Petitioner (hereinafter the father) and respondent (hereinafter the mother) are the parents of a son (born in 2008). The parties lived together with the child in the City of Binghamton, Broome County until the summer of 2008. The father then moved to the City of Norwich, Chenango County. Upon the parties’ consent, Family Court issued an order in March 2009 awarding joint legal custody, primary residence to the mother and visitation to the father on alternate weekends. In May 2009, the father commenced this proceeding seeking a modification of custody. Following a hearing, the court continued joint legal custody, but granted primary residence to the father and visitation to the mother three weekends per month, with the father responsible for transportation. The parties cross-appeal.
The mother contends that Family Court erred by not analyzing this as a relocation case under Matter of Tropea v Tropea (87 NY2d 727, 740-741 [1996]). As the mother did not raise this argument in Family Court, it is unpreserved for our review.
Treating this as a typical modification case, Family Court should have dismissed the petition. The party seeking modification of a custody order must first prove that there has been a sufficient change in circumstances since the entry of the prior order to require the court to reexamine the issue of custody (see Matter of Rosi v Moon, 84 AD3d 1445, 1445-1446 [2011]; Matter of Opalka v Skinner, 81 AD3d 1005, 1005 [2011]). A best interest analysis should only be undertaken after this threshold showing has been made (see Matter of Fox v Grivas, 81 AD3d 1014, 1015 [2011]; Matter of Chase v Benjamin, 44 AD3d 1130, 1131 [2007]).
Here, Family Court deemed unsubstantiated the father’s allegations that the child suffered injuries in the mother’s care, that her home was unsafe and unsanitary, that she did not properly administer the child’s medication and that the child’s
