Overview

Clinton County is located in Missouri with a population of approximately 21,721. The Clinton 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, Chapter 473 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.

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

Missouri law sets a statutory fee schedule for attorneys and personal representatives based on the value of the estate (e.g., 5% on the first $5,000, 4% on the next $20,000, etc.), though additional fees may be allowed for extraordinary services.

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 small (statutory allowances apply), the court may "refuse" letters, allowing immediate transfer.
  • 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 Letters Testamentary or Administration with the Clinton County Circuit Court. Include:

  • Application for Letters
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee (typically ~$175.00 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.

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 Clinton County (e.g., Clinton County Leader) for four 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.

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 administrative 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
