What happens if you don't respond to a custody petition

The Case Can Move Forward Without You

When one parent files a custody petition and has the other parent formally served, the served parent is given a window of time to file a written response with the court. The exact amount of time varies by state, so check your state's guide or the paperwork you were served, which usually states the deadline.

If you never respond, the court does not pause the case to wait for you. In most states, the filing parent can ask the court to proceed by default, which means the judge can make decisions based only on the information the other parent provided. You lose the chance to tell your side of the story.

What a Default Custody Order Can Include

A default order can address the same issues a contested case would, including legal custody, physical custody, the parenting schedule, and often child support. Because the judge only hears from the parent who filed, the resulting orders frequently mirror what that parent requested.

These orders are real, enforceable court orders. Violating them can have serious consequences, and changing a custody order later usually requires you to go back to court and, in many states, show that circumstances have changed. It is almost always harder to undo a default order than it would have been to respond in the first place.

If You Already Missed the Deadline

Missing the response deadline does not always mean the case is over. If a default has not yet been entered, many courts will still accept a late response, so filing quickly can matter a great deal. If a default order has already been entered, most states have a process to ask the court to set it aside, but you generally need a good reason, such as never being properly served, and you must act promptly.

The rules and time limits for setting aside a default vary by state. If you are in this situation, look up your state's process right away rather than waiting, because the longer a default order stands, the harder it usually is to challenge.

Why Responding Is Almost Always the Better Move

Filing a response protects your right to participate. It lets you tell the court what parenting arrangement you believe is best, present your own information, and take part in hearings, mediation, or settlement discussions. Even if you agree with much of what the other parent requested, responding keeps you in the process instead of outside it.

Responding is a document and a deadline, not a courtroom argument, and many self-represented parents handle it successfully. This is general information, not legal advice, and Onbello is not a law firm. For the specific forms and deadlines where you live, check your state's guide.
