Case costs are different from attorney's fees. The law firm will incur costs in order to prosecute the case, as for example, on investigation; obtaining police, medical, and other records; hiring experts; court costs; and the like. In most personal injury cases, the firm will agree to advance the case costs, and these costs will be reimbursed to the firm out of the financial recovery. If the firm agrees to this arrangement, you will not be charged for case costs unless there is a financial recovery.
