ROBERT M. BELL, Judge.
The propriety of a trial court’s order, entered at the mother’s behest, that the man who acknowledges paternity of a child born out of wedlock take a blood test to establish that paternity, is one of the issues presented in this case. The related issue, whether the results of the blood test properly were admitted into evidence and deemed to be dispositive of the acknowledged father’s custody claim, is also presented. Holding that it was reversible error to require the acknowledged father to submit to a blood test, the Court of Special Appeals reversed the judgment of the Circuit Court for Baltimore County, which had upheld a master in chancery’s admission of blood test results, excluding the acknowledged father as the biological father, into evidence and, on the basis of that evidence, transferred custody of the child from the acknowledged father to her mother. Monroe v. Monroe, 88 Md.App. 132, 594 A.2d 577 (1991). We granted the petition for certiorari filed by Patricia Thomas Monroe, the petitioner, in order that we might consider the important issues this case presents.
I.
After they had been dating for a short time, the petitioner informed Donald P. Monroe, the respondent, that she was pregnant with his child. Skeptical, due to his having a low sperm count, the respondent requested that the petitioner take a “voice stress analysis test,” which she did. The results of the test “proved” that the petitioner believed that the respondent was the father of the expected baby. Thereafter, when the baby, Beth, was born, the respondent was present in the delivery room and his name was placed on the [761]*761birth certificate as the father. After about two and a half years, during which the parties and Beth lived together, the parties were married.
Within months after the marriage, following an argument, the petitioner told the respondent that he was not Beth’s father. They separated. When the petitioner filed a complaint for absolute divorce, the respondent, answering it, filed a Motion For Order Requiring Blood Tests, accompanied by an affidavit. In the motion, and affidavit, the respondent denied being Beth’s natural father, explaining that when Beth was conceived, he and the petitioner were not living together and the petitioner was having sexual relations with another man. The respondent also asserted that he would “continue to have doubts concerning this matter if I were found to be the father of the said Minor Child just because I am married to the Plaintiff, the child’s mother.” The parties reconciled before blood tests were ordered, or taken, and the matter was not further pursued.
The parties separated for the final time in 1989. Pursuant to a Voluntary Separation and Property Settlement Agreement, they agreed to joint custody of the child “born to the parties prior to their marriage,” that the primary residence of the child would be the petitioner’s, and that the respondent would have visitation rights. The agreement also provided that neither party would move from the State of Maryland with Beth without the express consent of the other. The agreement was amended to provide for automatic increases in child support, to make the respondent responsible for the payment of private school tuition, and to require the parties to share the costs of college. It was also amended to make clear that reconciliation would not affect the child support, visitation, custody or property disposition provisions.
The parties also entered into two consent orders. The first, entered into shortly after the separation agreement was signed, confirmed the support, joint custody and visitation arrangements reflected in the agreement, provided for the petitioner and child to reside in the marital home, and [762]*762required the child to resume attendance at private school. In addition to providing for increased support and other expenses for the child, the second consent agreement called for the psychological and psychiatric examination of the parties and Beth to facilitate recommendations as to custody and visitation.
When the petitioner moved, with Beth, from the State of Maryland, the respondent filed a motion for temporary and exclusive custody, which the circuit court granted. Following an emergency hearing, that order was continued in effect, pending an evidentiary hearing. Before the evidentiary hearing could be held, however, the petitioner filed a Motion To Order Blood Tests To Establish Paternity, alleging that the respondent was not Beth’s biological father. The court granted the motion, ordering the respondent to submit to a blood test, which he ultimately did. The results of the test excluded him as Beth’s biological father.
The evidentiary hearing proceeded as scheduled and the blood tests results were admitted into evidence over the respondent’s objection. Following testimony by both parties, as well as from numerous witnesses called on their behalf, and,' notwithstanding the blood test results, the master recommended, inter alia, that temporary custody be continued in the respondent.
Both parties excepted to the master’s recommendations. The petitioner excepted to the temporary custody recommendation and the respondent to the admission into evidence of the blood test results. The court sustained the petitioner’s exceptions and overruled the respondent’s. Consequently, it ordered that temporary custody of Beth be changed from the respondent to the petitioner.1 Adopting the master’s findings that neither party was unfit, the court rejected those pertaining to the existence of exceptional circumstances sufficient to overcome the presumption that [763]*763it was in Beth’s best interest to be in the custody of the petitioner, a biological parent, rather than the respondent, a “third” party. It found, “as a matter of law,” that exceptional circumstances did not exist.
II.
Our opinion in Turner v. Whisted, 327 Md. 106, 111, 607 A.2d 935, 937 (1992) addressed the question:
Whether a male individual who claims to be the father of a child born to a married couple is entitled to petition a circuit court for a blood test to determine paternity for the purpose of determining whether said male individual is the biological father of the child when the child was conceived prior to the marriage of said married couple.
The motion for blood tests filed in that case was premised on Maryland Code (1974, 1991 Repl.Vol.), § 1-208 of the Estates and Trusts Article and Thomas v. Solis, 263 Md. 536, 283 A.2d 777 (1971). We held, in Turner, “that § 1-208 of the Estates & Trusts Article provides an alternate avenue by which one could seek blood tests for the purpose of establishing paternity.” 327 Md. at 113, 607 A.2d at 938. For that conclusion, we relied on Thomas, which held that compliance with § 1-208 was sufficient to protect an unwed father’s visitation rights and right to notice of a proposed adoption. Thomas, 263 Md. at 544-45, 283 A.2d at 781-82. In addition, we noted the interrelationship between the paternity statute, see Maryland Code (1984, 1991 Repl.Vol.), § 5-1001, et. seq. of the Family Law Article and § 1-208, which was recognized in Taxiera v. Malkus, 320 Md. 471, 578 A.2d 761 (1990). See also § 5-1005(a) of the Family Law Article (“An equity court may determine the legitimacy of a child pursuant to § 1-208 of the Estates and Trusts Article.”), and § l-208(b)(l) (the child is legitimate if his or her father “[h]as been judicially determined to be the father in an action brought under the statutes relating to paternity proceedings”). Thus, we held:
[I]n those cases where two men each acknowledge paternity of the same child, we believe that an action to [764]*764establish paternity is more appropriately brought under the Estates and Trusts Article. As advanced by this Court in Thomas and Dawson [v. Eversberg, 257 Md. 308, 262 A.2d 729 (1970) ], the Estates & Trusts Article presents the “more satisfactory” and “less traumatic” means of establishing paternity.
327 Md. at 113, 607 A.2d at 938 (quoting Thomas, 263 Md. at 544, 283 A.2d at 781; Dawson, 257 Md. at 314, 262 A.2d at 732).
Section 1-208 is the preferred mechanism, we explained, because of the discretion it affords the trial court to grant or deny the request for blood tests.2 Under § 1-208, we [765]*765pointed out, “[a] motion for blood tests ... is best analyzed as a request for a physical examination under Maryland Rule 2-423.” Turner, 327 Md. at 113, 607 A.2d at 939. Pursuant to that rule, good cause must be shown for the order of the blood tests, id. at 114, 607 A.2d at 939, the determination of which “allows the court discretion to consider the best interests of the child.” Id. at 116, 607 A.2d at 940. Whether the presumption of legitimacy, which attaches to a child by virtue of his or her mother’s marriage to a man who was married to the mother at the time of conception, and who also acknowledges the child as his, should be rebutted, involves and, indeed, requires the balancing of various interests relevant to the determination of good cause for the blood tests—those of the family unit, those of the man challenging paternity and, most importantly of all, the best interests of the child. Proceeding pursuant to § 1-208 permits these interests to be balanced and, in addition, allows for input from a representative for the child. Id. The court need not, and probably should not, rely on the parties to the action accurately and adequately to define what is in the child’s best interest.
The case was remanded to the trial court for further proceedings, specifically, for the consideration of the child’s best interest prior to the passage of an order requiring [766]*766blood tests. By way of guidance to the trial court, we offered examples of what might constitute criteria for determining the child’s best interest when paternity is disputed: “the stability of the child’s current home environment, whether there is an ongoing family unit, and the child’s physical, mental, and emotional needs.” Id. We also mentioned the child’s past relationship with the putative father and the importance to the child of having available genetic information for medical treatment and genealogical history, as other relevant and important issues. Id.
III.
A.
Rather than being sought in an action to establish paternity, whether pursuant to § 5-1028 of the Family Law Article or § 1-208 of the Estates and Trusts Article, the blood tests in this case are being requested in the context of a child custody dispute between the mother of a child born out of wedlock and the man who has, both before and after their marriage, acknowledged that child as his own and maintained a fatherly relationship with her. Moreover, the purpose for which they are sought is the effect the results will have on the determination of which party should be the child’s custodian; the petitioner does not propose to establish who the biological father actually is. Indeed, the petitioner has made it quite clear that she does not know whether the child’s biological father is living or dead and, if living, where he is. The petitioner quite candidly acknowledges that, if successful, she will seek no support from the biological father, nor will she attempt to foster a relationship between him and the child. She proffers only that the respondent is not Beth’s father and, consequently, should not be her custodian. The desired effect of ordering the blood tests, then, was the disestablishment of the respondent’s paternity, not the establishment, concomitantly or otherwise, of paternity in someone else.
[767]*767Maryland Rule 2-423 permits a court to order, on good cause shown, a mental or physical examination of a party or of a person in the custody or under the legal control of a party when the mental or physical condition or characteristic of that party or person in the party’s custody or legal control is in controversy. The petitioner’s request for blood tests must be analyzed in this context. As a threshold determination, the petitioner must show good cause. It is appropriate for a court to consider the best interest of the child in assessing whether good cause has been shown. Turner v. Whisted, 327 Md. 106, 607 A.2d 935 (1992). If it would not be in the child’s best interest to have the blood tests reveal that a man who has been the de facto father in the whole of the child’s life is not the biological father, surely the circuit court should consider that probability in the exercise of its discretion under the good cause standard. That assessment may only be made by considering the entirety of the relationship between the child, the petitioner and the respondent.
B.
Neither the paternity statute nor § 1-208 is directly implicated in this case—establishing paternity is not a necessary factor to be considered when addressing the issue of custody. The policies and purposes underlying those statutes are, nevertheless, relevant to the determination whether good cause for ordering the blood tests has been shown.
Both the paternity statute3 and § 1-208 are aimed at the legitimation of children born out of wedlock.4 Indeed, to secure for children born out of wedlock, “as nearly as practicable, the same rights to support, care, and education as children born in wedlock,” Taxiera, 320 Md. at 479, 578 A.2d at 765, is their paramount goal.
[768]*768C.
The purpose of legitimation statutes is well served, and, in fact, furthered when, without court proceedings, a child born out of wedlock is legitimated. It matters not whether the result was accomplished pursuant to § 1-208(b)(2), (3), and (4) or pursuant to § 5-1029. Thus, where the party against whom the paternity decree is sought, see Skeens v. Paterno, 60 Md.App. 48, 58, 480 A.2d 820, 825 (1984), or as to whom the determination of paternity would be adverse, see Harvey v. Williams, 319 Md. 238, 246, 572 A.2d 149, 153 (1990), admits paternity, no further judicial proceedings to establish that fact are required. A putative father’s admissions, in pleadings, to being the child’s father obviate the need for a judicial filiation decree,5 as a prerequisite to his seeking custody of, or visitation with, the child whose paternity he admitted. Thomas, 263 Md. at 544, 283 A.2d at 781; Skeens, 60 Md.App. at 58, 480 A.2d at 825. Particularly is the purpose of the legitimation statutes served when, in addition to acknowledging paternity, as, for example, in the manner prescribed in § 1-208, the acknowledged father undertakes, without the necessity of a court order, the basic obligations and responsibilities of parenthood—he maintains a fatherly relationship with the child and provides for its support and care.
D.
In the case sub judice, Beth was conceived before her mother married the respondent. Therefore, the respondent is not, presumptively, Beth’s father. On the other hand, from the time that he was satisfied that he was, as the petitioner advised him, her father, the respondent has acted accordingly. He consented to his name being placed on the birth certificate, he has openly and notoriously acknowledged Beth as his daughter, he has acknowledged paternity [769]*769in writing, i.e., in the separation agreement he and the petitioner executed, and he married Beth’s mother. Thus, he acknowledged his paternity of Beth in three of the four ways enumerated in § 1-208.6
IV.
When a court is called upon to resolve the issue of which of the parties to a child custody action should be awarded custody of a child, the critical and overriding consideration is “what is in the best interest of the child?” McCready v. McCready, 323 Md. 476, 481, 593 A.2d 1128, 1130 (1991); Taylor v. Taylor, 306 Md. 290, 303, 508 A.2d 964, 970 (1986). See also Ross v. Hoffman, 280 Md. 172, 175 n. 1, 372 A.2d 582, 585 n. 1 (1977). It is not simply one of several factors; rather, it is “the objective to which virtually all other factors speak.” Taylor, 306 Md. at 303, 508 A.2d at 970 (1986). That standard permeates the entire proceedings, not simply the bottom line determination of in whose custody the child should be placed. This does not mean, of course, that every bit of evidence sought to be introduced in a child custody case must be assessed, before its admission, in light of the child’s best interest. It does mean, however, that when information which potentially undermines the best interest of the child, as well as the interest sought to be protected by the legitimation statutes, and the policy of this State, it must first be tested in light of that standard. That is precisely what we held in Turner, albeit in the context of contested paternity proceedings. Turner, 327 Md. at 117, 607 A.2d at 940.
The evidence in this case is that, from Beth’s birth, and arguably before, the respondent has, far from simply ac[770]*770knowledging paternity, been Beth’s father.7 In fact, as far as the record reflects, he is the only father she has known. There is also evidence in the record that Beth regards the respondent as her father. Notwithstanding that, for a part of the period, it was without benefit of marriage, the respondent has lived with Beth and her mother, as a family unit, since her birth.
Curiously, in the motion requesting blood tests, the petitioner indicated prior reluctance “to reveal that the plaintiff was not the child’s father because the defendant did not wish to harm the child.” In the affidavit accompanying the motion, while acknowledging that she previously had confirmed to the respondent that he was, the petitioner swore that blood tests are necessary because the respondent “is not the natural father of my child.” Although she admitted that, at one time, she “believed that it was in my child’s best interest that [the respondent] act as the natural father so as to give continuity and structure to her life ..., since [the respondent] is seeking custody at this time, it has become necessary for me to make this information known at this time.” The petitioner also alleged that the respondent knew that he was not the child’s natural father and had, on previous occasions, denied paternity.
From the motion, and the accompanying affidavit, clearly, the only basis for requesting blood tests is the petitioner’s desire to prove that the respondent is not Beth’s biological father. Indeed, her motion for blood tests is explicit in that regard. From the motion and affidavits it may also be inferred that the petitioner now believes that Beth’s best interest lies in her being in the petitioner’s sole custody, which requires the termination of the relationship, as it has [771]*771developed, between the child and the respondent. As noted earlier, she neither offers, nor intends, to establish substitute paternity. Rather, she intends only that her paramour will adopt Beth.
To justify ordering blood tests, at the behest of the mother, under circumstances in which the only effect of results favorable to the mother would be to show that a man who has acted as the child’s father, who the child regards as her father, who has acknowledged the child, and who is married to the child’s mother is, in fact, not the child’s father requires a showing by the mother that to do so is in the best interest of the child. In the Matter of the Marriage of Ross, 245 Kan. 591, 783 P.2d 331, 338 (1989) (“Prior to ordering a blood test to determine whether the presumed parent is the biological parent, the district court must consider the best interests of the child, including physical, mental, and emotional needs.”); In the Matter of the Marriage of Zodrow, 240 Kan. 65, 727 P.2d 435, 440 (1986) (same); Ban v. Quigley, 168 Ariz. 196, 812 P.2d 1014, 1017 (App.1990) (Strong public policy of preserving the family unit requires consideration of best interest of the child before or during blood tests at the behest of putative father when neither mother nor presumptive father questions the latter’s paternity.). See also Sandy M. v. Timothy J., 138 Misc.2d 338, 524 N.Y.S.2d 639, 642-43 (Fam.Ct.1988); Boyles v. Boyles, 95 A.D.2d 95, 466 N.Y.S.2d 762, 765 (3 Dept.1983). This is especially so when, as here, one means of legitimation was the parties’ marriage, after which they held the child out as being their legitimate issue. Boyles, 466 N.Y.S.2d at 765.
The best interest of a child born out of wedlock but subsequently treated as if it were the legitimate issue of the man who married its mother is not necessarily served by establishing that that man is not the biological father, without a concomitant establishment of paternity in someone else. At the very least, however, blood tests ought not be ordered without considering factors bearing on the issue. See Turner, 327 Md. at 117, 607 A.2d at 940. See also In [772]*772the Matter of the Marriage of Ross, 783 P.2d at 338; MacDaniels v. Carlston, 108 Wash.2d 299, 738 P.2d 254, 261 (1987).
Where there is disputed paternity, i.e., two men are competing for custody, Turner made clear that the putative father’s motive for pursuing the action—“[his] commitment to the responsibilities of parenthood,” Turner, 327 Md. at 117, 607 A.2d at 940, and his interest in establishing a relationship with the child—must be balanced against the interest of the presumptive father, and his family, in maintaining an already formed familial relationship. Id. The best interest of the child, evidence as to which may come from the child’s representative, informs the proper balance. See Turner, 327 Md. at 116, 607 A.2d at 940.
A similar weighing process must be conducted where there is neither a putative father nor a presumptive father vying for the child’s paternity, but only a man, who has treated the child as his own, locked in combat with the child’s mother on the issue. The factors identified in Turner apply with equal force to the best interest inquiry in such a case; the respondent is in a position comparable to that of a presumptive father under § 5-1028(c). Thus, the petitioner’s interest in obtaining sole custody must be considered and balanced against those of the respondent in protecting the relationship he has formed, and maintained, with the child. In addition, the petitioner’s motive in seeking to disestablish, after prior acquiescence in, the respondent’s paternity without any attempt to establish another’s must also be considered. So too, must Beth’s physical, mental, and emotional needs. And, because there is no attempt to establish biological paternal parentage, it is relevant that no genetic information will be generated for use medically or historically. The purpose of this analysis is, of course, to determine what is in the child’s best interest. On that question, input from the child’s representative, which the court may appoint, see Turner, 327 Md. at 116, 607 A.2d at 640, could be important. Significant to the best interest determination is the desirability, from the [773]*773child’s perspective, of establishing that the man that is the only father the child has ever known, the husband of the child’s mother, and who has acknowledged the child, is, in fact, not the child’s father. The effect of that determination is not only to establish that the person who the child regarded as her father, is, in fact, not her father, but also to establish that she has no known father.
The trial court did not consider, when ordering the blood tests in connection with this custody dispute, whether to do so was in the child’s best interest. In so doing, the court erred. Turner, 327 Md. at 117, 607 A.2d at 940. The court also erred in overruling the respondent’s exception to the master’s admission of the blood tests results into evidence.
Ordinarily, we would remand the case for consideration of the issue in light of the principles we have enumerated. We do not do so in this case, however, because the cat is now out of the bag and cannot now be stuffed back in. But see In the Matter of the Marriage of Ross, 783 P.2d at 339 (even though “the blood tests have already been performed ..., the court [on remand] shall not consider the results of the tests until such consideration is determined to be in the child’s best interests”). Nor will we require the trial court to again consider temporary, rather than permanent, custody; the uncertainty of its outcome and its potential impact on the stability of the child’s life make another interim custody decision inappropriate. See Domingues v. Johnson, 323 Md. 486, 500, 593 A.2d 1133, 1139 (1991).
V.
Even though the known blood tests results have been admitted into evidence, the trial court still has to make a custody decision, only it must do so in light of the standard enunciated in Ross v. Hoffman, 280 Md. at 178-79, 372 A.2d at 587:
the best interest of the child standard is always determinative in child custody disputes. When the dispute is between a biological parent and a third party, it is pre[774]*774sumed that the child's best interest is subserved by custody in the parent. That presumption is overcome and such custody will be denied if (a) the parent is unfit to have custody, or (b) if there are such exceptional circum- • stances as [to] make such custody detrimental to the best interest of the child.
Using its independent judgment, the court's task is to determine whether there exists sufficient exceptional circumstances to rebut the presumption that custody should be. awarded to the biological parent. Aware of the latter responsibility, in the case sub judice, relying on the blood tests results, the court found that, because the respondent was not the biological father, he was a third party and, then, using the Ross v. Hoffman standard, supra, proceeded to resolve the custody dispute.
The master had recommended that custody remain with the respondent because exceptional circumstances rebutting the presumption existed. The court disagreed and sustained the petitioner's exceptions challenging that recommendation, reasoning:
There is a long line of cases discussing the special circumstances required to overcome the presumption, that it is in the best interest of the child to be with the biological parent. Piotrowski v. State, 179 Md. 377[, 381, 18 A.2d 199] (1941); Dietrich v. Anderson, 185 Md. 103[, 116, 43 A.2d 186] (1945); Ross v. Pick, 199 Md. 341[, 351, 86 A.2d 463] (1952); Trenton v. Christ, 216 Md. 418[, 420, 140 A.2d 660] (1958); Melton v. Connolly, 219 Md. 184[, 188, 148 A.2d 387] (1959). In these cases the child had been separated from the biological parents for long periods of time (the shortest period found was four and one-half years) and it was thought that it would not be in the best interest of the child to be uprooted from a stable environment in which they lived for so long a time. It was also true that these children had spent almost their entire life separated from the biological parent.
This is not the circumstances of the case at bar. In this case the child has been separated from her biological [775]*775mother for six months and prior to that had always lived with her mother.
In assessing whether there are exceptional circumstances, the critical question remains, what is in the best interest of the child? The “best interest” standard “ ‘is an amorphous notion, varying with each individual case....’” Domingues, 323 Md. at 499, 593 A.2d at 1139 (quoting Montgomery County v. Sanders, 38 Md.App. 406, 419, 381 A.2d 1154, 1163 (1978)). That determination cannot be made simply by considering the amount of time a parent may have been separated from the child, or even by characterizing the dispute as being between a “biological parent” and a “third party.” See Durkin v. Hinich, 442 N.W.2d 148, 153 (Minn. 1989); Normand By and Through Normand v. Ray, 109 N.M. 403, 785 P.2d 743, 747-48 (1990). What is important, rather, is the relationship that exists between the child and each of the parties. The ramifications of a change in those relationships are also critical. Likewise, the importance to the child’s stability of having one, as opposed to another, or both, of the relationships continue must be considered as well. See Domingues, 323 Md. at 498, 593 A.2d at 1139.
The cases relied on by the trial court do not exhaustively or finally define the universe of circumstances sufficiently exceptional as to warrant resolving a custody dispute against a biological parent and in favor of a third party. Whether the child has established a relationship with a third party sufficient to constitute exceptional circumstances, rebutting the presumption of custody in the biological parent, is not dependent on its development during the absence of the biological parent. A relationship resulting in bonding and psychological dependence upon a person without biological connection can develop during an ongoing biological parent/child relationship. Particularly is this true when the relationship is developed in the context of a family unit and is fostered, facilitated and, for most of the child’s life, encouraged by the biological parent. That the relationships, one with a known biological parent and the other with [776]*776an acknowledged, though, in fact, non-biological, parent, progress at the same time, does not render either less viable.8
In the present case, that the respondent is not Beth's father is only fortuitous. Prior to her birth, having been told, and after investigation, having come to believe, that she was his child, he allowed his name to be placed on the birth certificate as her father and proceeded to act as her father. He was present in the delivery room when she was born and he lived with her and her mother, with the exception of periods of separation, both before and after he married her mother, from the time of Beth’s birth. He has, in short, treated the child as if she were his biological child from the time of her birth up to, and beyond, the determination that he is not. From the time of her birth, until recently, and then only for a short time, Beth lived in Baltimore County. For much of that time, she lived with the petitioner and the respondent. Even when she was placed in the physical custody of the petitioner, the respondent, pursuant to the separation agreement, exercised liberal visitation. Indeed, he had joint custody with the petitioner. The evidence at the hearing further tended to prove that the child viewed the respondent as her father; she is bonded to him, and he to her. According to Dr. Leon Rosenberg, the respondent is Beth’s psychological father. For discussion of concept of “psychological parent,” see Sanders, 38 Md.App. at 412-13, 381 A.2d at 1159.9
[777]*777On the other side of the ledger, aside from the relationship between Beth and the petitioner, no evidence was presented concerning what Beth’s living arrangements would be were custody to be transferred to the petitioner. Nor was there evidence presented as to the relationship that exists between Beth and her mother’s paramour.
We conclude that there was ample evidence to support the master’s determination that exceptional circumstances existed in this case to rebut the presumption that Beth’s best interest lay with being in the custody of her mother. From this evidence, a trier of fact could find, as the master did, exceptional circumstances. In any event, the issue is not one that can be resolved as a matter of law.
The trial court focused upon the absence of one of the exceptional circumstances our courts have considered sufficient to rebut the presumption of custody in the natural parent and, because that circumstance did not exist, determined, as a matter of law, that no exceptional circumstances existed in this case. In so doing, the court erred.
We do not, of course, express any opinion as to the outcome of this custody matter. We do not wish to suggest that, on remand, custody could not be awarded to the petitioner; it certainly could. We simply wish to provide guidance for the trial court in addressing the issue of permanent custody. We want to make clear that, using its independent judgment, the court has to determine whether the circumstances of this case are sufficiently exceptional as to rebut the presumption that custody should be awarded to the petitioner.
