How to File for Guardianship in Missouri: Step-by-Step for Relatives

Filing for guardianship of a minor in Missouri is a court process with a specific sequence, and skipping a step — or doing them out of order — can delay your case by weeks. Here is the actual filing process from start to Letters of Guardianship.

Step 1: Determine Your Circuit and Division

Guardianship of a minor goes through the probate division of the circuit court in the county where the child is domiciled. Missouri has 46 judicial circuits, and each has its own local rules and forms.

Before you do anything else, check whether your circuit allows pro se (self-represented) filings. Most do, but St. Louis County's probate division requires non-parent petitioners to have an attorney for full guardianship petitions. If your circuit mandates representation and you cannot afford a lawyer, contact Legal Aid — there are four regional offices covering the state.

Step 2: Complete Background Screenings

Missouri requires a background screening for the proposed guardian unless a statutory exception applies. Section 475.050.4 exempts public administrators and the minor's spouse, parent, adult child, or adult sibling. The screening must include:

• Department disqualification lists, adult and child abuse and neglect registries, a Missouri criminal-record review, and the sex-offender registry

The reports must be filed with the court at least 10 days before the appointment hearing, unless the court waives or modifies the deadline for good cause shown by an affidavit filed with the petition or the protected person requests an expedited hearing. Start this step early and follow your circuit's filing instructions.

Step 3: Prepare Your Petition

The core filing is a Verified Petition for Appointment of Guardian of Minor under RSMo § 475.060. The statute requires detailed information about the child, the parents, and the reason for appointment. It includes:

• The child's name, age, domicile, actual residence, and mailing address
• The names and addresses of the parents and whether they are living or dead
• Specific reasons why the parents are unfit, unwilling, or unable to provide care
• Whether another court has jurisdiction over the minor, and the name of that court if known
• Your qualifications as proposed guardian, if requested by the circuit's local form

Section 475.060.1 requires additional information as well; use the current circuit-court petition packet to confirm the complete list.

Attach parental consent forms if both parents agree. A minor over age 14 who has no qualified parent living may nominate a preferred guardian under RSMo § 475.045.1(2).

If you cannot afford court costs, prepare a Motion to Proceed In Forma Pauperis (RSMo § 514.040) with a financial affidavit.

Step 4: File and Serve

Submit your petition at the circuit clerk's office or electronically through the Missouri eFiling system if your circuit participates. Fees vary by circuit. Posted schedules list $100.50 for a minor-only case in Jackson County, $100.50 without service or $500.50 with service in St. Louis County, and a $760 advance deposit for minor guardianship and/or conservatorship in Greene County. Service costs may be additional.

Then serve notice on everyone required by RSMo § 475.070, including the parents, a minor over age fourteen, the person or entity nominated to serve as guardian, and the minor's spouse if applicable. This is not optional — failure to properly serve notice makes any resulting order void. Missouri uses:

• In-state summons service for nonconsenting parents by the sheriff or an adult who is not a party to the action, under Supreme Court Rule 54.13; the rule permits personal delivery or service at the parent's usual residence with an eligible adult resident or authorized agent
• Out-of-state parents: Probate notices may be sent by registered or certified mail to a U.S. address under RSMo § 472.100. If personal service of a summons is required, Supreme Court Rule 54.14 governs and requires service by someone authorized to serve process where the parent is located.
• Service through the warden for incarcerated parents
• Service by publication when service cannot be obtained by other authorized methods — only after filing the verified statement required by Supreme Court Rule 54.12(c), explaining why service cannot be made and giving the parent's last known address or stating it is unknown. Missouri courts require an honest and reasonable effort to locate the parent for personal service first.

Step 5: Wait for the Hearing

The court will schedule a hearing. Use this time to confirm all your service returns are filed, your background check results have reached the clerk, and your evidentiary documents are organized.

If a parent objects after being served, the case becomes contested. The court may appoint a Guardian ad Litem to represent the child's interests if it finds that representation would otherwise be inadequate, and it may schedule a more involved evidentiary hearing.

Step 6: Attend the Hearing

At the hearing, you testify under oath about your relationship to the child, your living situation, your ability to provide care, and why the parents cannot. Bring:

• Photo identification
• The child's certified birth certificate
• All filed background screening results
• Proof of service on both parents
• A proposed Judgment and Order Appointing Guardian

If the judge finds clear and convincing evidence that guardianship is necessary and in the child's best interests, the judge signs the order.

Step 7: Get Your Letters of Guardianship

The signed court order alone is not what you show to schools and hospitals. After the order is entered, the circuit clerk issues Letters of Guardianship — that document is your recognized legal proof of authority. Get several certified copies. Schools, medical providers, benefit offices, and banks will each want their own.
