Child Custody in Spain for US Military Families: What Can Happen and How We Work

Divorce and custody near Naval Station Rota, explained in plain English: the situations we see most often, and what we do in each one.

Many custody disputes at Rota begin the same way. A marriage that held together through deployments and moves comes apart while the family happens to be in Spain. One parent has a lawyer and a plan. The other learns about it from a phone call, a draft agreement slipped across the kitchen table, or a court document in a language they do not read.

If that is where you are, you need to know two things before anything else. First, a Spanish court will very probably decide where your children live, and it will apply Spanish law. Second, Spanish law does not start from the idea that children belong with one parent. Joint custody is treated as the normal arrangement whenever it serves the children. What happens next depends on how your case is prepared.

This article sets out the situations we see most often among American service members and their families, and how our firm handles each one.

Why the Spanish courts decide

For children who live in Spain, custody is decided in Spain. Under European Union law (Regulation (EU) 2019/1111, Article 7), the courts of a Member State have jurisdiction over parental responsibility for a child who is habitually resident in that State when the case is filed. Your nationality, your spouse’s nationality and the fact that you were posted here by the Navy do not change that rule. What counts is where the children’s lives are: their home, their school, their routine.

The other side of the Atlantic generally points the same way. Most US states follow the Uniform Child Custody Jurisdiction and Enforcement Act, which treats a foreign country as if it were a US state when deciding which court is the right one. For children who have lived in Spain for the last six months or more, Spain is usually their «home state».

Under Spanish law, a child’s habitual residence can only be changed with the consent of both parents or the authorization of a court (Article 154 of the Civil Code). Neither parent can settle the question by simply moving.

How Spanish courts look at joint custody

In 2013 the Spanish Supreme Court established that joint custody «is not an exceptional measure» and «should be considered normal and even desirable», because it allows children to keep a real relationship with both parents, even in a crisis, whenever that is possible (Supreme Court judgment 257/2013, of 29 April). Since then the Court has repeated that the deciding factor is always the best interests of the children.

The same judgment lists what judges weigh in practice:

• how each parent has cared for the children until now, and their personal abilities;
• the wishes of children who are mature enough to express them;
• the number of children;
• whether each parent has met their responsibilities towards the children;
• mutual respect between the parents;
• the reports required by law, such as the court’s psychosocial assessment;
• anything else that gives the children a stable and suitable life.

For a service member, the honest questions are practical ones. Can you actually look after the children on your weeks? Who covers them when you have duty? What happens if you are sent to sea? A judge will not award joint custody on good intentions. A judge will award it on a workable plan. The parent who brings a realistic schedule, built around the duty roster, the school calendar and the distance between the two homes, is the parent who is taken seriously.

What can happen: the situations we see most often

1. Your spouse has already filed, and you have not been served

This is more common than people think. A case can be filed in Spain weeks or months before the other parent is formally notified. In the meantime, negotiations go on, and the parent who filed may push for a signed agreement before the formal deadlines start.

What matters:

• The clock has not started yet. In Spanish family proceedings, the respondent has twenty working days from formal service to file an answer. Until you are served, that period does not run.
• Do not wait for it to start. We can enter an appearance in the proceedings on your behalf, obtain the full court file and begin preparing your answer straight away. Twenty working days pass quickly when evidence must be gathered, translated and organized.
• Your answer can do more than defend. The court must decide on custody, contact and child support in any event, so your answer is not limited to opposing your spouse’s request. It can set out your own proposal, joint custody with a parenting schedule and the related measures, backed by evidence. If you only oppose, the judge has one detailed plan in front of them, and it is not yours.
• Do not sign anything you have not reviewed with your own lawyer, however reasonable it looks. A signed agreement approved by a court is very difficult to undo.

2. You want to start the case yourself

Filing first is not a race. It is a decision about who sets out the facts and the proposed arrangement in the first document the judge reads. If your marriage is over and the arrangement for the children is not settled, it is often better to file a well-prepared claim than to wait for one.

Before a case is filed, either parent can also ask the court for urgent temporary measures, covering who the children live with, the visiting schedule, support and use of the family home, while the main case goes ahead.

3. The other parent wants to take the children back to the United States

This is the scenario that worries military families most, and with good reason.

Moving the children to another country is a change of their habitual residence. Under Spanish law it requires your written consent or a court order. If one parent takes the children abroad, or keeps them there after a holiday, without that consent or order, it is a wrongful removal under the 1980 Hague Convention on International Child Abduction. Spain and the United States are both parties to that Convention, and the remedy is an order for the child’s return.

When there is a real risk, Spanish judges can act before anything happens. Article 158 of the Civil Code allows a court to prohibit a child from leaving Spain without prior court authorization, to prohibit the issue of a passport or withdraw one already issued, and to require court approval for any change of the child’s address.

Americans should also know that a US passport for a child under sixteen normally requires the consent of both parents, unless one of them has a court order granting sole authority. Both rules matter, because Spanish and US passports are issued by different countries.

If the request to relocate is made openly, it is decided openly: the court weighs the reasons for the move, the effect on the children and the relationship with the parent who stays. Relocation is not automatically granted or refused.

4. You receive orders before you retire

A Permanent Change of Station can turn a working arrangement into a dispute overnight. If you leave Spain and the children stay, the custody arrangement will have to be modified. Spanish law allows the measures to be changed when there has been a substantial change of circumstances.

The best time to deal with this is before the orders arrive. A good parenting plan can include a clause for long-distance contact, holiday periods, video calls and who pays for travel. The Spanish Supreme Court has set out how those travel costs are shared when parents live far apart; we have written about it in Spanish, in our article on who pays for travel under a visitation schedule.

5. You plan to retire and stay in Spain

A parent who intends to stay in Spain for the rest of the children’s childhood is offering exactly what courts look for: stability and continuity. That intention has to be shown, not just stated. Evidence of housing, schooling, retirement date and plans for life after the Navy all count.

Bear in mind that your legal status in Spain will change when you leave active duty and the status that comes with the Spain–US defense agreement. Your residence after retirement should be planned well in advance, so that it supports your custody case rather than weakening it.

6. Child support and money across the Atlantic

A Spanish court that decides custody also sets child support. Enforcing support between Spain and the United States is easier than it used to be: both are bound by the 2007 Hague Convention on the International Recovery of Child Support, and a Spanish order can be registered and enforced in a US state.

Military retirement pay is a separate subject, governed by US federal law, and a Spanish decree is not automatically accepted for direct payment. We explain it on our page for English-speaking families.

7. You were already divorced in the United States

A US decree does not lose its value because the family is now in Spain, but it does not take effect here automatically either. To be enforced in Spain it must first be recognized by a Spanish court. And if the children now live in Spain, any request to change the custody arrangement will normally be heard by the Spanish courts, not by the court that granted the original decree.

How we work

Every family is different, but our method is the same.

1. A first meeting, in English. We listen to the whole story, review every document you have and tell you plainly where you stand. The first feasibility assessment is at no cost and without obligation.

2. A clean change of lawyer, if you already have one. Changing lawyers in the middle of a case is your right. In Spain it follows a formal courtesy procedure between lawyers, which we handle for you. We also prepare the power of attorney needed to act in court, and we make sure the new team has the complete file from day one.

3. Full access to the court file. We do not work from summaries. We obtain everything the court has, including the claim, the evidence and any temporary measures, and we read it before we advise you.

4. A strategy built on evidence. A full answer with your own proposal for the children; urgent temporary measures if needed; a detailed parenting plan built around your duty schedule; documents from your command on your schedule and expected service; school and housing records; witnesses; and preparation for the court’s psychosocial assessment and for the hearing of the children where it applies.

5. Protection where there is a risk. If there is a real danger that the children may be taken out of Spain, we ask the court for protective measures without delay.

6. Coordination with the United States. Where a case touches US law, such as military retirement pay, a state court order or recognition of a Spanish decree, we work with the base Legal Assistance Office and with US counsel. Documents are prepared with sworn translations and the apostille, so that they can be used on both sides.

7. Firm, but never reckless. We are firm in court. We also know that Spanish judges notice which parent is reasonable, which parent supports the children’s relationship with the other one, and which parent turns everything into a battle. We fight for joint custody without giving the other side the argument that you are the problem. If a fair agreement is possible, we will tell you, and we will negotiate it from a position of strength.

8. A fixed written quote. You will know the cost of each stage before it begins.

A final word

The parent who prepares early, documents well and stays reasonable is the parent who gets heard. Custody in Spain is not won by volume. It is won by showing a court, with evidence, that the children will be better off with both parents in their lives, and that you have a plan to make it work.
