First, in New York Supreme Court and Family Court Orders that provide for Child Support or Maintenance (Alimony) can only be modified by the Court. In some instances they can be modified only an agreement signed and acknowledged by the parties and notarized. A verbal agreement is insufficient.
Second, Child Support can only be modified from the date that one petitions the Court to modify support based on a change in circumstances. Meaning if you file a petition to modify a support order you will still be liable for support that accrued prior to the petition.
Third, a party can bring the other party to Family Court for Child Support owed. If he does, Support Magistrates hear the case and do not consider verbal agreements as a defense to non payment.
If there is no order whatsoever and there is no written agreement that requires a party to pay Child Support and Maintenance then the party seeking support/maintenance can only obtain Child Support and Maintenance as of the date of the Petition.
In either event, you should consult an attorney and bring any of the following documents that exist including a Judgment of Divorce, Separation Agreement (or Settlement Agreement) Family Court Orders etc.
