allonge  (a-lawnzh).  A  slip  of  paper  sometimes  attached  to  a  negotiable  instrument  for  the

purpose  of receiving further indorsements when the  original  paper is filled with indorsements. •

Former UCC § 3-202 required that indorsements be made on the instrument unless there was no

space — and only then could an allonge be used. Current § 3-204(a) eliminates that requirement

and provides that “a paper affixed to the instrument is part of the instrument.” The UCC comment

makes it clear that the allonge is valid even if space is available on the instrument. [Cases: Bills
