Legal Definitions - attesting witness

An attesting witness is someone who vouches for the authenticity of another person's signature by signing a document that the other person has signed. This means that the witness confirms that the signature on the document is genuine.

For example, when someone signs a will, two attesting witnesses are usually required to sign the document as well. By doing so, they confirm that the signature on the will is indeed the signature of the person who made the will.

Another example is when someone signs a contract. An attesting witness may be required to sign the contract as well to confirm that the signature on the contract is genuine.

Overall, an attesting witness is an important part of ensuring the validity of legal documents and preventing fraud.
