An “agent” is a person employed to do any act for, or represent, another in dealing with third persons. The person for whom such an act is done, or who is so represented is called the “principal.”
Any person who is major and sane can employ a person as agent. No requirements as to sanity or majority are necessary in an agent for purposes of binding the principal to third parties but in such cases principal will not be able to enforce his rights against the agent. No consideration is needed between the parties and the authority can either be express or implied. Authority to do an act means implied authority to do every lawful thing supplementary to this act. If the authority is to conduct a business on behalf of the principal, the agent may do all things incidental to this. Special powers lie with an agent in cases of an emergency to protect the interests of the principal.
