A contract is an agreement between parties that the law will enforce — creating obligations that each party is legally bound to perform, and rights that each party is entitled to. It is distinguished from a mere agreement by its legal enforceability: not every agreement is a contract, but a contract is an agreement the law will enforce. Contracts structure employment, business dealings, purchases, leases, and much of everyday life.

Frequently Asked Questions
What is a contract?
A contract is a legally enforceable agreement between parties that creates obligations each party is bound to perform and rights each is entitled to. It is distinguished from a mere agreement by its legal enforceability — the law will enforce it and provide remedies if a party fails to perform. Contracts structure much of work, business, and everyday life, from employment to purchases to leases.
What makes a contract legally enforceable?
An enforceable contract generally requires several elements: an offer by one party and acceptance by the other, consideration (something of value exchanged), and typically capacity and a legal purpose. Some contracts must be in writing to be enforceable. The specific requirements vary by state and jurisdiction, which is why whether a particular agreement is an enforceable contract is a question for a qualified attorney in the relevant jurisdiction.
What is the difference between a contract and an agreement?
An agreement is a mutual understanding between parties, while a contract is an agreement that the law will enforce. Not every agreement is a contract — a contract is distinguished by its legal enforceability, which generally requires elements like consideration. So all contracts are agreements, but not all agreements are contracts; the enforceability is what makes an agreement a contract.
What do contracts create?
Contracts create obligations and rights between the parties. Obligations are what each party must do under the agreement — each party is bound to perform them. Rights are what each party is entitled to — each party is entitled to the other's performance. By creating enforceable obligations and rights, contracts structure dealings between parties, defining what each must do and is entitled to in the arrangement.
Do contracts have to be in writing?
Not all contracts must be in writing — many oral agreements can be enforceable contracts. However, certain types of contracts are generally required to be in writing to be enforceable, under rules that vary by state and jurisdiction. Because whether a particular contract must be written depends on its type and the jurisdiction, this is a question for a qualified attorney. A written contract also provides clearer evidence of the terms.
Should you have a lawyer review a contract?
For significant or complex contracts, having a qualified attorney review it before signing is generally prudent, because they can advise on its enforceability, terms, and implications in your jurisdiction — things general understanding cannot fully assess for a specific contract. Understanding what a contract is helps you recognize when a contract matters and what questions to ask, but a specific contract warrants professional review rather than reliance on general understanding.
