FERGUSON, Judge.
A written contract will not be reformed on the basis of a unilateral mistake absent clear and convincing proof of fraud or inequitable conduct by the other side. Camichos v. Diana Stores Corp., 157 Fla. 349, 25 So.2d 864 (1946); Hopkins v. Mills, 116 Fla. 550, 156 So. 532 (1934). Where no evidence was presented in a non-jury trial to establish a prima facie case, it was proper to grant defendant's motion, made at the conclusion of the plaintiff's case, for involuntary dismissal pursuant to Florida Rules of Civil Procedure 1.420(b).
