Overview

Warren County is located in Missouri with a population of approximately 38,478. The Circuit Court of Warren County, 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 Missouri Revised Statutes, Chapter 473. The process begins with filing an Application for Letters Testamentary (if there is a will) or Application 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.

Small Estate Affidavit: Missouri offers a simplified procedure for estates valued at $40,000 or less (excluding liens and encumbrances). This process, known as an Affidavit for Collection of Small Estate, can be filed 30 days after death and is significantly faster and less expensive than formal probate.

Statutory Fees: Missouri law sets a minimum fee schedule for attorneys and personal representatives based on the value of the estate's personal property and proceeds from real estate sold:

* 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

* 2% on amounts over $1,000,000

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 $40,000 or less, you may file an Affidavit for Collection of Small Estate after a 30-day waiting period.
  • Refusal of Letters: For surviving spouses or unmarried minor children, the court may grant a "Refusal of Letters" if the estate value does not exceed the statutory allowance (typically $20,000 for spousal refusal).
  • 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 Circuit Court of Warren County. Include:

  • Application for Letters Testamentary or Administration
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee (typically $150–$200 for full estates)
  • List of heirs and interested parties

Note: Missouri courts utilize the Case.net system. Attorneys are generally required to e-file documents.

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 Warren County, such as the Warren County Record, once a week for four consecutive weeks.

Step 4: Attend the Hearing

The court will review the application. If approved, the judge issues Letters Testamentary or Letters of Administration, granting the personal representative authority to act on behalf of the estate.

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 discharge to close the estate.
