The Contract Exists. But Is the Consent Valid?
A signed agreement can still be challenged when consent was based on a serious mistake, false information, threats, or improper influence.
Mutual mistake
Both parties are mistaken about a material basic assumption, which can affect enforceability when applicable requirements are met.
Unilateral mistake
Only one party is mistaken, so relief is generally more limited unless additional facts justify it.
Misrepresentation
A false statement can undermine consent, and fraudulent misrepresentation involves intentional or reckless deception under applicable law.
Duress and undue influence
Duress involves improper threats. Undue influence involves unfair use of a relationship of trust or dominance.
The takeaway
Mistake concerns assumptions. Misrepresentation concerns false information. Duress concerns threats. Undue influence concerns improper relational pressure.
