What is a contract?

• A. A legally binding agreement for something of value
• B. A casual promise with no consideration
• C. An informal handshake
• D. An unenforceable agreement

Answer: (A)

A contract is a legally binding agreement in which two or more parties promise to do something in exchange for something of value, and the law will enforce that promise. The key ideas here are that there is an offer, an acceptance, and something of value (consideration) exchanged, along with the parties’ intent to be legally bound, capacity to contract, and a lawful purpose. In dentistry practice, a patient agreeing to pay for a specified treatment in return for those services illustrates a contract because there’s mutual assent, a bargained-for exchange, and the promise is enforceable by the courts. Without consideration—that is, a genuine exchange of value—a promise typically isn’t a contract, even if it’s made in good faith. A casual handshake might reflect intent, but it often lacks the enforceable elements unless the other requirements are clearly present. An unenforceable agreement fails the enforceability test for legal reasons, and while it may resemble a contract, it isn’t one in the eyes of the law.
