Overview

Barton County is located in Missouri with a population of approximately 11,637. The Barton 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 an Application for Letters Testamentary or Letters of Administration 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 known as the Small Estate Affidavit for estates valued at $40,000 or less (excluding liens and encumbrances). This can be filed 30 days after death. There is also a "Refusal of Letters" process for surviving spouses or unmarried minor children if the estate is necessary for their support.

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 (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 if the estate is necessary for their support.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If formal probate is needed, file an Application for Letters Testamentary or Letters of Administration with the Barton County Circuit Court. Include:

  • Application for Letters
  • Original will and codicils (if any)
  • Certified death certificate
  • Filing fee (approx. $135.00 - contact court for current schedule)
  • List of heirs and addresses

Missouri courts generally require e-filing for attorneys via Case.net; pro se litigants may file in paper.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the hearing to all heirs, beneficiaries, and interested parties at least 10 days before the hearing (if a hearing is required for appointment)
  • Publish notice in a newspaper of general circulation in Barton County for four consecutive weeks

Step 4: Attend the Hearing

The court will schedule a hearing on the petition, typically 4 to 6 weeks after filing. At the hearing, the judge reviews the petition and, if approved, issues Letters Testamentary or Letters of Administration.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Publish notice to creditors (claims barred 6 months after first publication)
  • Inventory and appraise all estate assets within 30 days
  • Pay valid creditor claims
  • File federal and state tax returns as needed
