Mistake in Law: Types, Definitions, and Contract Implications

Definition & Meaning

A mistake in legal terms refers to an error in understanding facts, the meaning of words, or the law itself. This misunderstanding can lead one or both parties to enter into a contract without fully grasping their responsibilities or potential outcomes. When a mistake occurs, it may provide grounds for rescission, which is the cancellation of the contract. However, a unilateral mistake, where only one party holds an incorrect belief, typically does not justify rescission, as the principle of "ignorance of the law is no excuse" applies. Mistakes can be classified into two main types: unilateral mistakes and mutual mistakes, with mutual mistakes being more likely to render a contract voidable.

Real-world examples

Here are a couple of examples of abatement:

(hypothetical example) A buyer purchases a piece of land believing it to be zoned for commercial use. After the sale, they discover it is actually zoned for residential use only. This misunderstanding may allow the buyer to seek rescission of the contract based on a mutual mistake.

(hypothetical example) A seller mistakenly lists a car as having a clean title, but it has a salvage title. If the buyer was unaware of this fact, they may have grounds to cancel the contract due to a unilateral mistake.
