Frequently Asked Questions

Can a family member notarize my signature?

Generally no. Notaries cannot notarize documents in which they have a personal interest. Family member documents typically create conflicts of interest.

Do both parties need to be present?

Not usually. Each party can have their signature notarized separately, at different times and locations.

Can a notary refuse to notarize?

Yes, if:

• Cannot verify identity
• Signer appears incompetent
• Signer seems under duress
• Document is incomplete
• Notary has conflict of interest

Is a notarized document legally binding?

Notarization doesn't make a document legal—it authenticates the signatures. The document's enforceability depends on its content and formation.

How long is notarization valid?

The notarization itself doesn't expire. The notary's commission has an expiration date, but notarizations performed while commissioned remain valid.

Can I notarize a document in a different language?

Notaries can notarize documents in any language, but they must be able to communicate with the signer and understand the type of notarization requested.
