Definition: giấy ủy nhiệm.
A more thorough explanation: A warranty of authority is a legal term that refers to a representation made by an individual or entity that they have the legal authority to act on behalf of another party in a particular transaction or matter. This warranty implies that the person making the representation has the necessary legal capacity and authorization to enter into the transaction or make decisions on behalf of the other party. If it is later discovered that the individual did not have the authority they claimed to have, they may be held liable for any resulting damages or losses.
Example: The warranty of authority provided by the agent assured the third party that the agent had the legal right to act on behalf of the principal in the transaction.
