There are 3 classes of duress.
1. Duress to person
2. Duress to property
3. Economic Duress
Contracts under into under duress to property and economic
duress are voidable. Hence the injured party can choose to rescind
the contract or affirm it.
But for contracts entered into under duress to person, the
contract is void at the start. It is treated as though there is no
contract.
