Child Support Modification Petition in New York

Federal & State Law Editorial TeamLast reviewed: April 2026

Start with the official New York form

The canonical, court-accepted version of this form is published by the Family Court in the county of either parent or Supreme Court (if part of divorce). Search your county or district court's website for the current Child Support Modification Petition form before relying on any template.
