RULE 78. PETITION: ORIGINAL AND SUPPLEMENTAL; INDORSEMENT
The pleading of plaintiff shall consist of an original petition, and such supplemental petitions as may be necessary in the course of pleading by the parties to the suit. The original petition and the supplemental petitions shall be indorsed, so as to show their respective positions in the process of pleading, as "original petition," "plaintiff's first supplemental petition," "plaintiff's second supplemental petition," and so on, to be successively numbered, named, and indorsed.

(a) Requirement. A civil case information sheet, in the form promulgated by the Supreme Court of Texas, must accompany the filing of:
(1) an original petition; and
(2) a post–judgment motion for modification or enforcement in a case arising under the Family Code.
(b) Signature. The civil case information sheet must be signed by the attorney for the party filing the pleading or by the party.
(c) Enforcement. The court and clerk must take appropriate measures to enforce this rule. But the clerk may not reject a pleading because the pleading is not accompanied by a civil case information sheet.
(d) Limitation on Use. The civil case information sheet is for data collection for statistical and administrative purposes and does not affect any substantive right.

The petition shall state the names of the parties and their residences, if known, together with the contents prescribed in Rule 47 above.
