7 GCA § 12101: Assignment of a Thing in Action Not to Prejudice Defense.

In the case of an assignment of a thing in action, the action by the assignee is without prejudice to any set-off, or other defense existing at the time of, or before notice of, the assignment, but this section does not apply to a negotiable promissory note or bill of exchange, transferred in good faith and upon good consideration, before maturity.
