Listing contracts must be completed:

Listing contracts must be completed in duplicate because this practice ensures that both the seller and the brokerage have a signed copy of the agreement for their records. This is important for clarity and legal reasons, as each party needs to clearly understand the terms and conditions agreed upon. Having duplicate copies helps to reduce potential disputes regarding the details of the contract.

Completing contracts in triplicate or quadruplicate is generally not necessary for standard real estate dealings, as it would only complicate matters and is typically reserved for specific situations or additional parties involved. Oral agreements, while sometimes valid in real estate, lack the legal enforceability and clarity that a written document provides. Therefore, the requirement for listing contracts to be in duplicate aligns with best practices in the industry for documentation and accountability.
