On Confession of Error
Upon the state’s laudable confession of error, this case is reversed and remanded in order for the lower court to either hold an evidentiary hearing or to attach por*1127tions of the record that conclusively refute Appellant’s claims.
As conceded by the state, Appellant’s Florida Rule of Criminal Procedure 3.850 motion challenged the voluntariness of his plea, a claim properly cognizable in a 3.850 motion. Mikenas v. State, 460 So.2d 359 (Fla.1984). As a result, the trial court was required to attach evidence conclusively refuting such a claim. See, e.g., Barnes v. State, 124 So.3d 904, 915 (Fla.2013); Barnes v. State, 801 So.2d 989 (Fla. 1st DCA 2001) (reversing summary denial of 3.850 motion where defendant alleged plea was involuntary due to mental'illness and court failed to attach documents that' conclusively refuted his " claims); Young v. State, 789 So.2d 1160, 1162 (Fla. 5th DCA 2001) (“absent a transcript of the plea hearing, Young’s claim that his plea was unknowing has not been conclusively refuted by the record. Thus, as to this claim, we reverse and remand for -further proceedings.”).
Moreover, because Appellant’s claims must be taken as true, Appellant was entitled to the presumption of incompetency. Alexander v. State, 380 So.2d 1188, 1190 (Fla. 5th DCA 1980) (once adjudicated incompetent, a hearing .on whether competency has been restored cannot be waived); King v. State, 387 So.2d 463, 464 (Fla. 1st DCA 1980) (“In Florida, if a person is adjudicated to be mentally incompetent, it is presumed he continues to be so until it is shown his sanity has returned"). Moreover, this presumption shifts the burden of proving competency to the state. Wells v. State, 98 So.2d 795 (Fla.1957). In its initial response below, the state failed to address the question of incompetency. Upon remand, the trial court should require the state to adequately respond to Appellant’s claims of incompetency.
Accordingly, we reverse and remand for the trial court to consider Appellant’s claims of incompetence under the presumption of incompetence and to provide evidentiary support for its-conclusions on those claims.
Reversed and remanded.
