Overview

Washington County is located in Missouri with a population of approximately 23,500. The 24th Judicial 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, Chapters 472-475 of the Revised Statutes of Missouri (RSMo). The process begins with filing an Application for Letters 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.

Missouri offers a simplified procedure for small estates. If the value of the estate (less liens and encumbrances) does not exceed $40,000, heirs may file a Small Estate Affidavit 30 days after death to transfer assets without full probate administration.

Missouri law sets statutory compensation for attorneys and personal representatives 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.
  • Refusal of Letters: For surviving spouses or unmarried minor children, if the estate is not greater than the exempt property allowance.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If formal probate is needed, file an Application for Letters with the 24th Judicial Circuit Court. Include:

  • Application for Letters Testamentary or Administration
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee (typically ~$155.50 for full estates)
  • List of heirs and interested parties

Missouri courts utilize the Case.net system, and e-filing is mandatory for attorneys in many circuits. 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 Washington County (e.g., The Independent Journal) for four consecutive weeks.

Step 4: Attend the Hearing

The court will review the application. If approved, the judge issues Letters Testamentary (with a will) or Letters of Administration (without a will), granting the personal representative authority to act.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Publish notice to creditors (creditors have 6 months to file claims)
  • Inventory and appraise all estate assets within 30 days of appointment
  • Pay valid creditor claims and taxes
  • File an annual settlement if the estate is open longer than a year
  • Distribute assets to beneficiaries
  • File a Statement of Account and petition for discharge to close the estate
