Overview

Atchison County is located in Missouri with a population of approximately 5,305. The Atchison 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 Chapter 473 of the Missouri Revised Statutes. The process begins with filing a Petition for Letters Testamentary (if there is a will) or a 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 an Affidavit for Collection of Small Estate, can be filed 30 days after death and is significantly faster and less expensive than full probate.

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:

* 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 (net value), you may file an Affidavit for Collection of Small Estate after a 30-day waiting period.
  • Refusal of Letters: For surviving spouses or unmarried minor children, the court may "refuse" letters if the estate is small (statutory allowances apply), effectively transferring assets without full administration.
  • 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 Atchison County Circuit Court. Include:

  • Petition for Probate of Will and/or Letters
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee (approximately $155.50 for full estates)
  • List of heirs and interested parties

Missouri utilizes the Case.net system, and e-filing is mandatory for attorneys in many circuits. Check with the clerk for pro se filing options.

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 Atchison County (such as the Atchison County Mail) 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:

  • Notify creditors: Creditors have 6 months from the date of 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 discharge to close the estate.

Local Requirements

Atchison County-Specific Procedures

  • Local Rules: The 4th Judicial Circuit may have specific local rules regarding scheduling and document formatting.
  • Publication: Notice is typically published in the Atchison County Mail or Tarkio Avalanche.
