Ordered that the order is affirmed insofar as appealed from, without costs or disbursements.
In an action pursuant to RPAPL 1501 to determine claims to real property, the plaintiffs bear the burden of proof to establish title ( see, Town of N. Hempstead v. Bonner, 77 A.D.2d 567). The plaintiffs' are obligated to affirmatively prove that they hold legal title to the property, which is not satisfied merely by pointing to weaknesses in the defendants' title ( see, Town of N. Hempstead v. Bonner, supra, at 568).
At bar, the plaintiffs conclusively established their claim of title to the subject property. The defendants failed to demonstrate the existence of triable issues of fact with respect to the plaintiffs' claim of title and thus the Supreme Court's grant of summary judgment in favor of the plaintiff's was appropriate ( see, Zuckerman v. City of New York, 49 N.Y.2d 557, 560).
In addition, the Supreme Court properly continued the third-party action. The fact that a plaintiff has moved for summary judgment on the complaint does not authorize the Supreme Court to search the record in the third-party action and to grant summary judgment pursuant to CPLR 3212 (b) in that action ( see, Dunham v. Hilco Constr. Co., 89 N.Y.2d 425; Mercedes-Benz Credit Corp. v. Dintino, 198 A.D.2d 901, 902; Sutton v. Cobb, 50 A.D.2d 995, 996).
The parties' remaining contentions are without merit.
