Divorce Checklist for Oklahoma

Oklahoma requires that either the petitioner or respondent has been an actual, good-faith resident of the state for at least six consecutive months immediately before filing the divorce petition, as established under Oklahoma Statutes Title 43, Section 102. In addition, the petition must be filed in the county where the petitioner has resided for at least 30 days immediately preceding filing, or in the county where the respondent resides, per Section 43-103. Military personnel stationed at an Oklahoma army post or military reservation for six months satisfy the residency requirement under Section 102(B). You must gather documentation proving your Oklahoma residency, such as a valid Oklahoma driver's license, voter registration card, utility bills, lease agreement, or property tax records showing at least six months of continuous residence. If residency is contested by the opposing party, the court may require additional evidence. Residency is foundational — filing without meeting this threshold will result in dismissal of the case.

Oklahoma recognizes both no-fault and fault-based grounds for divorce under Title 43, Section 101. The most common no-fault ground is incompatibility, which does not require proof of wrongdoing by either spouse. Fault-based grounds include abandonment for one year, adultery, impotency, extreme cruelty, fraudulent contract of the marriage, habitual drunkenness, gross neglect of duty, imprisonment for a felony at the time of filing, and insanity for five years with institutional commitment. Choosing incompatibility is the simplest path — courts generally grant it when either party asserts the marriage is irretrievably broken. However, fault-based grounds can influence property division, spousal support, and custody decisions in contested cases. If you file on incompatibility and have minor children, both parents must complete a mandatory parenting education class under Section 43-107.2. Understanding your grounds before filing shapes the entire trajectory of your case and the evidence you will need to present.

Before filing, compile all personal and financial records that will be required throughout the divorce process. Oklahoma's Automatic Temporary Injunction under Title 43, Section 110 mandates disclosure of specific financial documents once the petition is filed and served — including the past two years of federal and state tax returns, two months of pay stubs from every employer, six months of bank account statements, health insurance coverage documents, childcare expense documentation, and account statements for all debts showing payment terms and most recent balances. Gathering these documents in advance prevents delays and ensures compliance with the ATI's mandatory disclosure timeline. You will also need your original marriage certificate or a certified copy, birth certificates for any minor children, and documentation of all real property, vehicles, retirement accounts, and investment portfolios. Oklahoma follows equitable distribution of marital property, so a complete financial picture is essential for a fair settlement. Missing documents can trigger court sanctions or adverse inferences.

If domestic violence is present in your marriage, your safety planning must begin before you file for divorce. Oklahoma law provides emergency protective orders under Title 22, Section 60.2, which can be obtained without advance notice to the abuser. The Oklahoma Coalition Against Domestic Violence and Sexual Assault (OCADVSA) operates a statewide hotline at 1-800-522-7233 and maintains a shelter directory at ocadvsa.org/resources. Filing a protective order is separate from filing for divorce, but the two proceedings can run concurrently and the protective order can establish temporary custody and exclusive possession of the marital home. Under the Automatic Temporary Injunction statute (§ 43-110), the court can issue an emergency temporary restraining order if irreparable harm would result from waiting for a hearing. DV victims may also qualify for exemption from the mandatory parenting education class under § 43-107.2. Legal Aid Services of Oklahoma at 1-888-534-5243 provides free legal assistance to domestic violence survivors regardless of income level.

The Petition for Dissolution of Marriage is the foundational document that initiates your divorce case in Oklahoma. There are two versions — one for spouses without minor children and one for spouses with minor children. The petition must include both parties' full legal names, the date and place of marriage, a statement of grounds for divorce under Title 43, Section 101, a declaration of residency under Section 102, identification of any minor children with their dates of birth, and your requested relief regarding property division, child custody, child support, and spousal support. You must sign the petition before a notary public, and it must include a Verification page confirming the truth of the allegations under oath. Oklahoma does not use standardized statewide form numbers for divorce petitions — forms are available through Legal Aid Services of Oklahoma at oklaw.org, county court clerks, or the OU Law Library. Complete the petition carefully, as errors may require amendments that cause delays in your case.

Along with your petition, you must prepare a Summons form directing your spouse to respond to the divorce action. The court clerk issues the summons, stamping the original with a red 'Original' designation. Oklahoma law under Title 43, Section 110 requires that an Automatic Temporary Injunction (ATI) Notice accompany the summons. The ATI takes effect upon service and restrains both parties from selling, hiding, or destroying marital assets, changing insurance beneficiaries, removing children from the state without written consent, making extraordinary expenditures without notice, and disrupting children's education or daycare enrollment. The ATI also mandates financial disclosures: both spouses must produce two years of tax returns, two months of pay stubs, six months of bank statements, health insurance documents, childcare expenses, and all debt account statements. Both parties may waive the ATI only by mutual written agreement signed on the ATI notice. Violations of the ATI can result in contempt of court, fines, attorney fee awards, or jail time.

File the original Petition for Dissolution of Marriage, the Summons, and the Domestic Relations Cover Sheet with the district court clerk in the county where you have resided for at least 30 days, per Title 43, Section 103. Filing fees in Oklahoma vary by county — typical costs range from $183 to $268, with Oklahoma County charging approximately $224 and Cleveland County charging approximately $258. The court clerk retains the original petition, stamps your copies with the filing date and case number, and issues the original summons. If you cannot afford the filing fee, you may file an In Forma Pauperis affidavit requesting a fee waiver — the court will evaluate your financial hardship and may waive some or all fees. Oklahoma also offers electronic filing through the Oklahoma State Courts Network at oscn.net/efiling in participating counties. Upon filing, your case receives a case number that you will use on all subsequent documents. The 10-day waiting period for cases without children, or the 90-day waiting period for cases with children, begins running from the filing date.

If your divorce involves children under age 18, Oklahoma requires several additional documents. You must complete a Child Support Computation Form using the Oklahoma Child Support Guidelines under Title 43, Sections 118 through 118I, which calculate support as a percentage of both parents' combined gross income. The computation form is available at oklahoma.gov/okdhs/services/child-support-services/computation.html and must be signed by the judge and attached as an exhibit to the final order. You must also file a Declaration Under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), disclosing the children's addresses for the past five years, any prior custody proceedings, and any persons claiming custody rights. Additionally, prepare a proposed Parenting Plan or Visitation Schedule outlining legal custody, physical custody, holiday schedules, and decision-making authority. Oklahoma uses the best interests of the child standard under Title 43, Section 112 for custody determinations. All child support orders follow the Income Shares Model prescribed by the guidelines schedule in Section 119.

After filing, you must formally serve the petition, summons, and Automatic Temporary Injunction notice on your spouse. Under Oklahoma Statutes Title 12, Section 2004, service must be performed by someone over 18 who is not a party to the case — you cannot serve your spouse yourself. Oklahoma permits three methods of service: personal service by a sheriff's deputy (approximately $50 plus $5 for notarization) or licensed private process server, certified mail with return receipt requested, or service by publication if the respondent's location is unknown. Personal service by a process server or sheriff is the most reliable method and creates the clearest proof of service. After service is completed, the server files a Return of Service (also called an Affidavit of Service) with the court clerk along with the original summons. The ATI becomes effective immediately upon service, restraining both parties from dissipating assets or removing children from Oklahoma. If your spouse voluntarily agrees to accept service, they may sign an Entry of Appearance and Waiver of Summons, eliminating the need for formal service.

After service, your spouse has 20 days to file an Answer with the court clerk, as required by Oklahoma Statutes Title 12, Section 2012. The answer responds to each allegation in the petition, either admitting or denying each claim. Your spouse may also file a Counterclaim, which raises new issues such as their own requests for custody, property division, or spousal support. If a counterclaim is filed, you must file a Reply to the Counterclaim within 10 days. If your spouse fails to file an answer within the 20-day deadline, you may request a default judgment, which allows the court to proceed based solely on the information in your petition and grant your requested relief without considering the respondent's position. A default judgment can be entered after the applicable waiting period has elapsed — 10 days from filing without children, or 90 days with children. Your spouse may also file a Reservation of Time, which extends their response deadline by an additional 20 days under Section 2012, giving them a total of 40 days to answer.

Oklahoma law under Title 43, Section 107.2 requires both parents in a divorce involving children under 18 years of age to attend a court-approved parenting education class covering the impact of divorce on children, co-parenting communication strategies, conflict management, the effects of family violence, reconciliation options, and the developmental needs of children at various ages. The class typically runs four hours and costs between $15 and $60 depending on the provider. Parents must attend together or separately — domestic violence victims can request to attend at a different time or location than the abusive spouse, and courts may grant an exemption from the class entirely in DV cases. The class must be completed and a Certificate of Completion filed with the court before the court will enter a final decree of divorce. Oklahoma State University's Co-Parenting for Resilience program and local providers such as the Center for Children and Families Inc. in Norman offer approved courses. Some counties may prohibit online courses, so check with your local court clerk before enrolling in a distance-learning option.

Oklahoma's Automatic Temporary Injunction under Title 43, Section 110 mandates that both spouses produce comprehensive financial disclosures once the ATI is in effect. Required disclosures include the past two years of federal and state income tax returns, two months of pay stubs from every employer, six months of bank account statements for all accounts (checking, savings, investment), health insurance coverage brochures and related documents, childcare expense documentation, and account statements for all debts showing payment terms and the most recent balance due. Beyond the ATI mandatory disclosures, Oklahoma's discovery rules under Title 12, Section 3226 permit either party to obtain additional financial information through interrogatories, requests for production of documents, depositions, and requests for admission. Both parties must also complete a Financial Affidavit listing all income, assets, liabilities, and monthly expenses. Failure to comply with disclosure obligations can result in contempt of court sanctions, adverse inferences at trial, award of attorney fees to the opposing party, and potential reopening of the case if hidden assets are later discovered.

Many Oklahoma counties require mediation before any contested hearing will be scheduled, pursuant to the District Court Mediation Act under Title 12, Sections 1801 through 1825. When mediation is ordered, both parties and their attorneys must select and contact a mediator or mediation program within five business days of the court's referral order. Mediation sessions must be attended by persons with full settlement authority, and each represented party must be accompanied by an attorney fully familiar with the case. Family law mediators in Oklahoma must have completed 40 hours of approved family and divorce mediation training and have at least four years of regular mediation practice, per Section 12-1825. The Early Settlement Mediation program, administered by the Oklahoma Alternative Dispute Resolution System through the Administrative Office of the Courts, resolved over 70% of cases mediated in fiscal year 2024. All communications during mediation are confidential and inadmissible as evidence under Section 12-1824. Mediation costs are typically shared equally between the parties unless the court orders otherwise. More information is available at oklahoma.gov/oamp.html.

If both parties can reach agreement on all issues — property division, debt allocation, spousal support, child custody, child support, and visitation — they should execute a written Marital Settlement Agreement (also called a Separation and Property Settlement Agreement) that addresses every contested issue. Oklahoma follows equitable distribution principles, meaning marital property is divided fairly though not necessarily equally, taking into account each spouse's contributions, earning capacity, and the length of the marriage. If minor children are involved, the agreement must include a detailed parenting plan and a child support computation compliant with the Guidelines Schedule under Title 43, Section 119. Both parties should review and sign the agreement, and it must be presented to the court for approval. If the parties cannot reach agreement, the case proceeds to trial where the judge will hear evidence and make rulings on all unresolved issues. Discovery — including interrogatories, document requests, and depositions under Title 12, Section 3226 — should be completed before trial to ensure both sides have full access to relevant information.

After the mandatory waiting period has elapsed — 10 days from filing for cases without minor children, or 90 days for cases with minor children under Title 43, District Court Rule 8 — you may schedule the final hearing with the court. File a Notice of Final Hearing to inform all parties of the hearing date, time, and location. At the final hearing, the petitioner must appear in court (the respondent must appear only if the case is contested or if ordered by the judge) and present testimony confirming jurisdiction, residency, grounds for divorce, and the terms of any settlement agreement. If minor children are involved, both parents' Certificates of Completion from the mandatory parenting education class under Section 43-107.2 must be filed before the court will enter the decree. The judge will review the agreement or hear contested evidence, then sign the Decree of Divorce, which becomes effective immediately upon the judge's signature. Oklahoma prohibits remarriage within six months of the date the divorce decree is granted under Title 43, Section 123. File the signed decree with the court clerk and obtain certified copies for your records.
