The Missouri Power of Attorney Forms outline the ways in an individual, of their own volition, grants another party the right to manage one or more affairs on their behalf.

What is a Missouri Power of Attorney?

Missouri Power of Attorney is a contract that allows an individual to elect another individual or an entity to transact one or several affairs in their stead. Anyone who is considering drafting a POA in the state of Missouri should be aware that state law refers to the parties of these contracts in a dissimilar way to most other states. That is, unlike most other states, Missouri state law refers to the party who will assist the Principal as the “Attorney in Fact”. Furthermore, in a Medical Power of Attorney, the individual who brings about the POA is referred to as the “Patient” (however, for non-medical POA forms, this individual is referred to using the usual term, the “Principal”).

  • Missouri Power of Attorney Laws Title XXVI, Chapter 404 (§ 404.700 to § 404.737), “Durable Power of Attorney” and Title XXVI, Chapter 404 (§ 404.800 to § 404.872) “Durable Power of Attorney for Health Care Act”
  • State Definition of a Durable Power of Attorney (§ 404.703(4)) – “a written power of attorney in which the authority of the attorney in fact does not terminate in the event the principal becomes disabled or incapacitated or in the event of later uncertainty as to whether the principal is dead or alive and which complies with subsection 1 of section 404.705 or is durable under the laws of any of the following places: (a)  The law of the place where executed; (b)  The law of the place of the residence of the principal when executed; or (c)  The law of a place designated in the written power of attorney if that place has a reasonable relationship to the purpose of the instrument.”
  • Signing Requirements
    • General / Durable Power of Attorney (Art. 2993 & ) – No specific signing requirements are provided by state law. Although not mandated by law, it is in the best interests of all parties that a POA is signed by the Principal before a Notary Public and two (2) witnesses.
    • Durable Power of Attorney for Health Care (§ 404.825) – No specific signing requirements are stated. Nevertheless, for the terms of the agreement to commence, it is necessary for two (2) licensed physicians to examine and subsequently certify the Principal’s state of incapacity. That is, “Unless the patient expressly authorizes otherwise in the power of attorney.”

When is it Effective?

State law does not detail any signing requirements regarding the necessity of a Notary Public or witnesses. Despite the lack of mandated requirements in this regard, the Principal should consider arranging for a Notary Public to be present, or alternatively, two (2) witnesses.

For a Durable POA to be put into effect, the Principal must ensure that one of the provisions detailed by § 404.705 is stated in the document in a substantial manner.

For a Durable POA for conveyances of real estate to be put into effect, § 404.705 states that it must be “subscribed by the principal, and dated and acknowledged in the manner prescribed by law for conveyances of real estate.”

While no signing requirements are specified for a Durable POA for Health Care to commence, state law does specify one other requirement that must be fulfilled for it to commence. Namely, § 404.825 states that unless the Patient (the Principal) “expressly authorizes otherwise in the power of attorney”, two (2) licensed physicians must certify, based on an examination of the Patient, that the Patient is “incapacitated and will continue to be incapacitated for the period of time during which treatment decisions will be required and the powers and duties shall cease upon certification that the patient is no longer incapacitated.”
