How Long Does a Notary Commission Last, and Why It Matters to You

Notary commissions aren’t permanent — they run for a fixed term set by state law and then have to be renewed. Most clients never think about this, and they don’t need to, but understanding it explains a few things that occasionally come up, especially with older documents.

Why the term limit exists

Requiring periodic renewal keeps a notary’s bond, background, and contact information current with the state, and it gives the commissioning authority a regular checkpoint rather than a one-time approval that’s never revisited. It’s the same logic behind renewing a driver’s license or a professional certification — not a punishment, just ordinary upkeep for a role that carries legal weight.

What happens when a commission expires

  • The notary can no longer legally perform new notarizations until they renew
  • Notarizations performed while the commission was active remain valid — an expiration doesn’t retroactively undo past work
  • A notary who continues notarizing after expiration is acting outside their authority, which is a real problem if it ever happens (it shouldn’t, with a notary who’s keeping their credentials current)

Why this occasionally matters to you

If you ever need to verify an old notarization — say, for a document that’s being challenged years later — confirming the notary’s commission was active on the date in question is part of establishing that the notarization was valid. This is one more reason careful journal-keeping matters: it ties a specific notarization to a specific date, which can then be checked against commission records if it’s ever necessary.

You’re never responsible for checking a notary’s commission status yourself — that’s on us. It’s just useful context for why notaries take renewal seriously.

How to verify a notary’s commission is current

Both Kansas and Missouri maintain public look-up tools through their Secretary of State’s office where you can confirm a notary’s commission is active. I cover exactly how to use them in a separate, practical walkthrough if you’d like to check for yourself before an appointment.
