What is a contingency legal fee?

It is a fee paid to the attorney after the case has been successfully settled or litigated. It is usually based on the gross amount collected. The attorney does not charge for his time or expenses unless he is successful in collecting compensation for the client. This type of fee allows the client to pay nothing upfront and to transfer the risk to the attorney regarding the outcome of the case. Most clients highly prefer a case to be on a contingency fee basis.
