What Is Breach of Contract?

By FixMyContractLast updated Sep 25, 20262 min read

A breach of contract is when one side doesn't do what the contract says — pays late, delivers less, or doesn't deliver at all. What happens next depends mostly on what the contract itself says about breaches.

Minor and material breaches

In US practice, a minor breach (a short delay) usually leads to a claim for the loss it caused; a material breach (failing the core of the deal) can let the other side end the contract.

Where the contract decides

Notice-and-cure periods, fixed damages, liability caps and dispute clauses all shape what a breach costs. They are worth reading before you sign, not after.

Liquidated damages, limitation of liability, termination for convenience.

An example

A web designer agrees to deliver a site by March 1 for $4,000, paid in two halves. In the US, if the site arrives on March 5 and works, that delay is generally treated as a minor breach: the client can usually claim what the delay actually cost, but cannot end the deal over it — unless the contract makes the date essential (for example, a “time is of the essence” clause). If the site never arrives, the core of the deal has failed, and the termination clause becomes the first place to look.

Four clauses to find before you sign

  • Notice and cure: how many days one side has to fix a problem after written notice.
  • Termination: which breaches let either side end the contract.
  • Liability cap: the most either side can recover.
  • Disputes: court or arbitration, and where.

If the contract is silent on these, the default rules of the state law that governs it fill the gap, and those are harder to predict.

If you think the other side breached

The contract, the dates and the messages are the record. The notice clause usually says how notice has to be sent — often in writing, to a named address. In the US, courts generally hold both sides to a notice step the contract requires, so a claim made without it can be weaker.
