Ordered that the appeal from so much of the order of commitment as committed the father to the custody of the Nassau County Correctional Facility for 30 days is dismissed as academic, without costs or disbursements, as the period of incarceration has expired; and it is further,
Ordered that the order of commitment is affirmed insofar as reviewed, without costs or disbursements.
The Family Court correctly confirmed the Support Magistrate's finding, made after a hearing, that the father willfully violated the court's prior support order. The finding is entitled to great deference on appeal ( see Matter of Stone v. Stone, 236 AD2d 615), and prima facie evidence of willfulness was established by the father's failure to comply with the support order. The father failed to rebut this evidence by offering sufficient proof of his inability to pay ( see Family Ct Act § 454 [a]; Matter of Powers v. Powers, 86 NY2d 63, 69-70; Matter of Stone v. Stone, supra).
The father's remaining contentions are without merit.
