ORDERED that the decree is affirmed, with costs payable by the appellants personally.
The appellants, with counsel present, entered into a stipulation in open court settling both this probate proceeding (Matter No. 1) and declaratory judgment action (Matter No. 2). They later moved to vacate the stipulation on the ground, inter alia, that their attorney for the declaratory judgment action was absent.
Stipulations of settlement, especially those made in open court, are favored by the courts and not lightly cast aside (see, Hallock v. State of New York, 64 N.Y.2d 224, 230; Burkart v. Burkart, 182 A.D.2d 798). "[O]nly where there is cause sufficient to invalidate a contract, such as fraud, collusion, mistake or accident, will a party be relieved from the consequences of a stipulation made during litigation" (Hallock v. State of New York, supra, at 230; Matter of Frutiger, 29 N.Y.2d 143, 149-150). The appellants failed to demonstrate that the stipulation of settlement should be vacated on the ground that it contains a material mistake.
The record reflects that the appellants, without voicing any objection, entered into the stipulation utilizing an attorney cloaked with apparent authority to represent them in both the probate proceeding and the declaratory judgment action (see, Hallock v. State of New York, supra, at 231; Ford v. Unity Hosp., 32 N.Y.2d 464, 473). Thus, the appellants' claim that the stipulation should be vacated because it was entered into in the absence of their attorney for the declaratory judgment action is unpersuasive.
The appellants' remaining contentions are without merit.
