Witnessing a signature is the process of having an individual physically present when another person signs a document. This process ensures that the signer’s identity has been verified and confirms that they are who they say they are. The witness usually provides their name, address, and contact details so that the validity of the signature can be independently confirmed if necessary. Witnessing a signature acts as a safeguard for both the signer and the company receiving the document and helps to ensure accuracy and compliance with legal requirements.
