Defending International Child Abduction Proceedings: Grounds and Protection

By Dr. Mauricio Ejchel

Defending an international return application requires examination of the alleged wrongfulness of the removal, the Convention grounds for opposition and the child’s concrete protection needs. Domestic violence, material insecurity and isolation abroad may form part of that analysis, but do not justify premature conclusions about either caregiver’s conduct or the proceedings’ outcome.

This article focuses on substantive grounds of defence and safety assessment. Organising the response before the Central Authority and federal court, with its documentary chronology, is addressed in the companion article on procedure and evidence.

1. The purpose of return and the Convention’s requirements

The 1980 Hague Convention seeks to protect children from the harmful effects of wrongful removal or retention and secure respect for custody and access rights between Contracting States. Disruption of contact with relatives, classmates and teachers, and of ties established in the place of residence, forms part of the treaty’s protective rationale. Its objects, defined in Article 1, nevertheless do not remove the need to examine its application requirements and express exceptions. Decree No. 3.413/2000 promulgated the Convention in Brazil.

Civil characterisation of abduction depends on Article 3: there must be a breach of custody rights attributed under the law of the state of habitual residence immediately before removal or retention, actually exercised or which would have been exercised but for it. Those rights may arise by operation of law, a judicial or administrative decision, or an agreement having legal effect in that system; a prior sole-custody judgment is not necessarily required. Article 5 includes the right to determine residence. Lawful entry into Brazil or possession of travel documents does not, alone, resolve the issue.

The child’s habitual residence, the under-sixteen limit in Article 4 and the treaty’s operation between the states and at the relevant dates must also be checked, including Articles 35 and 38. Brazilian nationality, birth in Brazil and the parents’ nationalities do not replace habitual residence. Likewise, an initially authorised journey may become disputed through subsequent retention: the authorisation’s content and the moment when continued residence became contrary to custody rights must be identified individually.

2. Violence, isolation and access to justice abroad

Convention protection does not permit disregard of assaults against a child or caregiver, threats, psychological violence, emotional abandonment or neglect of care, unsafe housing or social isolation. Each circumstance requires its own account: who acted, during which period, who was affected, what consequences followed and what evidence can establish it. Legal relevance arises from that factual connection to the disputed return, rather than a presumption of suffering or safety associated with a caregiver’s sex or nationality.

Economic dependence, language barriers and difficulty obtaining legal assistance may restrict a person’s actual options abroad. That does not justify general assertions that judicial relocation permission would have been impossible, the other parent would never have consented, or every foreign system is financially inaccessible. The obstacles encountered, steps attempted and protection obtainable in the particular case must be identified. Article 25 provides access to legal aid and advice on its stated conditions, without guaranteeing assistance or a favourable outcome.

An adult’s departure and an international change in the child’s residence are distinct questions. Before travel, analysis should cover the scope of custody rights, existing authorisation and protection or permission routes available under applicable law. If return is already sought, the urgency of the circumstances experienced must be examined without treating travel motives as automatic proof of lawfulness or the absence of an earlier solution as waiver of a defence.

3. Article 13(a): exercise of custody, consent and subsequent acquiescence

Article 13, first paragraph, subparagraph (a), addresses non-exercise of custody at the relevant time, consent to removal or retention and subsequent acquiescence. Although related, these are different grounds. The defence must clarify whether it disputes earlier exercise, relies on prior permission or invokes subsequent conduct expressing acceptance of continued residence. A parent’s present opposition does not dispense with assessment of the facts and documents supporting each possibility.

Exercise of custody requires reconstruction of the care and decisions actually undertaken, in light of the rights recognised by the law of habitual residence. Absence of daily contact cannot be equated, without examination, with absence of rights; nor does maintenance payment alone answer the question. Article 3 itself includes exercise that would have occurred but for the abduction. Alleged abandonment must therefore be specified, distinguishing marital disagreement, physical absence and legally relevant non-exercise.

Consent requires examination of the authorisation’s purpose, duration, conditions and persons covered. Permission for a holiday or visit does not necessarily mean agreement to permanent residence in Brazil. Subsequent acquiescence requires assessment of the context of communications and behaviour; it does not follow automatically from an isolated message, negotiations or attempts to maintain contact with the child. Preserving complete records permits evaluation of their significance without excerpts that distort the statement’s meaning.

4. Article 13(b): grave risk and domestic violence

Article 13, first paragraph, subparagraph (b), concerns a grave risk that return would expose the child to physical or psychological harm or otherwise place the child in an intolerable situation. Analysis is prospective: past events inform examination of what may happen under the return conditions actually contemplated. Marital separation, parental conflict or better economic circumstances in Brazil do not, alone, establish the Convention ground. Nor may violence be dismissed merely because it targeted the other caregiver rather than the child directly.

The STF’s official communication of 27 August 2025, reproducing the holding in ADIs 4.245 and 7.686, recognises the Convention’s compatibility with the Constitution and its status above ordinary legislation. For Article 13(1)(b), the published holding requires interpretation consistent with the child’s best interests and a gender perspective, admitting the exception on objective, concrete indications of domestic violence even where the child is not the direct victim. This parameter excludes both a requirement of direct violence against the child and refusal based solely on a generic allegation.

The treaty does not make consideration of risk conditional on a prior criminal conviction of the alleged perpetrator. The defence must present relevant indications and explain their connection to the child’s integrity: exposure to violence, threats against the caregiver, impairment of care or other individual consequences. Service records, messages, protective decisions, medical documents, expert assessments and accounts from people with knowledge of the facts may assist, subject to reasoned evaluation and the opportunity to contest them. Allegation, document, technical conclusion and judicial decision are not interchangeable categories.

The inquiry must extend to protection available in the state of habitual residence. The HCCH Guide to Good Practice, Part VI, particularly paragraphs 43–47 and 57–60, directs attention to the adequacy, accessibility and effectiveness of measures, distinguishing them from mere promises. Formal availability of services or an order does not dispense with checking their usefulness against the alleged risk; previous breaches of protection may also matter. This is official interpretative guidance, which replaces neither Convention law nor Brazilian judicial examination.

5. The child’s objections and assessment of maturity

The second paragraph of Article 13 allows consideration of a child’s objections to return where the child has attained an age and degree of maturity making it appropriate to take account of those views. The Convention fixes no age at which children may freely choose their country of residence. Objection to return must be distinguished from preference for a parent, school or material circumstances, examining the content and formation of the views expressed.

The hearing must preserve the child’s freedom without requiring resolution of the adults’ conflict or repetition of a prepared account. CNJ Resolution No. 449/2022 provides for hearing the child and checking undue influence. Its reference to children over twelve in Article 12(III) neither makes age a binding choice nor replaces the Convention requirements of objection and maturity. The defence should justify participation and necessary safeguards rather than present a child’s statement as the decision on the application.

6. Social information and reconstruction of the family context

The final paragraph of Article 13 requires consideration of information about the child’s social background supplied by the Central Authority or another competent authority of the state of habitual residence. This preserves the relevance of the previous environment, care received, family ties and protection conditions. It neither makes an administrative report conclusive nor prevents the defence from providing material that explains or contradicts it.

A useful reconstruction connects each item to the ground invoked: care before removal to exercise of custody; authorisation and communications to consent; violence and protection history to grave risk; independently formed views to the child’s objections. Social information must not be reduced to an abstract comparison between families or countries, nor used to introduce settlement in Brazil outside Article 12’s proper framework.

7. The one-year period and Article 20’s limits

Article 12 relates the one-year period to wrongful removal or retention and commencement of proceedings before the competent judicial or administrative authority of the state where the child is located. Return remains prescribed after that period, subject to proof that the child is now settled in the new environment. Mere passage of time establishes no right to remain. Before the Convention threshold, adaptation to Brazil is not an independent settlement ground for refusing return.

Articles 12(V) and 14, § 3, of CNJ Resolution No. 449/2022 contain specific references to receipt of the cooperation request by the Brazilian state and Central Authority, alongside direct judicial filing. These domestic provisions must be identified separately from the treaty text; its trigger must not be replaced, without reasons, by mere administrative receipt, nor distinct acts declared equivalent. The chronology and classification of the route used must form part of the legal analysis.

Article 20 permits refusal where return would not be allowed by the requested state’s fundamental principles relating to protection of human rights and fundamental freedoms. Invoking it requires specification of the alleged incompatibility and its concrete elements. It authorises neither broad reconsideration of custody convenience nor replacement of Convention criteria with national preference or an abstract assertion about best interests detached from the case.

8. Protection in Brazil, jurisdiction and preventive advice

The Central Authority performs cooperation and administrative preparation functions; in Brazil, MJSP Order No. 688/2024 assigns them to the DRCI within the ACAF framework. Its activity is neither custody adjudication nor a final judicial return decision. Convention return proceedings are heard by the federal courts; Resolution No. 449/2022 governs the Union’s participation and notice to the Federal Public Prosecutor’s Office. The AGU, MPF, Central Authority and party’s lawyer perform distinct roles.

Where current danger exists, the defence should seek appropriate protection before the competent authority and explain its relationship to the Convention dispute. Article 18 of Resolution No. 449/2022 addresses interim relief, including measures against further wrongful removal and protection against risks to the child. None follows automatically from filing proceedings: necessity, scope and basis require examination in the case. A protective order and a return decision have distinct objects, although material from one may be relevant to the other.

Nor does a return action finally determine custody. Articles 16, 17 and 19 distinguish these matters and delimit the effects of custody decisions in the requested state. Before travel or upon receiving a return demand, legal advice should clarify rights, authorisations, safety, evidence and concrete procedural options. The defence seeks a reasoned decision on Convention requirements and obstacles while preserving the child’s protection, without promising residence in Brazil or a favourable result.

Frequently asked questions

Does the child’s Brazilian nationality prevent return?

It is not an obstacle by itself. Articles 3 and 4 connect analysis to previous habitual residence and custody rights; treaty operation and opposition grounds must also be examined. Nationality and habitual residence are not equivalent requirements.

Must there be a prior sole-custody judgment for abduction to occur?

Not necessarily. Article 3 permits custody rights arising by operation of law, a judicial or administrative decision, or a legally effective agreement. Their scope, including decisions about residence, must be checked under the relevant legal system.

Can domestic violence be considered only after a criminal conviction?

Article 13(1)(b) imposes no such condition. The holding reproduced in the STF’s official communication of 27 August 2025 refers to objective, concrete indications of domestic violence, even without direct assault on the child. Risk and its connection to return remain subject to individual assessment.

Does a child over twelve decide whether to return?

There is no unrestricted choice based on age. Article 13 requires objections to return and sufficient age and maturity to consider the views expressed. The hearing must assess their content and freedom without making the child the dispute’s arbiter.

Does refusal of return establish custody in Brazil?

A Convention return decision does not, by itself, determine custody merits, under Article 19. Parental issues require their own analysis of jurisdiction, applicable law and relevant decisions.
