A bilateral mistake occurs when both parties to a contract misunderstand a fundamental aspect of the agreement, leading to a situation where neither party has a true understanding of what they are agreeing to. This type of mistake can render a contract voidable.
### Example of a Bilateral Mistake:
Imagine two parties, Alice and Bob, who enter into a contract for the sale of a painting. Both believe the painting is an original work by a famous artist, valued at $100,000. However, unbeknownst to both parties, the painting is actually a reproduction worth only $10,000.
In this case:
- **Mutual Misunderstanding**: Both Alice and Bob mistakenly believe that the painting is an original. This is a fundamental aspect of their agreement.
- **Impact on the Contract**: Because both parties were under the same misconception about the value and nature of the painting, they might choose to void the contract. Alice may argue that she would not have agreed to sell the painting for $100,000 if she had known it was a reproduction, and Bob would not have paid that amount for something he believed was an original.
### Legal Implications:
In such a situation, either party may seek to rescind the contract based on the bilateral mistake, as both parties entered the agreement under a shared misunderstanding that affects the very essence of their contract.
