Overview

Johnson County is located in Missouri with a population of approximately 55,900. The Circuit Court of Johnson County, 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 470-475). 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.

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

Missouri law sets statutory fees for attorneys and personal representatives based on a percentage of the estate value (e.g., 5% on the first $5,000, 4% on the next $20,000, etc.), though additional fees may be allowed for extraordinary services.

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 of liens), 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 Circuit Court of Johnson County. Include:

  • Petition for Letters Testamentary or Administration
  • Original will and codicils (if applicable)
  • Certified death certificate
  • Filing fee (approximately $135-$150, varies by case type)
  • List of heirs and interested parties

Electronic filing (eFiling) is mandatory for attorneys in Missouri courts.

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 Johnson County (e.g., Daily Star-Journal) for four consecutive weeks.

Step 4: Attend the Hearing

The court will schedule a hearing on the petition. At the hearing, the judge reviews the petition and, if approved, 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 of first publication)
  • 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
