In most states a notary can serve as a document witness and the notary on the same signing, and you can charge separately for the witness role since fee caps only govern notarial acts. The exceptions cluster around wills, self-proving affidavits, and any document in which you hold a financial interest. This guide covers when to accept the double role, when to decline it, and what to charge.

The Role of a Witness

A document witness watches someone sign a document and then signs their own name to confirm they saw it happen. The witness is not vouching for the content of the document. They are confirming that the person signing appeared to be who they claimed to be, seemed to be acting willingly, and actually signed in their presence.

Documents that commonly require witnesses include:

• Wills (most states require two witnesses)
• Powers of attorney (many states require one or two witnesses)
• Real estate deeds (some states require witnesses)
• Living wills and healthcare directives
• Certain contracts and agreements

The Difference Between Notarizing and Witnessing

These are two separate acts. When you notarize a document, you verify identity, administer an oath or take an acknowledgment, and complete a notarial certificate with your seal. When you witness a document, you simply watch the person sign and then sign your own name as a witness.

The two roles are not interchangeable. Witnessing a signature does not make you a notary for that document. Notarizing a document does not make you a witness (unless the document specifically calls for a witness and you sign as one).

When Notaries Can Be Witnesses

In most states, a notary can serve as both a notary and a witness on the same document. There is no inherent conflict because the two roles serve different purposes. As a notary, you verify identity and complete the notarial certificate. As a witness, you confirm you saw the signing happen.

However, the same conflict-of-interest rules apply to both roles. You cannot serve as a witness (or a notary) for a document in which you have a direct financial or beneficial interest. If you are named in the will, stand to inherit property, or are a party to the contract, you cannot serve as either witness or notary.

When a Notary Cannot Serve as a Witness

• Wills in some states: Several states restrict who can witness a will. Some disqualify notaries who are also beneficiaries. A few states prohibit notaries from witnessing wills entirely or require witnesses who are not notaries on the same document. Check your state law.
• Self-proving affidavits: In some states, the witnesses to a will and the notary to the self-proving affidavit must be different people. You may not be able to serve as both.
• Documents where you have a financial interest: If you are the grantee on a deed, the beneficiary of a trust, or a party to the agreement, you cannot be a witness or a notary on that document.
• State-specific restrictions: A handful of states have specific prohibitions. South Carolina, for example, has rules about notaries and witnesses on certain estate documents.

Practical Tips

• If a signer asks you to witness and notarize, confirm your state allows it before agreeing.
• Charge separately for each role if your state allows it. Notarization has a state-regulated fee. Witnessing does not, so you can set your own rate or include it in your mobile fee.
• Record both acts in your notary journal: the notarization and the witnessing.
• Make sure the document has separate signature lines for the notary and the witness. If the document only has one line for you, clarify which role you are filling.
• If you are unsure whether your state allows dual roles, refuse the witnessing and only perform the notarization. The signer can find another witness.
