Which of the following statements about an exclusive listing contract is not true under Nevada law?

An exclusive listing contract in Nevada allows the seller to grant a specific real estate agent or broker the exclusive right to market and sell their property. Under Nevada law, it is completely legal to include automatic extension clauses in these contracts, which means that option D, stating it is illegal to have automatic extension clauses, is not true.

When an exclusive listing includes an automatic extension clause, it means that the period of exclusivity can automatically renew after a certain timeframe unless one of the parties formally decides to terminate the contract. This feature can be beneficial for both agents and sellers, as it ensures continuity in the marketing of the property.

On the other hand, the other choices reflect valid aspects of exclusive listing agreements. A seller can indeed terminate an exclusive listing at any time, provided they follow the appropriate legal process. The requirement for the contract to be in writing is essential for enforceability and to protect the interests of both parties involved. Hence, option D is the only statement that does not align with Nevada law regarding exclusive listing contracts.
