How is the payment of a commission legally related to agency representation?

The correct choice emphasizes the importance of providing thorough and transparent advice to all parties involved in a real estate transaction. Advising all parties to seek professional counsel when appropriate acknowledges the broader context of agency relationships, which are built not just on financial transactions but also on trust and informed decision-making. This stance ensures that buyers, sellers, and other stakeholders understand their rights and obligations, promoting ethical standards within real estate practices. It highlights the broker's role not only as a representative but also as a facilitator of informed choices, which contributes to a more transparent and trustworthy process.

In the context of the other options, a verbal agreement does not satisfy legal requirements for agency relationships, as many jurisdictions necessitate written agreements to clearly define responsibilities and protect parties involved. Relying solely on written consent from the buyer overlooks the necessity of the seller's acknowledgment and engagement in the commission agreement. Similarly, the notion that a broker must only represent one party is misleading; many brokers can and do represent multiple parties (with proper disclosure and consent), and this flexibility is crucial to their business practice.
