Commonwealth Consolidated Acts Commonwealth Consolidated Acts(1) Where a person signs a bill as drawer, indorser, or acceptor, and adds words to his or her signature, indicating that he or she signs for or on behalf of a principal, or in a representative character, he or she is not personally liable thereon; but the mere addition to his or her signature of words describing him or her as an agent, or as filling a representative character, does not exempt him or her from personal liability.
(2) In determining whether a signature on a bill is that of the principal or that of the agent by whose hand it is written, the construction most favourable to the validity of the instrument shall be adopted.
