##### Learning Objectives
1. Recognize that if a person makes an agreement under duress (being forced to enter a contract against his or her will), the agreement is void.
2. Understand what undue influence is and what the typical circumstances are when it arises to make a contract voidable.

## Duress

When a person is forced to do something against his or her will, that person is said to have been the victim of duress—compulsion. There are two types of duress: physical duress and duress by improper threat. A contract induced by physical violence is void.

## Physical Duress

If a person is forced into entering a contract on threat of physical bodily harm, he or she is the victim of physical duress. It is defined by the Restatement (Second) of Contracts in Section 174: “If conduct that appears to be a manifestation of assent by a party who does not intend to engage in that conduct is physically compelled by duress, the conduct is not effective as a manifestation of assent.”

Comment (a) to Section 174 provides in part, “This Section involves an application of that principle to those relatively rare situations in which actual physical force has been used to compel a party to appear to assent to a contract.…The essence of this type of duress is that a party is compelled by physical force to do an act that he has no intention of doing. He is, it is sometimes said, ‘a mere mechanical instrument.’ The result is that there is no contract at all, or a ‘void contract’ as distinguished from a voidable one” (emphasis added).

The Restatement is undoubtedly correct that there are “relatively rare situations in which actual physical force” is used to compel assent to a contract. Extortion is a crime.

## Duress by Threat

The second kind of duress is duress by threat; it is more common than physical duress. Here the perpetrator threatens the victim, who feels there is no reasonable alternative but to assent to the contract. It renders the contract voidable. This rule contains a number of elements.

First, the threat must be improper. Second, there must be no reasonable alternative. If, for example, a supplier threatens to hold up shipment of necessary goods unless the buyer agrees to pay more than the contract price, this would not be duress if the buyer could purchase identical supplies from someone else. Third, the test for inducement is subjective. It does not matter that the person threatened is unusually timid or that a reasonable person would not have felt threatened. The question is whether the threat in fact induced assent by the victim. Such facts as the victim’s belief that the threatener had the ability to carry out the threat and the length of time between the threat and assent are relevant in determining whether the threat did prompt the assent.

There are many types of improper threats that might induce a party to enter into a contract: threats to commit a crime or a tort (e.g., bodily harm or taking of property), to instigate criminal prosecution, to instigate civil proceedings when a threat is made in bad faith, to breach a “duty of good faith and fair dealing under a contract with the recipient,” or to disclose embarrassing details about a person’s private life.

Jack buys a car from a local used-car salesman, Mr. Olson, and the next day realizes he bought a lemon. He threatens to break windows in Olson’s showroom if Olson does not buy the car back for \$2,150, the purchase price. Mr. Olson agrees. The agreement is voidable, even though the underlying deal is fair, if Olson feels he has no reasonable alternative and is frightened into agreeing. Suppose Jack knows that Olson has been tampering with his cars’ odometers, a federal offense, and threatens to have Olson prosecuted if he will not repurchase the car. Even though Olson may be guilty, this threat makes the repurchase contract voidable, because it is a misuse for personal ends of a power (to go to the police) given each of us for other purposes. If these threats failed, suppose Jack then tells Olson, “I’m going to haul you into court and sue your pants off.” If Jack means he will sue for his purchase price, this is not an improper threat, because everyone has the right to use the courts to gain what they think is rightfully theirs. But if Jack meant that he would fabricate damages done him by a (falsely) claimed odometer manipulation, that would be an improper threat. Although Olson could defend against the suit, his reputation would suffer in the meantime from his being accused of odometer tampering.

A threat to breach a contract that induces the victim to sign a new contract could be improper. Suppose that as part of the original purchase price, Olson agrees to make all necessary repairs and replace all failed parts for the first ninety days. At the end of one month, the transmission dies, and Jack demands a replacement. Olson refuses to repair the car unless Jack signs a contract agreeing to buy his next car from Olson. Whether this threat is improper depends on whether Jack has a reasonable alternative; if a replacement transmission is readily available and Jack has the funds to pay for it, he might have an alternative in suing Olson in small claims court for the cost. But if Jack needs the car immediately and he is impecunious, then the threat would be improper and the contract voidable. A threat to breach a contract is not necessarily improper, however. It depends on whether the new contract is fair and equitable because of unanticipated circumstances. If, for example, Olson discovers that he must purchase a replacement transmission at three times the anticipated cost, his threat to hold up work unless Jack agrees to pay for it might be reasonable.
