Consent removes error; acquiescence in error takes away the right of objecting to it.

Explanation

A party who consents to or acquiesces in an error, knowing of it and having the opportunity to object, waives his right to later challenge it — consent cures defects, but only where the acquiescence itself is free and informed.

Where this applies

• There was an error in the contract but both parties went ahead and performed anyway.
• I knew the paperwork had a mistake but I accepted it without objection.
