Signature - Requisites And Validity

When an instrument must be signed, it is ordinarily adequate if the signature is made in any commonly used manner. Variations between the signature and the name appearing in the body of the instrument do not automatically invalidate the instrument.

In the absence of a statutory prohibition, an individual can use any character, symbol, figure, or designation he wishes to adopt as a signature, and if he uses it as a substitute for his name, he is bound by it. For example, if a contract refers to "William Jones" but Jones signs his name "Bill Jones," the contract is still enforceable against him. An individual can also use a fictitious name or the name of a business firm. A signature might also be adequate to validate an instrument even if it is virtually illegible. The entire name does not have to be written, and the inclusion of a middle name is not significant.

An individual satisfies the signing requirement when someone who has been duly authorized to sign for him does so. In the event a statute mandates an instrument be signed in person, the signature must be made in the signer's own hand or at his request and in his presence by another individual.

In a situation where an individual intends to sign as a witness but instead inadvertently signs the instrument in the place where the principal is to sign, the fact that he should have signed as a witness can be shown. Conversely when a signer intends to sign as a principal but instead signs in the place for a witness, that fact can also be shown.
