Power of Attorney: Notary and Witness Rules in All 50 States
In 30 states, a financial power of attorney isn't valid without a notary, and 6 states demand two witnesses (5 of them on top of the notary). In the other 20, the statute requires neither. Every rule is cited to the state statute.
Quick answers
Does a power of attorney need to be notarized?
In 30 states, yes — the statute makes notarization a validity or execution requirement for a financial POA. In the other 21 it is not a statutory requirement: where the statute mentions it, a notarized signature is only presumed to be genuine. Banks routinely reject unnotarized POAs, so notarize anyway.
Which states require neither a notary nor witnesses?
20 jurisdictions: Alabama, Arkansas, Colorado, Hawaii, Idaho, Kentucky, Louisiana, Massachusetts, Mississippi, Montana, New Mexico, North Dakota, Ohio, Oklahoma, Oregon, Tennessee, Vermont, Virginia, Wisconsin, Wyoming. There the statute sets no notary or witness requirement for a financial POA, but banks expect a notarized one, so notarize anyway.
Which states require witnesses for a POA?
Connecticut, Florida, Maryland, New York, Pennsylvania, South Carolina require two witnesses, and a few require one. In states offering a "notary OR witnesses" choice, the notary path is counted here and the witness alternative is noted in our per-state sources.
Is this the same for a medical power of attorney?
No — this study covers financial/durable POAs only. Health-care POAs and advance directives follow separate statutes with often stricter witness rules. Check your state’s health-care directive law separately.
What is a statutory form?
Many states publish an official fill-in POA form in the statute itself. Using it maximizes acceptance by banks and agencies. Our state pages follow each state’s statutory form where one exists.

Notary mandatory (30 states)
The statute makes notarization a validity or execution requirement. Tap a state for its fillable POA following that state's rules.
Valid without a notary — but notarize anyway (21 states)
The statute does not make notarization a validity requirement — where it mentions it, an acknowledged signature is only presumed genuine. Banks routinely reject unnotarized POAs. Louisiana, which sets no required form at all, is covered in its own section below the table.
Louisiana: no required form
Louisiana's Civil Code subjects a procuration (its power of attorney) to the rules of mandate (art. 2988), and a mandate “is not required to be in any particular form” — except that when the law prescribes a form for the act the agent will carry out, the mandate must be in that form (La. Civ. Code art. 2993). Notarizing remains wise for bank acceptance there too.
How to read these rules (methodology)
Scope: financial/durable POA only — health-care POAs follow separate, often stricter statutes. "Notary OR witnesses" states are counted on the notary path, with the witness alternative documented in our per-state sources. Rules as of 2026; the statute linked on each row is authoritative. This is a comparison, not legal advice.
