Madsen, J.
The question presented by these three consolidated cases is whether the 1997 amendments to [323]*323RCW 13.50.050, relating to vacation and sealing of juvenile court records, apply to the records of defendants who were eligible for expungement before the amendments were adopted but who moved for relief after the amendments became effective. In State v. D.V., No. 93-8-06285-2 (King County Super. Ct. Aug. 10, 1998), and State v. C.C., No. 91-8-01326-0 (King County Super. Ct. Oct. 20, 1998), the State Patrol appeals directly from a superior court order granting defendants’ motions to seal juvenile files. In State v. T.K., 94 Wn. App. 286, 971 P.2d 121 (1999), the State petitions for review of a published Court of Appeals’ decision directing the superior court to seal defendant’s records. We affirm the trial courts in D.V and C.C. and the Court of Appeals in T.K.
Facts
State v. T.K.
T.K. pleaded guilty to first degree child molestation in March 1993. The prosecutor recommended, and the court imposed, treatment under a special sex offender disposition alternative (SSODA). At that time, RCW 13.50.050(10) and (11) permitted juvenile offenders to petition the court to vacate disposition orders and to permanently seal juvenile court files two years after the juvenile was discharged from state agency supervision. If the juvenile had committed no other offenses, that statute required the juvenile court to grant the motion to vacate and seal.
T.K. completed the requirements of his SSODA in April 1995. In 1996, he petitioned the juvenile court to vacate his duty to register his residential address under the sex offender registration statute, RCW 9A.44.140(4). The court found the defendant met the demands of the statute and entered an order ending the registration requirement. T.K. did not, however, move to have his disposition orders vacated or his conviction records sealed under RCW 13.50.050.
In 1997, the Legislature amended RCW 13.50.050(11) to require sealing under subsection (10) only if the moving party has spent 10 consecutive years in the community [324]*324without committing any additional offenses in the case of a Class B felony and 5 years for a Class C felony conviction. It also ehminated sealing altogether if the original offense was a sex offense or a class A felony. Laws of 1997, ch. 338, § 40. The effective date of the amendments was July 1, 1997. Laws of 1997, ch. 338, § 75. In October 1997, T.K. moved the court to order the Washington State Patrol to expunge the record of his juvenile court conviction. The court denied the motion based on the 1997 amendments to RCW 13.50.050.
The Court of Appeals, Division One, held that the 1997 amendments could not divest T.K. of the right to have his records sealed because he satisfied all of the requirements for expungement under the pre-1997 version of the statute. The court therefore reversed and remanded with directions that T.K.’s records be expunged.
State v. D.V
While trick-or-treating on Halloween night in 1992, D.V forcibly took bags of candy from other teenagers. D.V pleaded guilty to two counts of second degree robbery. The court entered its disposition order in November 1993.1 On July 14, 1998, D.V filed a motion to seal the juvenile court records under his juvenile court cause number pursuant to RCW 13.50.050. The trial court found he had met the requirements of RCW 13.50.050 prior to the 1997 amendments. Therefore, the court held that D.V had a right to have his records sealed under the former statute and issued an order to the Washington State Patrol to seal the records.
The State Patrol notified D.V’s attorney that it declined to comply with the order as it had not been notified of the motion and was not a party to the proceedings. D.V then re-noted his motion and sent notice of the hearing to the State Patrol. At the second hearing the judge again ordered the State Patrol to seal D.V’s records because he had [325]*325become eligible for expungement prior to the 1997 amendments. The State Patrol appealed directly to this court.
State v. C.C.
C.C. pleaded guilty to the charge of rape of a child in the first degree in 1991. In September 1998, C.C. filed a motion to seal his juvenile records. The trial court granted the motion and entered an order sealing the juvenile records. The State Patrol appealed directly to this court.
These three cases have been consolidated for review by this court.
Analysis
RCW 13.50.050(10) provides that an individual against whom an information has been filed under RCW 13.40.100 or who has been referred for diversion pursuant to RCW 13.40.070 “may file a motion with the court to have the court vacate its order and findings” and “order the sealing of the official juvenile court file, the social file, and records of the court and of any other agency in the case.” Prior to July 1997, RCW 13.50.050(11) mandated:
The court shall grant the motion to seal records made pursuant to subsection (10) of this section if it finds that:
(a) Two years have elapsed from the later of: (i) Final discharge of the person from the supervision of any agency charged with supervising juvenile offenders; or (ii) from the entry of a court order relating to the commission of a juvenile offense or a criminal offense;
(b) No proceeding is pending against the moving party seeking the conviction of a juvenile offense or a criminal offense; and
(c) No proceeding is pending seeking the formation of a diversion agreement with that person.
Former RCW 13.50.050(11) (1996).
In 1997, the Legislature amended RCW 13.50.050(11) as follows:
[326]*326The court shall grant the motion to seal records made pursuant to subsection (10) of this section if it finds that:
(a) For class B offenses other than sex offenses, since the last date of release from confinement, including full-time residential treatment, if any, or entry of disposition, the person has spent ten consecutive years in the community without committing any offense or crime that subsequently results in conviction. For class C offenses other than sex offenses, since the last date of release from confinement, including full-time residential treatment, if any, or entry of disposition, the person has spent five consecutive years in the community without committing any offense or crime that subsequently results in conviction;
(b) No proceeding is pending against the moving party seeking the conviction of a juvenile offense or a criminal offense;
(c) No proceeding is pending seeking the formation of a diversion agreement with that person;
(d) The person has not been convicted of a class A or sex offense; and
(e) Full restitution has been paid.
RCW 13.50.050(11). The effective date of the 1997 amendment was July 1, 1997. Laws of 1997, ch. 338, § 75.
Initially, the State contends the trial court exceeded its authority in ordering sealing of the defendants’ records because “[t]he statute relied on by the Juvenile Court did not exist when it made its ruling.” Br. of Appellant Wash. State Patrol, State v. D.V., at 7; see also Br. of Appellant Wash. State Patrol, State v. C.C., at 6. Citing State v. Gilkinson, 57 Wn. App. 861, 865, 790 P.2d 1247 (1990), the State argues that the trial court has no inherent power to resuscitate the terms of a previous statute (former RCW 13.50.050(11)) and apply them to the defendants’ cases. Br. of Appellant Wash. State Patrol, State v. D.V., at 8. Gilkinson does not support the State’s position. At issue there was RCW 10.97.060 which provided for deletion of noncon[327]*327viction data upon the request of the subject of such data. Gilkinson, 57 Wn. App. at 864. RCW 10.97.030(2) defined nonconviction data and RCW 10.97.030(4) excluded from the definition of nonconviction data any dismissal entered after probation, suspension, or deferral of sentence. The defendant conceded that deletion of his deferred sentence was not authorized under the relevant statutes. He argued, however, that the trial court had the inherent power to delete records of his conviction. The Court of Appeals disagreed, concluding that a trial court has no inherent authority to expunge a criminal record and that the authority to do so must come from the Legislature. Thus, the question in Gilkinson was not whether a statute which is amended ceases to exist, but whether a trial court has inherent authority to expunge criminal records, in addition to any express statutory authority. In these cases, the trial court and the Court of Appeals did not purport to rely on an inherent court power. They relied on the language of the preamendment statute.
Contrary to the State’s argument, amending a statute does not necessarily mean that the prior statute ceases to exist. An amendment generally means that the new statute will apply as of the effective date of the amendment. There are many cases, however, in which a preamendment version of a statute will continue to govern in cases arising prior to the amendment, particularly where vested rights or contractual obligations are affected. See, e.g., In re F.D. Processing, Inc., 119 Wn.2d 452, 461-62, 832 P.2d 1303 (1992) (in action relating to statute extending lien protection to agricultural processors, preamendment version of statute governs because amendment to definition of agricultural products affected bank’s vested right in a security interest and, therefore, not retroactively applied); Ashenbrenner v. Department of Labor & Indus., 62 Wn.2d 22, 25, 380 P.2d 730 (1963) (rights of workmen’s compensation claimants are controlled by law in force at time of injury rather than by law which becomes effective subsequently); Procter & Gamble Co. v. King County, 9 Wn.2d [328]*328655, 656, 115 P.2d 962 (1941) (in foreign corporation’s action to recover taxes paid to county under protest, court held that rights had accrued and were not modified or terminated by repeal of that statute so that corporation was not required to prove it “had never conducted any business” in the state); see also 2 Norman J. Singer, Statutes and Statutory Construction §§ 41.05-.07 (5th ed. 1997). Indeed, case law discussing prospectivity and retroactivity of statutory amendments abounds.2
The State next argues that the 1997 amendments apply to all records for which a request to seal is made after July 1, 1997. Since the defendants did not move for vacation and sealing of records until after the effective date of the amendments, the State contends that the requirements of [329]*329the amended statute must be met. The defendants reply that the 1997 amendments do not apply if the moving party met the statutory requirements for sealing the documents under the prior statute before it was amended. For this discussion, both the State and the defendants agree the 1997 amendments operate prospectively. However, the defendants believe that adopting the State’s position will nevertheless result in a retroactive application of the amendment.
To decide whether the 1997 amendments apply in these cases, we must look first to the language of the statute. If a statute is clear and unambiguous, a court may not look beyond the language of the statute. Everett Concrete Prods., Inc. v. Department of Labor & Indus., 109 Wn.2d 819, 822, 748 P.2d 1112, 7 A.L.R.5th 1086 (1988). Here, the 1997 amendments do not make clear whether the Legislature intended the new rules to apply to requests to seal records made after July 1, 1997, the effective date of the amendment, or only to requests involving juvenile records created after that date. Therefore, it is necessary to rely on rules of statutory construction to determine the meaning of the statute. In re Juveniles A, B, C, D, E, 121 Wn.2d 80, 88, 847 P.2d 455 (1993). In construing the statute, the Court’s goal is to give effect to the Legislature’s intent. State v. Elgin, 118 Wn.2d 551, 555, 825 P.2d 314 (1992).
A statute is presumed to operate prospectively unless the Legislature indicates that it is to operate retroactively. Landgraf v. USI Film Prods., 511 U.S. 244, 264-66, 114 S. Ct. 1522, 128 L. Ed. 2d 229 (1994); State v. McClendon, 131 Wn.2d 853, 861, 935 P.2d 1334, cert. denied, 522 U.S. 1027 (1997); In re Estate of Burns, 131 Wn.2d 104, 110, 928 P.2d 1094 (1997); Adcox v. Children’s Orthopedic Hosp. & Med. Ctr., 123 Wn.2d 15, 30, 864 P.2d 921 (1993); In re Dissolution of Cascade Fixture Co., 8 Wn.2d 263, 272, 111 P.2d 991 (1941). Courts disfavor retroactivity. In re Estate of Burns, 131 Wn.2d at 110. A statute operates prospectively when the precipitating event for its application occurs after the effective date of the statute. Aetna [330]*330Life Ins. Co. v. Washington Life & Disability Ins. Guar. Ass’n, 83 Wn.2d 523, 535, 520 P.2d 162 (1974). “A statute does not operate ‘retrospectively’ merely because it is applied in a case arising from conduct antedating the statute’s enactment ... or upsets expectations based in prior law.” Landgraf, 511 U.S. at 269 (quoting Republic Nat’l Bank v. United States, 506 U.S. 80, 100, 113 S. Ct. 554, 121 L. Ed. 2d 474 (1992)). To determine the precipitating event giving rise to application of a statute, a court may look to the subject matter regulated by the statute. In re Estate of Burns, 131 Wn.2d at 112.
The State argues that application of the 1997 amendments to these defendants would not result in retroactive application of the amendment because the event which triggers the statute is the motion to seal which occurred after the effective date of the amendment. The State offers two rationales for its position. First, it argues that the plain language of the 1997 amendment provides that the precipitating event for its application is the motion to seal. For support the State cites this court’s recent decision in State v. Blank, 131 Wn.2d 230, 930 P.2d 1213 (1997). The issue there was whether application of a statute concerning attorney fees and costs of litigation following appeal involved retroactive application of a statute when applied to a defendant who had filed his appeal prior to adoption of the statute but before completion of his appeal. The court held that since the precipitating event for application of the statute was the termination of the appeal and affirmance of the defendant’s conviction, the statute did not operate retroactively in the defendant’s case. Id. at 249-50. Blank does not aid the State’s position. The language in the statute at issúe in Blank made it clear that the completion of the appeal was the triggering event for application of the fees and costs. As mentioned above, RCW 13.50.050 simply does not indicate the triggering event. Moreover, it made sense in Blank that the fee statute would be triggered only by completion of the appeal rather than filing the notice of appeal because a defendant whose conviction is reversed is under no obligation to pay those fees.
[331]*331Next, the State contends that the reasoning of In re Estate of Burns compels the conclusion that the motion to seal is the precipitating event. Under the approach announced in In re Estate of Burns, the court looks to the subject matter regulated by the statute to determine the precipitating event. The State contends that the subject matter regulated by RCW 13.50.050(10) and (11) is the keeping and release of records hy juvenile justice or care agencies. It argues that the motion to seal is an event within the subject matter regulated by the statute, whereas sentence completion and nonreoffending “are subjects very different from records maintenance.” State’s Answer to ACLU Amicus Curiae Br. at 7. Thus, the State concludes that the filing of the motion must be the precipitating event for application of the statute.
As the defendants point out, RCW 13.50.050(10) and (11) define the conditions under which a juvenile offender may have his disposition vacated and his records sealed. The completion of those conditions is within the subject matter regulated by the statute. Further, the statute both before and after the 1997 amendments says the court “shall” grant a motion to seal, imposing a mandatory obligation to seal if a juvenile meets the statutory conditions. Accordingly, once the conditions of the statute are met, the defendant has a right to relief and a court has the nondiscretionary obligation to seal records regardless of when the motion is made. State v. Webster, 69 Wn. App. 376, 378-79, 848 P.2d 1300 (1993).
Our decision in State v. Hodgson, 108 Wn.2d 662, 740 P.2d 848 (1987), is also helpful in resolving this issue. In Hodgson, this court considered the application of an amendment which extended a criminal statute of limitations. Rather than becoming bogged down in labels such as “prospective” and “retrospective,” “procedural” or “substantive,” the court recognized that statutes of limitations are matters of legislative grace. Id. at 667. Relying on Falter v. United States, 23 F.2d 420, 425-26 (2d Cir.), cert. denied, 227 U.S. 590, 48 S. Ct. 528, 72 L. Ed. 1003 (1928) [332]*332and People ex rel. Reibman v. Warden of County Jail, 242 A.D. 282, 285, 275 N.Y.S. 59 (1934), the court observed that “ ‘[u]ntil the statute has run it is a mere regulation of the remedy . . . subject to legislative control. Afterwards it is a defense, not of grace, but of right, not contingent, but absolute and vested, . . . not to be taken away by legislative enactment.’ ” Hodgson, 108 Wn.2d at 668 (quoting Warden, 242 A.D. at 285). Although RCW 13.50.050(10) and (11) are not statutes of limitations, the analysis is similar. Just as the passage of a specified period of time triggers application of a statute of limitations, completing the conditions of the sealing statute triggers its application. Thus, just as dismissal is required when the specified time period has passed without a change in the statute of limitations, expungement is required if conditions for expungement were satisfied before those conditions were changed.
Considering the subject matter addressed by the provisions in question and the mandatory language of the statute we conclude that completion of the statutory conditions, not the filing of a motion to seal, is the event that triggers application of the statute. Consequently, assuming the 1997 amendments apply prospectively as both parties contend, the amendments do not apply to the motions made in these consolidated cases.
The State alternatively urges that if this application of the amendments to juveniles who met the criteria prior to the amendment is retroactive, then the court should find that the statute is remedial and that retroactive application will further its remedial purpose. Defendants counter that none of the exceptions to prospectivity apply to the 1997 amendments.
The presumption of prospectivity can be overcome if (1) the Legislature explicitly provides for retroactivity, Landgraf, 511 U.S. at 270, 278; (2) the amendment is “curative,” In re F.D. Food Processing, Inc., 119 Wn.2d at 461-62; or (3) the statute is “remedial,” McClendon, 131 Wn.2d at 861.
A remedial statute is one which relates to [333]*333practice, procedures, and remedies. McClendon, 131 Wn.2d at 861. A remedial statute will ordinarily be applied retroactively unless to do so affects a substantive or vested right. Id. Here the State asserts the statute and its amendments are remedial because they are designed to protect the public by maintaining records of serious offenders and by extending the time spent in the community by juveniles convicted of lesser offenses to demonstrate rehabilitation. The State also contends the amendments are procedural, merely regulating record keeping.
The distinction between remedial statutes, substantive statutes, retroactivity and prospectivity is frequently blurred. Lewis H. Orland, a noted professor and writer in the area of civil procedure, has observed that the “substance-procedure dichotomy . . . does not provide a desirable analytical base.” Lewis H. Orland & David G. Stebings, Retroactivity in Review: The Federal and Washington Approaches, 16 Gonz. L. Rev. 855, 880 n.133 (1981). As former Chief Justice Andersen said in Hodgson, 108 Wn.2d at 667, labeling of statutes as “procedural” or “substantive,” “prospective” or “retrospective,” or “retroactive” tends to obscure rather than clarify the law.
Even if the 1997 amendments at issue here are remedial, a statute will not be applied retroactively if it affects a substantive or vested right. McClendon, 131 Wn.2d at 861; In re F.D. Food Processing, Inc., 119 Wn.2d at 462-63. The Court of Appeals in State v. T.K., and the trial court in State v. D.V. and State v. C.C., held that the defendants’ statutory right to have records sealed had accrued prior to the amendment and no later-enacted statute could divest them of the right. The Court of Appeals analogized RCW 13.50.050(11) to a statute of limitations. Citing Merrigan v. Epstein, 112 Wn.2d 709, 773 P.2d 78 (1989) the court pointed out that Washington courts preserve claims which accrue prior to enactment of new statutes of limitation and, accordingly, run the statute of limitations from the new statute’s effective date. State v. T.K., 94 Wn. App. 286, 291, 971 P.2d 121 (1999).
[334]*334The State finds fault with the court’s discussion of accrued rights and its reliance on Merrigan. It argues that Merrigan involved interpretation of the tort reform act, RCW 4.16, and does not support the Court of Appeals’ holding that a juvenile has a vested right to have his records sealed. These arguments demonstrate a misunderstanding of the Court of Appeals’ opinion. The court did not find that all juveniles have a vested right to expungement. Rather, the court said that since T.K. had completed the statutory requirements for sealing prior to the 1997 amendment, his right to relief had accrued.
We find the Court of Appeals’ analogy to statutes of limitations apt. In Hodgson, 108 Wn.2d 662, the court concluded that a statute of limitations is a matter of legislative grace and may be changed or repealed in any case where the right to a dismissal has not been absolutely acquired by the completion of the running of the statutory period. Id. at 667. Until the statute runs it merely regulates a remedy. After it has run, however, it becomes a defense which is “absolute and vested.” Id. at 668. As with a statute of limitations, the right to sealing of records under former RCW 13.50.050(11) is contingent only upon spending two years in the community crime free. In each of the cases involved here the juvenile offenders completed the statutory requirements prior to the 1997 amendment. Pursuant to the statutory language, completion of these requirements mandated sealing. As in Hodgson, the right to sealing became absolute upon completion of the statutory conditions.
Finally, the State urges that a party has no vested right in the continuation of existing statutory law, citing Vashon Island Comm, for Self-Gov’t v. State Boundary Review Bd., 127 Wn.2d 759, 768-69, 903 P.2d 953 (1995). State’s Pet. for Review, State v. T.K., at 7. Relying on this notion of “vested rights,” the State contends that no rights vest unless a timely application is filed during the effective period of the ordinance under which a juvenile is seeking relief. Id. The [335]*335Court of Appeals properly rejected the State’s invitation to import land use principles into cases like these.
Conclusion
The precipitating event for application of RCW 13.50-.050(11) is satisfaction of the statutory conditions, thus, prospective application of the 1997 amendment does not affect those juveniles who have spent two years in the community without reoffending prior to the adoption of the 1997 amendment. Moreover, the 1997 amendments may not be applied retroactively in these cases because a substantive right is affected. The trial courts in State v. D.V and State v. C.C. are affirmed as is the Court of Appeals in State v. T.K..
