The 5 Elements of a Binding Contract

Every legally binding contract — whether on paper, by handshake, or by email — requires five elements. Miss any one and the contract may be voidable or void entirely.

1. Offer

One party makes a clear proposal to do (or not do) something. The offer must be definite enough that acceptance creates a contract. 'I'll consider selling my car for around $5,000' is not an offer; '$5,000 cash, you pick up tomorrow' is.

2. Acceptance

The other party agrees to the offer. Acceptance must mirror the offer (the 'mirror image rule'). Adding terms creates a counter-offer, not acceptance. Acceptance must be communicated — silence isn't acceptance unless prior dealings or the offer specifies.

3. Consideration

Each party gives up something of value. Money for services, goods for money, promise for promise. 'I'll give you my car for free' isn't a contract (no consideration); '$1 for your car' is.

4. Capacity

Both parties must have legal capacity: typically 18+ years old, mentally competent, and not under undue influence or duress. Contracts with minors are voidable by the minor; contracts with intoxicated parties may be void.

5. Legality

The contract's purpose must be legal. Contracts to do illegal things (drug deals, hits, regulatory violations) are unenforceable. Some contracts must be in writing (Statute of Frauds): real estate, agreements lasting >1 year, marriage promises, debt over $500.

What Voids a Contract

Are Email Contracts Binding?

Yes. Under ESIGN Act and UETA, electronic signatures and email exchanges create binding contracts. Even informal '/agreed' emails can form contracts if all 5 elements are present.

FAQ

Is a verbal contract legally binding?

Generally yes, except where the Statute of Frauds requires writing (real estate, marriage, agreements >1 year, debt >$500, sale of goods >$500). But proving terms of verbal contracts is difficult — always get it in writing.

Can a contract be binding without a signature?

Yes. Performance can substitute for signature in many cases. Acceptance by conduct (using a service after seeing terms) creates contracts. But signatures provide cleaner evidence.

What if I signed under pressure?

Duress can void contracts, but only if the pressure was illegal or wrongful (threats of violence, blackmail). Hard negotiating doesn't qualify. Document any genuine duress immediately.
