California requires a thumbprint in the journal for certain instruments — deeds, quitclaim deeds, deeds of trust and powers of attorney — because a print is the one element of the record that cannot be forged or borrowed. But the requirement is directed at obtaining the signer's own print, and a signer who physically cannot provide one is not thereby barred from having a document notarized. The statute anticipates this: where the signer cannot affix a print, the notary records that fact in the journal along with an explanation of the reason. That entry becomes part of the record and preserves the audit trail's integrity by documenting why the usual element is absent, rather than leaving an unexplained gap. What is never acceptable is a substitute print from anyone else, which would introduce a false element into the record — worse than an explained absence. Nor is a court order needed; the notary handles it within the act.
