Final answer:
An agent can share commission when participating in the sale or rental of a property, such as in scenarios 1 and 2. Real estate agents can split commissions with other licensed agents or brokers but cannot share commission with unlicensed individuals.
Step-by-step explanation:
An agent may share commission with another licensed agent or broker when they participate in a real estate transaction such as the sale or rental of a property. Scenario 1 (When the agent sells a property) and Scenario 2 (When the agent rents a property) are the most common situations in which commission can be shared. Commissions are typically split according to the agreement made between the cooperating real estate agents or brokers. It's important to note that real estate agents cannot share their commission with an unlicensed person. Sharing commission for legal advice or financial services (Scenarios 3 and 4) is not typically related to real estate transactions and may be subject to regulatory and licensure restrictions.
