Modifying and Enforcing Custody and Support Orders
Custody modification
The parent seeking a change must show a change in circumstances that makes modification in the child's best interests. See Child Custody and Parenting Time.
Child support modification
A court may modify an order upon a substantial change in circumstances. It may also do so after three years have passed since the order was entered, last modified or adjusted, or after a change of 15% or more in either party's gross income, unless the parties validly opted out in a written agreement. See Child and Spousal Support.
Maintenance modification
The standard depends on whether the maintenance was set by the court or by the parties' agreement; where an agreement remains in force, modifying maintenance set by that agreement requires a showing of extreme hardship.
Enforcement
Tools include violation petitions, money judgments for arrears, income execution, and other remedies the court may order. Many of these matters are heard in Family Court. See also the FAQ.
