If you’ve been harmed by another driver, from a defective or dangerous product, or by the actions of a person or business there is no law or rule that you must hire a personal injury lawyer. You always have the right to represent yourself, but that doesn't mean it's a wise choice. Since personal injury attorneys often work on contingency, it is likely in your best interest to consult with one to determine whether or not you have a case. Better to be safe than sorry. Because you must file a lawsuit within a certain period of time and evidence is best preserved closer to the date of the accident, be sure to consult with a local attorney as soon as possible.
