46.     Signature of documents by agent.

At common law the general rule1 is that a person sufficiently signs a document if it is signed in his name and with his authority by someone else; and in such case the agent's signature is treated as that of his principal2. Although it is usual and the better practice to indicate on the document that the signature the agent has written is not that of the principal, omission so to do, though misleading and undesirable, does not necessarily invalidate the document3.
