What must a broker do if a salesperson prepares a contract?

The correct answer highlights the broker's responsibility regarding contracts prepared by salespersons. In Minnesota real estate regulations, it is established that a broker must ensure that any contract prepared by a salesperson falls within the legal parameters and accurately represents the intentions of the parties involved. This means that the broker needs to be aware of the contents of the contract and is ultimately responsible for its accuracy, even if the salesperson prepared it.

By holding the broker liable for the accuracy of the contract, it emphasizes the importance of having oversight and maintaining high ethical standards in real estate transactions. This responsibility not only protects the clients but also upholds the integrity of the brokerage firm.

The other options reflect duties that are less aligned with the broker's primary obligations or may not be necessary in every situation. For example, while reviewing and signing the contract could be beneficial for quality assurance, it is not a mandatory requirement under all circumstances. Similarly, filing the contract with regulatory bodies is not a general obligation that brokers must fulfill for every contract, as this requirement may depend on specific legal contexts or types of agreements.
