ALLONGE (from Fr. alloinger, to draw out), a slip of paper affixed to a negotiable instrument, as a bill of exchange, for the purpose of receiving additional indorsements for which there may not be sufficient space on the bill itself. An indorsement written on the allonge is deemed to be written on the bill itself. An allonge is more usually met with in those countries where the Code Napoleon is in force, as the code requires every indorsement to express the consideration. Under English law, as the simple signature of the indorser on the bill, without additional words, is sufficient to operate as a negotiation, an allonge is seldom necessary.
