IN RE: Pernetha G. OATES (2007)

In a child custody proceeding pursuant to Family Court Act article 6, the mother appeals from an order of the Family Court, Dutchess County (Amodeo, J.), entered March 3, 2006, which, after a hearing, awarded sole custody of the subject child to the father.

ORDERED that the order is affirmed, without costs or disbursements.

 The essential consideration in making an award of custody is the best interests of the child (see Eschbach v. Eschbach, 56 N.Y.2d 167, 171, 451 N.Y.S.2d 658, 436 N.E.2d 1260;  Friederwitzer v. Friederwitzer, 55 N.Y.2d 89, 95, 447 N.Y.S.2d 893, 432 N.E.2d 765;  Miller v. Pipia, 297 A.D.2d 362, 364, 746 N.Y.S.2d 729).   A custody determination is largely based upon the hearing court's assessment of the credibility of the witnesses and of the character, temperament, and sincerity of the parties (see Schneider v. Schneider, 40 A.D.3d 956, 836 N.Y.S.2d 301;  Matter of Brian S. v. Stephanie P., 34 A.D.3d 685, 686, 825 N.Y.S.2d 232).   Thus, “[w]here a hearing court has conducted a complete evidentiary hearing, its finding must be accorded great weight, and its grant of custody will not be disturbed unless it lacks a sound and substantial basis in the record” (Matter of Brian S. v. Stephanie P., 34 A.D.3d at 686, 825 N.Y.S.2d 232;  see Miller v. Pipia, 297 A.D.2d at 364, 746 N.Y.S.2d 729;  Young v. Young, 212 A.D.2d 114, 117, 628 N.Y.S.2d 957).

 Here, the Family Court properly considered numerous factors in making its custody determination.   The Family Court's determination that the best interests of the subject child would be served by awarding sole custody to the father was supported by a sound and substantial basis in the record and should not be disturbed (see Eschbach v. Eschbach, 56 N.Y.2d at 174, 451 N.Y.S.2d 658, 436 N.E.2d 1260;  Matter of Timosa v. Chase, 21 A.D.3d 1115, 803 N.Y.S.2d 575).
