Matter of Garber

— In a probate proceeding in which the executor of the estate, Thomas D. Garber, petitioned to judicially settle his account, the petitioner appeals from an order of the Surrogate’s Court, Suffolk County (Czygier, Jr., S.), entered November 9, 2016, which denied his motion to vacate a stipulation of settlement. Ordered that the order is affirmed, with costs payable by the appellant personally. To vacate the subject stipulation of settlement on the ground of mutual mistake, the appellant was required “to demonstrate that the mistake existed at the time the stipulation was entered into and that it was so substantial that the stipulation failed to represent a true meeting of the parties’ minds” {Mahon v New York City Health & Hosps. Corp., 303 AD2d 725, 725 [200.3]; see Matter of Steger, 81 AD3d 737, 738 [2011]; Radish Pharm. v Blue Cross & Blue Shield of Greater N.Y., 114 AD2d 439 [1985]). On this record, the appellant failed to meet his burden (see George Backer Mgt. Corp. v Acme Quilting Co., 46 NY2d 211, 219 [1978]; Yakohowicz v Yakobowicz, 142 AD3d 996 [2016]; Matter of Steger, 81 AD3d at 738). The appellant’s remaining contentions are without merit. Accordingly, the Surrogate’s Court properly denied the appellant’s motion to vacate the stipulation. Balkin, J.P., Austin, Sgroi and LaSalle, JJ., concur.
