Moving to Spain with a child in shared custody: consent, relocation and the Hague Convention

Most of the families we help are moving together. A minority are not. A parent has separated or divorced, has a job offer or a remote-work permit or simply wants to start again on the Costa del Sol, and the child is coming too. The immigration file for that child is usually the easy part — a dependent on the parent’s application, or a family reunification later.

The hard part is invisible on the immigration file. Moving a child across a border is not an immigration decision at all. It is a family-law decision about where a child lives, and in most separated families it does not belong to one parent alone. Getting the visa right and this wrong is the single most expensive sequence of events we see in family relocations, because the remedy is fast, blunt and international: the child goes back.

This page sets out what the law treats as a wrongful removal, what a return application looks like once the child is in Spain, what consent to obtain before you fly, and the smaller Spanish checkpoints — the padrón, the child’s residence card, the school — that quietly ask the same question again after you arrive.

“When a parent calls me from Málaga airport, the visa is almost never the problem. The problem is a sentence in a divorce order from three years ago that nobody re-read. That sentence is enforceable across the Atlantic in a matter of weeks, and by then the child has already unpacked. Read the order before you book the flights, not after.”

The short answer

If you share parental responsibility for a child — and in most separated families you do, even where the child lives mainly with one parent — you need either the written consent of the other parent or a court order permitting relocation before you take that child to live in Spain. Not afterwards. Not implied by silence. Not replaced by an approved visa.

If you move without one, the other parent can file a return application under the 1980 Hague Convention on the Civil Aspects of International Child Abduction. Spain and the United States are both parties, as are the United Kingdom, Canada, Australia, Ireland and every EU state, so the application runs. In Spain it is heard under a fast-track procedure designed to conclude within six weeks, and it is not a re-run of the custody dispute: the court asks whether the removal was wrongful, not who is the better parent.

The visa is one permission; removal is another

Consulates do not adjudicate custody. When a child is included as a dependent on a non-lucrative visa, a digital nomad application or a work permit, the file is checked for the things immigration law cares about: the relationship, the means, the accommodation, the insurance, the criminal record certificates. Nothing in that list is a question about the other parent’s agreement, and a visa officer who granted the application has expressed no view whatsoever on whether the child may lawfully leave.

Some consulates do ask for a notarised authorisation from a non-travelling parent, and that is useful when it happens. But it is an administrative convenience, not a legal safe harbour, and its absence proves nothing. We have seen applications approved on files where the other parent’s name appeared nowhere at all. The approval was correct as an immigration decision. It was also completely irrelevant to the family-law question underneath it.

The practical failure mode is psychological rather than legal. A parent spends four months assembling apostilled documents, pays the fees, waits, and receives a formal government decision saying yes. It is very hard, after that, to hear that a second and quite separate yes was needed. But the two decisions come from different systems and neither one substitutes for the other.

What counts as a wrongful removal

The 1980 Hague Convention uses two ideas that do most of the work: habitual residence and rights of custody.

Habitual residence is where the child actually lived their settled life before the move — the school, the doctor, the family, the routine. It is not a nationality and not a legal domicile. In the United States the Supreme Court settled the test in Monasky v. Taglieri in February 2020: habitual residence depends on the totality of the circumstances of the particular case, a fact-driven inquiry using common sense, rather than any categorical rule such as a requirement that the parents actually agreed on where the child would live. For very young children, the intentions and circumstances of the caregiving parents carry particular weight.

Rights of custody is broader than the phrase suggests to most parents. It includes the right to determine the child’s place of residence, and that right is frequently held jointly even where one parent has day-to-day care and the other has contact every other weekend. It can also arise from a clause in an order or agreement prohibiting removal from the jurisdiction without written consent or leave of the court — a clause that sits in a great many separation agreements and is read by a great many parents as boilerplate.

A removal is wrongful where a child is taken from the country of habitual residence in breach of rights of custody that were actually being exercised. A retention is wrongful in the same way where the child travelled lawfully — a summer visit to grandparents in Marbella, agreed in writing — and simply was not sent back. The retention cases are the ones parents most often do not see coming, because the departure itself was consensual and the breach only crystallises on the day the return flight is missed.

What a return application looks like in Spain

When a child has been brought to Spain, the left-behind parent applies through the Central Authority in their own country, which transmits the file to the Spanish Central Authority — the Subdirectorate General for International Legal Cooperation at the Ministry of Justice. That office checks the papers, and where the child has been brought into Spain it forwards the application to the public prosecutor in the province where the child is located. Where the address is unknown, Interpol can be asked to locate the child.

The case is then heard under articles 778 quater to 778 sexies of the Civil Procedure Act — the dedicated procedure Spain enacted so that Convention cases would not be swallowed by ordinary family timetables. It is built to conclude within six weeks, hearings are compressed, and where the child’s location is known a first-instance decision can come considerably faster than that.

Three things surprise parents about this hearing:

• It is not a custody hearing. The court is deciding a narrow question about where the case should be heard, in effect, by deciding whether the child returns to the country that was hearing it. Arguments about which parent is more suitable belong to the court of the habitual residence.
• The defences are narrow. Consent or acquiescence, a grave risk of physical or psychological harm, the objection of a sufficiently mature child, and the settlement of a child where more than a year has passed. They exist, they occasionally succeed, and they are read restrictively. “The child is happier here” is not one of them.
• Speed is the point. The whole design of the Convention is to undo the removal before the new situation becomes the child’s reality. That is why a family that has been in Spain for two months has far less to argue about than the passage of time might suggest.

The mirror image is true too. A parent whose child has been taken from Spain to the United States applies through the Spanish Central Authority, which translates and transmits the file to the receiving country. Either way, the first practical step is the same: get the application in early, because delay is the one thing that starts to work against the applicant.

The criminal side: article 225 bis

The civil return proceeding is not the only exposure. Article 225 bis of the Spanish Penal Code makes it an offence for a parent to remove a minor child from their habitual residence without the consent of the other parent or of the person or institution holding custody. The penalty is two to four years in prison together with disqualification from the exercise of parental authority for four to ten years, and it is imposed in its upper half where the child has been taken outside Spain or where a condition is attached to the child’s return.

There is a graduated way down. Where the child is restored within fifteen days of the complaint, the range drops to six months to two years. The article also reaches the child’s grandparents and relatives of the removing parent up to the second degree who take part in the conduct — a detail worth knowing before extended family is asked to help with a plan of this kind.

For a family moving into Spain, the immediate criminal risk more often sits in the country the child left. But the Spanish article matters in two directions: it applies to a child whose habitual residence had already become Spain and who is then taken away, and it explains why Spanish prosecutors are involved in incoming Convention cases at all.

What to settle before you fly

There are only two clean routes, and both of them exist entirely in the country the child is leaving.

Route one: written consent from the other parent

The strongest version is not a text message and not an email saying “fine, go”. It is a document that names the child, states the destination country and address, states the intended date and that the move is permanent, sets out the contact arrangements that will replace the current ones, and is signed and notarised. Where the existing arrangements come from a court order, the safer course is usually to have the agreed variation entered as a consent order rather than left as a private agreement, because a private agreement can be disavowed and an order cannot.

Build the contact schedule into the document in real terms — flights, who pays, video-call rhythm, how holidays split, which country the child spends the long summer in. Vagueness here is what turns a cooperative agreement into litigation eighteen months later, and a well-drafted schedule is also the most persuasive material a relocating parent has if the matter ever does reach a court.

Route two: a relocation order from the court with jurisdiction

Where the other parent will not agree, permission has to come from the court that currently deals with the child — typically in the country of habitual residence, before the move. Terminology varies by country: relocation, removal from the jurisdiction, move-away. What does not vary is that the application is made where the child is now, and that filing it after arriving in Spain is close to the worst available order of operations. It converts a lawful request into a fait accompli, which is exactly the posture the Convention was written to reverse.

These are family-law proceedings in the child’s home country, so the lawyer who runs them is a family lawyer admitted there. Our role in that phase is the Spanish half of the picture: what the child’s status here will be, what the residence file requires, what a Spanish court would later look at. We work alongside the home-country lawyer rather than instead of them.

Two American housekeeping items

For US families there are two administrative details worth knowing early. The first is the passport rule: a US passport for a child under sixteen requires the consent of both parents, and where one cannot appear, form DS-3053 provides a notarised statement of consent. The second is the Children’s Passport Issuance Alert Program, a free State Department service that lets a parent be notified when a passport application is submitted for their child, run by the Office of Children’s Issues. Both cut both ways: they are prevention tools for a worried parent, and they are also the reason a unilateral plan involving a new passport tends not to stay quiet. If a US passport renewal is part of your move, our note on renewing a US passport from Spain covers the mechanics.

The Spanish checkpoints after you arrive

Spain does not run a border check on custody, but it asks the same question repeatedly through ordinary administration, and parents who arrived without consent tend to meet it at the padrón desk first.

The padrón. Registering a minor at an address with only one parent is governed by the joint instruction of the Instituto Nacional de Estadística and the Directorate-General for Local Cooperation of 17 February 2020, amended in February 2023. The instruction distinguishes the situations expressly: where both parents consent, the consent can be recorded on the registration sheet or attached as a written authorisation; where there is a judicial authorisation, that is produced instead; and where neither exists, registration is still possible in defined circumstances against a signed declaración responsable about the custody situation, using the official models annexed to the instruction. That declaration is a formal statement, not a formality — it is signed under the registrant’s responsibility, and it creates a dated record of what the moving parent asserted about custody. Our note on the padrón and the health card covers the ordinary process.

The child’s residence card. The minor’s own authorisation as the child of a legal resident is an immigration file, but it is signed for by whoever exercises parental authority, and a residence card is precisely a decision about where a child lives.

School enrolment. Under Spanish law the choice of school is a decision of parental authority, not of day-to-day care, and centres routinely ask for both signatures or for the judicial resolution that dispenses with one. Where the parents disagree, article 156 of the Civil Code sends the question to a judge, who hears both parents and hears the child where the child has sufficient maturity and in any event from the age of twelve, and then attributes the decision to one parent — for a fixed period that cannot exceed two years. If you are choosing between systems, our comparison of international schools in Spain is the practical companion to this.

None of these checkpoints will stop a determined parent on their own. Their real significance is evidential: each one generates a dated Spanish record of what was asserted about custody, and those records are read later, in a courtroom, by someone with the original order in front of them.

The 1996 Convention gap between Spain and the US

There is a structural gap in the US–Spain relationship that European families do not face. Within the EU, cross-border parental responsibility is knitted together by EU rules and by the 1996 Hague Child Protection Convention, which handles jurisdiction, applicable law and the recognition of protective measures — the framework that makes a custody order from one member state travel to another. Spain is a party. The United States signed the 1996 Convention on 10 October 2010 and has still not ratified it, and that remains the position in 2026.

The consequence is that only the 1980 Convention operates fully between the two countries. The 1980 Convention is a return remedy: it undoes wrongful removals. It does not make an American custody order automatically effective in Spain, nor a Spanish one automatically effective in the United States. Recognising a foreign order in Spain generally means an exequátur proceeding under Law 29/2015 on international legal cooperation in civil matters, which takes time and costs money and is a poor substitute for having dealt with the question in advance.

When jurisdiction moves to Spain — and why that cuts both ways

Habitual residence is not frozen. Once a child has genuinely settled in Spain — school, doctor, friendships, routine, time — Spain becomes the country whose courts deal with the child’s life, and future disputes about care and contact are argued here rather than in the country of departure.

Parents sometimes hear that and read it as a clock to run down. It is a bad reading, for two reasons. Time acquired through a wrongful removal is the weakest kind: the settlement defence is narrow, it generally comes into play only after more than a year has passed, and the removal itself colours everything a court later hears about that parent’s judgement. And the shift is symmetrical — the parent who moved lawfully to Spain becomes, in time, the parent whose child is habitually resident here, with the same protections against a unilateral move in the other direction.

Handled properly, that is the reassuring part of the story. A relocation done with consent or with an order produces a child who is settled in Spain, a Spanish court that will deal with any future dispute, and a contact schedule that both parents have already signed. Handled badly, it produces a six-week hearing in Málaga and a flight home.
