If you’ve just been served, here is how to respond to custody papers: find the deadline printed on the summons, file a written answer with the court clerk before that date addressing every paragraph of the petition, and include a counterclaim if you want the court to order something different from what the other parent asked for. Most jurisdictions give you 20 to 30 days. Miss the window and the judge can grant what the other parent requested without hearing from you at all.
Find Your Deadline First
The single most important number in the paperwork is the response deadline. Depending on your state and how you were served, you typically have somewhere between 20 and 30 days to file a written response. The clock usually starts the day the papers are handed to you or left at your home. The exact date should appear on the summons. If it doesn’t, call the court clerk’s office the same day and confirm.
Missing the deadline lets the other parent ask for a default judgment. That means the judge may grant everything the petition requested, including custody arrangements and support obligations, without ever hearing from you. Getting a default set aside is possible but difficult. Courts generally require you to show a legitimate reason for the failure, such as improper service, excusable neglect, or fraud. Even then, you’re fighting uphill, and the process takes time your children don’t have. Treat the deadline like it is carved in stone.
Read What the Petition Is Actually Asking For
Custody papers go by different names depending on where you live. You might see “petition,” “complaint,” or “summons.” They all open a legal case about who makes decisions for your children and where the children live. Your written response has to address each request in the petition, so you need to understand what those requests mean.
- Legal custody is the right to make major decisions about your child’s life, including education, healthcare, and religious upbringing. Joint legal custody means both parents share that authority. Sole legal custody means one parent decides alone.
- Physical custody is where the child actually lives day to day. Joint physical custody means the child splits time between both homes, though not always equally. Sole physical custody means the child lives primarily with one parent while the other typically gets a visitation schedule.
A petition might request sole legal and physical custody, joint custody with a specific parenting schedule, or some combination. Read every paragraph. The papers may also contain allegations about your parenting, your living situation, or specific incidents. Those claims matter because they frame the story the court hears first if you stay silent.
Write Your Answer and, If You Want Something Different, a Counterclaim
Your written response usually has two parts, and the difference between them matters.
The answer is where you go through the petition paragraph by paragraph and state whether you agree, disagree, or lack enough information to respond. This is not the place to tell your full story. It is a technical document. If a paragraph says you and the other parent separated on June 1 and the actual date was May 15, you deny that paragraph and state the correct date. If a paragraph accurately lists the children’s names and ages, you admit it. Skipping paragraphs or giving vague responses can be treated as admissions.
The counterclaim, sometimes called a counter-petition, is where you tell the court what you want. If you are satisfied with everything the other parent requested, you may not need one, though even then it is wise to put your agreement in writing so the other parent cannot change course later. If you want a different custody arrangement, a specific visitation schedule, or child support from the other parent, the counterclaim is where you ask for it. Filing one does not make you look combative. It protects your right to have the court consider your preferred outcome.
File It, Then Serve the Other Parent
Once your answer and any counterclaim are complete, file them with the court clerk. Most courts accept filings in person, by mail, or through an electronic filing system. There is usually a filing fee, though it tends to be modest. If you cannot afford the fee, you can ask the court for a fee waiver. Qualification typically requires showing that your income falls below a certain threshold or that you receive public benefits like food assistance or Medicaid. The court clerk’s office can provide the waiver form.
After filing, you must serve the other parent with a copy of your response. You cannot hand-deliver it yourself. In most jurisdictions, anyone over 18 who is not a party to the case can serve the papers, whether that is a friend, a relative, or a professional process server. The person who delivers the documents then completes an affidavit of service, a short sworn statement describing what was delivered, when, and to whom. That affidavit gets filed with the court as proof the other side received your response. Without proof of service on file, the court may treat your response as if it was never filed.
Confirm the Case Was Filed in the Right State
Before you accept the case on its merits, make sure the court has jurisdiction. Under the Uniform Child Custody Jurisdiction and Enforcement Act, adopted in all 50 states, the child’s “home state” generally has jurisdiction over custody proceedings. The home state is the state where the child lived with a parent for at least six consecutive months immediately before the case was filed.1Office of Justice Programs. The Uniform Child-Custody Jurisdiction and Enforcement Act For an infant younger than six months, the home state is wherever the child has lived since birth. Temporary absences, like a vacation, still count toward the six-month period.
If you and the other parent live in different states, jurisdiction can become complicated. The home-state rule usually controls, but exceptions exist when no state qualifies as the home state or when emergency circumstances threaten the child’s safety. If you believe the case was filed in the wrong state, raise that issue immediately in your response. A court that lacks jurisdiction cannot make a valid custody order, and challenging jurisdiction is one of the strongest early defenses available.
Gather Your Documents While the Clock Runs
Building a response takes preparation. Start collecting the following as soon as you are served:
- Children’s records: birth certificates, Social Security numbers, school enrollment documents, and medical records.
- Financial documents: recent pay stubs, tax returns, bank statements, and records of debts and assets. Most courts require both parents to exchange detailed financial disclosures early in the case, and having these ready prevents delays.2Administration for Children and Families. What Documents Do I Need to Bring to the Child Support Office
- Living arrangement details: your current address, the size and layout of your home, the child’s sleeping arrangements, and proximity to schools or childcare.
- Relevant history: dates of any prior custody agreements, significant changes in either parent’s circumstances, and documentation of your involvement in the child’s daily life, such as school pickup records, medical appointment logs, or communications with teachers.
If the petition contains allegations you dispute, gather evidence that contradicts them now while details are fresh. Text messages, emails, photos, and witness contact information are all harder to recover later. Keep everything organized in a folder, physical or digital, that you can hand to an attorney or reference when completing court forms.
Watch for a Temporary Orders Hearing
In many cases, the petitioner asks for temporary orders at the same time they file the custody petition. Temporary orders set the rules for custody, visitation, and sometimes support while the case is pending, which can take months. A hearing on temporary orders can be scheduled much sooner than your answer deadline, sometimes within days if the petition alleges an emergency. Check the papers carefully for any mention of a temporary order hearing date. If one is scheduled, showing up prepared for that hearing matters as much as filing your written response.
Temporary orders are not final, but they carry real weight. Judges sometimes use the status quo established by a temporary order as a starting point for the permanent arrangement, particularly if the children have adjusted well. Letting a temporary order go unchallenged can shape the rest of the case.
What Not to Do While the Case Is Pending
The period between being served and your first court date is when people do the most damage to their own cases. Judges evaluate your behavior during the entire proceeding, not just at trial.
- Do not ignore the papers. Hoping the case will go away guarantees a default judgment. Even if you believe the filing is unfair or retaliatory, the court treats silence as surrender.
- Do not badmouth the other parent to your children. Courts take parental alienation seriously. Criticizing the other parent in front of the kids, or through them, signals to a judge that you may not support the child’s relationship with both parents.
- Do not vent on social media. Anything you post can be screenshotted and entered as evidence. Angry rants about your ex, photos of late-night outings, and even casual complaints about the legal process have all been used against parents in custody hearings.
- Do not withhold the children. Unless a court order or a genuine safety emergency says otherwise, keeping the children from the other parent looks like you’re trying to gain leverage. In some jurisdictions, taking children out of the area without notice can trigger emergency orders against you.
- Do not violate existing orders. If there is already a temporary order or prior agreement about custody, support, or visitation, follow it to the letter. Contempt of court findings can lead to fines or jail time and will color the judge’s view of your fitness as a parent.
Act like a judge is watching, because eventually one will review everything you did during this period.
If You Cannot Afford an Attorney
Hiring a family law attorney is the single best thing you can do for your case, but it is not always financially realistic. If you need to represent yourself, you still have options. Most courthouses have a self-help center or family law facilitator who can help you identify the correct forms, explain filing procedures, and review your documents for obvious errors. These staff members cannot give legal advice, but they can keep you from making procedural mistakes that get your response thrown out.
Legal aid organizations in your area may offer free or reduced-cost representation in custody cases, particularly when domestic violence is involved or income is very low. Many local bar associations also run lawyer referral programs with low-cost initial consultations, enough to get your questions answered even if you handle the rest yourself. If full representation is out of reach, some attorneys offer “unbundled” or limited-scope services where they handle specific tasks, like drafting your answer or preparing you for a hearing, at a fraction of the cost of full representation.
