Legal Requirements and Procedures for Proof of Execution by a Subscribing Witness
Published July 16, 2024 · Updated May 26, 2026
Normally, the person signing a document appears before you in person. But what happens when the signer cannot come to you? In some states, a subscribing witness can appear instead, swearing that they watched the principal sign. This is called proof of execution by a subscribing witness, and the rules around it are strict.
Subscribing Witnesses Defined
A subscribing witness is someone who watched the principal (the person whose name is on the document) sign it, and then brings the document to the notary to attest to that fact. The witness is “subscribing” (attesting) to the execution of the document.
This is different from a credible witness, who vouches for a signer’s identity when the signer has no ID. A subscribing witness is vouching for the act of signing itself.
When Proof of Execution Applies
This procedure is only for acknowledgments, not jurats. The signer must have already signed the document in front of the witness. The witness then brings the signed document to you.
Not all states allow proof of execution by subscribing witness. And the states that do allow it often restrict which documents qualify. For example, many states prohibit using this method for real estate deeds or conveyances.
State Rules
California
California allows proof of execution by a subscribing witness under California Civil Code Section 1191. The witness must either be personally known to the notary or be proved by a credible witness who is personally known to the notary. California prohibits this method for real property documents, powers of attorney, or any document that requires recording. For practical purposes, this limits it to relatively few notarizations.
Florida
Florida allows proof of execution under Florida Statute 117.05(13). The subscribing witness must personally appear before the notary, take an oath, and sign an affidavit stating they saw the principal sign. The notary must verify the witness’s identity with a government-issued ID.
Texas
Texas allows proof of execution under Texas Civil Practice and Remedies Code Section 121.004. The subscribing witness must appear before the notary and make an oath that they saw the principal sign. Texas restricts this method for certain real estate documents.
States That Do Not Allow It
Some states do not provide for proof of execution by subscribing witness at all. Check your state’s notary handbook or Secretary of State website before attempting this type of notarization. If your state does not explicitly authorize it, do not do it.
Step-by-Step Process
- The principal signs the document in front of the subscribing witness (not in front of you).
- The subscribing witness brings the signed document to you.
- You verify the subscribing witness’s identity using a government-issued photo ID (or personal knowledge, if your state allows).
- You administer an oath to the subscribing witness: “Do you swear or affirm that you personally saw [principal’s name] sign this document?”
- The subscribing witness signs the notarial certificate (or an attached affidavit).
- You complete the notarial certificate, sign, and apply your seal.
- Record the notarization in your journal, noting that it was proof of execution by subscribing witness.
What Goes Wrong
- Using it for the wrong document type. If your state prohibits this method for deeds or real estate documents and you do it anyway, the document could be rejected by the county recorder.
- The witness does not actually know the signer. If the witness was hired off the internet or is a stranger to the principal, the notarization is on shaky ground. The witness should be someone with a genuine connection to the signer.
- Not recording it properly. Your journal entry should clearly state that this was a proof of execution by subscribing witness, include the witness’s name and ID details, and note that the principal did not appear before you.
Frequently Asked Questions
Can I charge extra for a proof of execution?
Charge your state’s standard notarization fee. Some notaries add a fee for the additional time and documentation required, but check whether your state limits what you can charge.
Does the subscribing witness sign the document itself?
The witness signs the notarial certificate or an attached affidavit, not the main document (unless the document itself has a witness signature line). The notarial certificate is the witness’s formal attestation.
Can I use this for a loan signing?
Generally no. Lenders and title companies require the borrower to appear in person before the notary. If the borrower cannot appear, the signing gets rescheduled. Check with the hiring company before attempting proof of execution for a loan document.
