Which term describes the relationship established by a written contract?

The term that describes the relationship established by a written contract is contractual privity. This concept refers to the direct relationship and legal connection between the parties involved in a contract. Essentially, when two or more parties sign a written contract, they enter into an agreement that creates specific rights and responsibilities that are enforceable by law. Contractual privity ensures that the parties are bound by the terms laid out in the contract and can rely on the legal enforceability of those terms.

Other related terms in the options, such as legal representation, refer more to the roles of attorneys or individuals acting on behalf of a party, rather than the relationship between the parties themselves. Contractual obligations involve the duties that each party must fulfill according to the contract, but this does not capture the essence of the relationship established. Mutual benefit pertains to the idea that both parties gain from the contract, but it does not define the legal relationship itself. Thus, while all these terms are related to contracts, contractual privity specifically addresses the binding nature of the agreement between the parties involved.
