Why the Distinction Between Material and Immaterial Breach Matters
When a counterparty stops performing, the first question is rarely "can I sue?" It's "can I stop performing too?" That's the real-world weight of the material-breach question. Get it wrong, and the side that walks away can find themselves on the wrong end of the lawsuit.
Nevada's Substantial Performance Standard
Nevada follows the Restatement (Second) of Contracts §241 in evaluating whether a breach is material. The court asks five questions, but the one that matters most in practice is: did the non-breaching party get the substantial benefit they bargained for? A general contractor who finishes a 14,000-square-foot building three days late has substantially performed. A vendor who delivers 60% of an order has not.
The Five-Factor Test, Plainly Stated
No single factor is dispositive. Nevada courts weigh them together — and they weigh them in light of the specific industry. Construction-defect cases lean heavily on factor 4 (cure). Software-license cases lean on factor 1 (delivered benefit).
- How much of the promised benefit was actually delivered
- Whether the non-breaching party can be adequately compensated in damages
- How much the breaching party will lose if performance is forfeited
- Whether the breaching party is likely to cure if given time
- Whether the breaching party's conduct comports with good faith and fair dealing
Practical Steps Before You Treat a Breach as Material
Before you stop performance, three things should happen. First, the breach should be documented in writing — a notice that specifies the contract provision, the breach, and a reasonable cure period. Second, the cure period should be calibrated to the breach (a 30-day cure for a payment dispute, longer for a complex deliverable). Third, you should preserve evidence of your own ongoing performance until the cure window closes.
If the cure window passes without performance, document that fact too — and then make the call about whether to terminate, sue for partial damages, or both.
When the Contract Defines "Material Breach" Itself
Many sophisticated commercial contracts define material breach in the four corners — sometimes by enumerating events, sometimes by setting financial thresholds. Those clauses generally control over the common-law test, but they don't override the implied covenant of good faith and fair dealing. Nevada courts will set aside a contractual definition if applying it would produce a result that effectively negates the bargain.
