What do we call agreement between two people enforced by law?

The agreement between two people that is enforced by law is called a contract. A contract is a legally binding agreement between two or more parties who have agreed to do something or refrain from doing something in exchange for something of value, known as consideration. For a contract to be valid, there must be an offer made by one party, acceptance of that offer by the other party, and consideration exchanged between the parties. The terms of the contract must be clear and unambiguous, and the parties must have the legal capacity to enter into the agreement. Once a contract is signed, both parties are obligated to fulfill their respective obligations, and if either party breaches the terms of the contract, the other party may seek legal remedies.
