All lawyers who handle injury cases handle them on a contingency fee, meaning you only pay if they recover money for you. This is not something special that the lawyer is doing just for you.The Florida Bar regulates how much an attorney working on a contingency case can charge you.
Typically the fees are 1/3 if the case resolves before a lawsuit is filed and 40% if it after a lawsuit is filed. Fees are capped at 25% when you are suing the government. Fees come off the gross amount before any other bills are paid.
In addition to attorney’s fees you must also pay costs. (These are items like copies of your medical records, hiring an expert, filing fees, court reporters, etc that are advanced by a lawyer to benefit your case) Costs are not included in fees.
