Overview

Oregon County is located in Missouri with a population of approximately 8,699. The Oregon County Circuit Court, Probate Division handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

Missouri probate is governed by Title XXXI of the Missouri Revised Statutes. The process begins with filing a Petition for Letters Testamentary (if there is a will) or Letters of Administration (if 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, Missouri offers a Small Estate Affidavit procedure if the entire estate, less liens and encumbrances, does not exceed $40,000. This allows for the transfer of assets without full probate administration after a 30-day waiting period.

Missouri law sets statutory compensation for personal representatives and attorneys based on a percentage of the estate value: 5% on the first $5,000, 4% on the next $20,000, 3% on the next $75,000, 2.75% on the next $300,000, 2.5% on the next $600,000, and 2% on amounts over $1 million.

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 $40,000 or less, you may file a small estate affidavit 30 days after death to transfer assets without full probate.
  • Non-Probate Transfers: Assets with beneficiary designations (POD/TOD), joint tenancy with rights of survivorship, or assets held in a living trust generally do not require probate.
  • Refusal of Letters: For surviving spouses or unmarried minor children, the court may "refuse" letters if the estate is small (statutory allowances apply), effectively closing it immediately.

Step 2: File the Petition

If formal probate is needed, file a Petition for Letters Testamentary or Administration with the Oregon County Circuit Court. Include:

  • Application for Letters
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee (typically ~$150-$200)
  • List of heirs and interested parties

E-filing is mandatory for attorneys in Missouri courts via the Case.net system. Pro se litigants may file in paper.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the hearing to all heirs, beneficiaries, and interested parties.
  • Publish notice in a newspaper of general circulation in Oregon County (such as The South Missourian News) for four consecutive weeks.

Step 4: Attend the Hearing

The court will review the petition. If approved, the judge 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:

  • Publish notice to creditors (claims must be filed within 6 months of first publication).
  • Inventory and appraise all estate assets within 30 days of appointment.
  • Pay valid creditor claims and estate expenses.
  • File federal and state tax returns as needed.
  • Distribute assets to beneficiaries.
  • File a Statement of Account and Petition for Distribution to close the estate.

Local Requirements

Oregon County-Specific Procedures

  • Local Court Rules: The 37th Judicial Circuit may have specific local rules regarding hearing schedules and document formatting. Check with the clerk.
