Texas Request For Process is a legal document used in Texas to begin the process of serving notice of a lawsuit on a defendant. It is typically served by a process server or constable. This document includes the plaintiff's name, the plaintiff's attorney's name, the defendant's name, the cause of action, and the court's address. There are two types of Texas Request For Process: citation by publication and citation by posting. Citation by publication is used when the defendant's address is unknown, and requires that notice of the lawsuit be published in a newspaper. Citation by posting is used when the defendant's address is known, and requires that notice of the lawsuit be posted on the defendant's door.
