APPEAL from the Circuit Court of Cook County; the Hon. CHARLES
J. FLECK, Judge, presiding.
MR. JUSTICE WILSON DELIVERED THE OPINION OF THE COURT:
Ferdinand E. Kowalski, plaintiff, appeals from a trial court order which denied his request to terminate alimony to his former wife, Lorraine, (defendant). The order abated alimony for the period from November 1973 to January 1977, and defendant cross-appeals from this portion of the order. The issues presented for review are (1) whether or not defendant's conduct came within the purview of the Illinois Marriage and Dissolution of Marriage Act (Ill. Rev. Stat. 1977, ch. 40, pars. 510(b), 801) (Marriage Act); (2) whether or not the trial court erred in failing to terminate alimony; and (3) whether or not the trial court erred in abating alimony for the period of cohabitation. We affirm in part, reverse in part and remand with directions. The pertinent facts follow.
A decree of divorce by default in favor of Ferdinand was originally entered on October 21, 1969, which provided for a waiver of alimony by Lorraine. Lorraine filed a petition to vacate the decree in March 1971, and an order was entered on this in October 1972. The parties were finally divorced on May 6, 1974, and Lorraine was awarded $100 per week in permanent alimony.
On July 13, 1979, Ferdinand filed an amended motion to terminate alimony, alleging among other things that:
"From approximately October, 1975 to and including March, 1978, the Defendant and Counterplaintiff resided and cohabitated with Ray Landeck on a resident, continuing conjugal basis."
Lorraine testified that she had lived with Landeck as his common law wife for a period of three years from November 1973 to December 1976. At the conclusion of the hearing, the trial court denied the motion to terminate alimony but abated the amount owed for the period of cohabitation which it determined to be from November 1973 to January 1977. The court reasoned that during the time of defendant's cohabitation, she was a ward of the court, and this may be considered a factor in its determination.
The first issue to be considered is the application of the Marriage Act, which became effective October 1, 1977, to defendant's conduct. Both parties acknowledge that defendant's incompetency has no effect on the proceedings involved here. Ferdinand argues that the statute provides in pertinent part as follows:
(a) This Act applies to all proceedings commenced on or after its effective date.
(b) This Act applies to all pending actions and proceedings commenced prior to its effective date with respect to issues on which a judgment has not been entered * * *.
(c) This Act applies to all proceedings commenced after its effective date for the modification of a judgment or order entered prior to the effective date of this Act." (Ill. Rev. Stat. 1977, ch. 40, par. 801.)
As such, any proceedings commenced subsequent to the effective date of the Marriage Act to modify alimony or maintenance are governed by its provisions. We do not quarrel with this contention that the Marriage Act governs the proceedings insofar as the petition for modification was filed in July 1979. However, we are asked to consider the conduct of defendant as a basis for termination under section 510(b) *fn1 of the Marriage Act.
Plaintiff relies on Lamp v. Lamp (1979), 73 Ill. App.3d 713, 392 N.E.2d 349, and In re Custody of Ehr (1979), 77 Ill. App.3d 540, 396 N.E.2d 87, as support for his argument that the Marriage Act governs defendant's conduct in this instance. This reliance is misplaced. In both Lamp and Ehr, we stated that the Marriage Act governed petitions for modifications filed on or after October 1, 1977, but in each of these instances we looked at the conduct or condition in issue only as it was present at the time of the petition. In Lamp, defendant was awarded possession of the marital home during the minority of the parties' children, which would be sold upon the youngest child attaining the age of 18 years or her remarriage. Plaintiff obtained custody of the children by agreement in February 1977 and in October 1978 filed a petition for modification, seeking an immediate sale of the parties' marital home. The trial court held that defendant's possessory interest in the home could be viewed as periodic alimony, a provision for child support or a combination thereof. It considered the transfer of custody a change of circumstances and concluded that the home ...
