Ramon G Songco Jenny Jean B Domino The service of a summons is indispensable in judicial proceedings. It both notifies the defendant that a suit has been brought against it and enables the court to acquire jurisdiction over the defendant in person, thus making any court order or ruling in such a case binding upon that defendant. This acquires particular relevance in cases of in personam actions, which are based on the defendant's personal liability. In contrast, in an action in rem, the judgment pertains to the thing that is the subject of the action and the court need not acquire jurisdiction over the defendant in person, only over the thing itself.
