A personal injury attorney is a lawyer that provides legal help to people who claim to have been physically or psychologically injured due to wrongdoing or disregard of another person or entity. Even though personal injury lawyers are licensed and trained to practice any field of law, they generally deal with cases that are considered a branch of tort law including: work injuries (worker’s compensation), auto accidents, medical malpractice, slip and fall accidents, etc. Majority of personal injury victims seek the help of a health care provider. Therefore, it is the attorneys responsibility to find a doctor on lien or letter of protection (LOP) for their client. A doctor on lien/LOP will provide medical help to the client without collecting money upfront. A lien or LOP is used in both personal injury and workers compensation cases.
