Did you know?

In US law, a felony is typically defined as a crime punishable by a term of imprisonment of not less than one year or by the death penalty. Misdemeanors, in contrast, are often defined as offenses punishable only by fines or by short terms of imprisonment in local jails. Originally, in English law, a felony was a crime for which the perpetrator would suffer forfeiture of all real and personal property as well as whatever sentence was imposed. Under US law, there is no forfeiture of all of the felon’s property, and it is not part of the definition. For certain crimes, however, such as some kinds of racketeering, specific property is subject to forfeiture.

Note: Originally in English law a felony was a crime for which the perpetrator would suffer forfeiture of all real and personal property as well as whatever sentence was imposed. Under U.S. law, there is no forfeiture of all of the felon's property (real or personal) and such forfeiture is not part of the definition of a felony. For certain crimes, however (as for a conviction under the Racketeer Influenced and Corrupt Organizations Act or a narcotics law), specific property, such as that used in or gained by the crime, is subject to forfeiture. Every state has its own statutory definition of a felony. Most are in line with the federal definition of a felony as a crime which carries a sentence of imprisonment for more than one year or the death penalty (where applicable). Other states, like Louisiana, define a felony as a crime which carries a sentence of death or imprisonment at hard labor.
