Parties are legally allowed to represent themselves, but keep in mind that the law is highly nuanced. A lawyer will help you organize your case, suggest the best tactics, prepare you for what to expect if and when you have to go to court, and be another voice advocating on your behalf. The chances are that a lawyer has seen a case like yours many times before and will know the right approach to take in your situation. It is important that your lawyer is well versed in the type of case you are facing, which is why even lawyers themselves will retain another lawyer when they are facing a personal legal battle.
