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)
An acknowledged signature gets a statutory presumption of genuineness, and banks routinely reject unnotarized POAs.
The exception: Louisiana
Louisiana is the only jurisdiction where a general financial POA needs neither a notary nor witnesses to be valid — though 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.
