A breach of contract happens when a party fails to perform a contractual duty without a recognized legal excuse. In plain language, one side did not do what the contract required.
Why It Matters
This term matters because contract disputes usually move from formation questions to performance questions. Once a contract exists, the next issue is often whether someone failed to deliver goods, pay money, meet deadlines, maintain confidentiality, or satisfy another promised obligation.
Breach also matters because not every failure has the same consequence. Some breaches are minor and may allow recovery of limited damages, while a more serious failure may justify termination or more extensive relief.
Where It Appears
Breach of contract appears in demand letters, complaints, settlement negotiations, arbitration proceedings, and court opinions. It is central when a plaintiff claims the defendant failed to perform and seeks damages or another remedy.
Practical Example
A vendor agrees to deliver software integration services by a fixed launch date but never supplies the final work product. The customer may claim the vendor breached the contract by failing to perform as promised.
