Before you begin — know the assets and liabilities
Before you choose a Harper County filing route, make a practical inventory of what the person owned, how each account or title was held, which debts are known, and whether any real property is in Harper County or another Oklahoma county. That asset map determines whether the estate settlement needs a court case, a shorter procedure, or a non-court transfer tool.
Sunset's 2,300-institution asset discovery helps families find bank, brokerage, retirement and insurance relationships before a petition is drafted. That can prevent missed accounts, wrong notices and extra trips to the courthouse in Buffalo.
Which court handles jurisdiction
Probate for Harper County is filed with the Harper County Court Clerk at the Harper County Courthouse, 311 S.E. 1st Street, Buffalo, in the District Court of Harper County. The courthouse serves all of Harper County.
Harper County is in Oklahoma's First Judicial District together with Beaver, Cimarron and Texas counties. That shared district is a judge assignment structure, not a shared filing counter. File a Harper County case in Buffalo, not in Beaver, Boise City or Guymon.
Oklahoma venue is tied to the county of proper venue: if the decedent died as an Oklahoma resident, the case belongs in the county where the decedent resided at death. For a nonresident decedent, Oklahoma uses the sequence in 58 O.S. § 5(2), beginning with the Oklahoma county where the decedent died leaving an estate, then an Oklahoma county where estate property is located.
The jurisdiction process
- Collect the death certificate, the original will if there is one, recent account statements, deeds, vehicle titles and a list of known debts before starting the Harper County estate settlement.
- Decide whether the matter needs a Harper County court case. Some assets pass by joint title, beneficiary designation, transfer-on-death deed or a small estate affidavit under 58 O.S. § 393; other estates need summary administration under 58 O.S. §§ 245-247 or regular probate, with dispensing with regular proceedings available only when 58 O.S. § 241 applies.
- Prepare the petition, the civil cover sheet, the proposed order setting hearing, the proposed letters and any required notice documents. If there is a will, bring the original will for filing.
- File the paper petition with the Harper County Court Clerk at the courthouse in Buffalo and pay the filing costs. The statutory probate flat fee is $135.00 under 28 O.S. § 152(A)(3), in the fee statute amended effective November 1, 2025, plus statutory add-ons including the $7.00 Dispute Resolution System cost under 12 O.S. § 1809(A), current as of August 2026. Confirm the total before filing.
- Obtain a hearing date and give the required notice. Oklahoma probate cases are decided by a district judge at noticed hearings, including hearings to admit a will, appoint a personal representative and later distribute the estate.
- If a party or witness wants to appear by video, ask when the matter is set. Oklahoma authorizes videoconferencing under 20 O.S. § 130 and Rule 34, but the judge has discretion and testimony by video has its own notice requirements.
- After appointment, the personal representative receives letters testamentary or letters of administration, takes any required oath, and completes any bond step the judge orders.
- Prepare the inventory, appraisement if required, and notice to creditors. The notice states a presentment date, and a claim not presented by that date is barred forever under 58 O.S. § 333.
- Administer the estate by collecting assets, handling creditor claims, selling property if the court authorizes a sale, and keeping records needed for the final account.
- File the final account and petition for distribution, give notice, attend the final hearing, and obtain the decree of distribution and discharge. If the decree affects real property, record it with the county clerk of every county where the land lies (58 O.S. § 711).

Scenarios
| Scenario | Likely Harper County path | Where Sunset helps |
|---|---|---|
| Surviving spouse with a co-owned home | First check the deed, any transfer-on-death deed and beneficiary designations. If the home passes outside probate, the Harper County court case may be narrower or unnecessary for that asset. | Sunset helps identify accounts, titles and beneficiary-linked assets before a spouse files unnecessary paperwork. |
| Out-of-state adult child with a small estate | Some assets may be collectable by affidavit under 58 O.S. § 393 without opening a Harper County case. If a court case is needed, a nonresident personal representative may serve but must appoint an in-county agent under 58 O.S. § 162. | Sunset helps organize the asset list, flag institutions to contact, and connect the child with Oklahoma counsel if a Buffalo filing is needed. |
| Parent settling predeceased child's estate, home must be sold | A court appointment is usually needed before signing for the estate. If real property is sold through the probate case, the separate sale proceeding carries a $43.00 charge under 28 O.S. § 152(A)(5), in the fee statute amended effective November 1, 2025. | Sunset helps assemble the asset and debt picture, generate a probate packet, and find a local probate attorney for the sale and final distribution. |
