Most good medical malpractice attorneys will agree to prosecute malpractice claims on a contingency fee arrangement. This means that the attorney will not charge an hourly rate for his services, but instead will be paid a percentage of the recovery in the event of a settlement or judgment. In many cases, costs are advanced on behalf of the client and are payable, interest free, at the conclusion of the case. Costs include such expenses as medical consultant fees, court filing fees, service of process fees, expert witness fees, deposition costs, etc.
