What a notary can't do

California law has strict rules about notary conduct. Knowing these ahead of time saves you a trip.

  • California law prohibits notaries from giving legal advice or preparing documents.
  • We don't pre-notarize — you must sign in front of us, never before.
  • We don't notarize for signers who appear impaired or unable to communicate in English or a language we can translate.
  • We don't notarize incomplete documents or documents with blanks.
  • On loan signings we only notarize — we do not review, explain, or advise on the content of loan documents. Questions about your loan terms should go to your lender, escrow officer, or attorney.

Frequently asked

Direct answers to what customers ask us most.

How much does a notary cost at Mailbox Plus?

$15 per signature. California law caps what notaries can charge per notarial act, and we charge the standard rate. For documents with multiple signatures or signers, the fee multiplies — for example, a trust document with 4 signatures is $60. Loan signings with many pages are priced the same per-signature way.

Do I need an appointment?

For one or two documents, walk in during store hours (Mon–Sat, 10am–6pm). For three or more documents, or for loan-signing packets, we recommend calling ahead to schedule so you don't wait behind walk-in traffic. Call (408) 372-8689.

What ID do I need to bring?

One current, unexpired government-issued photo ID: California driver's license or ID card, US passport, military ID, permanent resident card, or a driver's license/passport from another US state or foreign country that includes a photo, signature, and physical description. The name on your ID must match the name on the document.

Can a notary give me legal advice?

No. California law prohibits notaries from giving legal advice, explaining legal documents, or helping you decide what to sign. Our role is strictly to verify your identity, witness your signature, and apply the official seal. If you need advice on the content of a document, consult an attorney.

Can I get a document notarized if it's already signed?

No. California requires the signer to appear in person in front of the notary and sign during the notarial act. If you've already signed, the notary will ask you to sign again in their presence on a fresh document.

Do you notarize wills?

Yes, we regularly notarize estate planning documents including pour-over wills, trust documents, and healthcare directives. Note that in California, a will itself is typically self-proved with two witnesses rather than a notary, but the accompanying trust and directive documents do require notarization.

Can you notarize for non-English speakers?

The notary must be able to communicate directly with the signer to verify their identity and willingness to sign. We can notarize documents written in any language (we don't need to read them), but we need to verbally confirm understanding with the signer. A translator can't answer for them.

Can you mail out my notarized document for me?

Yes. We're also a FedEx Authorized ShipCenter and USPS retailer, so once a document is notarized we can ship it domestically or internationally the same day. Overnight FedEx is available for time-sensitive documents.

Are you open for notary services on Saturday or Sunday?

We're open for walk-in notary on Saturdays (10am–6pm), same as weekdays. Sundays we're closed. If you need weekend notary service specifically, Saturday is your day. For urgent Sunday needs, we recommend booking a mobile notary in advance — ask us for referrals.

Do you do loan signings for real estate or refinance?

Yes, with one important clarification: we provide notary services only. We witness your signatures, verify your ID, and apply the official seal on pages that require notarization — but we do not act as a certified signing agent (NSA) and we do not review, explain, or advise on the content of your loan documents. If you have questions about the terms of your loan, please contact your lender, escrow officer, or an attorney before your appointment. We regularly notarize packets for purchase closings, refinances, HELOCs, and reverse mortgages. Please call ahead to schedule so we can set aside focused time — bring the full packet, a current government-issued photo ID, and payment for each signature that requires notarization.

Do you offer mobile notary services?

We don't travel to your location — our notaries work out of our San Jose store only. If you need a mobile notary (one who comes to your home, hospital, or office), we can refer you to trusted mobile notaries in the San Jose area. For in-store visits, we're fast — most single-document notarizations take under 10 minutes.
