The Five Requirements for a Valid Document
Arizona sets out clear rules for this document. The principal must not be incapable at the time of signing. The document must be in writing, dated, and signed.
It must also contain language showing the principal intends to create this type of power of attorney. Finally, it must be notarized or witnessed by at least one adult.
To be valid, a mental health care power of attorney shall: 1. Be executed by a principal who is not incapable, as defined in section 36-3281. 2. Be in writing. 3. Contain language that clearly indicates that the principal intends to create a mental health care power of attorney. 4. Except as provided pursuant to subsection C of this section, be dated and signed or marked by the principal. 5. Be notarized or witnessed in writing by at least one adult.
A.R.S. § 36-3282(A)The witness or notary must confirm they saw the principal sign. They must also confirm the principal appeared to be of sound mind and free from pressure or fraud.
Special Rules for Inpatient Admission
If the document allows inpatient psychiatric admission, Arizona adds extra protection. The principal must separately initial each paragraph that grants this power.
The law also limits who can serve as a witness or notary. That person cannot be the named agent or a care provider working with the principal. If only one witness is used, that witness cannot be a relative or someone who would inherit from the principal.
Having this document in place can spare families from seeking an emergency guardianship. That court process is slower and more costly.
If the principal cannot physically sign, the notary and each witness must verify that the principal approved the document. This rule makes sure physical limits do not block someone from creating it.
