In Go Leasing, Inc. v. Groos National Bank, 628 S.W.2d 143, 144 (Tex. App.--San Antonio 1982, no writ), a party obtaining a judgment filed a motion nunc pro tunc which was later recognized--there by the appellate court--to have been a motion to modify the judgment. Id. at 144.
The trial court granted the motion within 30 days of the judgment, and the appellate court--while noting that "considerations of professionalism should prompt counsel to make an effort to notify other interested parties that he intends to ask the court to modify the judgment"--held that the judgment was valid because no notice had been required for a motion to modify or for a ruling thereon at any time within 30 days of the final judgment. Id. at 144, 144 n.2.
