Thumbprint Requirements

In a notorious deed fraud case, a criminal impersonated a homeowner using a fake driver's license. The notary verified the ID, completed the journal entry, and performed what appeared to be a proper notarization. But when investigators later examined the case, the thumbprint in the notary's journal didn't match the real homeowner—providing definitive proof that an imposter had signed the deed. The thumbprint became the key evidence that exposed the fraud.

This is why California requires thumbprints for high-value documents: thumbprints are nearly impossible to fake, and they provide undeniable evidence of who was actually present.

Why Thumbprints Matter

AdvantageExplanation
Unique identificationNo two people have the same fingerprints
Cannot be forgedUnlike signatures, thumbprints can't be practiced or copied
Forensic evidenceCan be matched to a specific person by law enforcement
Fraud deterrentCriminals know thumbprints identify them

When Thumbprints Are REQUIRED

A thumbprint is MANDATORY in your journal for these document types:

Document TypeWhy High Risk
Grant deedsTransfers real property ownership
Quitclaim deedsReleases claims to real property
Deeds of trustSecures mortgage loans
Other trust deedsAny trust affecting real property
Powers of attorneyAuthorizes others to act on signer's behalf

Key Point: Real estate documents and powers of attorney are primary targets for fraud because they transfer high-value assets or grant significant authority. The thumbprint provides an additional layer of protection.

What "Affecting Real Property" Means

Any document that affects real property = thumbprint required:

Examples Requiring ThumbprintExamples NOT Requiring Thumbprint
Grant deedBusiness contract
Quitclaim deedAffidavit (general)
Deed of trustCorporate resolution
ReconveyanceImmigration forms
Subdivision mapSchool documents

Thumbprint Procedure

Standard Procedure

StepAction
1Request the signer's RIGHT thumbprint
2Apply ink to the right thumb (inkpad or inkless pad)
3Press thumb firmly in the designated journal space
4Roll slightly to capture good impression
5Allow to dry before closing the journal

If Right Thumb Is Unavailable

If the signer cannot provide a right thumbprint (injury, amputation, bandage, etc.):

StepAction
1Use any available finger
2Note in the journal which finger was used
3Examples: "Left index finger" or "Right index finger"

Key Point: The journal must document which alternative finger was used if not the right thumb.

Thumbprint Refusals

This is a heavily tested topic. If a signer refuses to provide a thumbprint for a required document:

SituationNotary's Response
Signer refuses thumbprint for deedREFUSE to notarize
Signer refuses thumbprint for POAREFUSE to notarize
Signer says "I don't like ink"Explain it's legally required
Signer claims religious objectionStill cannot proceed without thumbprint

Critical Point: There is NO EXCEPTION for refusal. If the document requires a thumbprint and the signer won't provide one, the notarization CANNOT proceed.

How to Handle Refusals

  1. Politely explain the thumbprint is required by California law
  2. Explain it's for their protection against fraud
  3. If they still refuse, you must decline the notarization
  4. Document the refusal in your notes (not in the journal itself)

When Thumbprints Are Optional

For documents NOT on the required list, thumbprints are optional but recommended:

Document TypeThumbprint Required?Recommendation
AffidavitNoRecommended
General contractNoRecommended
Corporate documentsNoRecommended
Immigration formsNoOptional
Consent formsNoOptional

Best Practice: Many experienced notaries collect thumbprints for ALL notarizations—it's additional protection even when not legally required.

  • Which documents require thumbprint: Deeds + POAs (real property and authorization documents)
  • Which thumb: Right thumb is default
  • If unavailable: Use another finger AND note which one
  • Refusal to provide: MUST refuse to notarize—no exceptions
  • Where recorded: In the journal (not on the document)
