Which concept ensures that the obligations of a contract are legally enforceable?

The concept that ensures the obligations of a contract are legally enforceable is the presence of consideration. Consideration refers to something of value that is exchanged between the parties involved in the contract. It is a fundamental principle in contract law that requires each party to provide something of value, whether it be a service, money, or a promise to do (or not do) something. This exchange solidifies the commitment of each party and creates a binding agreement, as the law recognizes that contracts without consideration are typically unenforceable.

In the absence of consideration, a contract may lack the necessary legal foundation to be upheld in a court. Thus, it plays a crucial role in distinguishing enforceable contracts from mere promises or informal agreements that do not carry legal weight.
