Duress per minas is a Latin term meaning, threat of loss of life. Duress per minas also means causing fear with threat of loss of limb or other harm to a person. In civil cases the rule as to duress per minas has a broader application at the present day than it formerly had.
The nature of the common law duress per minas is to enable the person threatened with this pernicious control to avoid a bond or note obtained without consideration by means of such threats. However, Mere threats of injury to property, without power over it to enable the party to execute the threats, are not duress per minas.[Miller v. Miller, 68 Pa. 486 (Pa. 1871)].
