Before GOODWIN, WALLACE and FARRIS, Circuit Judges.

*1345FARRIS, Circuit Judge:

San Pedro Fishermen’s Welfare Trust Fund Local 33 brought this action to enforce payment of trust fund contributions pursuant to a collective bargaining agreement. The district court granted the Trust Fund’s motion for summary judgment and denied its motion for attorney’s fees. We affirm the granting of summary judgment but the 1980 amendments to ERISA § 502(g), 29 U.S.C. § 1132(g) (1976), require a reversal of the denial of attorney’s fees. We remand to the district court for a proper determination of attorney’s fees.

I. *Facts*

San Pedro Fishermen’s Welfare Trust Fund Local 33 is a third party beneficiary of a collective bargaining agreement (master agreement) between Di Bernardo et al. (employers) and Fishermen & Allied Workers’ Union, Local 33. The master agreement was modified by a 1978 strike settlement agreement. The issue presented is whether employers must make health and welfare benefit contributions for striking employees. The written terms of the agreements are not in dispute. The parties dispute the interpretation of those agreements.

Di Bernardo et al. contend that (1) the master agreement did not require health and welfare benefit contributions for striking employees, and (2) even assuming the master agreement so provided, that it was effectively modified by the strike settlement agreement and by oral statements made during strike negotiations. The trial court held that the master agreement mandated such payments 1 and that subsequent agreements did not alter that obligation.

II. *Summary Judgment*

Section 302(c) of the Labor Management Relations Act, 29 U.S.C. § 186 (1976 & Supp. II 1978), permits employer contributions to welfare trust funds under rigid safeguards. Section 302(c)(5) requires that the detailed basis on which such payments are made be set forth in writing.2 It has been held (1) that oral modifications of a written welfare trust fund agreement specifying payments are invalid and contrary to public policy, *Lewis v. Seanor Coal Co.,*382 F.2d 437, 443-44 (3d Cir. 1967), *cert. denied,*390 U.S. 947, 88 S.Ct. 1035, 19 L.Ed.2d 1137 (1968); and (2) that a written welfare trust fund agreement supersedes prior oral understandings as well as subsequent modifications, *Boyle v. North Atlantic Coal Corp.,*331 F.Supp. 1107, 1108 (W.D.Pa. 1971). The policy behind § 302(c)(5) requires that contract interpretation be confined to the written terms of the welfare trust fund agreement. *See generally Thurber v. Western Confer, of Teamsters Pension Plan,*542 F.2d 1106, 1108 (9th Cir. 1976). Oral statements regarding the meaning of a written trust fund agreement are difficult to prove and judicial recognition of such oral statements may invite collusion and controversy to the detriment of the beneficiaries.

The district court properly entered the summary judgment order as (1) the strike settlement agreement did not alter the master agreement on this subject; and (2) no oral modifications will be recognized.

*1346III. *Attorney’s Fees*

This action, involving a multiemployer plan, was brought under § 502(g) of ERISA, 29 U.S.C. § 1132 (1976). At the time the action was brought the award of attorney’s fees was discretionary. However the 1980 amendments to section 502(g) now make the award of attorney’s fees mandatory in such cases.3 We must apply the law in effect at the time we render our decision. *See Bradley v. School Board of Richmond,*416 U.S. 696, 711-16, 94 S.Ct. 2006, 2016-19, 40 L.Ed.2d 476 (1974).4 Section 502(g)(2), as amended, is applicable and requires that attorney’s fees be awarded. *Central States v. Alco Express Co.,*522 F.Supp. 919 (E.D.Mich.1981). The order denying the Trust Fund’s motion for attorney’s fees is reversed and the case remanded for a determination of the amount of attorney’s fees to be awarded.

Affirmed in part, reversed in part and remanded.
