Ordered that the order dated June 3, 2011, is affirmed, without costs or disbursements.
“Modification of an existing custody arrangement is permissible only upon a showing that there has been a change in circumstances such that modification is necessary to ensure the best interests of the child” (Matter of Strand-O’Shea v O’Shea, 32 AD3d 398, 398 [2006]; see Matter of Fitje v Fitje, 87 AD3d 599, 600 [2011]; Matter of Deochand v Deochand, 80 AD3d 609, 610 [2011]; Matter of Mazurkiewicz v Pindor-Mazurkiewicz, 80 AD3d 615, 616 [2011]). “A party seeking such a modification is not automatically entitled to a hearing on the application, but first must make an evidentiary showing sufficient to warrant a hearing” (Matter of Fitje v Fitje, 87 AD3d at 600; see Matter of Deochand v Deochand, 80 AD3d at 610; Matter of Mazzola v Lee, 76 AD3d 531 [2010]; Matter of Grassi v Grassi, 28 AD3d 482 [2006]; Matter of Carpenter v Whitaker, 5 AD3d 681 [2004]). Here, the conclusory, unsubstantiated, and nonspecific allegations set forth in the paternal grandmother’s petition failed to meet this standard, and the Family Court properly dismissed the petition without a hearing (see Matter of Fitje v Fitje, 87 AD3d at 600; Matter of Deochand v Deochand, 80 AD3d at 610; Matter of Grant v Hunter, 64 AD3d 779 [2009]; Matter of Blackstock v Price, 51 AD3d 914, 915 [2008]).
