Counterparts Clauses: Contract for Real Property is a legal document that states that two or more parties can sign different copies of the same contract, and each copy is considered to be a valid and binding agreement. This clause is used in real estate contracts to protect the interests of buyers and sellers, as it allows them to sign separate copies of the same agreement. There are two types of Counterparts Clauses: Contract for Real Property: bilateral and unilateral. A bilateral counterparts' clause allows for the contract to be signed by both parties and be considered valid, while a unilateral counterparts' clause allows only one party to sign the contract, and it will still be considered binding.
