Overview

Mercer County is located in Missouri with a population of approximately 3,538. The Circuit Court of Mercer 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 Title XXXI of the Missouri Revised Statutes (Chapters 473-475). The process begins with filing a Petition for Letters Testamentary (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.

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

Missouri law sets statutory minimum fees for attorneys and personal representatives based on a percentage of the estate's 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 (less liens and encumbrances), you may file a small estate affidavit 30 days after death.
  • Refusal of Letters: For surviving spouses or unmarried minor children, the court may refuse letters if the estate value is not greater than the exempt property and allowance limits.
  • 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 Petition for Letters of Administration with the Circuit Court of Mercer County. Include:

  • Original Will and codicils (if any)
  • Certified death certificate
  • Filing fee (typically ~$155.50 base fee, varies by estate value)
  • List of heirs and beneficiaries with addresses
  • Corporate surety bond (unless waived in the will or by heirs)

Missouri courts utilize the Case.net system, and e-filing may be mandatory for attorneys.

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 Mercer County (e.g., Princeton Post-Telegraph) once a week 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 (creditors have 6 months from first publication to file claims).
  • 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.
