A. All parties to a joint obligation, including negotiable paper and partnership debts, shall be severally liable also for the full amount of such obligations. An action may be brought against such parties jointly or separately, joining one or more, and judgment may be given in each such action without barring an action against any party to the obligation not included in the judgment, and without releasing any party against whom the action was not brought.
B. The court may, upon its own motion or upon the application of any interested party, require that the plaintiff bring in as defendants all parties jointly liable on the obligation upon which the action is brought, in which event any subsequent judgment shall be for the amount unsatisfied.
