Maryland Code, Courts and Judicial Proceedings § 11-102

(a) A judgment against less than all partners or persons jointly liable on a contract, agreement, instrument, or any other obligation does not extinguish or merge the cause of action against any other partner or person jointly liable but not bound by the judgment.

(b) If the debt is not completely satisfied, any partner or person jointly liable but not bound by the judgment may be sued as if his original liability had been joint and several.
