Missouri Power of Attorney Limits: What It Does Not Cover for a Minor Child

A power of attorney under RSMo 475.602 gives a relative caregiver broad authority over a child's school, medical, and daily life. But it has hard boundaries set by statute, and running into one of them at a hospital intake desk or a court proceeding is not the time to learn about them.

The Four Statutory Exclusions

RSMo 475.604(6) explicitly lists four things a POA cannot delegate, regardless of how broadly the document is drafted:

1. Consent to the child's marriage
2. Consent to the child's adoption
3. Consent to the performance or inducement of an abortion
4. Consent to the termination of parental rights

These exclusions are absolute. Even a general delegation that purports to grant "all powers regarding the care, custody, and property of the child" cannot override them. A parent retains sole authority over these decisions.

The Missouri Court of Appeals addressed the boundary of the fourth exclusion in In the Interest of A.J.C. (WD86706, August 2024). The court held that while an attorney-in-fact cannot consent to termination of parental rights on a parent's behalf, they can independently petition the juvenile court to terminate parental rights based on statutory grounds such as abandonment or severe neglect. The distinction is between signing a voluntary surrender (prohibited) and initiating a legal proceeding (permitted).

Inpatient Psychiatric Admission

This is the limitation that catches the most kinship caregivers off guard. Under RSMo 632.110, voluntary admission of a minor to a mental health facility requires consent from a biological parent or court-appointed legal guardian. An attorney-in-fact under a POA cannot authorize it. Neither can a relative holding a Caregiver Affidavit under RSMo 431.058.

If a child in your care is in acute psychiatric crisis and needs inpatient treatment, your options are:

• Emergency evaluation — any adult standing in loco parentis can consent to emergency medical care under RSMo 431.061, which includes emergency psychiatric evaluation
• Department of Mental Health or juvenile court support — when parental consent is unavailable, seek assistance through these channels about available options
• Contact the biological parent — if the parent is reachable and willing, coordinate consent directly with the facility

For non-emergency outpatient therapy and counseling, a POA or caregiver affidavit is sufficient. The restriction applies specifically to formal inpatient psychiatric admission.

Medical Decisions Where the Parent Overrides You

For decisions made under a Relative Caregiver Affidavit, RSMo 431.058.3 provides that a parent's decision supersedes a conflicting caregiver decision unless the parent's decision poses an immediate threat to the child's life, health, or safety. A POA does not transfer custody and remains revocable by the parent.

In practice, if a parent gives different instructions about the child's care, the caregiver should raise the conflict directly with the provider. The POA does not give the caregiver authority over the parent; it delegates authority while the parent retains legal rights and can revoke the delegation.

What a POA Does Not Establish

Beyond the explicit exclusions, a POA under RSMo 475.602 does not:

• Transfer legal custody — the parent remains the legal custodian
• Establish child support obligations on the caregiver
• Create eligibility for foster care payments or subsidies (those require Children's Division involvement)
• Override an existing court order — if a family court or juvenile court decree already governs the child's placement, a private POA that conflicts with it has no legal effect
• Establish residency for school enrollment — DESE policy clarifies that a POA confers authority to act on behalf of a student but does not establish domicile

When You Hit a Limit

If you find yourself consistently running into situations where the POA is not enough — insurance enrollment denials, inpatient treatment barriers, institutions demanding court orders — it may be time to consider guardianship. A court order can provide broader authority, but no document guarantees institutional acceptance.
