Question 1

What qualifies as duress in contract law?

Accepted Answer

There are two main types. Physical duress: threats of violence or harm. Economic duress: illegitimate financial pressure that leaves you no reasonable alternative but to agree. 'Sign this or I'll break your legs' is obvious. 'Sign this unfair amendment or I'll withhold the $200,000 payment I already owe you' — that's economic duress.

Question 2

How do I prove duress?

Accepted Answer

Show three things: (1) the other party made an illegitimate threat, (2) you had no reasonable alternative but to agree, and (3) the threat actually caused you to sign. Document everything — save threatening emails, record conversations (where legally allowed), and note dates and witnesses. The harder part is usually proving you had 'no reasonable alternative.'

Question 3

Can I void a contract I signed under duress?

Accepted Answer

Yes. A contract signed under duress is voidable — you can choose to cancel it and potentially recover any money or property you gave up. But you must act promptly after the duress ends. If you continue performing under the contract for months after the pressure stopped, a court might find you ratified it.

Question 4

Is a hard negotiation tactic the same as duress?

Accepted Answer

No. Tough negotiations are legal. 'Take it or leave it' isn't duress — it's just hardball. Duress requires an illegitimate threat (not just a strong position) and no reasonable alternative (not just an unpleasant one). 'I'll sell to your competitor if you don't agree' is tough negotiation. 'I'll breach our existing contract to destroy your business if you don't agree' — that crosses into duress.

Question 5

What happens if I can prove economic duress?

Accepted Answer

The contract is voidable at your option. You can rescind it and seek damages for any losses caused by the coerced agreement. Courts may also award restitution — putting you back in the position you were in before the contract was signed. The party who applied the duress can also face separate claims for bad faith or tortious interference.

Question 6

What's the difference between duress and undue influence?

Accepted Answer

Duress involves threats and coercion from the outside. Undue influence involves manipulation by someone in a position of trust — a lawyer, doctor, caretaker, or family member. A contractor threatening to walk off a job mid-project unless you pay double is duress. An elderly person's caretaker convincing them to sign over their property is undue influence.
