2. Foster Parent Intervention Limited

Tex. Fam. Code § 102.004(b) allows persons with substantial past contact with a child leave to intervene in a pending suit if they can provide satisfactory proof to the court that the appointment of a parent as Sole Managing Conservator or both parents as Joint Managing Conservators would significantly impair the child's physical health or emotional development. However, a foster parent may only be granted leave to intervene under Tex. Fam. Code § 102.004(b) if the foster parent would have standing to file an original suit as provided by Tex. Fam.
