Overview
Oklahoma has not adopted the Uniform Probate Code (UPC), instead maintaining its own probate statutes under Title 58 of the Oklahoma Statutes. Probate cases are handled by the district courts in each county.
Oklahoma offers three main probate tracks:
- Small Estate Affidavit — for estates with personal property valued at $50,000 or less and no real property, bypassing probate entirely
- Summary Administration — a streamlined probate process for estates valued at $200,000 or less, or when the decedent has been dead for more than 5 years, or when the decedent lived outside Oklahoma
- Regular (Full) Administration — standard court-supervised probate for larger or more complex estates
Oklahoma does not impose a state estate tax or inheritance tax, which eliminates a significant administrative burden for most families. Only the federal estate tax applies for very large estates.
Oklahoma is one of the states with a statutory attorney fee schedule for probate, providing predictability for families but also meaning attorney costs are fixed by law rather than negotiated.
When Probate is Required
Probate is required in Oklahoma when a decedent owned assets in their sole name that do not transfer automatically at death. Common examples include:
- Real property titled solely in the decedent's name or as tenants in common
- Bank accounts and investments without payable-on-death (POD) or transfer-on-death (TOD) designations
- Vehicles and titled personal property in the decedent's sole name
- Business interests held individually
- Oil, gas, and mineral rights — a common asset type in Oklahoma
Probate is generally not required for:
- Joint tenancy property — passes automatically to the surviving joint tenant(s)
- Beneficiary-designated assets — life insurance, retirement accounts, POD/TOD accounts
- Property held in a revocable living trust
- Small personal estates valued at $50,000 or less with no real property — these can be handled with a small estate affidavit
- Multiple-party accounts with survivorship designations
Oklahoma's summary administration process makes it possible to handle many moderate-sized estates efficiently without the full complexity of regular probate.
Small Estate Options
Oklahoma provides a small estate affidavit process (58 O.S. § 393) that allows successors to collect personal property without opening a probate case.
Eligibility requirements:
- The total value of the decedent's personal property (excluding real property) must not exceed $50,000
- The estate must not include any real property
- At least 30 days must have passed since the decedent's death
- No petition for appointment of a personal representative is pending or has been granted
How the process works:
- The successor prepares a Small Estate Affidavit stating their right to the property
- The affidavit is signed under oath and notarized
- The completed affidavit is presented directly to banks, financial institutions, employers, or others holding the decedent's property
- The institution must release the property to the affiant upon receiving the valid affidavit
- No court filing is required
Important limitations:
- This process does not transfer real property — summary administration or full probate is needed for real estate
- The affiant becomes personally liable for claims and debts of the estate up to the value of property received
- If disputes exist among heirs, formal probate may be necessary
- Oil, gas, and mineral rights are considered real property and cannot be transferred via affidavit
Step-by-Step Process
1. Determine the appropriate probate track
Assess the estate's assets, value, and circumstances. Use the small estate affidavit for personal property under $50,000. Use summary administration for estates under $200,000. Use regular administration for larger or complex estates.
2. File the petition
For summary administration, file a Petition for Summary Administration with the district court in the county where the decedent was domiciled. For regular administration, file a Petition for Probate of Will (testate) or Petition for Letters of Administration (intestate). Filing fees are approximately $200 to $250.
3. Provide notice
In summary administration, notice must be given to all heirs and devisees. The court typically requires a hearing 50 to 60 days after filing. In regular administration, publish a Notice to Creditors in a newspaper of general circulation for two consecutive weeks.
4. Court hearing and appointment
Attend the court hearing. In summary administration, the court may approve distribution in a single hearing. In regular administration, the court appoints the personal representative and issues Letters Testamentary or Letters of Administration.
5. Post bond if required
Oklahoma generally requires the personal representative to post a surety bond unless the will waives the bond requirement. The bond amount is set by the court.
6. Inventory and appraisement
Within 2 months of appointment, file an Inventory and Appraisement listing all estate assets and their fair market values. The court may appoint an appraiser.
7. Publish notice to creditors
Publish the Notice to Creditors in a local newspaper for two consecutive weeks. Creditors have 2 months from the date of first publication to present claims.
8. Pay debts, claims, and taxes
Review and pay valid creditor claims in statutory priority order. File the decedent's final federal and Oklahoma state income tax returns. Oklahoma has no state estate tax, so only the federal estate tax applies for qualifying estates.
9. File the final account
Prepare and file a Final Account and Petition for Decree of Distribution with the court. The account must detail all assets received, debts paid, expenses incurred, and proposed distributions.
10. Distribution and closing
After the court approves the final account, distribute remaining assets according to the will or Oklahoma's intestacy laws. The court issues a Decree of Distribution and formally closes the estate.
Timeline & Costs
Typical timeline:
- Small estate affidavit: A few weeks (available 30 days after death)
- Summary administration: 50 to 90 days
- Regular administration: 6 to 12 months
- Complex or contested estates: 1 to 3+ years
Summary administration is significantly faster than regular probate, typically completing in about 50 to 60 days.
Court filing fees:
- Small estate affidavit: $0 (no court filing required)
- Summary administration: $200–$250
- Regular administration: $200–$250
Personal representative compensation:
Oklahoma sets compensation by statute: 2.5% to 5% of the estate value, depending on the size and complexity of the estate (58 O.S. § 527).
Attorney fees:
Oklahoma has a statutory fee schedule for probate attorneys:
- 5% of the first $1,000
- 4% of the next $4,000
- 2.5% of the remainder
For a $200,000 estate, the statutory attorney fee would be approximately $5,060. The court may allow additional fees for extraordinary services.
Additional costs:
- Newspaper publication: $100 to $250
- Certified copies of Letters: $5 to $15 per copy
- Surety bond premiums: varies by estate size
- Appraisal fees: varies by asset type

Unique State Rules
Summary administration for estates under $200,000
Oklahoma's summary administration process is a significant advantage for moderate-sized estates. Available when the estate value does not exceed $200,000, the decedent has been dead more than 5 years, or the decedent was a nonresident, this streamlined process can typically be completed in 50 to 60 days — much faster than the 6-to-12-month timeline for regular probate.
No state estate tax or inheritance tax
Oklahoma does not impose a state estate tax or inheritance tax. Only the federal estate tax applies, currently affecting estates exceeding approximately $13.99 million (2025). This makes Oklahoma one of the more tax-friendly states for estate administration.
Statutory attorney fee schedule
Oklahoma establishes probate attorney fees by statute: 5% of the first $1,000, 4% of the next $4,000, and 2.5% of the remainder. This provides cost predictability but means fees are not negotiable for routine services. The court may approve additional fees for extraordinary services.
Oil, gas, and mineral rights
Oklahoma has significant oil and gas production, making mineral rights a common probate asset. Mineral rights are treated as real property and cannot be transferred via small estate affidavit. They must go through summary or regular probate administration and may require specialized appraisals.
Short creditor claim period
Oklahoma's creditor claim period is 2 months from the date of first publication of the notice to creditors — one of the shortest in the country. This shorter period helps estates close more quickly.
Not a UPC state
Oklahoma has not adopted the Uniform Probate Code. Its probate procedures are governed by Title 58 of the Oklahoma Statutes, which predates the UPC and includes some unique procedural requirements.
Muniment of title
Oklahoma allows a will to be admitted as a muniment of title when there are no unpaid debts (other than secured debts). This simplified proceeding can transfer real property without full probate administration.
