UCCJEA Temporary Emergency Jurisdiction Is Not Subject-Matter Jurisdiction (Preservation Required) and Endangerment Requires Child-Linked Proof

Case: In the Interest of K.N., K.L., K.L., and K.L., Children (Tex. June 5, 2026) (Hawkins, J.)

I. Introduction

This parental-termination case arises from repeated reports by a child’s school that the eldest child (“Karen”) was being physically and emotionally abused in the home. The Texas Department of Family and Protective Services (“the Department”) ultimately sought termination of Mother’s parental rights as to all four children and Father’s rights as to his three biological children (Kimberly, Kayla, and Keith). After the parents refused cooperation and later left Texas with the children for Louisiana, the Department obtained emergency orders and the children returned to Texas.

A jury found multiple predicate grounds for termination under Texas Family Code § 161.001(b)(1), including endangerment under Paragraphs (D) and (E), and made best-interest findings. The trial court terminated Mother’s rights only as to Karen (but not as to the younger three) and terminated Father’s rights as to his three children. The court also appointed the Department permanent managing conservator for the younger children, leaving Mother as possessory conservator.

On review, the Supreme Court of Texas confronted three central issues actually presented in the petitions:

• Whether an unpreserved challenge to UCCJEA “temporary emergency jurisdiction” under Texas Family Code § 152.204(a) can be raised for the first time in the Supreme Court as a subject-matter jurisdiction defect.
• Whether clear-and-convincing evidence supported endangerment predicates under § 161.001(b)(1)(D) and (E) as to Mother (Karen) and as to Father (his three children).
• Whether the evidence supported appointing the Department (not Mother) as managing conservator for the younger three children.

II. Summary of the Opinion

III. Analysis

A. The Decision’s Most New “Rule”: UCCJEA § 152.204(a) Does Not Implicate Subject-Matter Jurisdiction

The parents argued (for the first time in the Supreme Court) that the trial court’s orders were “void” because the children were in Louisiana—not “present in this state”—when the protective order issued, purportedly defeating Texas Family Code § 152.204(a) “temporary emergency jurisdiction.”

The Court reframed the dispute as a threshold doctrinal question: does § 152.204(a) create a true subject-matter jurisdiction limit (non-waivable, voidness-producing), or is it a non-jurisdictional statutory prerequisite (waivable/forfeitable, typically yielding voidable consequences at most)?

In applying that rule, the Court reasons:

• Textual silence: § 152.204(a) does not expressly speak in subject-matter terms, mandate dismissal, or otherwise specify voidness as a remedy.
• Context and function of the UCCJEA: The UCCJEA is designed to prevent simultaneous multi-state custody litigation and to prioritize the “home state” forum—i.e., it is largely about allocation/prioritization among states, not about whether Texas courts have the inherent power to hear custody disputes at all.
• Features inconsistent with subject-matter jurisdiction: The statutory scheme allows party agreement about which state should proceed (Texas Family Code § 152.207(b)(5)) and permits a court to decline jurisdiction for convenience (Texas Family Code § 152.207(a)). Subject-matter jurisdiction cannot be conferred by consent or waived, and it is not a “convenience” concept.
• Legislative use of “voidable” elsewhere: Texas Family Code § 155.104(b) characterizes certain defects (lack of continuing exclusive jurisdiction) as “voidable,” not “void,” reinforcing the notion that UCCJEA-type defects are not “genuine subject-matter jurisdiction” defects.
• Stability/finality concerns in child cases: The Court emphasizes “expediency and stability” in custody matters and resistance to “procedural gamesmanship.” This backdrop strengthens the impulse to require preservation unless the Legislature unmistakably commands otherwise.

Practical consequence: A parent who believes a Texas court wrongly invoked § 152.204(a) must raise that complaint in the trial court (and preserve it) if they want appellate review. Labeling it “jurisdictional” will not rescue the issue later.

B. Endangerment (D) and (E): The Court’s Tightened Fit Between Proof and Child-Specific Risk

1. Mother (as to Karen): Sufficient evidence of both “conditions/surroundings” and “conduct” endangerment

The Court affirms the sufficiency of evidence supporting § 161.001(b)(1)(D) and (E) as to Mother’s treatment of Karen. The record included multi-year reports and testimony supporting:

• Physical harm (bruises, belt marks; dragging by hair; shoulder injury; painful punishments like kneeling on rice).
• Food deprivation and differential treatment (Karen not permitted to “eat like the other” children; reports of hunger and being denied food or forced to eat separately).
• Emotional/psychological abuse (extended isolation; wall-facing punishments for “hours” or “days”; fear of Mother; threats of foster placement to deter disclosure).

Notably, the Court highlights that critical testimony came from Mother’s own close relatives (Grandmother and Mother’s sister), lending the jury a basis to view the abuse reports as credible and not merely adversarial accusations.

2. An express caution: lawful corporal punishment is not, by itself, termination-worthy

While affirming Mother’s termination as to Karen, the Court cautions lower courts not to equate “traditional” discipline with endangerment. Citing Texas Family Code § 151.001(e)(1), it emphasizes that “reasonable discipline” may include corporal punishment, and it distinguishes that from “cruel, outrageous, and vicious” violence (invoking Stanfield v. State).

This passage functions as an appellate “guardrail”: termination must rest on proof of endangerment, not generalized disapproval of parenting styles that the Legislature has deemed lawful.

3. Father (as to his three children): Insufficient evidence of endangerment under (D) and (E)

The Court reverses the endangerment findings as to Father under § 161.001(b)(1)(D) and (E), rejecting four theories advanced by the Department:

• (i) “Failure to protect” from Mother’s abuse of Karen
  The Court holds the record did not show Father’s children were abused, nor that mere exposure to Mother’s abuse of a stepchild automatically establishes endangerment of Father’s children. It stresses the case’s distinctive fact: Karen was singled out for uniquely abusive treatment, and Father’s parental rights to Karen were not at issue.
  Comparative precedent: In re J.W. is used to illustrate that even where a father failed to protect his own child from the mother’s abuse, endangerment proof may still be insufficient; here, the link is weaker.
• (ii) Father’s post-removal Louisiana crimes (high-speed chase; meth possession)
  Citing In re J.F.-G. and Tex. Dep't of Hum. Servs. v. Boyd, the Court reiterates that criminality may support termination when it is part of a “course of conduct” that endangers the child. But isolated misconduct—especially after the children are already removed and in another state—did not meet that burden here. The Department did not build the evidentiary bridge required by In re E.N.C. (details of offense + voluntary course of conduct + endangering effect on children).
• (iii) Post-removal drug test (amphetamine) and refusal to verify prescription
  The Court recognizes that drug use can be endangering (citing In re R.R.A., In re J.O.A., In re A.V.) but emphasizes its recent caution from In re R.R.A.: “illegal drug use alone may not be sufficient” without additional evidence showing risk to the parent’s ability to parent. Here, the Department did not connect the drug evidence to parenting-time danger, a pattern of use, or child-impact.
• (iv) “Little effort at reunification”
  The Court treats this as largely belonging (if anywhere) under other predicates (notably the since-repealed Paragraph (O) service-plan predicate), and finds the Department did not explain why low reunification effort constitutes endangerment under (D) or (E) on this record.

The Court’s bottom line is a demand for child-linked proof: endangerment under (D) and (E) requires evidence that the parent’s conduct or the child’s environment posed a real, non-speculative threat to the child’s physical or emotional well-being, not merely proof of a parent’s bad acts in the abstract—particularly when those acts occur after removal.

C. Conservatorship: “Significant Impairment” and Deference to Trial Courts—But With a Remand-Driven Reassessment

Because Mother’s rights to the younger children were not terminated, the relevant dispute becomes conservatorship (who should be managing conservator). The Court applies:

• Texas Family Code § 153.131(a) (parental presumption; rebuttal by proof that parental appointment would “significantly impair” the child),
• In re J.A.J. (contrasting termination’s enumerated predicate grounds with conservatorship’s “significant impairment” standard),
• Lewelling v. Lewelling (need evidence of specific injurious acts/omissions), and
• abuse-of-discretion review per Gillespie v. Gillespie.

The Court upholds the trial court’s choice not to appoint Mother as managing conservator on evidence including: her abuse of Karen; threats to school personnel and resulting indictment (with Danet v. Bhan referenced for considering criminal misconduct); children’s medical/dental neglect; and Mother’s minimal contact after removal.

But it simultaneously recognizes conservatorship here is intertwined with Father’s parental status. Because Father won reversal on (D) and (E), the Court directs that managing conservatorship be reassessed on remand after the court of appeals addresses the remaining termination predicates as to Father.

D. The Court’s Approach to New Texas Constitution art. I, § 37 (“Parental Rights and Responsibilities”)

The Court acknowledges the 2025 ratification of Texas Constitution art. I, § 37 and requested supplemental briefing. Yet it expressly declines to define the provision’s operational legal standards, emphasizing institutional caution: the Supreme Court is “a court of review, not of first view,” especially on novel constitutional questions.

In doing so, it invokes a line of cases about percolation and remand-first discipline, including 1 Coventry Ct., LLC v. Downs of Hillcrest Residential Ass'n, City of San Antonio v. Realme, In re Troy S. Poe Tr., Rattray v. City of Brownsville, and Point Energy Partners Permian, LLC v. MRC Permian Co. (with Tex. Comm'n on Env't Quality v. Maverick County also cited in that discussion), as well as the “competing understandings” percolation theme drawn from Perez v. City of San Antonio.

Doctrinally, this is a “holding by restraint”: it signals that § 37 is important and potentially consequential, but that litigants should develop § 37 arguments in the trial court and court of appeals, where competing interpretations can be tested before reaching the court of last resort.

E. Standards of Review: Reinforcing “Clear and Convincing” Rigor While Deferring to Juries on Credibility

Echoing its companion opinion In re H.S., the Court foregrounds the “strong presumption” against termination and the “last resort” posture. Yet it also reaffirms that appellate courts do not re-try credibility: it cites In re J.F.C. for legal-sufficiency review under clear and convincing evidence and City of Keller v. Wilson for deference to the factfinder on credibility conflicts.

The opinion also includes a notable meta-instruction about appellate writing: relying on In re A.M. (Blacklock, J., concurring in denial), it discourages “kitchen-sink” evidentiary recitations that may mislead lower courts about what evidence actually “does the work.”

IV. Precedents Cited (and How They Shape the Outcome)

1. Jurisdiction, preservation, and the “clear-statement” approach

• Rush Truck Ctrs. of Tex., L.P. v. Sayre and Steel Co. v. Citizens for a Better Env't: jurisdiction must be addressed first.
• Tex. Right to Life v. Van Stean, Bland Indep. Sch. Dist. v. Blue, United Servs. Auto. Ass'n: frame “subject-matter jurisdiction” as the court’s power to decide the case, and warn of “jurisdiction” being used imprecisely.
• Dubai Petroleum Co. v. Kazi and Tex. Disposal Sys. Landfill, Inc. v. Travis Cent. Appraisal Dist.: anchor the clear-statement rule and the difference between jurisdiction and “statutory prerequisites.”
• Morales v. Liberty Mut. Ins. Co.: absence of dismissal remedy suggests non-jurisdictional intent.
• Powell v. Stover and In re D.S.: supply UCCJEA purpose (multi-state conflict avoidance) and reinforce stability and anti-manipulation in custody disputes.
• In re K.S.L.: highlights the harm of uncertainty/delay in child placements, supporting the preservation requirement.
• Mapco, Inc. v. Forrest: reinforces void vs voidable distinction central to rejecting subject-matter framing.

2. Fundamental parental rights backdrop

• Mahmoud v. Taylor, Troxel v. Granville, Wisconsin v. Yoder, Pierce v. Soc'y of Sisters, Meyer v. Nebraska, Wiley v. Spratlan, Holick v. Smith: establish parental rights as fundamental (federal and Texas) and provide the constitutional gravity justifying strict termination standards.

3. Termination proof standards

• In re G.M. and State v. Addington: define “clear and convincing evidence” as producing a “firm belief or conviction.”
• In re J.F.C.: governs legal sufficiency under clear and convincing (view evidence in light favorable to finding, assume factfinder resolved disputes, disregard evidence it could disbelieve).

4. Endangerment doctrine, criminality, and drugs

• In re J.W.: used to show that “failure to protect” theories require careful proof; mere relational proximity to abuse does not automatically establish endangerment.
• In re J.F.-G. and Tex. Dep't of Hum. Servs. v. Boyd: criminal conduct can support termination when part of a “course of conduct” that endangers; incarceration alone is insufficient.
• In re E.N.C.: requires evidence connecting the offense(s) to a voluntary course of conduct that endangered children.
• In re C.E.: emphasizes the relevant timeframe for (E) commonly centers on when the parent was the caregiver, informing skepticism about post-removal evidence.
• In re R.R.A., In re J.O.A., In re A.V.: drug use can be endangering, but typically through pattern/parenting impairment/child-linked danger; “drug use alone” may not suffice without more.

5. Conservatorship standards

• In re J.A.J.: frames “significant impairment” as distinct from termination predicates, and confirms abuse-of-discretion review.
• Lewelling v. Lewelling: requires proof of specific injurious acts/omissions.
• Gillespie v. Gillespie: anchors abuse-of-discretion review for conservatorship determinations.
• Danet v. Bhan: criminal misconduct may be relevant to conservatorship decisions.
• In re S.T. and In re S.D.: a parent’s treatment of other children and neglect can be relevant to conservatorship.

6. Institutional restraint and remand practice

• 1 Coventry Ct., LLC v. Downs of Hillcrest Residential Ass'n, City of San Antonio v. Realme, In re Troy S. Poe Tr., Point Energy Partners Permian, LLC v. MRC Permian Co., Perez v. City of San Antonio, Rattray v. City of Brownsville: support the Court’s choice not to define new constitutional § 37 “first” and to remand unaddressed grounds.
• In re N.L.S.: cited with the remand principle where issues were raised but not decided below.

V. Complex Concepts Simplified

• Subject-matter jurisdiction vs “jurisdictional-sounding” statutes: Subject-matter jurisdiction is the court’s basic power to hear the type of case. If it’s missing, judgments are typically “void” and can be attacked anytime. Many statutes use the word “jurisdiction” but actually set procedural or substantive prerequisites that must be raised and preserved; failure to comply may make an order reversible or voidable—not void.
• UCCJEA “temporary emergency jurisdiction” (Texas Family Code § 152.204): A mechanism allowing a state court to act quickly to protect a child in emergencies, while the broader UCCJEA scheme coordinates which state should ultimately decide custody. Here, the Court treats § 152.204(a)’s “present in this state” condition as non-subject-matter and therefore waivable/forfeitable if not raised.
• Termination predicate grounds (D) vs (E): Paragraph (D) focuses on endangering conditions or surroundings the parent knowingly causes/allows. Paragraph (E) focuses on endangering conduct by the parent (or knowingly placing the child with others who engage in such conduct). Both require endangerment to the child’s physical or emotional well-being.
• “Clear and convincing” proof: More than “more likely than not,” less than “beyond a reasonable doubt,” and requires evidence that could produce a firm belief or conviction. On appeal, courts defer to juries on credibility but test whether the evidence could reach that firm-belief threshold.
• Conservatorship terms: A managing conservator typically holds primary decision-making authority. A possessory conservator typically has visitation/possession rights but fewer decision-making powers. The law presumes parents should be managing conservators unless it would significantly impair the child.
• “Fictive kin”: Non-relatives with a family-like relationship to the children who may provide placement and may seek adoption.

VI. Conclusion

This opinion’s most consequential doctrinal contribution is jurisdictional: Texas Family Code § 152.204(a) does not implicate subject-matter jurisdiction, so UCCJEA “temporary emergency jurisdiction” objections—such as whether children were “present in this state”—must be preserved in the trial court and cannot be raised for the first time on petition for review as voidness challenges.

On the merits, the Court illustrates a two-track sufficiency analysis under the clear-and-convincing standard: it affirms termination when the record demonstrates sustained, child-specific physical and emotional abuse (Mother as to Karen), but reverses where the Department’s theories do not adequately connect a parent’s alleged failures, post-removal crimes, or drug evidence to a course of conduct endangering the particular children at issue (Father as to his three children under (D) and (E)).

Finally, the Court signals that Texas Constitution art. I, § 37 will matter, but insists that its interpretation should emerge through lower-court development rather than immediate statewide pronouncement in a single case record—an institutional choice likely to shape how § 37 litigation is framed and preserved going forward.
