Can a lease agreement permit a plaintiff to recover reasonable attorney fees in an action between the parties?

Under a "lease agreement permit[ting] recovery of reasonable attorney fees in an action between the parties[,] . . . an interpretation which bars recovery to parties who have contingent fee agreements would create a great deal of inequity because although a party with a contingent fee agreement would be exposed to the risk of paying fees incurred by an opponent, he would have no opportunity to recover any portion of the fees he would in fact be required to pay if he were successful. Such disparity of treatment is to be avoided in interpreting and applying attorney fees provisions. [Citation.]" (Gonzales v. Personal Storage, Inc. (1997) 56 Cal.App.4th 464, 480.)
