Overview

St. Clair County is located in Missouri with a population of approximately 9,848. The St. Clair 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 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.

For smaller estates, Missouri offers a Small Estate Affidavit procedure if the value of the estate (less liens and encumbrances) does not exceed $40,000. This simplified process allows heirs to collect 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 an affidavit 30 days after death to transfer assets without full administration.
  • 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 Probate of Will and/or Letters Testamentary or Petition for Letters of Administration with the St. Clair County Circuit Court. Include:

  • Original Will (if applicable)
  • Certified death certificate
  • Filing fee (approximately $175.00 for full estates)
  • List of heirs and interested parties
  • Renunciations or consents from other heirs (if applicable)

Missouri courts utilize the Case.net system, but pro se litigants may need to file paper documents directly with the clerk.

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 St. Clair County, such as the St. Clair Courier, for four consecutive weeks.

Step 4: Attend the Hearing

The court will review the petition and, if approved, issue Letters Testamentary or Letters of Administration. This grants the personal representative the legal authority to act on behalf of the estate.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Publish notice to creditors (if not already done) and allow 6 months for claims.
  • 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 according to the will or state law.
  • File a Statement of Account and petition for discharge to close the estate.
