International Child Return in Argentina: When Does the Hague Convention Apply?

Short answer

The 1980 Hague Convention may provide a return remedy when a child under sixteen was habitually resident in a State bound by the Convention with Argentina immediately before a removal or retention, and the move breached rights of custody that were being exercised or would have been exercised. Each element must be proved. The Convention does not decide permanent custody, and its limited refusal grounds must be assessed on the evidence.

What the Hague return procedure is designed to do

The Convention seeks the prompt return of a child to the State of habitual residence after a wrongful removal or retention. It restores the forum in which custody issues should ordinarily be decided; it does not award permanent custody to either parent. A return order is therefore different from a custody judgment, and a refusal to return is not automatically a final custody determination.

The four questions that usually determine whether the Convention applies

The initial review should establish whether the child was under sixteen; where the child was habitually resident immediately before the disputed event; whether the removal or retention breached rights of custody under the law of that State; and whether those rights were actually exercised or would have been exercised but for the event. Rights of custody may arise by operation of law, a judicial or administrative decision, or a legally effective agreement; a prior custody order is not always indispensable.

Habitual residence is not the same as citizenship

A passport, nationality or place of birth does not by itself establish habitual residence. The analysis is factual and legally contextual. Depending on the case, evidence may include the child’s housing, school, healthcare, family routines, activities, duration and stability of residence, and the parents’ arrangements. The relevant point in time is immediately before the alleged wrongful removal or retention.

A lawful trip can become a wrongful retention

A trip authorised for a holiday or limited stay is not wrongful merely because one parent later regrets it. The continued stay becomes legally relevant when it breaches rights of custody under the law of the child’s habitual residence. The agreed return date, travel authorisation, messages and conduct of both parents may help identify whether and when a wrongful retention began.

Delay, the one-year period and settlement

If proceedings begin less than one year after the wrongful removal or retention, Article 12 directs prompt return when the Convention requirements are met. After one year, return may still be ordered, but the requested person may attempt to prove that the child is now settled in the new environment. One year is therefore not a licence to retain a child and not an automatic bar to return; it changes part of the analysis.

The grounds for refusing return are limited

Possible grounds include lack of actual exercise of custody rights, consent or later acquiescence, a grave risk of physical or psychological harm or an intolerable situation, and a sufficiently mature child’s genuine objection to return. Article 20 contains an additional narrow human-rights ground. Argentine Supreme Court doctrine treats Convention exceptions restrictively: ordinary disruption, a preference for one parent or a general custody argument is not enough by itself.

Treaty coverage must be checked for the two States

Argentina has been bound by the 1980 Convention since 1991, but the Convention must also operate between Argentina and the other State. For some States that joined by accession, bilateral acceptance rules matter. When both States are parties to the Inter-American Return Convention as well as the 1980 Hague Convention, Article 34 of the Inter-American Convention gives the Inter-American instrument priority unless the States have agreed bilaterally to prioritise the Hague Convention. Outside a treaty’s scope, Argentine Civil and Commercial Code Article 2642 may also be relevant.
