[14th Dist.] 1990, writ denied). However, the trial court properly considered counsel’s testimony as to the facts of his representation and found it to establish a reasonable fee of $13,000. In the absence of expert testimony, a trial court can take judicial notice of usual and customary attorney’s fees in a proceeding before the court without receiving further evidence. Tex.Civ.Prac. & Rem.Code Ann. § 38.004 (Vernon 1986). It is presumed that usual and customary attorney’s fees are reasonable, although the presumption may be rebutted. Id. at § 38.003. The award of reasonable attorney’s fees is mandatory under § 38.001 if there is proof of the reasonableness of the fees. See Caldwell & Hurst v. Myers, 714 S.W.2d 63, 65 (Tex.App.— Houston [14th Dist.] 1986, writ ref’d n.r.e.) (<HOLDING>). A court has the discretion to fix the amount
