A negotiable instrument must be written and signed.
Rights secured through oral promises may be assignable but never negotiable, no matter what words are used to express them. The term "writing" includes "print." The writing may be in lead or ink, though it is hardly necessary to say that the latter is preferable.
So it must be signed. It is a rule that no party can be liable on a negotiable instrument as maker, drawer, or acceptor unless he has signed it, by himself or his duly authorized agent. The name signed, however, may be an assumed one. Thus if a note should be signed by the namee of a partnership, containing, say fifty partners, thus "General Manufacturing Company, by John Jones," all the partners would be individually liable thereon, for they would all be named in this fictitious name; assuming, of course, that the person signing the note had real or apparent authority to bind the firm, as stated. A signature should never be typewritten or printed.
