Attestation is a kind of testimony or confirmation. It is customary to sign a deed, make a will or sign other written documents in the presence of a witness who also signs the document to attest to its contents and the authenticity of the party's signature.

Attestation is the act of witnessing the signing of a formal document and then also signing it to verify that it was properly signed by those bound by its contents. Attestation is a legal acknowledgment of the authenticity of a document and a verification that proper processes were followed.

Include your relationship to the person and any applicable certifications you have. For example, if you're writing an attestation letter for a former employee, you might begin by describing your job title in the company and how long you've been working there.

The certifier will then write or stamp the copy with the words: “Certified to be a true copy of the original seen by me.” They will sign and date the copy, and write or stamp their: name. personal or professional address, and. qualification as an authorised certifier.

Self-attestation simply requires you to place your signature on a photocopy of the document you want to certify. After you have a made a clean copy of your document, write a statement on it such as: “True copy” or “Self-attested copy”. Then place your signature directly under it.

In essence, they're a form completed by a third party (i.e. someone not related in any way to those signing the original document). An attestation form can be useful in any situation where a legal document needs supporting evidence to prove it's authentic and legally valid.

An example of a standard attestation clause: The testator signed in the presence of both of us being present at the same time, and we attested his/her signature in the presence of him/her and of each other.
