Tex. R. Civ. P. 151
As amended through August 27, 2024
If the plaintiff dies, the heirs, or the administrator or executor of such decedent may appear and upon suggestion of such death being entered of record in open court, may be made plaintiff, and the suit shall proceed in his or their name. If no such appearance and suggestion be made within a reasonable time after the death of the plaintiff, the clerk upon the application of defendant, his agent or attorney, shall issue a scire facias for the heirs or the administrator or executor of such decedent, requiring him to appear and prosecute such suit. After service of such scire facias, should such heir or administrator or executor fail to enter appearance within the time provided, the defendant may have the suit dismissed.
