Which of the following is NOT a requirement for real estate contracts?

In real estate contracts, certain elements are essential for the agreement to be considered valid and enforceable. One of these key requirements is that it must involve the signatures of both parties—buyer and seller—indicating their mutual consent to enter into the contract.

The inclusion of a detailed description of the real estate being sold is crucial as it clearly identifies the property involved in the transaction. Additionally, consideration—something of value exchanged between the parties, typically money—provides the basis for the contract and makes it binding.

The statement that only a buyer's signature is required reflects a misunderstanding of contract formation, as both parties must express their agreement through their signatures to validate the contract. Therefore, the correct choice demonstrates an incomplete understanding of the legal requirements for real estate contracts.
