Personal injury lawsuit is a type of litigation filed on behalf of a client who has suffered some form of bodily or personal injury - physical or psychological in nature. This is a class of claims arising out of Tort Law. Tort refers to a civil, as opposed to criminal, wrong which acts as grounds for a lawsuit. A personal injury lawsuit, as a result, may fall into 1 of 3 categories. These are intentional, negligent and strict liability. Intentional tort refers to the defendant's deliberate act of such things pushing, hitting, striking and other actions resulting in the personal injury. Negligent lawsuits arise when there is an instance when the failure to obey or heed specific laws or rules produces the personal injury. Strict liability refers to instances where an ordinarily lawful activity exposes others to unnecessary risks. In all instances, you may require a civil litigation attorney. You may specifically desire a specialist in personal injury lawsuits.
