Non-Material Breach

In one sentence

A failure to perform a contract term that is minor and doesn't substantially harm the other party's benefit.

Plain English

When someone breaks a contract in a way that doesn't significantly affect what the other person gets out of the deal, that's a non-material breach. The breaching party hasn't done exactly what they promised, but the failure is relatively small or doesn't go to the heart of the agreement. The other party usually can't cancel the whole contract over a non-material breach, though they may still claim damages for the specific harm caused.

Example

You hire a painter to paint your house blue by next Saturday. The painter finishes on Sunday instead of Saturday, and the color is a perfect match. This late delivery is likely a non-material breach because you still got the main benefit—a properly painted house—just one day late.
