Which of the following must be documented in writing to protect the agent legally?

Documentation in writing is particularly crucial when it comes to disclosures regarding hazardous materials. This is because agents are legally obligated to inform buyers of any potential health risks associated with hazardous substances on a property. These disclosures must be documented to provide clear evidence that the buyer was informed, which minimizes the agent's liability in the event of any future issues related to such materials.

While property inspection results and buyer financing details are important, they do not have the same legal requirement for written documentation specifically tied to protecting the agent from liability. Communication with clients is important for maintaining relationships and ensuring clarity, but not all such communications are mandated to be in writing to fulfill legal obligations. Therefore, ensuring that disclosures about hazardous materials are documented serves as a protective measure for the agent in compliance with legal standards.
