Tex. Fam. Code §161.004
Termination Of Parental Rights After Denial Of Prior Petition To Terminate

The court may terminate the parent-child relationship after rendition of an order that previously denied termination of the parent-child relationship if: (1) the petition under this section is filed after the date the order denying termination was rendered; (2) the circumstances of the child, parent, sole managing conservator, possessory conservator, or other party affected by the order denying termination have materially and substantially changed since the date that the order was rendered; (3) the parent committed an act listed under Section 161.001 before the date the order denying termination was rendered; and (4) termination is in the best interest of the child.

At a hearing under this section, the court may consider evidence presented at a previous hearing in a suit for termination of the parent-child relationship of the parent with respect to the same child.
