Ordered that the order is affirmed, without costs or disbursements.
There is no merit to the mother’s contention that the Court Attorney Referee lacked authority to hear and determine the petition, since the record demonstrates that the parties executed a stipulation consenting to such a reference (see CPLR 4317 [a]; Matter of Phelps v Hunter, 101 AD3d 1689 [2012]; cf. Matter of McClarin v Valera, 108 AD3d 719 [2013]; Matter of Stewart v Mosley, 85 AD3d 931, 932 [2011]).
“When determining custody cases, the primary concern is the best interests of the child” (Salvatore v Salvatore, 68 AD3d 966, 966 [2009] [internal quotation marks omitted]; see Eschbach v Eschbach, 56 NY2d 167, 171 [1982]; Matter of Edwards v Rothschild, 60 AD3d 675, 676 [2009]). The factors to be considered in determining the custody arrangement that is in the child’s best interests include “the quality of the home environment and the parental guidance the custodial parent provides for the child, the ability of each parent to provide for the child’s emotional and intellectual development, the financial status and ability of each parent to provide for the child, the relative fitness of the respective parents, and the effect an award of custody to one parent might have on the child’s relationship with the other parent” (Matter of Miguel R. v Maria N., 104 AD3d 771, 772 [2013]; see Eschbach v Eschbach, 56 NY2d at 171-173; Matter of Mullins v Riener, 100 AD3d 760, 761 [2012]). “As custody determinations turn in large part on assessments of the credibility, character, temperament, and sincerity of the parties, the Family Court’s determination should not be disturbed unless it lacks a sound and substantial basis in the record” (Matter of Khan-Soleil v Rashad, 111 AD3d 728, 729 [2013] [internal quotation marks omitted]; see Eschbach v Eschbach, 56 NY2d at 173; Matter of Cornejo v Salas, 110 AD3d 1068 [2013]).
Contrary to the mother’s contention, the Family Court’s determination that it was in the child’s best interests to award sole custody to the father has a sound and substantial basis in the record. Accordingly, we decline to disturb it (see Matter of McKoy v Vatter, 106 AD3d 1090 [2013]; Matter of Guzman v Pizarro, 102 AD3d 964, 965 [2013]).
The mother’s remaining contentions are either unpreserved for appellate review or without merit.
