In lawsuits where money is being claimed as damages, in lieu of other payment methods, a lawyer may agree to receive and a client may agree to pay a percentage of the case award, to be paid only if the case is won. The fee is contingent upon success; if the client does not prevail, the client owes no legal fees. In most states, it is not only required that a contingency fee agreement be used in accident type cases but also that the contingency fee agreement contain certain specific language and also that the actual fee percentage is established by court.
