Almost all personal injury attorneys work on cases without requiring a retainer and collect their attorney fee as a percentage of any settlement or verdict they obtain for you. If you get nothing from the case, neither does the attorney. Attorney’s fees are contingent on success and are usually 33% of the amount recovered. However, under some circumstances a slightly lower attorney fee may be charged. Any costs incurred in pursuing the claim will generally be advanced by the attorney and paid for at the conclusion of the case.
