Final answer:
Express authority is conveyed onto an agent in business through explicit instructions or agreements between the principal and the agent. It can be either oral or written. It's important to note that express authority is limited to the specific instructions given or implied by the principal.
Step-by-step explanation:
Express authority is conveyed onto an agent in business through explicit instructions or agreements between the principal and the agent. It can be either oral or written. For example, a company may give an employee the authority to negotiate contracts on its behalf by providing written instructions or issuing a power of attorney document.
Express authority can also be conveyed through the actions of the principal. If a principal consistently allows an agent to act on their behalf in certain matters, it implies that the agent has authority in those specific areas.
It's important to note that express authority is limited to the specific instructions given or implied by the principal. Anything beyond the scope of the express authority would require separate authorization or fall under implied authority or apparent authority.
