his cause of action and the identity of the possessor of the chattel. Subsequent transfers of the chattel are part of the continuous dispossession of the chattel from the original owner. The important point is not that there has been a substitution of possessors, but that there has been a continuous dispossession of the former owner.
Professor Ballantine explains:
Where the same claim of title has been consistently asserted for the statutory period by persons in privity with each other, there is the same reason to quiet and establish the title as where one person has held. The same flag has been kept flying for the whole period. It is the same ouster and disseisin. If the statute runs, it quiets a title which has been consistently asserted and exercised as against the true owner, and the possession of the prior holder justly enures to the benefit of the last. [H. Ballantine, Title by Adverse Possession, 32 Harv.L. Rev. 135, 158 (1919)]
The same principle appears in the Restatement (Second) of Torts:
In some cases, the statute of limitations begins to run before the defendant took possession as when a previous taker converted the chattel and later transferred possession to the defendant. [Restatement (Second) of Torts 2d § 899 at 442 (1977)]
For the purpose of evaluating the due diligence of an owner, the dispossession of his chattel is a continuum not susceptible to separation into distinct acts. Nonetheless, subsequent transfers of the chattel may affect the degree of difficulty encountered by a diligent owner seeking to recover his goods. To that extent, subsequent transfers and their potential for frustrating diligence are relevant in applying the discovery rule. An owner who diligently seeks his chattel should be entitled to the benefit of the discovery rule although it may have passed through many hands. Conversely an owner who sleeps on his rights may be denied the benefit of the discovery rule although the chattel may have been possessed by only one person.
[503]*503We reject the alternative of treating subsequent transfers of a chattel as separate acts of conversion that would start the statute of limitations running anew. At common law, apart from the statute of limitations, a subsequent transfer of a converted chattel was considered to be a separate act of conversion. In his dissent, Justice Handler seeks to extend the rule so that it would apply even if the period of limitations had expired before the subsequent transfer. Nonetheless, the dissent does not cite any authority that supports the position that the statute of limitations should run anew on an act of conversion already barred by the statute of limitations. Adoption of that alternative would tend to undermine the purpose of the statute in quieting titles and protecting against stale claims. Brown, supra, § 4.3 at 38.
The majority and better view is to permit tacking, the accumulation of consecutive periods of possession by parties in privity with each other. Lesnevich, supra, 56 N.J.Super. at 357; see also O’Connell v. Chicago Park Dist, 376 Ill. 550, 34 N.E.2d 836 (1941); Brown, supra, § 18-39; Walsh, supra at 84; Comment, 14 RukL.Rev. 443, 444-445 (1960).
As explained by Professor Walsh:
The doctrine of tacking applies as in corresponding cases of successive adverse possessions of land where privity exists between such possessors. Uncertainty is created by cases which hold that each successive purchaser is subject to a new cause of action against which the statute begins to run from that time, in this way indefinitely extending the time when the title will be quieted by operation of the statute. It should be entirely clear that the purposes of statutes of limitation are the same whether they relate to land or chattels, and therefore the same reasons exist for tacking successive possessions as the prevailing cases hold. Nevertheless, under the cases, new actions in conversion arise against successive purchases of the converted property, and there is strong reason back of the argument that the statute runs anew against each succeeding cause of action. No doubt the prevailing rule recognizing privity in these cases may be based upon the argument that the possessory title is transferred on each successive sale of the converted chattel, subject to the owner’s action to recover the property, and the action of replevin which is his proprietory action, continues in effect against succeeding possessors so that the statute bars the action after the successive possessions amount to the statutory period. [Walsh, supra at 83-84]
In New Jersey tacking is firmly embedded in the law of real property. O’Brien v. Bilow, 121 N.J.L. 576, 578-579 (E. & A.1938). The rule has been applied also to personal property. [504]*504Lesnevich, supra, 56 N.J.Super. at 357. In Lesnevich, the pledge of the bonds with the credit company and the subsequent purchase by the company’s president were separate acts of conversion. The pledge was beyond the period of the statute of limitations and the purchase was within the period. Id. at 353. The Appellate Division permitted tacking of the two periods, with the result that the second act of conversion did not alter the running of the period. Id. at 357.
The dissent by our colleague Justice Handler seeks to distinguish Lesnevich because it involved negotiable instruments. However, the law of negotiable instruments was irrelevant to the decision since the court held the credit company and its president were not holders in due course. Lesnevich, supra, 56 N.J.Super. at 352.
Treating subsequent transfers as separate acts of conversion could lead to absurd results. As explained by Dean Ames:
The decisions in the case of chattels are few. As a matter of principle, it is submitted this rule of tacking is as applicable to chattels as to land. A denial of the right to tack would, furthermore, lead to this result. If a converter were to sell the chattel, five years after its conversion, to one ignorant of the seller’s tort, the disposed owner’s right to recover the chattel from the purchaser would continue five years longer than his right to recover from the converter would have lasted if there had been no sale. In other words, an innocent purchaser from a wrong-doer would be in a worse position than the wrong-doer himself,—a conclusion as shocking in point of justice as it would be anomalous in law. [Ames, supra at 323, footnotes omitted]
It is more sensible to recognize that on expiration of the period of limitations, title passes from the former owner by operation of the statute. Needless uncertainty would result from starting the statute running anew merely because of a subsequent transfer. 3 American Law of Property, § 15.16 at 837. It is not necessary to strain equitable principles, as suggested by the dissent, to arrive at a just and reasonable determination of the rights of the parties. The discovery rule permits an equitable accommodation of the rights of the parties without establishing a rule of law fraught with uncertainty.

We recognize the possible relevancy of claims of common law and statutory copyright and related questions of in[505]*505fringement. The parties have not raised any copyright issue in the pleadings, on the motion for summary judgment, or on this appeal. On the limited record before us, we cannot evaluate the existence or merit of copyright claims. Depending on the evidence adduced at trial, copyright claims may arise under federal statutes or the common law. For present purposes, it is sufficient to note that there are valuable rights in a work of art, apart from the right to title and possession; such as, the rights of reproduction, distribution, and display. Those rights, assembled under the rubric of a copyright, are not involved in this appeal.
Shortly before and after oral argument, various motions were filed with the Court. A motion by O’Keeffe for acceleration is now moot. Motions to supplement the record by O’Keeffe and Snyder, as well as a petition by the Art Dealers Association of America to file a brief amicus curiae, raise essentially factual matters. Because we remand this matter for trial, those motions also are rendered moot.
O’Keeffe is a distinguished American artist, now 92 years old and living in New Mexico. In this proceeding, she has been deposed in her attorney’s office in New York City. At oral argument, we were informed that she had visited New York recently for reasons unrelated to the litigation. Nonetheless, if, because of her age, O’Keeffe is unable to travel to New Jersey for trial, an appropriate application may be made to the trial court to perpetuate her testimony. Furthermore, we direct the trial court to expedite both discovery proceedings and the trial.
We reverse the judgment of the Appellate Division in favor of O’Keeffe and remand the matter for trial in accordance with this opinion.
