Section 545 - Order of support by parents1. In a proceeding in which the court has made an order of filiation, the court shall direct the parent or parents possessed of sufficient means or able to earn such means to pay weekly or at other fixed periods a fair and reasonable sum according to their respective means as the court may determine and apportion for such child's support and education, until the child is twenty-one. The order shall be effective as of the earlier of the date of the application for an order of filiation, or, if the children for whom support is sought are in receipt of public assistance, the date for which their eligibility for public assistance was effective. Any retroactive amount of child support shall be support arrears/past-due support and shall be paid in one sum or periodic sums as the court shall direct, taking into account any amount of temporary support which has been paid. In addition, such retroactive child support shall be enforceable in any manner provided by law including, but not limited to, an execution for support enforcement pursuant to subdivision (b) of section fifty-two hundred forty-one of the civil practice law and rules. The court shall direct such parent to make his or her residence known at all times should he or she move from the address last known to the court by reporting such change to the support collection unit designated by the appropriate social services district. The order shall contain the social security numbers of the named parents. The order may also direct each parent to pay an amount as the court may determine and apportion for the support of the child prior to the making of the order of filiation, and may direct each parent to pay an amount as the court may determine and apportion for the funeral expenses if the child has died. The necessary expenses incurred by or for the mother in connection with her confinement and recovery and such expenses in connection with the pregnancy of the mother shall be deemed cash medical support, and the court shall determine the obligation of either or both parents to contribute to the cost thereof pursuant to subparagraph five of paragraph (c) of subdivision one of section four hundred thirteen of this act. In addition, the court shall make provisions for health insurance benefits in accordance with the requirements of section four hundred sixteen of this act.2. The court, in its discretion, taking into consideration the means of the father and his ability to pay and the needs of the child, may direct the payment of a reasonable sum or periodic sums to the mother as reimbursement for the needs of the child accruing from the date of the birth of the child to the date of the application for an order of filiation.N.Y.
