Legal Terms Glossary
The Legal Terms Glossary defines over 100 of the most common legal terms in easy-to-understand language. Terms are listed in alphabetical order and can be better accessed by choosing a letter here:
acquittal - Judgment that a criminal defendant has not been proven guilty beyond a reasonable doubt.
affidavit - A written statement of facts confirmed by the oath of the party making it. Affidavits must be notarized or administered by an officer of the court with such authority.
affirmed - Judgment by appellate courts where the decree or order is declared valid and will stand as decided in the lower court.
Alford plea - A defendant’s plea that allows him to assert his innocence but allows the court to sentence the defendant without conducting a trial. Essentially, the defendant is admitting that the evidence is sufficient to show guilt. Such a plea is often made for purposes of negotiating a deal with the prosecutor for lesser charges or a sentence.
allegation - Something that someone says happened.
answer - The formal written statement by a defendant responding to a civil complaint and setting forth the grounds for defense.
appeal - A request made after a trial, asking another court (usually the court of appeals) to decide whether the trial was conducted properly. To make such a request is "to appeal" or "to take an appeal." Both the plaintiff and the defendant can appeal, and the party doing so is called the appellant. Appeals can be made for a variety of reasons including improper procedure and asking the court to change its interpretation of the law.
appellate - About appeals; an appellate court has the power to review the judgment of another lower court or tribunal.
arraignment - A proceeding in which an individual who is accused of committing a crime is brought into court, told of the charges, and asked to plead guilty or not guilty.
arrest warrant - A written order directing the arrest of a party. Arrest warrants are issued by a judge after a showing of probable cause.
bail - Security given for the release of a criminal defendant or witness from legal custody (usually in the form of money) to secure his/her appearance on the day and time appointed.
bankruptcy - Refers to statutes and judicial proceedings involving persons or businesses that cannot pay their debts and seek the assistance of the court in getting a fresh start. Under the protection of the bankruptcy court, debtors may discharge their debts, perhaps by paying a portion of each debt. Bankruptcy judges preside over these proceedings.
bench trial - Trial without a jury in which a judge decides the facts. In a jury trial, the jury decides the facts. Defendants will occasionally waive the right to a jury trial and choose to have a bench trial.
beyond a reasonable doubt - Standard required to convict a criminal defendant of a crime. The prosecution must prove the guilt so that there is no reasonable doubt to the jury that the defendant is guilty.
binding precedent - A prior decision by a court that must be followed without a compelling reason or significantly different facts or issues. Courts are often bound by the decisions of appellate courts with authority to review their decisions. For example, district courts are bound by the decisions of the court of appeals that can review their cases, and all courts – both state and federal – are bound by the decisions of the Supreme Court of the United States.
brief - A written statement submitted by the lawyer for each side in a case that explains to the judge(s) why they should decide the case (or a particular part of a case) in favor of that lawyer's client.
capital offense - A crime punishable by death. In the federal system, it applies to crimes such as first degree murder, genocide, and treason.

chambers - A judge's office.
charge - The law that the police believe the defendant has broken.
charge to the jury - The judge's instructions to the jury concerning the law that applies to the facts of the case on trial.

counsel - Legal advice; a term used to refer to lawyers in a case.
counterclaim - A claim that a defendant makes against a plaintiff. Counterclaims can often be brought within the same proceedings as the plaintiff’s claims.

discovery - Lawyers' examination, before trial, of facts and documents in possession of the opponents to help the lawyers prepare for trial.
docket - A log containing brief entries of court proceedings.
en banc - "In the bench" or "full bench." Refers to court sessions with the entire membership of a court participating, rather than the usual quorum. U.S. courts of appeals usually sit in panels of three judges, but may expand to a larger number in certain cases they deem important enough to be decided by the entire court. They are then said to be sitting en banc.
evidence - Information presented in testimony or in documents that is used to persuade the fact finder (judge or jury) to decide the case for one side or the other.
exculpatory evidence - Evidence which tends to show the defendant’s innocence.
exhibit - Physical evidence or documents that are presented in a court proceeding. Common exhibits include contracts, weapons, and photographs.

Grand jury proceedings are closed to the public, and the person suspected of having committed the crime is not entitled to be present or have an attorney present. States are not required to use grand juries, but the federal government must do so under the Constitution.
habeas corpus - A writ that is often used to bring a prisoner before the court to determine the legality of his imprisonment. A prisoner wanting to argue that there is not sufficient cause to be imprisoned would file a writ of habeas corpus. It may also be used to bring a person in custody before the court to give testimony, or to be prosecuted.

jurisdiction - (1) The legal authority of a court to hear and decide a case. Concurrent jurisdiction exists when two courts have simultaneous responsibility for the same case. Some issues can be heard in both state and federal courts. The plaintiff initially decides where to bring the suit, but in some cases, the defendant can seek to change the court. (2) The geographic area over which the court has authority to decide cases. A federal court in one state, for example, can usually only decide a case that arose from actions in that state.

nolo contendere - No contest. Has the same effect as a plea of guilty as far as the criminal sentence is concerned, but the plea may not be considered an admission of guilt for any other purpose. Sometimes, a guilty plea could later be used to show fault in a lawsuit, but the plea of nolo contendere forces the plaintiff in the lawsuit to prove that the defendant committed the crime.
oath - A promise to tell the truth.
objection - A protest by an attorney, challenging a statement or question made at trial. Common objections include an attorney “leading the witness” or a witness making a statement that is hearsay. Once an objection is made, the judge must decide whether to allow the question or statement.

It may include lesser charges, a dismissal of charges, or the prosecutor’s recommendation to the judge of a more lenient sentence.
pleadings - Written statements of the parties in a civil case of their positions. In federal courts, the principal pleadings are the complaint and the answer.
precedent - A court decision in an earlier case with facts and law similar to a dispute currently before a court. Precedent will ordinarily govern the decision of a later similar case, unless a party can show that it was wrongly decided or that it differed in some significant way.

reporter - Makes a record of court proceedings, prepares a transcript, and publishes the court's opinions or decisions.
reverse - When an appellate court sets aside the decision of a lower court because of an error. A reversal is often followed by a remand. For example, if the defendant argued on appeal that certain evidence should not have been used at trial, and the appeals court agrees, the case will be remanded in order for the trial court to reconsider the case without that evidence.
search warrant - Orders that a specific location be searched for items, which if found, can be used in court as evidence. Search warrants require probable cause in order to be issued.
