Matter of Samuel O.M. v. Patricia Mari Daniella B.

Order, Family Court, New York County (Clark V. Richardson, J.), entered on or about December 11, 2015, which denied petitioner’s motion for genetic testing and dismissed the paternity petitions, unanimously affirmed, without costs. *549 The Family Court properly found that it was in the children’s best interests to equitably estop petitioner from claiming paternity (Family Ct Act § 532 [a]). Petitioner waited nearly four years after the birth of the older child before commencing this proceeding, and failed to communicate with the children or provide financial support (see Matter of Cecil R. v Rachel A., 102 AD3d 545 [1st Dept 2013]; Matter of David G. v Maribel G., 93 AD3d 526 [1st Dept 2012]). Petitioner also indicated that he did not wish to assume a parental role in the children’s lives, and declined to interfere with their adoptions. Meanwhile, the children have formed attachments with their adoptive parents, with whom they have lived for most of their lives. Given the need to “prevent unwanted intrusion by the child’s former biological relatives to promote the stability of the new adoptive family” (Matter of Elido B. v Jennie C., 55 AD3d 1008, 1009 [3d Dept 2008] [internal quotation marks omitted]), dismissal of the petitions was appropriate. Concur—Acosta, J.P., Andrias, Moskowitz, Gische and Webber, JJ.
