Petition to Modify Custody and Support

What the Petition to Modify Custody and Support Is

A Petition to Modify Custody and Support is a court filing seeking a legal change to an existing child custody order or child support obligation. It asks the family court to revise parenting time, legal custody, physical custody, or the amount and terms of child support based on changed circumstances, best-interest factors, or mistake in the original order. The petition typically cites the prior decree, explains why modification is warranted, identifies the relief requested, and attaches supporting declarations and financial information for the judge to review.

Why This Petition Matters

Modifying custody or support updates legal responsibilities to reflect material changes — protecting the child’s best interests and ensuring support amounts are accurate given current incomes and circumstances.

Common Mistakes to Avoid When Preparing the Petition
