In a purchase contract, what term should be used for a buyer who wishes to remain anonymous?

When a buyer wishes to remain anonymous in a purchase contract, the term "or nominee" is appropriate because it allows the buyer to designate an intermediary or another party without revealing their identity. This term is commonly used in various legal and real estate contexts to signify that the rights of the person entering the contract can be assigned or transferred to another individual or entity. The use of "or nominee" specifically clarifies that the listed buyer is acting on behalf of another party, thus maintaining the original buyer's anonymity while still binding the nominee to the terms of the contract.

This option effectively aligns with the principle of anonymity, as it keeps the identity of the principal buyer out of direct disclosure in the transaction, which can be beneficial for various reasons, such as privacy or strategic business considerations.
