What term describes the facilitation of a financial transaction by a third party between two parties?

The term that best describes the facilitation of a financial transaction by a third party between two parties is intermediation. In the context of real estate and financial transactions, intermediation involves a broker, agent, or other third-party facilitator who assists in connecting buyers and sellers, ensuring that the transaction proceeds smoothly. This includes activities such as negotiating terms, handling documentation, and ensuring compliance with legal requirements.

While negotiation refers to the process of discussing and reaching an agreement on the terms of a deal, it does not encapsulate the broader role of a third party in facilitating a transaction. Representation typically involves an agent representing the interests of a client, which is more focused on loyalty and advocacy rather than facilitation. Conveyance refers to the legal process of transferring property from one party to another, but does not involve the intermediary role in a transaction. Thus, intermediation accurately captures the essence of a third party's involvement in financial transactions.
