The South Carolina Bar Association sponsors year-round free legal clinics in locations around the state. You’ll get good information on a range of legal matters, and you’ll also have the opportunity for a short meeting with a lawyer who should be able to answer your questions. Check the association’s website for upcoming clinics scheduled near you.
If you need help right away, contact one of the offices of South Carolina Legal Services. They can help you with most civil cases, if you qualify as a low-income resident of the state. Look for the office in your home county here.
