The party to the contract who enters into it by reason of duress may take advantage of such duress to avoid liability under the contract,1 and, after his death, his heirs may have their ancestor's conveyance set aside for duress.2 As a general rule this privilege is personal to him and his legal representatives. The adversary party who is guilty of duress can not avoid the contract by reason thereof.3 A third person can not set up such duress.4 A creditor of the party subjected to duress, who has attached property sold by the latter under duress, can not avoid the contract for such duress.5
