Final answer:
Agency agreements usually need to be in writing for commissions to be collected, but there are legal exceptions where an oral agreement may suffice.
Step-by-step explanation:
The question relates to agency agreements in a business context, typically found in the real estate or brokerage industries where an agent acts on behalf of a principal to perform certain services. As per general business law, these agreements often need to be in writing, or confirmed in writing, for the agent to collect a commission except in certain scenarios. However, there are exceptions to this rule, such as oral agreements that are legally recognized under certain circumstances or due to specific local regulations. For instance, if a person acted as an agent and performed services with the principal’s acknowledgment, a written agreement may not be necessary if the arrangement is recognized legally.
