Missouri's Durable Power of Attorney Law provides default-durable POAs

Missouri Revised Statutes — Durable Power of Attorney Law

Mo. Rev. Stat. § 404.700

What the rule says

Missouri's Durable Power of Attorney Law, codified at Mo. Rev. Stat. § 404.700 et seq., provides Missouri with a comprehensive POA framework.

Default durability

A Missouri POA is durable by default — the agent's authority survives the principal's incapacity unless the document expressly states otherwise.

Specific powers

Under Mo. Rev. Stat. § 404.710, certain powers require express authorization in the POA:

- Making a gift - Creating, amending, modifying, revoking, or terminating an inter vivos trust - Creating or changing rights of survivorship - Creating or changing a beneficiary designation - Disclaiming property

Third-party acceptance

Missouri law provides protections and obligations for third parties accepting properly executed POAs.

Execution requirements

A valid Missouri POA must be:

- Signed by the principal - Acknowledged before a notary public

Healthcare power of attorney is separate

Missouri separates property and healthcare frameworks. Healthcare decisions require a separate Missouri Durable Power of Attorney for Health Care under Mo. Rev. Stat. § 404.800 et seq.

What happens without a POA

If a Missouri resident becomes incapacitated without an executed durable POA, the family must seek conservatorship or guardianship under Mo. Rev. Stat. § 475.010 et seq.

What you can do about it

For Missouri residents:

- Execute a durable POA. - Acknowledge before a notary. - Specifically enumerate hot powers if needed. - Designate a successor agent. - Coordinate with the Healthcare POA. - Update older POAs.

Who this affects most

Missouri's POA framework is most consequential for Missouri adults without executed POAs and households where significant agent authority is needed.
