(a) After a cause of action has accrued on any obligation on which there is more than one obligor, any act, admission, or acknowledgment by any party to such obligation or guarantor thereof, which removes the bar of the statute of limitations or causes the statute to begin running anew, has such effect only as to the party doing such act or making such admission or acknowledgment, and shall not renew, extend or in any manner impose liability of any kind against other parties to such obligation who have not authorized or ratified the same.
(b) Nothing in this section shall be construed as applying to or affecting rights or obligations of partnerships or individual members thereof, due to acts, admissions or acknowledgments of any one partner but rights as between partners shall be governed by G.S. 59-39.1. (C.C.P., s. 50; Code, s. 171; Rev., s. 372; C.S., s. 417; 1953, c. 1076, s. 1.)
