Section 523. Petition

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.
