# To be bound by obligations contracted by agent

The principal is required to comply with all the obligations which the agent may have contracted within the scope of his authority.[1] The principal cannot set up the ignorance of the agent as to circumstances whereof the principal himself was, or ought to have been, aware.[2]

Unless the principal expressly or tacitly ratifies an ultra vires act of the agent, the principal is not bound to any obligations where the agent has exceeded his powers.[3]
