A crime is a wrongdoing classified by the state or Congress as a felony or misdemeanor.
Felony. A felony is a serious crime punishable by at least one year in prison. Some family law felonies include kidnapping and custodial interference (in some states).
People convicted of felonies lose certain rights, such as the right to vote or hold public office. During the term of sentence, the convicted person may also be prohibited from making contracts, marrying, suing or keeping certain professional licenses. Upon release from prison, the convict may also be required to register with the police.
Misdemeanor. A misdemeanor is a crime for which the punishment is usually a fine and/or up to one year in a county jail. Often a crime which is a misdemeanor for the first offense becomes a felony for repeated offenses. All crimes that are not felonies are misdemeanors.
