The issue presented is whether, pursuant to 12 O.S.1981 § 1280,1 a marriage con-

traded in another state in violation of the statute’s six-month prohibition against remarriage is valid in Oklahoma. Because 12 O.S.1981 § 1280 prohibits only those marriages celebrated within Oklahoma during the six-month period following a divorce, we find that a marriage conducted in another state during the statute’s six-month prohibition against remarriage is valid.

FACTS

The appellant, Etzell H. Copeland (Copeland/husband), obtained a divorce from his first wife on December 10, 1986. On January 5, 1987, Copeland and the appellee, Dora “Dot” Stone (Stone/wife), were married in Nevada. The couple stayed three days in Nevada before returning to live together in Oklahoma for approximately three weeks. Copeland and Stone did not live together at any time after January, 1987; and no children were born of the marriage. On June 10, 1987, the six-month prohibition against remarriage imposed by 12 O.S.1981 § 12802 expired. Copeland married a third woman on July 22, 1987.

On March 28, 1988, Copeland filed for divorce naming Stone as defendant. The trial court conducted a hearing on August 18, 1989, to determine the validity of the Nevada marriage in Oklahoma. Finding that the couple did not cohabit beyond the six-month prohibitory period imposed by 12 O.S.1981 § 1280, the trial court found that the union had not ripened into a common law marriage and that it was void. The Court of Appeals affirmed. We granted certiorari on July 9, 1992, to reexamine our *756prior jurisprudence3 and to consider a single issue4 — whether, pursuant to 12 O.S. 1981 § 1280, a marriage contracted in another state in violation of the statute’s six-month prohibition against remarriage is valid in Oklahoma.

BECAUSE 12 O.S.1981 § 1280 PROHIBITS ONLY THOSE MARRIAGES CELEBRATED WITHIN OKLAHOMA DURING THE SIX-MONTH PERIOD FOLLOWING A DIVORCE, A MARRIAGE CONDUCTED IN ANOTHER STATE DURING THE STATUTE’S SIX-MONTH PROHIBITION AGAINST REMARRIAGE IS VALID IN OKLAHOMA.

Copeland asserts that his Nevada marriage is valid. He insists that the clear language of 12 O.S.1981 § 12805 prohibits only those marriages contracted in Oklahoma within six months of a divorce. Stone argues that because she and Copeland did not cohabit beyond the period of impediment imposed by § 1280, the marriage is void. She finds support in our prior jurisprudence.6

The determination of legislative intent controls statutory interpretation.7 However, it is unnecessary to apply rules of statutory construction if the legislative will is clearly expressed.8 Title 12 O.S.1981 § 1280 provides that it is unlawful for either party to a divorce whose spouse is living to “... marry in this state a person other than the divorced spouse within six (6) months from date of decree of divorce granted in this state, or to cohabit with such other person in this state during said period if the marriage took place in another state ...”. The express language of the statute prohibits only those marriages celebrated in Oklahoma within six months following a divorce. Additionally, the statute addresses the situation presented here — marriage outside Oklahoma. It provides that it is unlawful for the couple to reside together during the six-month prohibitory period. However, it does not restrict out-of-state marriages. Parties entering into such marriages are subject to a charge of adultery if they return to Oklahoma to reside during the six-month period following divorce.9

This Court may not, through the use of statutory construction, change, modify or amend the expressed intent of the *757Legislature.10 Pursuant to 12 O.S.1981 § 1280, the Oklahoma Legislature has restricted remarriage within the six-month prohibitory period to those marriages contracted within Oklahoma. We may not extend that prohibition to marriages conducted outside the state. Because 12 O.S.1981 § 128011 prohibits only those marriages celebrated within Oklahoma during the six-month period following a divorce, we find that a marriage conducted in another state during the statute’s six-month prohibition against remarriage is valid. This finding is in accord with the majority of jurisdictions which have analyzed statutes similar to § 1280 or decrees containing the statutory language and have determined that the statutes have no extra-territorial effect.12

We recognize that our holding today, restricting the effect of the six-month prohibitory period contained in § 1280 to marriages contracted within Oklahoma, conflicts with prior case law. Wasson v. Carden, 594 P.2d 1223, 1225 (Okla. 1979); Hess v. Hess, 198 Okl. 130, 176 P.2d 804, 804-05 (1947); Branson v. Branson, 190 Okl. 347, 123 P.2d 643, 645 (1942); Mantz v. Gill, 147 Okl. 199, 296 P. 441, 444 (1931); Mudd v. Perry, 108 Okl. 168, 235 P. 479, 484 (1925); and Estate of Rodgers, 569 P.2d 536, 539 (Okla.App. 1977), all concerned marriages conducted outside Oklahoma within the six-month period of disability imposed by § 1280 and its predecessor statutes. In Wasson, Hess, Branson, Mantz, and Mudd, this Court characterized these mar*758riages as voidable within the six months following the remarriage. However, because the parties continued to live together as husband and wife beyond the disability period, we held that the unions ripened into valid common law marriages. In Rodgers, the Court of Appeals relied upon the same rationale expressed in our jurisprudence. It held that the death of a spouse before the expiration of the six-month waiting prohibited a party to the voidable marriage from being appointed as the administratrix of the deceased spouse’s estate.

Hess, Branson, Mantz, and Mudd were all decided under prior versions of § 1280 which specifically provided that it was unlawful for either party to a divorce to marry another person in any state within six months of the divorce decree.13 The statute was amended in 1969, and the Legislature adopted language prohibiting only those marriages contracted in Oklahoma within six months after a divorce.14 Wasson and Rodgers, both decided after the 1969 amendment, do not analyze the 1969 amendment to § 1280. The prohibition contained in 12 O.S.1981 § 1280,15 first appearing in the 1969 amendment, to remarriage within six months of a divorce does not apply to marriages solemnized outside of Oklahoma. To the extent that Wasson and Rodgers may be read to require cohabitation past § 1280’s six-month prohibitory period to validate an out-of-state marriage, they are hereby expressly overruled. This pronouncement should not be construed to affect any other penalty for cohabitation in Oklahoma within the six-month prohibition period of § 1280.

It is clear that under § 1280 only those marriages contracted in Oklahoma during the six months following a divorce are prohibited. However, an apparent conflict exists between the language of § 1280 and 12 O.S.Supp.1981 § 1282.16 Section 1282 addresses the time when divorce decrees become final and the effect on an appeal. It provides that neither party to a divorce may marry another person within six months of a divorce. Section 1282 does not, as does § 1280, differentiate between marriages conducted within and outside Oklahoma. Section 1282 was amended contemporaneously with the 1969 amendment to § 1280. The pre-1969 version of § 128217 did not contain an express prohibition against remarriage during a specified period. However, it did provide that a divorce decree did not become absolute and effective until six months after the date it *759was rendered. Two years after first inserting language in § 1280 providing that only those marriages contracted outside Oklahoma were unlawful, the Legislature again amended the statute. The only change made to § 1280 by this amendment deleted language providing that divorce cases were to have priority before this Court.18

Before the Legislature amended § 1280, its meaning had been judicially determined in Hess, Branson, Mantz, and Mudd — marriages contracted outside of Oklahoma and occurring within the prohibitory period had to continue beyond the six-month period to ripen into valid common law marriages.19 When the Legislature amends a statute whose meaning has been settled by case law, it has expressed its intent to alter the law.20 The Legislative intent to change the law is expressed in the 1969 amendment of § 1280 prohibiting only those marriages contracted within Oklahoma.

CONCLUSION

The express language of 12 O.S.1981 § 128021 prohibits remarriage only if it occurs within Oklahoma during the six months following a divorce. Nothing in the language of the statute indicates that the same prohibition is to be imposed upon marriages contracted outside of Oklahoma. We may not, through judicial fiat, impose a restriction upon marital rights not intended by the Legislature.22 A marriage conducted in another state during the six-month prohibitory period against remarriage contained in § 1280 is valid.

with whom HODGES, Vice Chief Justice, joins, concurring in result.

Whether valid, void or merely voidable at its inception, these parties’ out-of-state ceremonial marriage is a fit subject for judicial dissolution. The trial court was hence clearly in error when it refused to entertain the divorce suit. It is solely for this reason that I concur in today’s result. Whitney v. Whitney, 192 Okl. 174, 134 P.2d 357, 360 (1943); Whitney v. Whitney, 194 Okl. 361, 151 P.2d 583, 585 (1944); Krauter v. Krauter, 79 Okl. 30, 190 P. 1088, 1090 (1920).
