Attestation
Definition
Attestation is the act of witnessing the signing of a document and confirming its authenticity by adding one's own signature as a witness. An attesting witness observes the signing party execute the document and then signs to verify that the signature is genuine and was made voluntarily. Attestation adds a layer of authenticity and can be legally required for certain documents such as wills, deeds, and powers of attorney. The attesting witness does not need to know the contents of the document — they are only confirming that they saw the person sign it.
In Practice
A business owner executes a commercial lease in the presence of two witnesses, as required by state law for real property agreements. Both witnesses watch the owner sign, then add their own signatures in the attestation block along with their printed names and addresses. Months later, when the other party claims the signature was forged, the two attesting witnesses can testify in court that they personally observed the signing.
Example Clause
IN WITNESS WHEREOF, the Parties have executed this Agreement as of the date first written above, in the presence of the undersigned witnesses. ATTESTED BY: Witness 1: _______________ (Signature) Name: _______________ Date: _______________ Witness 2: _______________ (Signature) Name: _______________ Date: _______________

Frequently asked questions about attestation
Attestation is witnessing a signature — any competent adult can attest. Notarization is a formal verification by a licensed notary public who verifies the signer's identity (typically through government ID), confirms they're signing voluntarily, and applies an official notary seal. Notarization carries more legal weight than attestation because the notary is a state-authorized official. Some documents require both witnesses and notarization.
