What to know
Issuing office: None — privately drafted; a California notary public notarizes the signatures. Notaries are available at banks, shipping/UPS stores, law offices, and via mobile notaries. CA SOS Notary Public Section: (916) 653-3595. Notarized route (steps): Finalize the executed NDA (all signature blocks complete). Each signatory whose signature needs authentication signs (or acknowledges their signature) in the physical presence of a California notary, with acceptable ID. The notary completes a current California acknowledgment for each signature, attaches the certificate(s), and affixes the seal. Confirm legibility and that the commission number/expiration appear. Who can sign it: The parties (or their authorized officers if a company is a party). Required forms: None statewide — the parties’ own NDA plus California notary acknowledgment wording. Cost + timeline for THIS step.
Frequently asked questions
Does an NDA have to be notarized?
Not to be valid — notarization is added only so the document can be apostilled for use abroad.
Do both parties need to be notarized?
Only those whose signatures the foreign authority needs authenticated — but each one notarized must personally appear before the California notary.
Parties in different states — one apostille?
No. California authenticates only California notaries; an out-of-state signer apostilles through their own state.
Is there a government fee?
No — it is a private contract; the cost is the notary fee plus the apostille.
