Can I get mandamus relief if the trial court makes the wrong decision in my child custody case?

Q: Can I get mandamus relief if the trial court makes the wrong decision in my child custody case?

In re J. T. J.: A close familial bond is not enough to grant grandparents legal standing in Texas; they must provide specific facts showing that a lack of access will cause documented physical or clinical emotional harm to the child. | In Re Yaneth Lopez: A mandatory venue statute does not guarantee mandamus relief; practitioners must meticulously curate the appellate record, including all supporting affidavits and hearing transcripts, to affirmatively prove the trial court's abuse of discretion.

This question has been addressed in 2 Texas court opinions:

In re J. T. J.

COA03 — February 11, 2026

In this case, paternal grandparents intervened in a custody dispute seeking court-ordered access to their grandchild. They provided affidavits detailing a deep bond, including homeschooling the child and taking him on vacations. The child's mother challenged their standing, arguing they failed to meet the strict legal requirements of the Texas Family Code. The Court of Appeals agreed with the mother, ruling that grandparents must prove that denying access would "significantly impair" the child's physical health or emotional well-being. The court held that evidence of a close relationship and "unavoidable sadness" from separation is not enough to overcome the legal presumption that a fit parent acts in their child's best interest.

Litigation Takeaway

“A close familial bond is not enough to grant grandparents legal standing in Texas; they must provide specific facts showing that a lack of access will cause documented physical or clinical emotional harm to the child.”

In Re Yaneth Lopez

COA13 — February 17, 2026

In this SAPCR proceeding, Relator Yaneth Lopez sought a mandatory venue transfer under Texas Family Code § 155.201(b), arguing the child had resided in a different county for six months and that the opposing party failed to file a controverting affidavit. The trial court denied the motion. On review, the Thirteenth Court of Appeals analyzed the request under the standard mandamus framework, noting that while venue transfers are often mandatory, the Relator still carries the burden of providing a sufficient record under Texas Rule of Appellate Procedure 52 to prove a clear abuse of discretion. The Court held that because the Relator failed to provide an adequate record establishing the trial court's error or the lack of an adequate remedy on appeal, the petition for writ of mandamus must be denied.

Litigation Takeaway

“A mandatory venue statute does not guarantee mandamus relief; practitioners must meticulously curate the appellate record, including all supporting affidavits and hearing transcripts, to affirmatively prove the trial court's abuse of discretion.”
