Agency of Shipmasters and Business Managers

There were two special instances of a purely commercial character in which persons sui juris as well as slaves and persons under power might act practically as agents.

The master or captain of a ship (magister navis) might bind the owner (exercitor) by contracts relating to the ship and its business. And a person (institor) put in charge of a shop or other business could bind his principal by contracts within the scope of the business entrusted to him. These were the only cases in which persons not slaves nor under power could act as agents, and they were agents only in a partial sense. Their contracts bound their principals, and third persons with whom they contracted could sue the principals directly on the contracts. But except in a few cases the principal could not sue the third person directly. His only remedy was against the shipmaster directly or against the manager to compel him to transfer his right of ac- tion. Moreover, unlike a true agent, the master of the ship or manager of the business was personally liable on his contracts.

The remedy granted by the prsetor against the principal was the actio exerciforia in the case of the shipmaster, and the actio institutoria in the case of the manager. These two actions together with the quasi-agency or slaves and persons under power probably served fairly well the needs of the Romans.
