Tex. R. App. P. 27.2
As amended through February 20, 2024
The appellate court may treat actions taken before an appealable order is signed as relating to an appeal of that order and give them effect as if they had been taken after the order was signed. The appellate court may allow an appealed order that is not final to be modified so as to be made final and may allow the modified order and all proceedings relating to it to be included in a supplemental record.
