The question posed before this court is whether appellant is bound by the terms of the extension clause to pay appellee a six-percent commission. This clause states: “or is sold within three months after the period 0f this listing to anyone with whom you [broker] have negotiated with respect to a sale during the period of -this listing and of whom I have notice, I agree to pay you a commission of 6%***.”
In reviewing this clause, the trial judge found that appellee’s evidence established that appellee had “negotiated” with Y. E. Merillat, and that the farm was sold within three months after the expiration of the August 4th listing. On the issue of whether the clause was supposed to have effect if a sale was made by another broker or only by appellant, the judge found the clause to be ambiguous. We agree with the trial judge when he stated: “***There is a doubt which the broker could have prevented by more explicit phraseology. *413The extension clause simply states ‘or is sold’ but it does not say by whom. More explicit wording would have stated ‘or is sold by me alone or through another broker.’' The ambiguity and doubt is to be resolved against the plaintiff.”3
If the appellee wished to protect itself from the possibility of a sale by another broker, it could have explicitly provided for such an event. Without specific reference to such a possibility, the clause is ambiguous. The age-old maxim of ambiguitas contra stipulatorem est (an ambiguity is resolved against the stipulator) applies to the instant cause. See Franck v. Railway Exp. Agency (1953), 159 Ohio St. 343, 345-346, and O’Neill v. German (1951), 154 Ohio St. 565, 571.
For the foregoing reason, the judgment of the Court of Appeals is reversed.
Judgment reversed.
