Overview

Marion County is located in Missouri with a population of approximately 28,425. The Marion 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 of the Missouri Revised Statutes (Chapters 472-475). 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.

Small Estate Affidavit: Missouri offers a simplified procedure for estates valued at $40,000 or less (excluding liens and encumbrances). This process, known as a "Small Estate Affidavit," can be filed 30 days after death and avoids full probate administration.

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

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, the court may "refuse" letters if the estate is small (statutory allowances apply).
  • 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 with the Marion County Circuit Court. Include:

  • Petition for Probate of Will and/or Letters Testamentary/Administration
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee (typically ~$150-$200)
  • List of heirs and interested parties

Missouri courts utilize the Case.net system, and attorneys are generally required to e-file.

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 Marion County (e.g., Hannibal Courier-Post or Palmyra Spectator) 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 (claims must be filed within 6 months).
  • 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 Distribution to close the estate.

Local Requirements

Marion County-Specific Procedures

  • Publication: Notice to creditors is standard and must be published in an approved county newspaper.
