Physician Interrogatories Missouri Guardianship

What Missouri Courts Require from the Doctor

Every adult guardianship petition in Missouri must include a formal physician's evaluation — either a Physician's Affidavit or completed medical interrogatories. This document is the court's primary evidence of incapacity. Without it, your petition cannot proceed. The evaluation must come from a licensed physician or mental health professional who has examined the respondent within the preceding 30 to 60 days of filing.

The purpose is not to confirm a diagnosis. The court already knows your adult child has autism, Down syndrome, or intellectual disability. What the judge needs is a functional assessment: what specific decisions can this person make, what can they not make, and what support systems exist for the gap.

What the Evaluation Must Document

Missouri probate judges look for specific elements in the physician's statement:

Cognitive and functional capacity:

• Can the person understand cause and effect for daily decisions?
• Can they communicate preferences (in any modality — verbal, AAC, sign, gesture)?
• Can they understand the concept of delegating authority to another person?
• Can they identify trusted individuals versus strangers?

Specific domain limitations:

• Medical: can they understand treatment options, medication purposes, surgical consent?
• Financial: can they manage money, understand contracts, resist predatory offers?
• Personal safety: can they identify dangerous situations and respond appropriately?
• Residential: can they manage basic self-care and household needs independently?

What the person CAN do with support:

• This is where many evaluations fail. A form that only lists deficits provides no basis for limited guardianship. The judge needs to know what decisions the person can still make with appropriate support — this determines whether full or limited guardianship is appropriate, or whether alternatives would work entirely.

The HIPAA Problem

Here's the catch: to get the physician evaluation, you need the doctor to evaluate your adult child and discuss findings with you. But if your child is already 18, HIPAA prohibits the doctor from sharing any information with you without the patient's written consent.

Solutions, in order of simplicity:

1. Have your child sign a HIPAA release authorizing the physician to discuss their evaluation with you. If they have capacity for this (and most do), this eliminates the barrier immediately.

2. Execute a Healthcare POA that includes records access authority before requesting the evaluation.

3. Request the court order a medical evaluation as part of the petition process. Once the petition is filed, the court can order the evaluation and direct the physician to report findings to the court and attorneys involved.

4. Do not assume a pre-18 authorization carries over. Confirm with the practice whether it has a current written authorization; otherwise obtain one from your adult child or request a court order.

The best approach: have HIPAA releases signed before the 18th birthday, then schedule the guardianship evaluation for shortly after.

How to Prepare the Doctor

Most physicians — even those who have treated your child for years — have never completed guardianship interrogatories. They're unfamiliar with what the probate court needs and may default to unhelpful responses.

Before the appointment, provide:

• A copy of the court's specific interrogatory form (obtained from the probate clerk)
• A written summary of your child's functional capabilities and limitations in plain language
• Specific examples of situations where your child cannot manage independently
• Equally important: examples of decisions your child CAN make with support
• The legal standard they're evaluating against (understanding of delegation, cause-and-effect reasoning)

Ask the doctor to focus on:

• Observed functional behavior, not diagnostic labels
• Specific rather than general statements ("cannot understand the terms of a lease" rather than "has intellectual disability")
• What the person does in the office during the evaluation — communication style, response to questions, ability to express preferences
• Prognosis: is this a stable condition or one likely to improve with support?

What to Avoid in the Evaluation

Too vague: "Patient has Down syndrome and requires a guardian." This tells the judge nothing about capacity or which specific decisions the person cannot make. It provides no basis for a limited appointment.

Too broad: "Patient is completely incapacitated in all domains." Unless your child is genuinely non-communicative and unable to express any preferences whatsoever, this language invites scrutiny from the respondent's court-appointed attorney and makes limited guardianship impossible.

Too old: An evaluation conducted six months ago is outside the relevant window. The evaluation should have been performed within the 30–60 days preceding filing. If your child's doctor completed the form three months ago and you haven't filed yet, you may need a new evaluation or supplemental statement confirming no change in condition.

Too focused on diagnosis: The judge does not need five paragraphs about the genetics of Down syndrome. They need three paragraphs about what this specific person can and cannot do functionally.

County-Specific Form Variations

Missouri counties use different evaluation formats. St. Louis City requires its specific "Physician's Affidavit" (Form 35). Other counties may use general medical interrogatories in various formats. Some courts provide a structured questionnaire; others expect a narrative medical letter under oath.

Always obtain the form from the specific county where you're filing before scheduling the evaluation. Having the doctor redo the evaluation on the correct form wastes time and money.

Timing the Evaluation

The optimal sequence: schedule the physician evaluation so it is performed 30–60 days before your planned filing date. This gives the doctor time to complete the form, gives you time to review it for completeness, and ensures it's fresh when filed. Background checks (due 10 days before the hearing) can be submitted in parallel.

The Missouri Adult Guardianship & Alternatives Guide includes a physician preparation checklist, sample functional capacity questions to discuss with the evaluating doctor, and the complete county-by-county filing timeline to coordinate your evaluation with the rest of the petition process.
