Ordered that the order is affirmed insofar as appealed from, with costs.
Contrary to the determination of the Supreme Court, whether the defendants failed to exercise that degree of care, skill, and diligence commonly possessed by a member of the legal community ( see Dimond v. Kazmierczuk McGrath, 15 AD3d 526) inter alia, in failing to appraise certain marital property in this case, was not decided or necessarily determined in any prior proceeding. Accordingly, the Supreme Court incorrectly concluded that the plaintiff was collaterally estopped from arguing that the defendants committed legal malpractice ( see Weiss v. Manfredi, 83 NY2d 974; Katash v. Richard Kranis, P.C., 229 AD2d 305). Nevertheless, the Supreme Court correctly granted the defendants' motion for summary judgment dismissing the complaint. The defendants made a prima facie showing of entitlement to judgment as a matter of law by demonstrating that they either did not commit legal malpractice or that any alleged malpractice was not a proximate cause of the plaintiff's alleged damages ( see Alvarez v. Prospect Hosp., 68 NY2d 320; Wexler v. Shea Gould, 211 AD2d 450). With respect to the plaintiff's allegation that the defendants failed to obtain an appraisal of certain marital property, with the result that she received less than her fair share of its value, the defendants demonstrated prima facie that the property was gifted to the parties' son at an agreed-upon value. Thus, an appraisal was unnecessary. In opposition, the plaintiff failed to raise a triable issue of fact.
Accordingly, the Supreme Court correctly granted the defendants' motion for summary judgment dismissing the complaint.
The plaintiff's remaining contentions are without merit.
