Would it be cheaper to just represent myself in court?

It might be less expensive to assume all of the legal responsibilities of representing yourself, but it could be extremely risky. Without a detailed knowledge of the law and legal system, a person defending him or herself could end up making a significant mistake, resulting in greater penalties. Additionally, a large part of hiring a defense attorney is the representation they can provide you, making your presence at many legal proceedings unnecessary. Because of these reasons, it is generally not advisable for a person to represent themselves; it could actually end up costing them much, much more.
