Hiring an auto accident attorney can be very expensive, depending on where you turn. Some lawyers charge very large retainer fees and then bill by the hour. However, there are also attorneys who will charge a contingency fee, meaning that they only get paid if you do, and only a percentage of whatever you receive. It is called a contingency fee because it is contingent on you winning your case. If you do not win, your attorney does not get paid. Depending on the lawyer, you may still be responsible for the expenses related to your case, such as court fees and witness testimony.
