Negotiable Instruments Act Section 15 — Indorsement
CHAPTER II OF NOTES, BILLSAND CHEQUES
General
Summary
When the person who makes a negotiable instrument, or the person who currently holds it, signs it—not in their role as the maker, but for the purpose of passing it on to someone else—that signing is called an endorsement. The signature can be on the back or front of the instrument, or on a separate piece of paper attached to it. It can also be on a stamped paper that is meant to be turned into a negotiable instrument later. The person who signs in this way is called the “indorser.”
Official Text
When the maker or holder of a negotiable instrument signs the same, otherwise than as such maker, for the purpose of negotiation, on the back or face thereof or on a slip of paper annexed thereto, or so signs for the same purpose a stamped paper intended to be completed as a negotiable instrument, he is said to indorse the same, and is called the “indorser”.
