The alleged breach of confidential or fiduciary duty occurred almost a year after the death of Plaintiff's decedent. Accordingly, Plaintiff's causes of action did not yet exist in decedent's favor as of his death ( cf., EPTL 11-3.2 [b]), and Plaintiff's cannot press a cause of action that was not viable during decedent's life ( see, Sweets v Behrens, 88 AD2d 745, 746). We have considered Plaintiff's remaining arguments in support of their standing to sue and find them to be without merit. Since the complaint was properly dismissed, we do not reach Plaintiff's alternate contention.
