How to File for Custody in Oklahoma: Step-by-Step Process

Filing for custody in Oklahoma follows a structured legal process with specific documents, deadlines, and filing requirements. Whether you are filing as part of a divorce or as an unmarried parent seeking a custody order, the steps are essentially the same — and missing any of them can delay your case by weeks or months.

Step 1: Confirm Residency and Jurisdiction

Before filing, you must meet Oklahoma's residency requirement. The petitioner or respondent must have been an actual, good-faith resident of Oklahoma for at least six months immediately before filing. Additionally, the case must be filed in the county where the filing parent has resided for at least 30 days, or in the respondent's county of residence.

Oklahoma must also be the child's "home state" under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA) — meaning the child has lived in Oklahoma for at least six consecutive months before the filing.

Step 2: Prepare Your Filing Documents

You need three core documents to initiate a custody action:

Petition for Dissolution of Marriage (if married) or Petition for Paternity and Custody (if unmarried). This is the formal pleading that asks the court to determine custody and parenting time.

Summons. The official court document notifying the other parent that a case has been filed against them.

UCCJEA Affidavit. A jurisdictional requirement detailing where the child has lived for the past five years, which confirms Oklahoma has authority over the custody case. Every custody case requires this affidavit — it is not optional.

Oklahoma courts provide standard blank forms through the Oklahoma State Courts Network (OSCN). Court clerks can hand you the forms but are legally barred from telling you what to write in them.

Step 3: Pay Filing Fees

Filing fees vary by county and are due when you submit your petition:

If you cannot afford the filing fee, you can request a waiver by submitting Form 13.3 (Pauper's Affidavit). Under Local District Court Rule 21, the clerk places you on an uncontested docket where you present financial documentation (SNAP, TANF, or SSI benefit records). If the judge approves, the filing and summons fees are waived. Note: attorneys cannot submit a Pauper's Affidavit on behalf of a client.

Step 4: Serve the Other Parent

After filing, you must formally serve the other parent with the petition and summons. Service can be performed by:

• A private process server
• A deputy sheriff
• Certified mail with a return receipt

The 24-hour waiver rule. If the case is uncontested and the other parent wants to waive formal service, they can sign an Entry of Appearance and Waiver — but they must not sign it until at least 24 hours after the petition has been filed with the court clerk. A waiver signed before the 24-hour mark is legally void, and the court cannot enter a final decree on the papers.

Once served, the respondent has 20 days to file a written Answer.

Step 5: Automatic Temporary Injunction

Upon filing and service, an Automatic Temporary Injunction (ATI) immediately takes effect under 43 O.S. § 110. This court order freezes assets, prohibits insurance changes, and prevents either parent from removing children from their current school or taking them out of state for more than two weeks without written consent.

Step 6: File for Temporary Orders (If Needed)

If custody, visitation, or child support arrangements cannot wait for the final hearing, either parent can file an Application for Temporary Order. The other parent must receive at least five days notice of the temporary order hearing. The court must hold this hearing within 30 days if domestic abuse is not alleged.

Step 7: Complete Parenting Education

Both parents must complete an approved parenting class under 43 O.S. § 107.2 before the court will enter a final custody order. File your certificate of completion with the court clerk.

What Comes Next

After filing, service, and any temporary orders, you enter the 90-day waiting period (for cases involving minor children). During this time, both parents should be drafting and negotiating a detailed parenting plan. If you reach agreement, the court can enter a final decree incorporating your plan. If not, the case proceeds to trial.
