Choose your form Statutory Power of Attorney form, with Agent's Certification. You do not have to use it. Covers property only, not health care. Ends with a 'Signature and Acknowledgment' (notary) block. An older optional form under the Uniform Statutory Form Power of Attorney Act is still in the statutes; that form is 'legally sufficient' only if your signature is acknowledged before a notary.

Notary or witnesses The Uniform Power of Attorney Act requires only your signature.
