Final answer:
Real estate agents are typically required to have professional liability insurance, also known as errors and omissions insurance, to protect against legal claims related to their professional services.
Step-by-step explanation:
Real estate agents, like many professionals who provide services to the public, are often required to carry a specific type of insurance known as professional liability insurance, sometimes referred to as errors and omissions insurance (E&O insurance). This insurance protects real estate agents in case they are sued for negligence or making an error while providing their professional services. Given the high value of real estate transactions and the potential for legal claims, having this insurance is crucial for protecting both the agent and their clients in the event of unforeseen issues.
