13 GCA § 3306: Rights of One Not Holder in Due Course.

Unless he has the rights of a holder in due course any person takes the instrument subject to

(1) All valid claims to it on the part of any person; and

(2) All defenses of any party which would be available in an action on a simple contract; and

(3) The defenses of want or failure of consideration (Section 3408), nonperformance of any condition precedent, nondelivery, or delivery for a special purpose; and

(4) The defense that he or a person through whom he holds the instrument acquired it by theft, or that payment or satisfaction to such holder would be inconsistent with the terms of a restrictive indorsement. The claim of any third person to the instrument is not otherwise available as a defense to any party liable thereon unless the third person himself defends the action for such party.
