A roofing contractor finishes two weeks late with the wrong shingles. The homeowner refuses to pay anything. Who breached, how badly, and what each side recovers depends entirely on whether the breach is material or partial.
Every breach question starts the same way: classify. Remedies flow from the classification.
A material breach is a failure so significant that it substantially defeats the purpose of the contract. The non-breaching party may suspend performance, cancel, and sue for total damages. Material breach is the only classification that lets you walk away.
A partial (or minor) breach is defective performance that does not defeat the purpose. The non-breaching party must still perform but can sue for the loss caused by the defect.
Courts weigh how much benefit was still received, whether money damages are adequate, whether forfeiture would result, whether the breach was willful, and how likely cure is.
KEY: Classification controls whether you can stop performing. Pick wrong, and the "non-breaching" party becomes the breaching party.
Common mistakes
- Treating every breach as material. Defective performance is usually partial. A non-breaching party who walks away from a partial breach has themselves committed a material breach. Look for "substantially," "still functional," "minor deviation."
- Awarding consequential damages without checking foreseeability. Lost profits only count if the breaching party knew of the special circumstances at signing. The trap answer is "all foreseeable losses are recoverable."
- Calling every pre-set damages clause "liquidated damages." Enforceable only if actual damages were hard to estimate AND the amount is a reasonable forecast. A grossly disproportionate amount is a penalty, regardless of label.
Bottom line
- Material breach excuses performance and unlocks total damages plus cancellation. Partial breach does not; keep performing and sue for the loss.
- Substantial performance lets a good-faith breaching party recover contract price minus cost to cure or diminution in value; willful breach loses this protection.
- Anticipatory repudiation is an unequivocal refusal before performance is due; treat it as immediate breach. Hedged statements only trigger a right to demand assurance under UCC 2-609.
- Compensatory damages equal expectation interest; consequential are foreseeable downstream losses (Hadley v. Baxendale, foreseeable at contracting); incidental are costs of dealing with the breach.
Exam shortcut
Classify the breach FIRST. Material unlocks cancellation plus damages; partial keeps you performing with a damages claim for the defect. Then run the remedies checklist: compensatory (always), incidental (almost always), consequential (only if foreseeable at signing), liquidated (only if reasonable, not a penalty), specific performance (only for unique goods or land, never services), rescission and restitution (for material breach, fraud, mistake). Then check mitigation.
