Before you begin — know the assets and liabilities
Before you file in Boise City, identify the assets, debts, ownership titles, beneficiary designations, and any original will. Cimarron County does not publish a local probate packet or fee sheet, so knowing what property actually needs court authority is the first step in choosing the right estate settlement path.
Sunset's 2,300-institution asset discovery helps families look for accounts, policies, and financial relationships before a petition is prepared. That matters in Cimarron County because a mailed or counter filing should be complete enough for the court clerk to accept and for the judge to set the first hearing.
Which court handles jurisdiction
Probate for Cimarron County is filed with the Cimarron County Court Clerk at the courthouse in Boise City, in the District Court of Cimarron County, which sits in Oklahoma's First Judicial District together with Texas, Beaver and Harper counties (20 O.S. § 92.2). Sharing a judicial district does not move the filing to Guymon, Beaver or Buffalo.
Use Cimarron County when the decedent was an Oklahoma resident whose county of residence at death was Cimarron County. For a nonresident decedent, Oklahoma venue follows the sequence in 58 O.S. § 5, starting with the Oklahoma county where the decedent died leaving an estate, then a county where Oklahoma estate property is located, then the county where the decedent died if there is no Oklahoma estate property. The courthouse in Boise City serves the county, including Boise City and the Kenton area.
The jurisdiction process
- Gather the death certificate, the original will if there is one, asset information, debt information, and title records before choosing the estate settlement route.
- Decide whether property can pass without a court case, whether a shortened Oklahoma procedure fits, or whether a regular probate case is needed. Do this before preparing a petition because Cimarron County does not publish a local petition packet.
- Prepare the petition, the Oklahoma civil cover sheet, proposed notices, and any proposed order or letters needed for the first hearing. The court clerk accepts filings but does not choose the route or prepare pleadings.
- File the paper originals with the Cimarron County Court Clerk at the courthouse on Courthouse Square or by mail to P.O. Box 788, Boise City, OK 73933. First Judicial District local rules say normal filing means original paper documents; fax or other electronic filing is disfavored and needs advance permission.
- Pay the filing cost. The current statutory schedule, last amended effective November 1, 2025, lists a $135.00 probate flat fee (28 O.S. § 152(A)(3)), plus statutory add-ons, and the Cimarron County Court Clerk should confirm the current amount due.
- The case is assigned under the First Judicial District's local rules to the Associate District Judge for Cimarron County. The judge sets a noticed hearing to admit the will if there is one, determine appointment, and issue the proper authority document.
- Attend the hearing as set. The regular Cimarron County motion and pretrial docket is the first and third Thursday of each month at 10:00 a.m., but a particular probate hearing may be placed on that docket or specially set by the judge.
- After appointment, the personal representative receives letters testamentary or letters of administration, files any required oath and any bond the judge orders, and begins administering the estate.
- Publish and mail the notice to creditors. The notice states the presentment date, and claims not presented by that date are barred forever under 58 O.S. § 333.
- Prepare the inventory, handle allowed claims, collect assets, and request court approval for any sale or other action that requires a separate order.
- File the final account and petition for distribution, give required notice, attend the final hearing, and obtain the decree of distribution and discharge.
- If the decree affects real property, record a certified copy with the county clerk in each county where the land is located (58 O.S. § 711). That recording step is separate from filing the probate case with the court clerk.
Forms and documents
Probate forms in Cimarron County
Cimarron County does not publish local probate forms, a local probate cover sheet, or a local probate checklist. The First Judicial District's local court rules are current and govern filing practice, remote appearance, and docket assignments, but they do not create a Cimarron County probate packet.

Timeline
- The First Judicial District's local rules set the regular Cimarron County day for defaults, motions, preliminary proceedings, and pretrial matters as the first and third Thursday of each month at 10:00 a.m. A probate hearing may be set on that docket or specially set by the judge, so confirm the actual hearing date and time with the Cimarron County Court Clerk when notice is issued.
Local nuance
Cimarron County-specific considerations
| Local point | What it means for a Cimarron County filing |
|---|---|
| Shared First Judicial District | Cimarron County shares Oklahoma's First Judicial District with Texas, Beaver and Harper counties, but a Cimarron County probate case is filed and heard in Boise City. |
| Local assignment | First Judicial District local rules assign probate, guardianship, joint tenancy, life tenancy termination, and mental health cases to the Associate District Judge in each county. Do not send filings to another county because the district is shared. |
| Paper filing | Original paper filing is the normal practice. Fax or other electronic filing is disfavored and requires advance permission from the court clerk or leave of court. |
| Remote appearance | Local rules expect in-person appearance. Telephone or video appearance is allowed only in special circumstances at the presiding judge's discretion and must comply with Rule 34. |
| Hours | Public listings give a 9:00 a.m. opening and a noon closure, while the 2026 local rules state an 8:00 a.m. opening. Call before traveling to the courthouse. |
| Case records | Cimarron County dockets are on ODCR, not OSCN. Online coverage begins July 18, 2001, and older records require contacting the court clerk. |
| Kenton and time | Kenton, in far western Cimarron County near the New Mexico line, is popularly known for keeping Mountain Time. The federal Central and Mountain time-zone boundary runs along Oklahoma's western state line (49 CFR § 71.7), and the courthouse in Boise City operates on Central Time. |

Scenarios
| Situation | Likely Cimarron County path | Where Sunset helps |
|---|---|---|
| Surviving spouse with a co-owned home | Check the deed before filing. If the home was held in joint tenancy or has a transfer-on-death deed, the home may need a title-clearing step rather than a full estate case. If court authority is needed, file in Boise City with the Cimarron County Court Clerk. | Sunset helps identify accounts, locate title clues, organize the will and deed information, and prepare the estate settlement packet for attorney review or filing. |
| Out-of-state adult child with a small estate | Start by determining what Oklahoma property actually needs court action. If an affidavit route under 58 O.S. § 393 fits, it is presented to the holder of the property rather than filed as a court case. If a Cimarron County case is needed, plan for paper filing and possible travel because local rules expect in-person appearance. | Sunset helps find financial institutions, organize debts and heirs, and connect the family with Oklahoma counsel if the child cannot manage the Boise City filing alone. |
| Parent settling a predeceased child's estate, home must be sold | A sale usually requires letters for a personal representative and any needed sale approval from the District Court of Cimarron County. A separate statutory fee for a sale or lease proceeding under 28 O.S. § 152(A)(5) may apply under the current statutory schedule, last amended effective November 1, 2025. | Sunset helps build the asset list, generate a document checklist, track deadlines, and find a local probate attorney for the sale and closing steps. |
