Dixon Juvenile Law Lawyer, Missouri

The money posted by a 'bondsman' for a defendant who cannot afford his bail. The defendant pays a certain portion, usually 10%. If the defendant fails to appear for a court hearing, the judge can issue a warrant for his arrest and threaten to 'forfeit,' or keep, the money if the defendant doesn't appear soon. Usually, the bondsman will look for the defendant and bring him back, forcefully if necessary, in order to avoid losing the bail money.

The defendant's formal answer to criminal charges. Typically defendants enter one of the following pleas: guilty, not guilty or nolo contendere. A plea is usually entered when charges are formally brought (at arraignment).

A minor violation of the law that is punishable only by a fine--for example, a traffic or parking ticket. Not all vehicle-related violations are infractions, however--refusing to identify oneself when involved in an accident is a misdemeanor in some states.

One of the most sacred principles in the American criminal justice system, holding that a defendant is innocent until proven guilty. In other words, the prosecution must prove, beyond a reasonable doubt, each element of the crime charged.

A term that describes vigorous questioning, usually by the police of a suspect in custody. Other than providing his name and address, the suspect is not obligated to answer the questions, and the fact that he has remained silent generally cannot be used by the prosecution to help prove that he is guilty of a crime. If the suspect has asked for a lawyer, the police must cease questioning. If they do not, they cannot use the answers against the suspect at trial.

A method of paying a lawyer for legal representation by which, instead of an hourly or per job fee, the lawyer receives a percentage of the money her client obtains after settling or winning the case. Often contingency fee agreements -- which are most commonly used in personal injury cases -- award the successful lawyer between 20% and 50% of the amount recovered. Lawyers representing defendants charged with crimes may not charge contingency fees. In most states, contingency fee agreements must be in writing.

An affirmative defense to a crime. Self-defense is the use of reasonable force to protect oneself from an aggressor. Self-defense shields a person from criminal liability for the harm inflicted on the aggressor. For example, a robbery victim who takes the robber's weapon and uses it against the robber during a struggle won't be liable for assault and battery since he can show that his action was reasonably necessary to protect himself from imminent harm.

The earliest and most common test for criminal insanity, in which a criminal defendant is judged legally insane only if he could not distinguish right from wrong at the time he committed the crime. For example, a delusional psychotic who believed that his assaultive acts were in response to the will of God would not be criminally responsible for his acts.
