Unnecessary Hague Return Observations Cannot Become Findings in Later Welfare Proceedings
Case: X & Y (Child Arrangements: Findings) [2026] EWCA Civ 1169
Court: Court of Appeal of England and Wales, Civil Division
Date: 10 September 2026
Judges: Lord Justice Baker, Lord Justice Phillips and Lady Justice Falk
1. Introduction
This decision draws an important boundary between summary international child abduction proceedings and subsequent proceedings determining children’s long-term welfare. Observations about disputed parental behaviour, unnecessary to the determination of a Hague Convention return application and made without testing the parents’ accounts through cross-examination, could not properly become established findings in later child arrangements proceedings.
The dispute concerned two young children, X and Y. The father sought arrangements under which the children would live with him in England. The mother sought permission for them to live with her in State A, where they had attended school. Their competing allegations included coercive control, excessive drinking, a disputed physical assault and the father’s alleged manipulation of X’s relationship with the mother.
The Court of Appeal unanimously allowed the father’s appeal against Hayden J’s final child arrangements decision. Its central concern was not which parent’s account was ultimately correct, but whether the factual foundation for the welfare decision had been established fairly. The court ordered a complete rehearing before another judge, while separately making protective interim arrangements.
2. Background and Procedural History
The family had moved to State A following the mother’s appointment to an overseas role. After the parental relationship deteriorated, both parents and the children returned to England. The father applied for child arrangements and associated protective orders. The mother subsequently applied under the Hague Child Abduction Convention for the children’s summary return to State A.
The Children Act proceedings were stayed while the Convention application was determined. In those proceedings, the father disputed that the children were habitually resident in State A and also relied on their objections to returning and the alleged risk of harm on return.
Hayden J dismissed the Convention application because the children had remained habitually resident in England and Wales. However, his judgment also contained extensive observations about the parents’ conduct. These included conclusions that the father had exaggerated and exploited the mother’s drinking, behaved in a controlling manner and negatively influenced X’s view of her.
Those observations subsequently became central to the Children Act proceedings. The children’s guardian treated them as findings and regarded the father’s failure to accept or reflect on them as relevant to his parenting capacity. The judge similarly approached the later hearing as an inquiry into whether the father’s behaviour had continued, rather than determining the underlying disputed allegations afresh.
Following oral evidence in August 2026, Hayden J ordered that both children should live with the mother in State A. He considered that X needed distance from the father’s influence and envisaged a period of little or no contact between them. Separately, he found that the alleged physical assault had not occurred and that the mother had used the allegation to divert attention from her drinking.
The father obtained an urgent appellate stay of the relocation order. The appeal was then expedited so that arrangements could be settled before, or shortly after, the beginning of the school term.
3. Summary of the Judgment
Lord Justice Baker gave the substantive judgment, with which Lord Justice Phillips and Lady Justice Falk agreed. The principal conclusions were:
- The Convention observations were not established findings for the later proceedings. They concerned allegations with no discernible relevance to habitual residence, the only issue actually decided in the Convention application.
- The subsequent evidence had not been assessed afresh. Although the parents were cross-examined at the Children Act hearing, their evidence was evaluated against an assumed foundation of earlier findings.
- That approach risked reversing the burden of proof. The father should not have been required to disprove allegations because of impressions expressed in the earlier judgment.
- The evidence had been considered in the wrong sequence and in separate compartments. The disputed assault and the mother’s drinking were relevant to understanding X’s attitude and the allegations of coercive control and alienating behaviour.
- The decision and findings had to be set aside. Both parents’ Children Act applications required a complete rehearing before another Family Division judge.
The appeal succeeded on the father’s fourth ground: inappropriate reliance on supposed findings from the Convention proceedings. The court did not determine his remaining grounds or the mother’s challenge to the findings concerning the alleged assault. Those findings were themselves displaced by the requirement for a complete rehearing.
The outcome was therefore not an appellate finding that either parent’s substantive allegations were true or false.
4. The Governing Legal Framework
4.1 Hague proceedings and welfare proceedings serve different purposes
The Convention provides a summary mechanism addressing the return of children following alleged wrongful removal or retention. It does not ordinarily determine their long-term living arrangements.
Article 16 suspends the requested state’s adjudication of custody merits until it has been determined that the child is not to be returned under the Convention. Section 9 of, and Schedule 3 to, the Child Abduction and Custody Act 1985 give domestic effect to that restriction, including its application to child arrangements orders.
Here, the allegations about drinking, coercive control and X’s attitudes might have become relevant to the father’s Convention objections if the jurisdictional basis for return had been established. Once the judge decided that the children remained habitually resident in England and Wales, those further issues did not require determination.
4.2 Evidence must remain proportionate to the Convention issues
The Practice Guidance, Case Management and Mediation of International Child Abduction Proceedings, dated 1 March 2023, requires economical witness statements confined to relevant factual matters. It also makes oral evidence exceptional unless necessary to resolve the proceedings justly.
The parties’ submission of extensive evidence did not enlarge either the scope of the application or the court’s powers. A large evidential record does not convert summary return proceedings into a comprehensive welfare trial.
4.3 Welfare decisions require their own proper factual foundation
Under the Children Act 1989, the children’s welfare was the paramount consideration. That assessment depended on understanding disputed conduct and its effect on each child. Given the nature of the allegations, the parents required a proper opportunity to challenge the evidence through cross-examination.
The Convention hearing had included oral evidence from the Cafcass officer, but neither parent had given oral evidence. The crucial parental allegations had therefore not been tested in that way.
5. Precedents Cited and Their Significance
5.1 Re B (Children) [2008] UKHL 35
Hayden J cited this authority when addressing the burden and standard of proof concerning the alleged assault. It establishes the relevant distinction between proving an allegation on the balance of probabilities and resolving uncertainty through the allocation of the burden of proof.
The trial judge went beyond finding that the mother had failed to prove an assault. He positively found that no assault had occurred and attributed a particular motive to her allegation. The mother challenged both conclusions.
The Court of Appeal did not determine whether that application of the evidential principles was sustainable. Its broader conclusion required all the Children Act findings to be reconsidered. The authority nevertheless highlights an important distinction: an unproved allegation is not automatically a proved fabrication. Whether either positive finding was justified remained for the rehearing.
5.2 Re Y (Experts and Alienating Behaviour: The Modern Approach) [2026] EWFC 38, [2026] 3 All ER 686
The father relied on this decision, in which Sir Andrew McFarlane P endorsed the Family Justice Council’s December 2024 guidance on children’s unexplained reluctance, resistance or refusal to spend time with a parent and allegations of alienating behaviour.
The passage quoted in the appeal explains that, where domestic abuse and alienating behaviour are both alleged and fact-finding is required, the court must first determine the relevant domestic abuse issues. It must then consider whether the child’s response is an “appropriate justified reaction”, or is explained by protective behaviour or trauma, rather than prematurely attributing it to manipulation.
The Court of Appeal found force in the submission that Hayden J’s approach departed from this method. The alleged assault and the mother’s drinking potentially helped explain X’s attitude. They needed proper evaluation before conclusions were reached about the father’s responsibility for that attitude.
This was not a finding that X’s rejection of the mother was justified. It was a requirement to establish the relevant underlying facts before choosing between competing explanations.
This authority supplied the wider evidential principle underlying the court’s reasoning. Butler-Sloss LJ stated:
“Evidence cannot be evaluated and assessed in separate compartments.”
A judge must consider each piece of evidence in relation to the others and maintain an overview of the whole evidential picture. Here, conclusions about the father’s influence on X were reached before the alleged assault was determined. The later assault findings, if correct, could materially affect the interpretation of what either parent had told X.
The significance of Re T extends beyond alienating behaviour. Interconnected allegations cannot safely be resolved through isolated assessments that omit their implications for one another.
5.4 Re F (A Child) (Habitual Residence) [2025] EWCA Civ 911
The guardian cited this decision in support of the proposition that judges may make findings in Convention proceedings. The Court of Appeal accepted that general proposition: in appropriate circumstances, such findings are both permissible and necessary.
The decisive distinction was between findings needed to resolve Convention issues and observations about matters that did not require decision. The present judgment therefore does not establish that findings from Convention proceedings can never carry weight later.
5.5 TMS v AVS [2023] EWHC 1620 (Fam)
The guardian also relied on paragraphs 29–31 of this decision of Williams J to support the court’s ability to make findings in Convention proceedings. Again, the Court of Appeal did not reject that general power.
Neither this authority nor Re F (A Child) (Habitual Residence) answered the particular problem: the observations here were unnecessary to the habitual residence decision and had not resulted from the evidential process required for the subsequent disputed welfare issues.
5.6 Volpi v Volpi [2022] EWCA Civ 464
The guardian invoked this authority to argue against appellate interference with findings supported by the overall evidence. It represented the familiar restraint exercised by appellate courts when reviewing a trial judge’s factual assessment.
However, the appeal concerned more than disagreement over evidential weight. The later assessment had proceeded from an improper starting point and risked shifting the burden of proof. Appellate restraint did not prevent intervention where the factual decision-making process itself was flawed.
6. Analysis of the Court’s Reasoning
6.1 Judicial impressions do not acquire authority merely through repetition
The central question was the status of the earlier observations, not their firmness of expression. Lord Justice Baker considered them impressions of the written material rather than findings necessary to resolve the proceedings.
The distinction had practical consequences. The guardian assessed the father’s lack of acceptance as a parenting concern, while the judge treated the later inquiry as addressing “continuing” conduct. This gave the observations an authority they did not possess.
The court held that they had no status and should have attracted no weight in the Children Act assessment. That did not exclude the underlying statements, messages or recordings from fresh consideration. It meant that the judge’s previous interpretation could not substitute for determining what that evidence established.
6.2 The failure to appeal did not validate the observations
The mother and guardian argued that the father had not appealed the Convention findings. The court rejected that argument because the relevant observations were not findings in the necessary sense.
A party’s failure to challenge unnecessary judicial commentary does not transform it into an established factual platform for different proceedings.
6.3 Later cross-examination did not cure the defective starting point
The parents were questioned about many relevant issues at the Children Act hearing. Nevertheless, the evidence was not assessed de novo. It was considered against propositions already regarded as established.
The suggestion that the father could have persuaded the judge that the earlier findings were wrong exposed the unfairness. The mother’s allegations remained hers to prove; the father did not carry a new burden of disproving them.
6.4 The drinking evidence required contextual reassessment
The mother’s oral admissions went materially further than the judge’s earlier assessment of her drinking. She also accepted that the father had objectively justifiable grounds for concern.
That development mattered to allegations that his concern was exaggerated, controlling or manipulative. It did not necessarily disprove those allegations: genuine concern and abusive conduct are not logically incompatible. But it required an integrated assessment of the drinking, the father’s response and the children’s experiences, without treating the earlier interpretation as settled.
6.5 Findings about the alleged assault could not be isolated
The guardian had herself explained why the assault allegation mattered to X’s understanding of the separation. Depending on what had happened, either parent’s account to X might have had a substantially different meaning.
The court therefore considered that the incident should have been determined before conclusions were reached about parental influence. It was also potentially relevant to the coercive control allegations.
This does not mean that telling a child something factually accurate is necessarily appropriate. The point was that truth, context and the manner of involving the child all required examination together.
6.6 A complete rehearing was necessary
The father unsuccessfully suggested that the finding rejecting the assault allegation might survive. That would have preserved one part of an assessment the court had found insufficiently integrated.
The remedy was therefore comprehensive. Neither parent could retain favourable findings while requiring the interconnected allegations against them to be reconsidered.
7. Interim Arrangements: Protection Without Prejudgment
Setting aside the final decision did not remove the need to decide immediately where the children should live and attend school. The Court of Appeal made that decision independently under the welfare principle and Practice Direction 12J.
Paragraphs 25–27 of PD12J require particular care where domestic abuse allegations remain unresolved. An interim order must serve the child’s interests and must not expose the child or the other parent to an unmanageable risk of harm. Coercive or controlling behaviour falls within the relevant definition of domestic abuse.
The court considered the children’s expressed preferences for England, their emotional and educational needs, the importance of keeping them together, the competing risks and the mother’s evidence of abstinence supported by hair strand testing. It identified a risk of emotional harm in the father’s care on the limited material available, without determining the allegations against him.
The interim arrangements provided that:
- both children would live with the mother and return to their school in State A;
- the mother could take them there on an undertaking to return them if ordered by the High Court;
- the father would have professionally supervised contact in State A on at least one weekend during the first half of term, on both Saturday and Sunday;
- supervised contact would take place in England during the half-term holiday on agreed dates; and
- professionally supervised video contact would occur before departure and after arrival.
The court treated continuity of schooling and the arrangements it described as the status quo as important. The children’s wishes were relevant but not determinative, particularly because the origins of X’s views remained disputed.
There is no inconsistency between overturning the final decision and making interim arrangements involving the same destination and primary carer. A final determination requires established facts and a full welfare assessment; an urgent interim decision must manage unresolved risks. The court expressly stated that its provisional assessment should carry no weight at the later determination, and the arrangements could be varied at the next interim hearing.
8. Likely Impact
- Maintaining the summary character of Hague proceedings: the decision discourages attempts to use return proceedings as an advance trial of broader parenting disputes, with resulting delay and expense.
- Scrutiny of earlier judgments: practitioners must identify what was actually decided, why it required decision and how the evidence was tested before treating an earlier statement as an established fact.
- Care in guardian assessments: failure to accept an allegation cannot fairly be treated as lack of insight merely because a previous judgment expressed an adverse impression.
- Integrated fact-finding: allegations of abuse, drinking and alienating behaviour require assessment together where they provide competing explanations for a child’s experience.
- Clear provisional language: interim risk assessments should be expressly distinguished from final findings so that protective decisions do not improperly determine the later trial.
The judgment remains carefully limited. It does not prohibit all reliance on findings from Convention proceedings, require a separate fact-finding hearing in every disputed case, or establish that children’s expressed wishes must prevail. Its concern is the proper factual and procedural foundation for the particular decision being made.
9. Complex Concepts Simplified
- Habitual residence
- The child’s factual centre of life, assessed in context. Here, the finding that it remained in England and Wales disposed of the Convention application.
- Summary proceedings
- A focused process designed to resolve specified issues promptly, rather than determine every aspect of the family dispute.
- De novo assessment
- Considering an issue afresh, without requiring a party to overturn an earlier impression treated as established.
- Burden and standard of proof
- The party making an allegation ordinarily must establish it as more likely than not. Strong judicial wording does not transfer that responsibility to the opposing party.
- Alienating behaviour
- Alleged conduct that damages a child’s relationship with another parent. A child’s resistance alone does not establish its cause; abuse, protective responses and other explanations must be examined.
- Interim risk assessment
- A provisional evaluation used to protect a child while disputed facts await determination. It is not a final finding that alleged misconduct occurred.
10. Conclusion
X & Y (Child Arrangements: Findings) reinforces a fundamental requirement of fair welfare adjudication: serious disputed allegations must be determined through the process appropriate to the decision being made. Unnecessary impressions from summary Hague proceedings cannot become established findings through repetition, professional reliance or a party’s failure to appeal them.
The decision also demonstrates that procedural fairness and immediate protection operate together. The court required a fresh determination of all substantive allegations while making cautious, expressly provisional arrangements to protect the children pending that determination.
