Texas Supplemental Instructions for Self-Represented Litigants (SISAL) is a document created to help individuals who are representing themselves in civil courts. SISAL is designed to provide self-represented litigants with an overview of the legal process in Texas, as well as the necessary steps and forms needed to file a case in court. SISAL includes instructions on how to file a lawsuit, how to serve a defendant, the rules of evidence, and other relevant information. SISAL also includes directions and forms for filing and responding to motions, subpoenas, and requests for discovery. There are four different types of SISAL: General Instructions, County or District Court Specific Instructions, Family Law Specific Instructions, and Justice Court Specific Instructions.
