298 S.W.3d 726, 733 (Tex.App.-Austin, 2009, no pet.) (reversing default judgment because wife failed to give husband fair notice' that her amended petition sought permanent rather than temporary relief).' “More onerous” is anything that exposes the defendant to additional liability. Id. at 733-34; see also Caprock Constr. Co. v. Guaranteed Floorcovering, Inc., 950 S.W.2d 203, 204 (Tex.App.-Dallas 1997, no writ). Here, Timothy did not have fair notice that he was exposed to the additional liability of post-divorce spousal maintenance because nothing in Kelly’s pleadings indicated she sought such relief. By granting relief more onerous than that Kelly requested in ‘ her petition, the trial court erred, and that error is apparent oh the face of the record. See Flowers, 407 S.W.3d at 458 (<HOLDING>); Binder v. Joe, 193 S.W.3d 29, 33
