If your case is going to court, and you'll face a judge or jury, you need a lawyer. Self-representation — "pro se," in legal language — works sometimes, but it is never advised. Even attorneys hire other attorneys if they need to appear in court.
Situations Where You Might Need a Lawyer: Being accused of a crime, arrested for DUI/DWI, or other misdemeanors or felonies. Family law issues, such as prenuptials, divorce, child custody, or domestic violence. Business legal matters, including incorporation, purchase, sale, or dissolution.
