Decoding Legal Jargon: A Layman’s Guide

Legal Term for Insanity: Not Guilty by Reason of Insanity (NGRI)

The legal term for insanity is “Not Guilty by Reason of Insanity” or NGRI. This is a defense used in criminal cases where the defendant claims that they were so mentally disturbed at the time of the crime that they couldn’t understand the nature of their actions. This defense is not easy to prove and requires substantial medical evidence.

Legal Term for Slander: Defamation

Slander is a form of defamation, which is the act of making false statements about someone to damage their reputation. While defamation can be either written (libel) or spoken (slander), the term “slander” specifically refers to spoken or oral defamatory statements.

Legal Term for Act of God: Force Majeure

The legal term for an “Act of God” is “Force Majeure.” This refers to unforeseeable circumstances that prevent someone from fulfilling a contract. Natural disasters like hurricanes, earthquakes, and floods often fall under this category. Force Majeure clauses are commonly included in contracts to protect parties from legal liability in such cases.

In legal proceedings, “discovery” refers to the pre-trial phase where each party can obtain evidence from the opposing side. This process is formally known as “disclosure.” It includes interrogatories, depositions, and requests for documents, among other things.

The legal term for lying, especially under oath, is “perjury.” This is a criminal offense and is punishable by law. Perjury can significantly impact court proceedings and is taken very seriously.
