ALLONGE (from Fr. allonger, 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 .
