Overview

Washington County is located in Oklahoma with a population of approximately 54,060. The Washington County District Court handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

Oklahoma probate is governed by Title 58 of the Oklahoma Statutes. The process begins with filing a Petition for Probate of Will (if there is a will) or Petition for Letters of Administration (if there is no will) to admit the will and appoint a personal representative. The court then issues Letters Testamentary for testate estates or Letters of Administration for intestate estates.

For smaller estates, Oklahoma offers a Small Estate Affidavit procedure if the estate's value is $50,000 or less. This allows heirs to collect assets without a full court proceeding after a 10-day waiting period.

Oklahoma law provides for statutory compensation for personal representatives and attorneys based on a percentage of the estate value (e.g., 5% of the first $1,000, 4% of the next $5,000, and 2.5% of amounts over $6,000).

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Small Estate Affidavit: If the estate is valued at $50,000 or less and includes no real estate, heirs may use an affidavit to collect assets 10 days after death.
  • Summary Administration: Available for estates valued at $200,000 or less, or if the decedent has been dead for more than 5 years.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If formal probate is needed, file a Petition for Probate with the Washington County District Court. Include:

  • Petition for Probate of Will or Letters of Administration
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee (approximately $220)
  • Order for Hearing

E-filing is available and often required for attorneys via the OSCN (Oklahoma State Courts Network) system.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the hearing to all heirs, beneficiaries, and interested parties at least 10 days before the hearing.
  • Publish notice in a newspaper of general circulation in Washington County (such as the Bartlesville Examiner-Enterprise) for two consecutive weeks.

Step 4: Attend the Hearing

The court will schedule a hearing on the petition, typically 2 to 4 weeks after filing. At the hearing, the judge reviews the petition and, if approved, issues Letters Testamentary or Letters of Administration.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors (creditors have 2 months to file claims after notice is filed).
  • Inventory and appraise all estate assets within 2 months of appointment.
  • Pay valid creditor claims and estate expenses.
  • File federal and state tax returns as needed.
  • Distribute assets to beneficiaries.
  • File a Final Account and Petition for Distribution to close the estate.
