Overview

Johnston County is located in Oklahoma with a population of approximately 10,272. The Johnston 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.

Oklahoma offers a Small Estate Affidavit procedure for estates valued at $50,000 or less (excluding real estate). This allows successors to collect personal property without full probate. Additionally, a Summary Administration process is available for estates valued at $200,000 or less, or if the decedent has been dead for more than five years.

Oklahoma law provides for statutory compensation for personal representatives and attorneys based on the value of the estate: 5% on the first $1,000, 4% on the next $5,000, and 2.5% on 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 consists of personal property valued at $50,000 or less, you may be able to use an affidavit to collect assets without court supervision.
  • Summary Administration: Available if the estate value is $200,000 or less, or the decedent has been deceased for more than 5 years. This is a faster court process.
  • 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 Johnston County District Court. Include:

  • Original Will (if applicable)
  • Certified death certificate
  • Filing fee (approximately $200+)
  • List of known heirs and beneficiaries

Oklahoma courts generally utilize the Oklahoma State Courts Network (OSCN) or On Demand Court Records (ODCR) systems, though e-filing availability varies by county. Contact the clerk to confirm current filing methods.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the hearing to all heirs, beneficiaries, and creditors at least 10 days before the hearing.
  • Publish notice in a newspaper of general circulation in Johnston County (such as the Johnston County Sentinel) for two consecutive weeks.

Step 4: Attend the Hearing

The court will schedule a hearing on the petition. At the hearing, the judge reviews the petition and, if approved, issues Letters Testamentary or Letters of Administration, granting the personal representative authority to act.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors (creditors typically 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 taxes.
  • Distribute assets to beneficiaries.
  • File a Final Account and Petition for Distribution to close the estate.
