Proceedings are commenced by the filing of a verified petition, alleging that the person named as respondent, or the petitioner if the petitioner is a person alleging to be the child's father, is the father of the child and petitioning the court to issue a summons or a warrant, requiring the respondent to show cause why the court should not enter a declaration of paternity, an order of support, and such other and further relief as may be appropriate under the circumstances. The petition shall be in writing and verified by the petitioner. 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.
