Summary judgment cannot be granted solely on the basis of the defendant father-in-law's denial of having orally promised to support plaintiff and her children. Such denial serves only to raise an issue of credibility. Moreover, it is at variance with a long history of support. Defendants' assertion of the statute of frauds as a bar to this action is premature prior to discovery. Defendants' own records may contain a writing sufficient to satisfy the statute. Nor can it be determined at this stage whether the statute is rendered inapplicable by partial performance.

Given the absence of prejudice since the claim arises out of the same set of facts originally alleged, leave to amend the complaint to include a claim of equitable estoppel was properly granted. Defendants were or should have been alerted to the claim from the outset ( see, Edenwald Contr. Co. v. City of New York, 60 N.Y.2d 957, 959; Schrader v. Carney, 180 A.D.2d 200, 208).
