A declaration for family court is a written statement of facts, signed under penalty of perjury, that a judge reads in place of live testimony when deciding a custody, visitation, or support motion. To write one that holds up, you need the right caption and format, numbered paragraphs of firsthand facts, exhibits that back up what you say, redactions where the rules require them, and a correctly worded signature block. The sections below walk through each piece in the order you’ll actually draft them.
Format and Caption
Every declaration starts with a caption at the top of the first page. The caption identifies your case and includes the full name of the court, the names of both parties, and the case number. Below the caption, title the document plainly: “Declaration of [Your Full Name] in Support of [Motion Type].”
Formatting requirements vary by court, but most family courts expect the same basics: 8.5-by-11-inch paper, a readable font like Times New Roman or Arial in 12-point, double-spaced lines, and sequential page numbers at the bottom. Many courts also impose page limits — often around 10 pages for an initial declaration and 5 pages for a reply. Going over the limit without permission is the kind of avoidable error judges notice.
Before you draft anything from scratch, check your court’s self-help website or clerk’s office for a pre-printed or fillable declaration form. If one exists, use it. The court’s own form eliminates most formatting guesswork and signals that you read the local rules.
Writing the Body
Number each paragraph separately. This lets the judge, the other party, and any attorneys reference specific points without confusion. Organize the information either chronologically or by topic, grouping related facts under headings like “Pickup and Drop-Off Issues” or “Medical Decision Disagreements.” For complex situations, topical organization usually reads more clearly than a straight timeline.
The most important skill in declaration writing is showing the judge what happened rather than telling them what to conclude. “The other parent is irresponsible” is an opinion the judge will ignore. “On March 15, 2025, the other parent was 45 minutes late picking up our child from school and did not call me or the school to explain the delay” is a fact the judge can weigh. Specific dates, times, and locations turn vague complaints into credible evidence. If you don’t remember the exact date, say so. “In approximately mid-March 2025” is honest and still useful.
Every statement must come from your own firsthand knowledge: something you personally saw, heard, or experienced. Judges insist on this because secondhand information — what someone else told you they saw — is generally inadmissible hearsay. There are narrow exceptions. Statements the other parent made directly to you, for instance, are not hearsay because they come from a party to the case. As a general rule, though, stick to what you witnessed yourself. If your neighbor saw something important, the neighbor should write their own declaration.
What to Leave Out
Declarations that try to do too much end up doing nothing well. A few categories of content consistently hurt more than they help.
- Opinions and name-calling. Characterizing the other parent as “narcissistic,” “manipulative,” or “unfit” wastes your limited page count. State the behavior and let the court draw its own conclusions.
- Legal arguments. Your declaration is for facts. Arguments about what the law requires or how the court should interpret a statute belong in a separate brief or points-and-authorities filing. Mixing legal argument into a factual declaration muddies both.
- Irrelevant history. A declaration about school pickup disputes doesn’t need three paragraphs about why the marriage ended. Stay focused on the specific issue before the court.
- Hearsay. Don’t include what other people told you. “My sister said she saw the other parent drinking at the park” will likely be disregarded. Your sister needs to submit her own declaration.
The temptation to include everything is understandable. The stakes are high and you want to be heard. But judges read dozens of declarations, and a tight statement with five strong factual points is far more persuasive than a rambling document that buries those same points in 15 pages of grievances.
Attaching Exhibits
Exhibits are the documents that back up what you’ve written: screenshots of text messages, emails, photographs, school records, medical records, receipts, police reports. A factual claim supported by a document is more credible than the same claim standing alone.
Reference each exhibit at the point in your declaration where it becomes relevant. For example: “On December 5, 2024, the other parent agreed to the proposed holiday schedule by email. A true and correct copy of this email is attached as Exhibit A.” Label the first page of the attached document “Exhibit A,” and continue sequentially (Exhibit B, Exhibit C) for additional documents. Attach all labeled exhibits to the back of your declaration in order.
For audio or video evidence, many courts require you to provide a written transcript along with the recording. You can prepare the transcript yourself; it doesn’t need to be professionally certified. The other party must receive a copy of both the transcript and the recording before the hearing. Check your court’s rules on electronic evidence, as some courts have specific procedures for digital files.
One common mistake is attaching 50 pages of text messages when three pages would make the point. Judges don’t have time to hunt through screenshots for the relevant exchange. Highlight or mark the specific messages you’re referencing, and cut the rest.
Redacting Sensitive Information
Before you file anything, review every page of your declaration and exhibits for sensitive personal information that needs to be blacked out. Federal courts require that filings include only the last four digits of Social Security numbers and financial account numbers, only the birth year (not full date) for dates of birth, and only initials for minor children’s names.1Legal Information Institute. Federal Rules of Civil Procedure Rule 5.2 – Privacy Protection for Filings Made With the Court Most state family courts follow similar rules.
This is easy to overlook with exhibits. A bank statement you attach as Exhibit C might display your full account number. A medical record might show your child’s full date of birth and Social Security number. Go through every attached document with a black marker for paper filings, or redaction software for electronic filings, before you submit anything. Filing unredacted personal information can result in the court ordering you to re-file corrected versions, and in some cases, sanctions.
Signing Under Penalty of Perjury
The last section of your declaration is the signature block, and it’s what gives the document its legal force. You must include a statement that you are signing under penalty of perjury. For declarations signed within the United States, the standard language is: “I declare under penalty of perjury that the foregoing is true and correct. Executed on [date].” Follow this with your signature, your printed name, and the date. Federal law gives a declaration signed this way the same legal weight as a sworn, notarized affidavit.2Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury A few jurisdictions still require notarized affidavits for certain filings, so check your local court rules before you assume a declaration will be accepted.
The perjury statement is not a formality. If you knowingly include false information in a signed declaration, you can be charged with perjury, a federal crime punishable by up to five years in prison.3Office of the Law Revision Counsel. 18 USC 1621 – Perjury Generally Beyond criminal exposure, a judge who catches false statements will question everything else you’ve submitted. Courts have modified custody and visitation arrangements based on findings that a parent lied in sworn filings.
An unsigned declaration, or one missing the perjury language, will not be considered by the court. Proofread the entire document before signing. Double-check every date, name, and factual detail. Once you’ve signed, you own every word.
Supporting Declarations From Other People
You’re not limited to your own declaration. Friends, family members, teachers, therapists, or anyone else with relevant firsthand knowledge can write and sign their own declarations supporting your position. A neighbor who regularly sees your child’s living conditions, a teacher who can speak to your involvement in school activities, or a friend who witnessed a concerning incident can each submit one.
Third-party declarations follow the same rules: numbered paragraphs, firsthand knowledge only, signed under penalty of perjury. The person writing should explain at the beginning who they are, how they know the parties, and why they have relevant information. Keep supporting declarations focused and short. A two-page statement from a credible witness who saw something specific is worth more than a five-page character reference full of generalities.
Filing and Serving the Declaration
Filing means submitting your declaration to the court so it becomes part of the official record. Many courts offer electronic filing portals where you upload directly. If your court doesn’t have e-filing, or you prefer paper, you can file in person at the clerk’s office. Filing fees for motions vary widely by jurisdiction, from nothing in some courts to several hundred dollars in others. If you can’t afford the fee, ask the clerk’s office about a fee waiver.
After filing, you must serve a copy on the other party or their attorney. You cannot serve the documents yourself. Service must be performed by someone at least 18 years old who is not a party to the case.4Legal Information Institute. Federal Rules of Civil Procedure Rule 4 – Summons Common methods include having a friend or family member hand-deliver the documents, hiring a professional process server, or mailing copies via certified mail. Some jurisdictions also allow electronic service if the other party has agreed to receive documents that way.
After service, the person who delivered the documents fills out a Proof of Service form documenting when, where, and how the documents were delivered. File that form with the court. Without a filed Proof of Service, the court may treat your declaration as if the other side never received it, which can delay your hearing or cause your motion to be denied.
Responding to the Other Side’s Declaration
If the other parent files a motion with a supporting declaration, you’ll typically need to file a responsive declaration before the hearing. The deadline varies by jurisdiction but is commonly set at a specific number of court days before the hearing, often somewhere between five and nine court days. Missing this deadline can mean the judge decides the motion based solely on what the other side submitted.
A responsive declaration follows the same formatting and signing rules as an initial one. Focus on the specific claims the other party made. If they stated something inaccurate, lay out the facts that contradict it. If they omitted important context, supply it. Attach exhibits that support your version. In many courts, the party who filed the original motion can then file a short reply declaration addressing only what you raised, not introducing new issues. Address everything that matters in your first response, because you may not get another chance to write before the hearing.
