Material breach is a contract law term which refers to a failure of performance under the contract which is significant enough to give the aggrieved party the right to sue for breach of contract. When there has been a material breach, the aggrieved party is also relieved of a duty of further performance under the contract. However, a minor divergence from the terms of the contract is not a material breach. A material breach is one that is significant enough to destroy the value of the contract.
A lawsuit for material breach of contract is a civil action and the remedies awarded are designed to place the injured party in the position they would be in if not for the breach. Remedies for contractual breaches are not designed to punish the breaching party.
