When someone is assaulted, whether by a stranger, friend, family member, romantic partner or business associate, there is a feeling of violation and also possible medical expenses that result. Whether or not criminal assault charges are being pressed against the person who hit or otherwise physically struck out against you, you can still sue the perpetrator in a civil court of law. Depending on how serious the case is, you can do it yourself in small claims court or secure the services of a personal injury attorney to sue the assailant in a higher civil court.
Gather any witnesses and records. You will need to do this even if you get an attorney. You know better than anyone else what persons saw the assault and who treated you for medical or other needs after the assault. Your lawyer can best help you if you provide him as much information as possible. If you have a police report or restraining order against the assailant, you have a much stronger case. Be sure to obtain any proof of lost wages or medical bills.
