WHAT AN AFFIDAVIT OF SUPPORT NOTARIZATION ACTUALLY IS
Signing is easy.
Knowing what's actually required is the job.
An affidavit of support is a sponsor's promise to financially support an immigrant — most commonly USCIS Form I-864, or Form I-134 for certain cases. When it's notarized, California treats it as a jurat (Government Code §8202): the sponsor appears in person, takes an oath or affirmation that the statement is true, and signs in front of the notary. The notary verifies the sponsor's ID, watches them sign, and completes the jurat.
Here's the honest part most pages skip: USCIS does not require the I-864 or I-134 to be notarized. The form instructions call for a signature under penalty of perjury — not a notary stamp. So why do people search for this? Because a joint sponsor, an attorney, an agency, or the sponsor themselves has asked for the extra assurance a notarized jurat provides. Notarizing it is completely legitimate when it's requested — we just won't pretend it's a USCIS mandate when it isn't. We handle sponsor affidavits every week for Clayton families dealing with green-card, fiancé-visa, and family-based cases. We come to you, verify ID, administer the oath, and complete the jurat exactly as California requires — so if someone in your process asked for a notarized affidavit of support, it's done right the first time.
We travel to your Clayton home, office, or meeting spot
Sponsor's ID verified and oath administered before signing
Jurat certificate completed exactly to California requirements
Journal entry recorded — your proof the act was done right
Every deed needs a thumbprint
California requires a notary to take the signer's right thumbprint in the journal for every deed, quitclaim, and deed of trust. It's a fraud-prevention step — and it's not optional.
If a notary doesn't ask for your thumbprint on a deed, that's a red flag.
GET IT NOTARIZED
Grant deed or quitclaim?
They both transfer property. They promise very different things — and people mix them up constantly
Grant deed
Grantor hasn't already conveyed the same estate to anyone else (Civil Code § 1113)
Property is free of encumbrances the grantor created
After-acquired title passes automatically to the grantee
Does not warrant the grantor actually owns the property
Quitclaim deed
No implied covenants at all
Transfers only what the grantor holds — possibly nothing
After-acquired title does not pass
Common between spouses, family, divorce and trust transfers
A grant deed is the standard instrument for transferring California property — most Clayton home sales, trust transfers, and family conveyances use one. But it does nothing until it's notarized and recorded. Get the certificate wrong and the Contra Costa Clerk-Recorder in Martinez sends it back, and your transfer waits. Not sure which deed you need? That's a question for your escrow officer, title company, or attorney — we notarize whichever one they prepare.
WHICH ONE IS YOURS?
Six reasons Clayton calls us for a sponsor affidavit
Every situation below can involve a notarized affidavit of support. We handle the notarization for all of them.
I-864 sponsor affidavit
The primary sponsor's Affidavit of Support for a family-based green card. When a joint sponsor, attorney, or agency asks for it notarized, we administer the oath and complete the jurat.
I-134 declaration of support
The Declaration of Financial Support used in fiancé-visa and certain other cases. Sworn before the notary when notarization has been requested.
Joint sponsor affidavit
A second sponsor supplementing the petitioner's income. Joint sponsors often get their affidavit notarized for added assurance — we handle it at their location.
Fiancé (K-1) visa support
Support documents in a fiancé-visa case where the sponsor has been asked to swear to and notarize the affidavit.
Family-based immigration
Spouse, parent, child, or sibling petitions where a sponsor's affidavit of support needs a sworn, notarized signature.
Financial sponsorship letters
Supporting sworn statements of financial support that an attorney, agency, or institution has asked to be notarized alongside the main form.
Not sure whether your form even needs notarizing? Ask your attorney or accredited representative — a notary can't advise on that. If the answer is yes, we're ready.

COMMON QUESTIONS
Frequently asked
Does the I-864 or I-134 actually need to be notarized?
Generally, no. USCIS form instructions require the sponsor to sign under penalty of perjury — they don't require a notary. Many people still get it notarized because a joint sponsor, attorney, agency, or consulate has asked for the added assurance, and notarizing it is perfectly valid. We can't tell you whether your specific case needs it — ask your attorney or accredited representative — but if you've been asked to notarize it, that's exactly what we do.
Can a notary help me fill out or explain my affidavit of support?
No. A notary can't complete the form, calculate your income, choose which form you need, translate immigration documents, or explain what anything means — that would be the unauthorized practice of law and immigration advice. We administer the oath and notarize your signature. For help with the form itself, use a licensed immigration attorney or a DOJ-accredited representative.
What's the difference between the I-864 and I-134?
Both are affidavits of support, but they're used in different situations — broadly, the I-864 is the enforceable Affidavit of Support most family-based green-card cases require, and the I-134 is a Declaration of Financial Support used in certain other cases like some fiancé visas. Which one applies to you is a legal question for your attorney, not a notary. We notarize whichever one you've been asked to have sworn.
Does the sponsor need to be present in person?
Yes. A jurat requires personal appearance, so the sponsor must be physically present for the notary to verify ID, administer the oath, and witness the signature. If there's a joint sponsor, they appear and sign their own affidavit separately — that's the reason we come to you, so appearing in person is simple.
How much does it cost to notarize an affidavit of support in Clayton?
California caps the notary fee per signature (per Government Code limits). For mobile service there's a separate travel/convenience fee based on your location, which we quote up front before we come out — no surprises. Call or book for the exact total.
How fast can I get an affidavit of support notarized in Clayton?
Same-day is usually possible. We typically respond within 30 minutes and can often reach you in Clayton and the surrounding Contra Costa area within the hour for urgent immigration deadlines. Evening and weekend appointments are available.
BEFORE YOUR APPOINTMENT
What to have ready
Four things. Miss one and we can't complete the notarization.
1
Valid government-issued photo ID (the sponsor's)
A current (or recently expired within the period California allows) driver's license, state ID, passport, or other qualifying ID. The name must match the sponsor's name on the affidavit
2
The completed but unsigned affidavit
Fill out the I-864, I-134, or support letter before the appointment — a notary can't complete it for you — but do NOT sign it. A jurat requires you to sign in front of the notary.
3
The sponsor present in person
The person swearing to the affidavit must appear in person with their ID. A joint sponsor signs their own affidavit at their own appointment.
4
The jurat wording on the document
Make sure the page has the "subscribed and sworn to before me" jurat certificate. If it's missing, we can attach a compliant California jurat form.
