The term "negligent party" refers to a person or entity that has been found to have acted carelessly, recklessly or without proper caution in a situation where such behavior is expected. In legal terms, negligence occurs when someone's actions fail to meet the standard of care required in a particular circumstance, resulting in harm to another individual or property damage. A person may be deemed negligent if they breach their duty of care towards others and cause an accident or injury due to their lack of caution. In such cases, the negligent party is held responsible for any damages caused by their actions and must compensate the injured parties accordingly.
