the constitution says "no attainder for treason shall work corruption of blood. "

>Corruption of blood is one of the consequences of attainder. The descendants of an attainted person could not inherit either from the attainted person (whose property had been forfeited by the attainder) or through their other relatives from him. For example, if a person is executed for a crime leaving innocent children, the property of the criminal is forfeited to the crown and will not pass to the children. When the criminal's innocent father outlives his son, the property inherited by the father from the criminal cannot be inherited by the criminal's children either: it will be distributed among other family members.
The United States Constitution prohibits corruption of blood as a punishment for treason, (specifically, "no attainder of treason shall work corruption of blood, or forfeiture except during the life of the person attainted") and when Congress passed the first federal crime bill in 1790, it prohibited corruption of blood as a punishment for any federal crime. In England and Wales, corruption of blood was abolished by the Corruption of Blood Act 1814.
