What three things make a contract legally binding?

A legally binding contract requires offer, acceptance, and consideration as its three core foundational elements.

While comprehensive contract law often includes elements like capacity and legality, these three components form the baseline requirements for any enforceable agreement.

Core Elements

• Offer — One party proposes a clear and definite deal or exchange. It outlines what one person will do or provide.
• Acceptance — The second party agrees to the exact terms of the offer without changing them. Any changes made during this step act as a counteroffer instead of a true acceptance.
• Consideration — Both sides must exchange something of value, such as money, services, goods, or a promise to do (or not do) something. This exchange separates a valid contract from a simple gift or free promise.
