IN RE: ANTHONY L. (2021)

Order, Family Court, New York County (Jane Pearl, J.), entered on or about January 30, 2020, which, to the extent appealed from as limited by the briefs, upheld the report of the Support Magistrate, dated July 25, 2019, finding that respondent/ petitioner mother substantiated her reasonable childcare expenses, and declining to credit petitioner/respondent father for asserted overpayments for the child's health insurance premiums predating the filing of his petition for a downward modification, unanimously affirmed, without costs.  Appeal from order, same court and Judge, entered on or about January 2, 2020, unanimously dismissed, without costs, as subsumed in the appeal from the order entered on or about January 30, 2020.

Great deference should be given to the findings of the Support Magistrate, who was in the best position to assess the evidence presented and the credibility of the witnesses (see Matter of Minerva R. v. Jorge L.A., 59 A.D.3d 243, 875 N.Y.S.2d 446 [1st Dept. 2009]).  Here, the Support Magistrate found the mother's testimony about her job search, freelance work, and attempts to obtain vocational training, while parenting a special needs child, to be credible (see Family Ct Act § 413[1][c][4], [6]).  Her award of reasonable childcare costs, reflecting the time available to her to seek employment and training while the child was in school is supported by the record, and there is no reason to disturb it.

Contrary to the father's contention, the law of the case doctrine generally does not apply to evidentiary rulings on retrial (People v. Evans, 94 N.Y.2d 499, 504, 706 N.Y.S.2d 678, 727 N.E.2d 1232 [2000]).  It was a provident exercise of discretion for the Support Magistrate to assess the documentary evidence provided by the mother in light of the mother's credible testimony about payments to the childcare workers, as well as that of a corroborating neighbor (see Matter of Schiero v. Perrotta, 140 A.D.3d 970, 971, 32 N.Y.S.3d 656 [2d Dept. 2016]).

The father contends that he should be awarded credit for overpayments of his portion of the child's health insurance, retroactive to the time at which the mother's cost to insure the child purportedly dropped, rather than to the date he filed his petition for a downward modification.  However, modification of a child support order is effective only to the date of the filing of the modification petition, in this case, January 9, 2012 (see Family Ct Act § 449;  Sonmez v. Sonmez, 121 A.D.2d 883, 503 N.Y.S.2d 574 [1st Dept. 1986]).

We have considered the father's remaining contentions and find them unavailing.
