Signing Requirements
Though state statutes do not mention signing requirements, it is common practice for at least the principal to sign the document.
Having the document signed by two witnesses or acknowledged by a notary public is often recommended if the document’s validity or the attorney-in-fact’s powers are questioned.
Legal Definition
“This power of attorney shall not be affected by subsequent disability or incapacity of the principal,” or “This power of attorney shall become effective upon the disability or incapacity of the principal.”[1]
