How Long Does the Adult Guardianship Process Take in Missouri Probate Courts?

Current as of: October 1, 2026 Guardianship & Conservatorship Missouri
An uncontested adult guardianship in Missouri generally takes 4 to 8 weeks from the date the petition is filed to the final court hearing. However, emergency situations can be addressed in just a few days through a temporary 90-day guardianship order.

When an aging parent suffers severe cognitive decline or a young adult with special needs turns 18, securing the legal authority to make their medical and financial decisions is a pressing concern. Families often wonder how quickly the Missouri probate court system can move. The timeline for obtaining an adult guardianship or conservatorship is strictly governed by state statutes designed to balance efficiency with the profound constitutional right of an individual to manage their own life.

Whether you are filing in Columbia, Clayton, or Independence, waiting for the legal process to unfold can be stressful, especially when medical care or facility placement is pending. Having an experienced legal professional handle the filing ensures that missing documents or improperly formatted notices do not cause unnecessary delays. We encourage you to search our US Lawyers directory to find a skilled Missouri probate attorney who can navigate these timelines efficiently.

Step-by-Step Statutory Timelines

The timeline is not arbitrary; it is built around mandatory waiting periods and background investigations dictated by Missouri law.

Notice and Service Requirements

Once your attorney files the initial paperwork, specifically a Petition for Appointment of Guardian and Conservator under Mo. Rev. Stat. § 475.060 and Mo. Rev. Stat. § 475.061, the court does not schedule a hearing for the next day. Under Mo. Rev. Stat. § 475.075, the allegedly incapacitated person (the respondent) must be served in person a reasonable time before the date set for the hearing. In addition, notice to close family members and other interested parties is governed by Mo. Rev. Stat. § 472.100 (requiring at least 14 days when served by ordinary mail) or applicable local court rules. This ensures the respondent has time to consult with their court-appointed attorney or Guardian ad Litem (GAL) and prepare a defense if they wish to object.

Background Check Delays

Missouri courts will not hand over control of a vulnerable adult's life and finances to someone with a history of financial crimes or elder abuse. Under Mo. Rev. Stat. § 475.050, every prospective guardian must pass an extensive criminal registry review. Your attorney will help you submit Form SHP-158, Missouri, Highway Patrol, Request for Criminal Record Check to the Missouri State Highway Patrol, Jefferson City, as well as Form MO 300-1590, Missouri, Department of Health and Senior Services, Caregiver Background Screening Form. Processing these background checks usually takes 1 to 3 weeks, and the final hearing cannot occur until the judge has reviewed the clean reports.

Emergency 90-Day Timelines

If the 4 to 8-week timeline is too slow because the adult faces an immediate risk of severe physical harm or financial ruin (such as an ongoing scam draining their bank accounts), you can file for temporary relief. Under Missouri law, an emergency temporary guardianship or conservatorship can be granted almost immediately, sometimes within 24 to 48 hours of filing. However, this emergency order is strictly limited to 90 days. During that 90-day window, you and your attorney must proceed with the standard process to convert the temporary order into a permanent one.

Factors that Prolong Contested Hearings

If the case is contested, the 4 to 8-week timeline is entirely out the window. A contested case at the St. Louis County Circuit Court, Probate Division, Clayton or the Boone County Circuit Court, Probate Division, Columbia can easily drag on for 6 months to over a year. Several factors cause these massive delays:

  • Family Disputes: If siblings cannot agree on who should serve as the guardian, the judge must hold an evidentiary hearing to decide who is best suited for the role.
  • Medical Disagreements: The respondent has the right to demand an independent medical evaluation. If the GAL's doctor says the person is incapacitated, but the respondent's hired doctor says they are fine, the court must schedule a full trial to weigh the medical testimony.
  • Jury Trial Demands: Under Mo. Rev. Stat. § 475.075, the respondent has the right to demand that a jury, rather than just a judge, decide whether they are truly incapacitated. Scheduling a jury trial in probate court takes significant time.

How Much Does it Cost in Missouri?

The timeline directly affects the cost. A swift, uncontested 30-day process requires less of your attorney's time.

Uncontested Permanent Guardianship (4-8 weeks)$2,500 to $5,000
Emergency Temporary + Permanent (Expedited)$3,500 to $6,500 (extra filings required)
Contested Guardianship Trial (6-12+ months)$10,000 to $25,000+

Frequently Asked Questions (FAQ)

What is the role of the Guardian ad Litem (GAL)?

The GAL is a court-appointed attorney representing the allegedly incapacitated person. They must visit the person, review the medical evidence, and submit a report to the judge recommending whether the guardianship should be granted or denied.

Can a guardianship be completed faster if the adult consents?

Even if the adult completely agrees that they need help and signs a consent waiver, the court must still ensure proper statutory notice is provided under Mo. Rev. Stat. § 475.075 and wait for the mandatory background checks to clear before entering a final appointment order.

Do we have to go to court in person?

Yes, a hearing is mandatory. In some Missouri counties, judges allow uncontested hearings to be conducted via secure video conference (like Webex or Zoom), but the petitioner and the GAL must still officially present evidence to the judge.

Can a Power of Attorney prevent the need for guardianship?

Yes. If the adult signed a comprehensive Durable Power of Attorney and Healthcare Directive while they still had mental capacity, a guardianship process is often entirely unnecessary, saving the family months of time and thousands of dollars.
