Common Examples

Deed in Lieu Under Pressure
Mortgagor Emmett Egan faced foreclosure on his commercial building. The mortgagee threatened immediate seizure of all rental income unless Egan signed a deed in lieu transferring title. Egan executed the deed only to avoid the threatened loss of cash flow. A court later set aside the transfer because the mortgagee's threat of economic ruin constituted force that negated voluntariness.
Coercive Client Solicitation
Attorney Elijah Edwards telephoned a recent accident victim and demanded an immediate retainer. Edwards warned that refusal would prompt him to contact the client's employer with damaging personal information. The client signed the agreement solely to stop the threats. The solicitation is barred because it employed duress to obtain consent.

Physically Forced Signature
Supplier Eva Espinosa met with a buyer who demanded an exclusive three-year contract. When Espinosa refused and rose to leave, the buyer seized her arm and pressed her hand onto the signature line. Espinosa signed only because physical restraint left her no alternative. The resulting writing is ineffective as a manifestation of assent.
Will Executed Under Threat
Testator Edgar Evers drafted a new will naming his caregiver as sole beneficiary. The caregiver threatened to withhold all medical care unless Evers signed immediately. Evers executed the document only to avoid abandonment. The donative transfer is invalid because it was procured by duress.
Premarital Agreement Coerced
Fiancée Elise Everly was presented with a premarital agreement minutes before the wedding ceremony. Her prospective spouse threatened to cancel the event and publicly humiliate her if she refused to sign. Everly executed the document solely to avert that harm. The agreement is unenforceable because her consent was the product of duress.
Will Contest Alleging Duress
After a testator's death, a disinherited child petitioned to set aside the will. The child introduced evidence that the principal beneficiary had threatened the testator with exposure of private family matters unless the will favored the beneficiary. The contestant bears the burden of proving duress to invalidate the instrument.
Common questions
Frequently Asked
4
What conduct qualifies as duress sufficient to invoke ex vi aut metu?+
Physical compulsion or an improper threat that leaves the victim no reasonable alternative negates effective assent. Courts examine whether the threatened act is itself a crime, tort, or bad-faith use of process.
Does ex vi aut metu render a transaction void or merely voidable?+
Physical duress that prevents any manifestation of assent renders the transaction void. Threats that induce assent render the transaction voidable at the election of the victim.
Who bears the burden of proving duress under ex vi aut metu in a will contest?+
The contestant must establish lack of testamentary intent or capacity, undue influence, fraud, duress, mistake, or revocation.
Can economic pressure alone support a claim of ex vi aut metu?+
Threats of economic ruin or loss of housing may constitute duress when they leave the victim with no reasonable alternative and overcome free will.
