Irregular Indorsement Law and Legal Definition

Irregular indorsement refers to an indorsement signed by a person who does not hold the title. Hence, the person is neither a holder nor a transferor of the instrument. An irregular indorser is also known as accommodation party. An irregular indorsement is also known as analomous indorsement or full indorsement.

The following is an example of a case law defining irregular indorsement:

An irregular indorsement is an independent contract from that of the maker and is governed by its own peculiar incidents.[Spragins v. McCaleb, 237 Ala. 658 (Ala. 1939)]
