Case Facts: Steven Light bought a $55,050 wedding ring for his wife, Sherri Light, on credit from Royal Jewelers, Inc., a store in Fargo, North Dakota. The receipt granted Royal a security interest in the ring. Later, Royal assigned its interest to GRB Financial
Corp. Steven and GRB signed a modification agreement changing the repayment terms. An attached exhibit listed the items
pledged as security for the modification including the ring. Steven did not separately sign the exhibit.
A year later, Steven died. Royal and GRB filed a suit in North Dakota state court against Sherri, alleging that GRB had a valid
security interest in the ring. Sherri cited UCC 9-203, under which there is an enforceable interest only if "the debtor has
authenticated a security agreement that provides a description of the collateral." Sherri argued that the modification agreement
did not "properly authenticate" the description of the collateral, including the ring, because Steven had not signed the attached
exhibit. The court issued a judgment in GRB's favor. Sherri appealed.
