Any such notice to the holder or owner of the obligation as is authorized by G.S. 26-7 may be given at or subsequent to the time such obligation is due or at or subsequent to the termination of a period of extension.(c) The failure of any co-surety, co-indorser or co-guarantor to join in or adopt a notice to the holder or owner of the obligation as authorized by subsection (b) of G.S. 26-7 does not prevent such co-surety, co-indorser or co-guarantor from giving a separate notice as authorized by subsection (a) of G.S. 26-7. 1868-9, c. 232, s. 2; Code, s. 2098; Rev., s. 2847; C.S., s. 3969; 1951, c. 763, s. 3.
