Being handed custody papers, whether at your door, at work or in the mail, can knock the wind out of you. If you're searching for how to respond to custody papers, you've already done the most important thing: you're taking it seriously instead of setting the envelope aside. The next few days matter, and most of what you need to do is simpler than it feels right now.

This guide walks you through the first 72 hours, explains what each document in the packet usually means, covers how response deadlines and written responses generally work, and lists the mistakes that can quietly damage your position before you ever see a judge.

What should you do in the first 72 hours?

Read everything, find your deadlines, and protect the status quo. Don't respond to the other parent in anger, and don't make big decisions about the child yet.

  1. Write down when and how you were served. The date often starts the clock on your deadline. Note who handed you the papers, or the date on the mail receipt.
  2. Read every page, twice. Including the small print on the summons and any notice of hearing.
  3. Find every date. Your response deadline, any hearing date, and any deadline for mediation or a parenting class. Put them all on one calendar.
  4. Check for an order already in effect. Some packets include a temporary or emergency order that applies immediately. If there is one, follow it exactly.
  5. Make copies and start a folder. Keep the originals clean and unmarked. Write your notes on a copy.
  6. Find help. Locate your court's self-help center, and look into legal aid or a consultation. See free and low-cost legal help for custody cases.
  7. Write down your side while it's fresh. For each claim in the petition, jot down what you believe is accurate, what isn't, and what records might show it.

What are all these documents in a custody packet?

Custody packets often include several documents, and each one does something different. Here's what the common ones usually mean.

DocumentWhat it usually isWhat to look for
SummonsOfficial notice that a case was filed against youYour response deadline and how to respond
Petition or complaintThe other parent's request and the reasons they giveExactly what they're asking for, paragraph by paragraph
Notice of hearingA scheduled court dateDate, time, courtroom or video link
Motion for temporary ordersA request for orders while the case is pendingWhat changes they want now, and when it will be heard
Temporary or emergency orderAn order already signed by a judgeWhat it requires starting now and when the follow-up hearing is
Proposed parenting planTheir suggested schedule and decision-makingSchedule, holidays, exchanges, decision-making
Financial affidavitIncome and expense information, often for supportWhether you must file your own

If the packet includes a protective order, that's a separate process with its own rules and usually a faster hearing. See served with a protective order? how to respond the right way.

How long do you have to respond to custody papers?

The deadline is set by your state's rules and is usually printed on the summons or notice. Find it, count it carefully, and file before it, not on it.

A few things catch people off guard:

  • The hearing can come before the response deadline. A motion for temporary orders may be heard in days or weeks, regardless of when your written response is due. Prepare for both.
  • Counting rules vary. Some deadlines count calendar days, some count business days, and the way weekends and holidays are handled differs. If you're unsure, ask the clerk.
  • Filed means received by the court. In many courts, mailing your response on the last day isn't enough. Check how and when your filing counts as filed.
  • The method of service can matter. In some places, being served by mail adds a few days to the deadline. Don't assume; confirm.

How do you write a response to a custody petition?

Use your court's response form if it has one. Many response forms let you agree or disagree with each part of the petition, and some let you state what you're asking for. The names vary: answer, response, counter-petition or counterclaim.

Many responses follow the petition's numbered paragraphs. You go through each one and state whether you admit it, deny it, or don't have enough information to admit or deny it. Here's how that format often looks:

Example format (check your court's form)

Paragraph 3: Admit. The child has attended [school name] since [month and year].

Paragraph 4: Deny. The child has lived with both parents on an alternating weekly schedule since [month and year].

Paragraph 5: Without enough information to admit or deny the statements about [topic], and therefore denied.

If you have your own requests, like a different schedule or decision-making arrangement, ask the self-help center how to include them. Some courts handle that within the response; others require a separate counter-petition. You may also need a proposed parenting plan; see how to write a parenting plan that works.

Keep the tone factual. Your response is often the first thing the judge reads from you. Correct inaccuracies with specifics and dates, and leave out insults, sarcasm and speculation about the other parent's motives.

What if you agree with most of it?

Agreeing doesn't mean you can skip responding. If you don't file anything, the court may not know you agree, and you may lose the chance to correct the parts that are wrong. Many courts have a way for parents to submit a written agreement, sometimes called a consent order or stipulation, that a judge can review and sign. If you and the other parent are close on most issues, mediation can be a good place to work out the rest. Just read any agreement carefully before signing, because once a judge approves it, it becomes an enforceable order, and changing it later generally means going back to court.

What should you avoid after being served?

Some of the most damaging mistakes happen in the first few weeks, before any hearing.

  • Ignoring the papers. The case can move forward without you.
  • Changing the child's routine on your own. Withholding the child, moving, or changing schools without agreement or a court order can be held against you.
  • Firing off angry messages. Anything you text or post can end up as an exhibit. Before you hit send, it can help to step away or try checking a message's tone before you send it.
  • Talking to your child about the case. Children shouldn't carry adult conflict or be asked to choose.
  • Posting about the case online. Even private accounts and group posts can be shared.
  • Signing an agreement you don't understand. It's reasonable to take time to read an agreement and get advice before signing.
  • Deleting messages or posts. Once a case is pending, parties are generally expected to preserve relevant evidence.

How do you prepare for the first hearing?

The first hearing is often short and often about temporary arrangements, so focus on your child's current routine and your most important concerns. See what happens at the first custody hearing for what usually takes place. Gather these before the hearing:

  • The papers you were served, your filed response, and file-stamped copies.
  • A calendar showing who has actually cared for the child over the past few months.
  • School, child care and medical information.
  • Key messages with the other parent, exported and printed, not just on your phone.
  • A one-page outline of what you're asking for and why, in two or three minutes of speaking.

A tool like Case Builder can put the hearing date countdown, your timeline and the key exhibits in one place, so you're working from a single organized file instead of a stack of loose papers. If the case raises complicated issues, like a move to another state or serious allegations, a consultation with a licensed attorney where you live before the hearing can be well worth the time.
