If A sells to B an obligation of C which A owns, and as part of the sale A guarantees the obligation such promise is not within the statute of frauds.1 Thus, if A in payment of certain property sold to him by B assigns to B a certificate of deposit issued by a bank C, and also gives a check on such bank, A's promise to B to pay such certificate of deposit and check if C does not pay by a certain time is not within the statute.2 The same rule applies where A sells to B, C's property left with A to sell and apply the proceeds to A's debt, and A agrees to protect B against a pending replevin suit brought by X.3
