Any such petition for the establishment of paternity or the establishment, modification and/or enforcement of a child support obligation for persons not in receipt of family assistance, which contains a request for child support enforcement services completed in a manner as specified in section one hundred eleven-g of the social services law, shall constitute an application for such services.
