We all know someone who sustained an injury and their medical bills went through the roof. Lost wages were among many financial difficulties suffered by this person and we never want to be in their shoes. But does everyone know when the justification to pursue a lawsuit is required. Certainly not every injury warrants this type of legal proceeding but when damages are sought, a personal injury lawyer is there to help. There are three types of cases that will warrant a lawyer and they are intentional wrong, negligence and strict liability. Intentional wrong is difficult to prove. The act of intentionally hurting someone is a serious act and the burden of proof is on the plaintiff. A strong personal injury case would be one of malicious injury or sabotage. Negligence is the most typical personal injury lawsuit. Not stopping at a stop light and causing a collision is the most common type as a failure to follow rules that are there to protect society is considered negligence. Strict liability involves products and services connected to a business or organization. Faulty stairways of unlit passageways in an apartment complex are subject to strict liability lawsuit is renters are injured.
