A UCCJEA affidavit is a sworn statement you file with your custody paperwork that tells the judge where your child has lived for the past five years, who the child lived with, and whether any other court case involves the child. Every state except Massachusetts requires one, and in most courts your custody case will not move forward until it is on file. The requirements come from Section 209 of the Uniform Child Custody Jurisdiction and Enforcement Act, a model law adopted to keep a single court in charge of each child’s custody dispute and to stop parents from moving children across state lines to shop for a friendlier judge.
What Has to Be in the Affidavit
Section 209 sets out exactly what every party must disclose, under oath, in their first pleading or an attached affidavit. The categories are:
- The child’s current address.
- Every place the child has lived during the past five years, with the dates of each residence and the names and current addresses of every adult who lived with the child during each period.
- Whether you have participated, in any capacity, in any other proceeding involving custody of or visitation with the child. If so, you have to identify the court, the case number, and any determination made.
- Whether you know of any proceeding that could affect the current case, including domestic violence protective orders, child protective investigations, termination of parental rights, or adoptions, with the court, case number, and nature of each.
- Whether anyone who is not a party to the current case has physical custody of the child or claims custody or visitation rights, along with their names and addresses. This covers grandparents, stepparents, or other relatives who may hold rights from a separate case.
The statute says this information is required “if reasonably ascertainable.” That gives you some room when, for example, you genuinely cannot track down a former roommate’s current address. It is not a license to leave sections blank. A judge who sees gaps can order you to supplement the affidavit or answer questions under oath about what is missing.
Start the address history with where the child lives now and work backward. Each entry needs exact dates and the full names of the adults in the household during that period. If a parent, stepparent, or grandparent shared the home for part of a stretch, list that person for that stretch, not the whole range.
Signing the Affidavit
Most courts publish a standardized form through the clerk’s office or the court website. The layout varies, but every version tracks the Section 209 list.
Because the affidavit is sworn, you have to sign it in a way that carries legal consequences for dishonesty. Some states require a notary public to witness your signature. Others let you sign under penalty of perjury without a notary. Check your court’s form for which method applies. If notarization is required, bring a government-issued photo ID to the notary appointment. Notary fees for a single signature are modest, often under $10, though they vary by state.
Filing and Serving the Affidavit
The affidavit goes in with your initial custody paperwork. If you are starting the case, it is filed with your petition. If you are responding, it goes in with your answer. Courts accept filings in person, by mail, and in many places through electronic filing portals. You pay the standard filing fee for the overall case when you submit your documents; the amount varies by court.
After filing, you have to serve a copy of the affidavit on the other parent and on anyone else with a legal interest in the child. Service is normally handled by a process server or a sheriff’s deputy, who provides a proof-of-service document that you then file with the court. This step is not optional. If the other party does not receive the affidavit along with the rest of the petition, the judge may refuse to proceed until service is properly completed.
If Disclosing Your Address Would Be Unsafe
You do not have to hand your address to the other parent if doing so would put you or the child at risk. Section 209(e) of the UCCJEA says that when a party alleges under oath that disclosure of identifying information would jeopardize the health, safety, or liberty of a party or child, the court must seal that information. It stays hidden from the other party and the public unless the judge holds a hearing, weighs the safety concerns, and specifically finds that disclosure serves the interest of justice.
This matters most in cases involving domestic violence. Many states also run Address Confidentiality Programs that assign participants a substitute mailing address, which you can typically use for court filings and service of process. Enrollment in one of those programs does not change the custody or visitation order itself. If you are in a dangerous situation, raise the safety concern with the court before filing your affidavit, or include the allegation of risk inside the affidavit so the sealing provision applies from the start.
What Happens If You Skip It or Lie
Skipping the affidavit is not just a paperwork problem. Under Section 209(b), when the required information is not furnished, the court may stay the entire proceeding until it is. Your case sits frozen, temporary orders do not get issued, and hearings do not get scheduled. Many judges will not enter a final custody determination at all without the affidavit on file. If you are the one who needs a custody order, that delay cuts against you. File the affidavit as soon as possible so the case can move.
Lying on the affidavit carries real consequences. Providing false information is perjury. At the federal level, perjury carries a prison sentence of up to five years. State penalties vary but are universally treated as serious criminal offenses. Beyond the criminal exposure, a judge who catches false statements in the affidavit will view everything else you say with suspicion, which is damaging in a case decided on credibility and the child’s best interests.
Your Duty to Update
Filing the affidavit is not a one-time task. Section 209(d) imposes a continuing duty on every party to inform the court if a new proceeding is filed in any state that could affect the current case. If the other parent files for custody in a different state while your case is pending, or if a child protective investigation opens somewhere, notify your court promptly. Failing to do so can undermine your credibility and may lead the judge to question whether you are trying to manipulate the jurisdictional process.
The statute’s continuing duty is written around new proceedings, but many courts also expect you to update the affidavit if the child moves to a new address while the case is pending. A move can change which state qualifies as the home state, and judges need current information to keep jurisdiction straight.
Why the Address History Matters: Home State Jurisdiction
The reason the affidavit asks for five years of addresses is that custody jurisdiction turns on where the child has actually lived. Under the UCCJEA, a child’s “home state” is wherever the child lived with a parent for at least six consecutive months immediately before the case was filed. For a baby younger than six months, the home state is wherever the child has lived since birth. Short absences, such as a two-week vacation, count toward the six-month period rather than breaking it.
Home state status is the strongest basis for jurisdiction. If your child has lived in a state for at least six months before you file, that state’s court has jurisdiction and no other state can override it. Even if the child recently left, the former home state keeps jurisdiction for six months as long as one parent still lives there.
When no state qualifies as the home state, the UCCJEA provides fallback options. A court in a state where the child and at least one parent have a “significant connection” and where substantial evidence about the child’s life exists can take the case, but only if no home state exists or the home state has declined to act. If no state meets even that standard, any state with a connection to the child can step in. These backup categories exist for families who move frequently and never hit the six-month mark in one place, including military families and families experiencing homelessness.
The information you put in the affidavit is what lets the judge work through this hierarchy. An accurate five-year address history makes it obvious whether the six-month threshold is met and whether another state has a stronger claim. The affidavit also surfaces any other open cases, so if a judge sees that a court in another state already has a case involving the same child, the two courts are required to communicate and decide which one should proceed. This cross-state coordination is reinforced by the federal Parental Kidnapping Prevention Act, which requires every state to respect custody determinations made by a court with proper jurisdiction.
That is why the affidavit is treated as foundational rather than procedural. Everything the judge decides about where your case belongs, and later about any modification, rests on the facts you put in it.
