Travel, schools and registration
When a family has an international life (expatriation, dual nationality, work with frequent transfers or parents living in different countries), custody is not only decided by an agreement or a court ruling.
It comes down to routine decisions: school enrollment, a summer trip, a change of address, a health card, a "temporary" address that gets extended.
If the relationship ever becomes strained, those decisions become evidence . And in a cross-border matter, evidence determines which country decides.
Why habitual residence matters in international custody
In custody disputes with an international component , the decisive factor is usually where the child's life is : their effective, stable and recognizable center.
- In the EU (except Denmark), the legal compass of competition (who has jurisdiction over the case) and the recognition of decisions is determined by the Regulation (EU) 2019/1111 (Brussels II ter), applicable to proceedings initiated from the August 1th, 2022, and which also coordinates the response to international child abduction among Member States.
- Outside the EU (or in EU–third state relations), the map is completed by two key Hague treaties:
- El 1980 Convention (return in case of unlawful transfer or retention).
- El 1996 Convention (jurisdiction and protection measures based, as a rule, on the child's habitual residence).
If the child is integrated into a country (school, routine, doctor, home, activities, relationships), that country will have increasingly more arguments to be the center of gravity of the case.
International travel
In custody, the journey is legally delicate for two reasons.
- Traveling with a minor, in terms of parental authority, affects documentation, departures from the country, extended itineraries, or repeated stays. In Spain, parental authority is exercised as a rule jointly by both parents (or by one with the express or tacit consent of the other). If there is disagreement, either parent may appeal to the judicial authority to assign the power to decide on that specific matter.
- Documentation creates control. For the issuance of a passport for a minor, the following is required: express consent of those who have been assigned the exercise of parental authority or guardianship, and if that consent is lacking, the way is through judicial authorization.
Herein lies the blind spot: the parent who organizes the trips, keeps the passport and makes decisions on the fly can, without intending to escalate the conflict, leave the other in a fragile position.
And if the relationship worsens, that fragility translates into containment measures.
In fact, the Civil Code provides specific measures to prevent the abduction of minors: prohibition of leaving the territory, prohibition or withdrawal of passport and, especially relevant in mobile families, subjection to judicial authorization of any change of address of the minor.
It is intended to remind us that, in international custody, a border is not just a geographical line; it is a change of evidentiary scenario and, sometimes, of jurisdiction.
Change of school
Enrolling a child in a school in a country (and sustaining that schooling continuously) builds a very powerful narrative : weekly routine, language, assessments, teachers, extracurricular activities, friendships, social integration.
Therefore, when a family is separated or in the process of breaking up, changing schools should not be treated as a formality, but as a strategic decision; it can influence the child's perception of stability and the debate on where future parental responsibility measures should be resolved, especially under European schemes and the 1996 Convention, which revolve around habitual residence.
Registration and procedures
Registering your address is often perceived as an administrative formality.
But in international custody it has two practical effects: it helps to organize daily life (municipal services, schooling, etc.) and, if there is a conflict, it becomes a documentary indication of residence.
In Spain, there is also a detail that many families are unaware of: in the case of registration or change of address of a minor with both parents, the registration form or form signed by both is required.
And, if you live in several municipalities, the general rule is to register in the municipality where you live for the longest period of time during the year.
In international contexts, this type of administrative criterion can intersect with the legal debate about where the child's life actually is.
The risk is not registering. The risk is registering (or changing the register) as if it were irrelevant, without coordinating it with a cross-border custody plan.

How to decide: a planning approach for international profiles
A three-layered approach works well:
1) Documented and repeatable agreements. For travel, school, and home, what protects is a clear pattern: written authorization, basic conditions (dates, country, address, contact information), and a stable criterion for future situations.
2) A mobility protocol. Families with international lives need rules: how much notice is required for long trips, what constitutes a move, how a school change is decided, what happens if there is a job offer in another country, and how the child's documentation is managed. International custody arrangements break down more often due to improvisation than bad faith.
3) The Civil Code allows recourse to the judicial authority in cases of significant disagreement regarding parental rights, so that the power to decide on the matter may be assigned. And, if there is a risk, specific measures exist to prevent children from leaving the property, changing their address, or having passport issues.
Conclusion: In international custody, the everyday determines the extraordinary
Traveling, choosing a school, or registering your child may seem like managing your life.
In a cross-border scenario, it is also risk management.
The key is not to live in fear, but with a method; to understand that habitual residence is built with facts, that the EU and the Hague Conventions organize the "who decides" around that reality, and that Spanish law offers tools to prevent unilateral decisions from generating irreversible scenarios.
FAQs. Frequently asked questions
Not on its own. Registration is an indication, but in international custody cases, the reality of the child's life carries particular weight.
The issuance of a passport for a minor requires the express consent of those exercising parental authority or guardianship; if this is lacking, it must be replaced with judicial authorization.
If there is joint parental authority and there is no agreement, the correct way is to resolve the disagreement: the Civil Code provides to go to the judicial authority to assign the power to decide on that specific matter.
The Civil Code includes measures to prevent abduction: prohibition of leaving the country, passport requirements, and the need for judicial authorization for any changes of address for the minor. At the international level, the 1980 Convention establishes the right to return in cases of wrongful removal or retention (generally applicable up to the age of 16).
In the EU, the central framework is Regulation (EU) 2019/1111 (Brussels II ter), applicable to proceedings initiated from 1 August 2022, and coordinated with the 1980 Hague Convention on Abduction between Member States.
