In this case we address procedural issues regarding a pre-1988, unmerged marital settlement agreement (MSA) and the proper mode of enforcement for such an agreement. We find the proceedings in the instant case severally flawed, and vacate the order entered by the triаl court.
The facts and procedural history are as follows. Lisle and Lowell were divorced in Wyoming County on August 9, 1984. They had no children. Prior to the divorce, the parties entered a Marital Settlement Agreement (MSA) which provided for distribution of their property and payment of alimony to Lisle. The agreement was signed on March 5, 1984. Lowell failed to make the agreed upon monthly payments beginning August 1985. Lisle then filed a civil contempt petition against Lowell in Wyoming County on July 13, 1989. In response Lowell brought a petition under the Pennsylvania Divorce Code attacking the validity of the Marital Settlement Agreement. The Wyoming County Common Pleas Court treated Lowell’s petition as a petition for modification of a support order. Pursuant to the Divorce Code, 23 P.S. § 507, the trial court denied Lisle any further alimony effective January 1, 1988. Lisle then brought this timely appeal.
Lowell and Lisle enterеd into a MSA on March 5, 1984 in anticipation of their subsequent divorce. The decree of *522 divorce entered August 9, 1984 incorporated the MSA but did not mentiоn merger. The issue of merger at this juncture was integral to the parties future rights under the MSA and the Divorce Code in existence at that time and, ultimately, to their rights under the Divorce Code as amended in 1988.
In Pennsylvania, a settlement agreement between a husband and wife is governed by the law of contrаcts unless the agreement itself provides otherwise.
Caccavo v. Caccavo,
Our review of the MSA revealed its language to be clear and unambiguous in unequivоcally evincing the parties intent that the “agreement shall survive an action for divorce and decree of divorce and shall
forever
be binding and conclusive on the parties” and
“no modification
or waiver of any of the terms hereof shall be valid
unless in writing and signed by both parties”
(emphasis added) (MSA items 3, 13). Lowell and Lisle’s MSA, by its own terms, was a contract separate and independent of the divorce decree and enforcеable under assumpsit and equity principles rather than under the Divorce Code until 1988. The 1988 Amendment to the Divorce Code allows
enforcement but not modification
of an unmerged MSA under the Code.

23 P.S. § 401.1(b) and (c).
Cf. DeMatteis v. DeMatteis,
We find no anomoly in аpplying the enforcement procedures provided by the 1988 Amendment to a pre-1988 MSA while refusing to apply other provisions of the Amendment whiсh would involve a change in obligations of the parties. The language of the parties’ MSA specifically provided for a modification рrocedure but did not specify a particular *523 manner of enforcement. Prior to the 1988 Amendments there was no provision for enforcement of nonmodifiable, unmerged MSA’s under the Divorce Code, and so an action in assumpsit was used as in any other contract action. The 1988 Amendment does not preclude a complaint in assumpsit; it merely facilitates enforcement of the MSA by providing an alternative enforcement vehicle in the form of civil contempt complaint. The amendment neither adds to nor subtracts from the substantive rights of the parties under their MSA; rather, it merely provides an additional procedural vehicle for the enforcement of their respective rights under their MSA.
Originally, when Lowell stopрed making payments as required by the MSA, Lisle properly brought a complaint in assumpsit to enforce the contract with Lowell. We do not have the records or even the docket entries from the assumpsit action, which was brought in Lackawanna County. Assuming, arguendo, Lisle’s complaint filed in Wyoming County is an аccurate report of the proceedings in Lackawanna County, default judgment was entered against Lowell when he failed to respond to the complaint filed against him pursuant to Pa.R.C.P. 1037. We will assume that entry of judgment in Lackawanna County was procedurally correct. Assuming Lowell fаiled to comply with the directive of the Lackawanna County court further enforcement action could then have been pursued by Lisle in Lаckawanna County. Lisle, however, did not elect to pursue the Lackawanna County judgment further.
Lisle instead brought a complaint in civil contemрt against Lowell in Wyoming County pursuant to the powers of enforcement provided in Section 401(b) of the Divorce Code effective February 12, 1988. Under Section 401.1(a), enforcement of a non-merged MSA under the provisions of the Code is permitted “to the same extent as though the agreemеnt had been an order of the court except as provided to the contrary in the agreement." There is no contrary provision in their MSA; accordingly, the original MSA between Lowell and Lisle which specifically provided for *524 modification only by written agreement between the parties could be enforced but not modified under the provisions of the Divorce Code.
Lowell’s response to the civil contempt complaint was to attack the validity of the original MSA under Section 401 of thе Divorce Code by seeking invalidation of the agreement and/or termination of his alimony obligation. The issue of the validity of the MSA, however, was decided finally when it was originally incorporated in the divorce decree. Because no appeal asserting fraud or mistake in the еxecution of the MSA was taken from the divorce decree, the MSA must be deemed to be valid, and the validity of the MSA must be deemed finally determined fоr purposes of any further proceeding.
Sonder, supra,
378 Pa.Superior Ct. 481-483,
Consequently, the Wyoming County court erred when it treated Lowell’s response to Lisle’s complaint аs a petition for modification of a support order. As explained supra, there was no support order in existence; there was only a contract between Lisle and Lowell subject to either judgment and execution as a contract, or special enforcement authorized under the 1988 amendments to the Divorce Code.
The terms of the contract provide for cessation of the agreed upon alimony only on Lisle’s “remarriage.” The trial court stopped Lisle’s support because she was “cohabiting” with a man. That dеtermination, however, necessarily entailed an impermissible
modification
of the terms of the original MSA. Had Lowell wanted to stop paying alimony if Lisle began to “cohabitate” with another man, that could have been made part of the original MSA. We do not find the term “remarriage” sufficiently ambiguous to embrace “cohabitation”, standing by itself. There must be, at the least, evidence of cohabitation
and
reputation of marriage to give risе to the presumption that a common law marriage has been entered into.
Canute v. Canute,
Conclusion
Based on the foregoing, the Wyoming County order is Vacated. The casе is remanded to Wyoming County for action on Lisle’s petition for civil contempt and enforcement of the MSA as written in accordance with the Divorce Code. Jurisdiction is relinquished.
