Missouri Guardianship Process: Step-by-Step Filing Guide for Adult Children

The Basic Sequence, Start to Finish

Filing for guardianship over an elderly parent in Missouri is a formal legal proceeding through the probate division of the circuit court in the county where your parent lives. It's not a form you fill out and file — it's a lawsuit, governed by Missouri probate statutes and applicable civil-procedure rules, with mandatory respondent protections built in.

Here's the chronological sequence:

1. Obtain a medical capacity evaluation from your parent's physician or a neuropsychologist
2. File a Petition for Appointment of Guardian (and/or Conservator) in probate court
3. The court appoints independent defense counsel for your parent — this is mandatory, not optional
4. Personal service is executed on your parent by a county sheriff or approved process server
5. Notice is mailed to all interested persons (spouse, parents, adult children) at least 10 days before the hearing
6. Complete required background screening: if you are not exempt, register with the Family Care Safety Registry (FCSR), submit fingerprints, and complete any required credit check
7. Attend the evidentiary hearing where you present medical evidence of incapacity
8. If appointed: post a surety bond (for conservatorship), file an inventory within 30 days, and obtain certified Letters from the clerk

The whole process typically takes 30 to 90 days from filing to hearing, assuming no family disputes.

Step 1: The Medical Affidavit

Before you file anything, you need a physician's written statement confirming your parent lacks the capacity to manage their personal affairs. Courts require "clear and convincing evidence" of incapacity — a higher standard than the "preponderance" used in most civil cases.

The medical affidavit should detail:

• The clinical diagnosis (dementia, stroke-related cognitive impairment, etc.)
• Specific cognitive deficits observed during examination
• Functional limitations — what the parent can and cannot do independently
• The physician's opinion on whether the incapacity is permanent or potentially reversible

If your parent refuses to be evaluated, you can file a Motion for Mental or Medical Examination asking the court to order the assessment.

Step 2: Filing the Petition — County-Specific Forms

Missouri's court system is decentralized, which means filing requirements vary by circuit. This catches more families off guard than anything else in the process.

St. Louis County (21st Judicial Circuit): All filings must be electronic. The required packet is CCPR303 — a multi-page set that includes the petition, Exhibit A (a secured financial statement protected from public Case.net viewing), Exhibit B (list of interested persons), and Exhibit F (a consent form requiring three non-household references and your spouse's employer details). The base filing fee is approximately $115.50.

Jackson County (16th Judicial Circuit): Uses Form 10193 plus supporting exhibits and information sheets. Jackson County enforces a strict 30-day deficiency rule — if any required form is incomplete or missing, the clerk issues a deficiency checklist, and failure to cure within 30 days results in automatic dismissal for failure to prosecute at your cost.

Outstate circuits: Smaller counties generally accept paper filings and may have their own local packet. Filing fees range from $148.50 (Platte County) to $358.50 (Barry County, which includes a guardian ad litem deposit in the base fee).

Contact the probate clerk in your parent's county before filing. Ask specifically what their local packet includes and whether electronic filing is required or optional.

Steps 3–5: Service, Notice, and Defense Counsel

Once your petition is filed and a hearing date is set, three things happen in parallel:

Defense counsel: The court must appoint an independent attorney to represent your parent within 24 to 48 hours of filing. This attorney advocates for your parent's expressed wishes — even if those wishes conflict with what the family believes is in the parent's best interest. The defense attorney cannot also serve as the Guardian Ad Litem (GAL), who represents the parent's objective "best interests" in contested cases.

Personal service: A county sheriff or court-approved process server must personally deliver the petition, notice of hearing, and notice of rights to your parent. This cannot be waived or replaced with mail service — it's a constitutional protection.

Mail notice: All interested persons — your parent's spouse, parents, and adult children — must receive a copy of the petition and notice of hearing via ordinary or certified mail at least 10 days before the trial date.

Step 6: Background Screening

Non-exempt proposed guardians and conservators must complete the required background screening, including Family Care Safety Registry (FCSR) registration, fingerprints, and the required state background checks. Proposed conservators also submit a credit-history investigation. The FCSR registration fee is $15 plus a small online processing fee. Results must be filed at least 10 days before the hearing.

A proposed guardian or conservator who is the respondent's spouse, parent, adult child, or adult sibling is exempt from these screening requirements; other close relatives may not be. Confirm the exemption and the local filing packet before paying the fee or filing.

Step 7: The Hearing

The probate hearing is a formal evidentiary proceeding. You'll present:

• The medical affidavit and, if needed, live testimony from the evaluating physician
• Evidence that less restrictive alternatives (DPOA, supported decision-making) are insufficient
• Your qualifications to serve as guardian and your proposed care plan

If no one contests the petition and the medical evidence is clear, many judges handle uncontested hearings in 30 to 60 minutes. Contested cases — especially those involving sibling disputes — can stretch over multiple hearing dates and add thousands in attorney fees.

After Appointment: Ongoing Obligations

Guardianship doesn't end at the hearing. Once appointed, you're subject to continuous court oversight:

• Guardians must file an annual status report describing the ward's living situation, medical condition, and care being provided
• Conservators must post a corporate surety bond (with an annual premium estimated at approximately 0.5% of the total estate value), file a detailed inventory within 30 days, and submit annual financial settlements accounting for every dollar received and spent
• Annual filing fees of approximately $30 apply for processing the conservator's settlement
