Hague Convention representation / Defending a return petition

For responding parents

Defending a Hague Convention petition.

A return petition can place a parent on an exceptionally compressed schedule. The response must test every element of the petitioner’s claim, identify any Convention defense, and develop admissible evidence without losing sight of what the proceeding actually decides.

Return is not custody

A Hague proceeding ordinarily decides whether the child should be returned to the country of habitual residence—not which parent should receive permanent custody.

The defenses are limited

General best-interest arguments are not enough. A successful defense must fit the Convention and satisfy ICARA’s applicable burden of proof with evidence the court can consider promptly.

The legal framework

Potential grounds for opposing return.

Defense begins before the exceptions. The petitioner must prove wrongful removal or retention by a preponderance of the evidence. That permits challenges to habitual residence, custody rights, breach, exercise of rights, treaty applicability, and timing. If the petitioner meets that burden, the respondent may assert one or more recognized defenses.

Article 13(b) · Clear and convincing evidence

Grave risk of harm

Whether return would expose the child to a grave risk of physical or psychological harm or otherwise place the child in an intolerable situation. The proof may require carefully framed testimony, records, and qualified expert evidence.

Article 13(a) · Preponderance of the evidence

Consent or acquiescence

Whether the petitioner agreed to the removal or retention beforehand, or later accepted it. The timing, wording, circumstances, and subsequent conduct surrounding communications can be decisive.

Article 12 · Preponderance of the evidence

Child now well settled

When proceedings began more than one year after the wrongful removal or retention, whether the child is now settled in the new environment. School, home, community, immigration, and family evidence may matter.

Article 13 · Preponderance of the evidence

Mature child’s objection

Whether a child of sufficient age and maturity genuinely objects to return. An objection is distinct from a preference, and courts consider the child’s maturity and the independence of the views expressed.

Petitioner’s prima facie case

No wrongful removal or retention

Return is not required if the petitioner cannot prove the child’s habitual residence, a breach of rights of custody under the governing law, or the actual or would-be exercise of those rights.

Article 20 · Clear and convincing evidence

Fundamental principles

The narrow question whether return would be prohibited by fundamental principles of the requested country relating to the protection of human rights and fundamental freedoms.

The first response

Build the defense on an expedited clock.

Courts may set early hearings and compressed deadlines for discovery, experts, exhibits, translations, and briefing. The initial response should protect the client’s position while rapidly defining the factual and legal issues that actually require proof.

01

Control the calendar

Identify service, response and hearing deadlines; existing orders; travel restrictions; the child’s location; and any request for provisional relief.

02

Test the return claim

Examine habitual residence, the law governing custody rights, whether those rights were breached and exercised, the date of retention, and Convention applicability.

03

Define each defense

Match the facts to the precise treaty standard and burden of proof. Avoid turning the case into a generalized custody or best-interest dispute.

04

Prepare the hearing record

Develop witnesses, experts, foreign records, translations, digital evidence, demonstratives, and legal briefing with possible appellate review in mind.

Evidence development

Preserve the complete story early.

Communications and chronologyComplete message threads, emails, travel plans, return discussions, objections, consent, and post-move conduct.
Child-focused recordsSchool, medical, mental-health, child-protection, police, housing, immigration, and community records relevant to the asserted issues.
Foreign law and proceedingsCustody orders, statutes, filings, investigations, agency records, and reliable translations from the country of habitual residence.
Expert evidenceWhen appropriate, a properly limited clinical or forensic inquiry tied to the governing legal standard—not a general custody evaluation.
Authentication and presentationOriginal files, metadata, qualified witnesses, evidentiary foundations, translations, and a practical plan for the expedited hearing.

Prompt defense assessment

If you were served—or expect a petition—bring the papers and the timeline.

For the first conversation, have the petition, summons, orders, hearing dates, countries involved, removal or retention dates, the child’s current location, and the most important communications available. Do not send highly sensitive documents until secure delivery arrangements are confirmed.
