    David Eshaghian, Appellant, v Mahrokh Eshaghian et al., Respondents, et al., Nominal Defendant.
    [43 NYS3d 902]
   Order, Supreme Court, New York County (Eileen Bransten, J.), entered on or about June 13, 2016, which, among other things, denied plaintiff’s motion for summary judgment, and granted defendants-respondents’ cross motion for summary judgment on their counterclaims and for sanctions against plaintiff, unanimously affirmed, without costs.

Supreme Court correctly determined that plaintiff’s action is barred by the doctrine of res judicata (see Landau, P.C. v LaRossa, Mitchell & Ross, 11 NY3d 8, 12 [2008]), because he is essentially seeking to relitigate the validity of a side agreement that was at issue and decided in a Surrogate’s Court proceeding. The side agreement and the parties’ letter agreement are intertwined and part of the same real estate transaction (see Wietschner v Dimon, 139 AD3d 461, 461 [1st Dept 2016], Iv denied 28 NY3d 901 [2016]). By the terms of the letter agreement, defendants, as the prevailing parties in the Surrogate’s Court proceeding, are entitled to their reasonable attorneys’ fees and costs incurred in that proceeding. The sanctions imposed by the motion court were appropriate (22 NYCRR 130-1.1 [a]).

We have considered the parties’ remaining arguments, including defendants’ request for sanctions for this appeal, and find them unavailing.
