(a) In a civil action, including a probate or guardianship proceeding, filed in a district court, a county court, a statutory county court, a statutory probate court, or the business court, each party or the party's attorney shall include in its initial pleading:
(1) the last three numbers of the party's driver's license number, if the party has been issued a driver's license; and
(2) the last three numbers of the party's social security number, if the party has been issued a social security number.
(b) A court may, on its own motion or the motion of a party, order that an initial pleading be amended to contain the information listed under Subsection (a) if the court determines that the pleading does not contain that information. A court may find a party in contempt if the party does not amend the pleading as ordered by the court under this subsection.
