Child Support

Laws current as of August 8, 2025

How long does child support last?

A parent’s legal responsibility to pay child support usually ends when their child becomes “emancipated.” Your child becomes emancipated when they do any one of these things:

  • turn 21;
  • get married;
  • join the military and serve full-time; or
  • get convicted of a felony and sentenced to two or more years in prison.1

The judge may also decide that child support payments will end if your child does any of these things:

  • turns 18, stops going to school full-time, and does not have a disability;
  • chooses to move out of their custodial parent or guardian’s home, lives independently, works full-time, and stops pursuing their education;
  • lives with another person without the approval of the parent who pays support;2 or
  • is incarcerated but not emancipated. Note: Child support payments will stop while a child is incarcerated, but they may start again once the child is released.3

If a parent is behind on their child support payments, emancipation does not end their obligation. A parent who already owes back child support (arrears) from before the child became emancipated is still responsible for paying the full amount they owe.4
