It is necessary to determine whether the party suing (the plaintiff) or the party sued (the defendant) :
(a) is sui juris (of the age majority; and
(b) is in compos mentis (in his right mind); and
(c) is acting personally (ie pursuing his own claim) pr in s representative capacity.
If the plaintiff dies, the executor or the administrator of his estate will be the person to apply for the order to carry on with the proceedings. When one or two or more plaintiffs die, if he cause of action is a joint one, the surviving plaintiff or plaintiffs can continue the action without adding the personal representative of the deceased plaintiff. If the action is not a joint one, the personal representative of the deceased plaintiff may obtain an order to carry on with the proceedings.
In the case of the death of the defendant, if he is the sole defendant and the cause of action is one that survives, the plaintiff may apply for an order to continue the proceedings against the executor or administrator of the deceased defendant. Alternatively, the executor or administrator may apply to be substituted for the defendant. Until and unless such executor or administrator is added or substituted, the action cannot be continued.
