In English criminal law, attainder or attinctura is the metaphorical "stain" or "corruption of blood" which arises from being condemned for a serious capital crime (felony or treason). It entails losing not only one's property and hereditary titles, but typically also the right to pass them on to one's heirs. Both men and women condemned of capital crimes could be attainted.
Attainder by confession results from a guilty plea at the bar before judges or before the coroner in sanctuary. Attainder by verdict results from conviction by a jury. Attainder by process results from a legislative act outlawing a fugitive. The latter form is obsolete in England (and prohibited in the United States), and the other forms have been abolished.
