Every day, people enter into contracts without realizing it — clicking "I agree," shaking hands on a deal, or texting a friend to confirm plans. But not every agreement is legally enforceable. Understanding what makes a contract binding can protect you in disputes and help you draft better agreements.
1. Offer
A contract begins with a clear, definite offer. One party proposes specific terms: "I will paint your house for $2,000." Vague statements of intent ("I might be able to help you") are not offers.
An offer can be revoked before it's accepted — but once accepted, it becomes binding.
2. Acceptance
Acceptance must mirror the offer exactly. If you change any terms, that's a counteroffer, not acceptance — and the original offer is no longer on the table.
Acceptance can be verbal, written, or through conduct (starting the work, making a payment). The method of acceptance sometimes matters — if an offer specifies "written acceptance only," a verbal yes won't do.
3. Consideration
Consideration is what each party gives in exchange. It doesn't have to be money — it can be a promise, a service, or even refraining from doing something you have a right to do.
A promise to give someone a gift is not a contract because there's no consideration from the recipient. "I'll give you my car" is a gift. "I'll give you my car if you mow my lawn" is a contract.
4. Mutual Assent
Both parties must genuinely agree to the same terms. Contracts signed under duress, fraud, or misrepresentation lack mutual assent and can be voided.
This is also why contracts must be clear. If the terms are so ambiguous that the parties understood them differently, a court may find there was no meeting of the minds.
5. Legal Capacity and Legality
Both parties must have the legal capacity to contract — meaning they're adults (18+) and of sound mind. Contracts with minors are generally voidable.
The contract's purpose must also be legal. A contract to perform an illegal act is void and unenforceable.
When You Need It in Writing
Verbal contracts can be enforceable — but they're hard to prove. The Statute of Frauds requires written contracts for:
- Real estate transactions
- Agreements that can't be completed within one year
- Sales of goods over $500 (under the UCC)
- Marriage agreements (prenups)
For anything significant, get it in writing.
