Overview

St. Charles County is located in Missouri with a population of approximately 423,726. The St. Charles County Probate Court (Division of the 11th Judicial Circuit) 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 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.

Small Estate Affidavit: Missouri offers a simplified procedure for estates valued at $40,000 or less (less liens and encumbrances). This process, known as an "Affidavit to Establish Title of Distributee to Property in Estate of Less than $40,000," avoids full probate administration. If the value is over $15,000, publication in a local newspaper is required.

Statutory Fees: Missouri law sets a minimum compensation 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 (less liens and debts), you may file a small estate affidavit.
  • Non-Probate Transfers: Assets with beneficiary designations (POD/TOD accounts, life insurance) or held in trust generally do not require probate.
  • 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.

Step 2: File the Petition

If formal probate is needed, file a Petition for Letters Testamentary or Petition for Letters of Administration with the St. Charles County Probate Court. Include:

  • Original Last Will and Testament (if applicable)
  • Certified copy of the death certificate
  • Filing fee (typically varies by estate value)
  • Information about heirs and beneficiaries

E-filing is mandatory for attorneys in Missouri courts. Self-represented litigants may file in person or by mail, but should check with the clerk.

Step 3: Provide Notice

After filing, you must:

  • Mail notice to all heirs, beneficiaries, and interested parties.
  • Publish notice in a newspaper of general circulation in St. Charles County (such as the St. Charles County Business Record) for four consecutive weeks.
  • The court clerk typically handles the publication process upon filing.

Step 4: Attend the Hearing

The court may schedule a hearing to admit the will and appoint the personal representative. Once approved, the judge issues Letters Testamentary or Letters of Administration, granting authority to manage estate assets.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Notify creditors: Creditors have six months from the date of first publication to file claims.
  • Inventory and Appraise: File an inventory of all estate assets within 30 days of appointment.
  • Pay Debts and Taxes: Pay valid claims, expenses, and taxes.
  • Distribute Assets: After the statutory period and settlement approval, distribute remaining assets to beneficiaries.
  • File Final Settlement: File a final settlement and petition for discharge to close the estate.

Local Requirements

St. Charles County-Specific Procedures
