Answer:
ratification
Step-by-step explanation:
The principal agent relationship can be very complex, since the principal is bound to the agent's actions, and things can get complicated if someone uses apparent authority to act on behalf of a principal.
The only way a principal is bound to the acts of an agent is if the agent has actual, implied or apparent authority. Actual and implied authority are given by the principal, so the principal is responsible for the agent's acts. If the agent wasn't authorized, then the only way a transaction can be binding is that if the agent had apparent authority.
When an unauthorized agent commits or agrees to a transaction on behalf of a principal and the principal decides to accept the transaction's terms, the principal is ratifying (or accepting) those actions.
