A more thorough explanation: “Sign manual” refers to a handwritten signature or mark made by an individual on a document, typically to signify their approval, agreement, or authentication. In legal terms, a sign manual is a physical signature made by a person using their own hand, as opposed to a digital or electronic signature.
Example: The CEO signed the contract with a sign manual, indicating his approval and agreement to the terms.
