What Documents Do You Need for a Custody Case

Start with what you already have

If you are in a custody dispute, you probably have more documentation than you realize. Court orders in your email. Text messages on your phone. Report cards in a drawer. Medical records in a patient portal. The challenge is not that you lack documents. It is knowing which ones matter and getting them all in one place.

According to Clio's 2026 family law statistics, 72% of family law cases involve at least one self-represented parent. If that is you, gathering the right documents is even more critical because you do not have an attorney doing it for you.

This checklist covers everything you should try to collect. You will not have every single item, and that is okay. Gather what you can. Something organized is always better than nothing.

Court filings and legal documents

These are the foundation of your case. If any filings exist, you need copies.

Current custody order (if one exists). This is the baseline the court will measure changes against.
Temporary orders. Any interim orders issued while the case is pending.
Parenting plan (proposed or current). The schedule, decision-making rights, holiday arrangements.
Declarations and motions filed by either side. These contain the claims each party is making.
Mediation agreements (if applicable). Any prior agreements, even informal ones.
Protective orders or restraining orders (if applicable).

If you do not have copies of your own filings, you can request them from the court clerk's office. Most courts also have online portals where you can download case documents.

Communication records

Communication between co-parents is often the most telling documentation in a custody case. LegalMatch lists communication records as one of the top five types of documentation to gather.

Text messages. Screenshot important exchanges with dates visible. See our guide to organizing text messages for how to do this properly.
Emails. Print to PDF or save as files. Include the full header showing sender, recipient, date, and subject.
Co-parenting app records. If you use OurFamilyWizard, TalkingParents, or a similar app, export your communication logs.
Voicemail recordings or transcripts. If relevant, save audio files and transcribe the content with dates.
Social media posts. If the other parent has posted anything relevant to the case (contradicting claims, inappropriate content, location check-ins that conflict with their schedule), screenshot it with the date visible.

Financial documents

Financial stability is one factor courts consider. Even if your case is not primarily about money, having these ready shows preparation.

Tax returns (last 2-3 years).
Pay stubs (recent, showing current income).
Bank statements (if relevant to support issues or shared expenses).
Child support payment records. Proof of payments made or missed.
Receipts for child-related expenses. Medical co-pays, school fees, extracurricular costs, clothing. Especially important if you are seeking reimbursement or demonstrating that the other parent is not contributing.
Childcare costs. Daycare invoices, after-school program fees, babysitter payments.

Children's records

These documents paint a picture of your child's daily life and wellbeing, and show your involvement as a parent.

School records. Report cards, attendance records, teacher communications, IEP or 504 plans if applicable. According to CustodyXChange, school records help demonstrate which parent is actively involved in the child's education.
Medical records. Doctor's visit summaries, vaccination records, prescription histories, therapy or counseling records. These show that your child is receiving proper care.
Therapy or counseling records. If the child is in therapy, notes from the therapist (with appropriate consent) can be relevant.
Extracurricular activity records. Registration forms, schedules, coach or instructor communications. Shows involvement and stability.

Documentation of concerns

If you have safety concerns or specific issues you need the court to address, document them.

Police reports. Any calls to law enforcement related to the children or the other parent.
CPS reports. If Child Protective Services has been involved, request copies of any reports or findings.
Photos. Anything that documents a concern: living conditions, injuries, unsafe situations. Include dates and context.
Witness information. Names and contact information for people who have firsthand knowledge of relevant events (teachers, neighbors, family members, therapists). You may not need formal statements right away, but having the list ready matters.
A custody journal. A running log of relevant events, missed visits, communication issues, and your child's behavior. See our guide to keeping a custody journal.

What you probably do not need

Just as important as knowing what to gather is knowing what to leave out. Courts have limited time and attention. Including irrelevant documents can actually hurt your credibility.

The rule of thumb from Alimentor's documentation guide: "Stick to Facts: Write what happened, when, where, and who was present. Avoid insults, diagnoses, or assumptions about motives." If a document or note contains insults or assumptions about why the other parent did something, it weakens everything around it.

Every text message ever sent. Only include messages that directly relate to a specific claim.
Character reference letters from friends and family. These carry very little weight unless the person has direct knowledge of specific events.
Your personal narrative. A 15-page account of your relationship history is not a document. Your declarations and organized claims cover this.
Documents about the other parent's personal life that do not affect the children. A judge does not care about who they are dating unless it directly impacts the kids.

Where to find documents you do not have

Some of these documents may not be in your possession. Here is where to look:

Before we get to the list, one important note: when you file documents with the court, the California Courts Self-Help Guidewarns to "black out private information, like Social Security numbers." This applies in most jurisdictions. Redact sensitive personal information before anything gets filed publicly.

Court filings: Court clerk's office or your county's online case portal.
Medical records: Your child's doctor's office or patient portal. You have the right to request these as a parent.
School records: Contact the school directly. The U.S. Department of Education confirms that "unless a school is provided with evidence that there is a court order, state law, or other legally binding document relating to such matters as divorce, separation, or custody that specifically provides to the contrary, FERPA gives custodial and noncustodial parents alike certain rights with respect to their children's education records."
Financial records: Your bank's online portal, your employer's payroll system, or the IRS (for tax transcripts).
Police reports: The local police department where the report was filed. There may be a small fee for copies.

Once you have everything

Gathering is step one. Organizing is step two. A pile of documents is not a case; it is just a pile.

When I went through my own custody case, I had documents scattered across three email accounts, two phones, a filing cabinet, and a shared Google Drive. I knew I had the right paperwork somewhere. Finding it and connecting it to the right claims was the hard part.

That is why I built Casefold. You upload your documents, and AI reads them and organizes the claims by party and category. Each claim links back to the exact passage in the source document. You and your attorney (if you have one) see the same organized view.

But even without any tool, the process is the same. Use this checklist. Gather what you can. Then organize it by category and by claim, not by date. Our guide to organizing custody documents walks through that step by step.

You do not need every item on this list to have a strong case. You just need the ones that matter, organized so someone else can understand them.
