Family Law in Spain for Expats — Divorce, Custody, Marriage
and Cross-Border Family Matters

Family law is rarely why anyone moves to Spain, and it is almost never what anyone plans to spend time on. But when a marriage breaks down, when a custody arrangement has to be rewritten because one parent wants to move, when a foreign divorce needs to be recognised here, or when a couple wants to marry in Spain without losing the protections of their home-country prenup — it matters enormously. Spanish family law runs on its own rules, its own courts, its own vocabulary, and its own relationship between civil law and EU regulation. Getting it right usually costs less than getting it wrong. Getting it wrong can change where your children live, how much you pay each month, and which country’s law governs the assets you spent a lifetime building.

This is the hub page for every family-law service we provide at Platinum Legal Spain. We’ve written it for anyone in the English-speaking expat community who needs clarity on how Spanish family law actually works, where the cross-border traps are, and what the full range of options looks like. Whether you’re a British couple in Málaga agreeing an amicable divorce, an American remote worker dealing with child maintenance across two jurisdictions, an Irish family with a holiday home at the centre of a separation, or a newly engaged couple signing a prenup before a wedding in Valencia, this is the right place to start.

Divorce and separation in Spain — the two paths

Spanish law offers two routes through a marriage ending: divorce by mutual agreement (divorcio de mutuo acuerdo) and contested divorce (divorcio contencioso). The distinction matters more here than it does in some home jurisdictions, because the cost, the timeline and the level of judicial intervention are very different depending on which route you end up on.

A mutual-agreement divorce is the faster, cheaper, less painful option. Both spouses sign a single document called a convenio regulador — the regulatory agreement — which sets out everything the court needs to approve: custody of any children, the visitation schedule, child maintenance, spousal maintenance if any, use of the family home, and the division of matrimonial property. That document goes in front of a judge (or, where there are no minor children, a notary) and is approved as a whole. The whole process typically takes two to four months once the paperwork is ready. Both spouses can instruct the same lawyer if they prefer, which keeps fees down.

A contested divorce runs when the couple cannot agree. One spouse files a divorce petition (demanda de divorcio) and the other responds. A judge takes evidence, hears from both sides, and issues a ruling that decides the same questions the convenio regulador would have answered — but decides them without either spouse’s consent. Contested proceedings can take nine to eighteen months and sometimes longer, cost considerably more, and produce outcomes neither side would have negotiated for themselves. Wherever we can, we work to get a contested case settled before judgment, or converted into a mutual-agreement procedure once the sharp edges have come off. Most cases that start contested end up resolved by agreement.

Spain abolished the need to prove fault in 2005. You do not need to prove adultery, cruelty, or irreconcilable differences. Three months of marriage is the only cooling-off period, and after that either spouse can file for divorce unilaterally without giving a reason. That liberal starting point is often a surprise to British and American clients used to more restrictive home-country grounds.

Legal separation — why it still exists

Alongside divorce, Spanish law retains a separate concept of legal separation (separación legal). A separation suspends the duty to live together and divides assets, but does not end the marriage. In practical terms it is used mainly by couples whose religious convictions make divorce difficult, or by spouses who want the financial consequences resolved now but aren’t yet ready to end the marriage. For most expat clients divorce is the cleaner choice, but separation remains a valid route and sits alongside the mediation and collaborative options below.

Children: parental authority, custody and contact

Spanish family law draws a distinction that catches a lot of foreign parents by surprise. Patria potestad — parental authority — is the legal right and responsibility to make major decisions about a child’s life: schooling, medical treatment, religion, where they live. It is almost always shared between both parents after divorce, even when day-to-day custody isn’t. Guarda y custodia — custody — is the day-to-day arrangement: who the child lives with, and what contact the other parent has.

Spanish courts have shifted markedly towards shared custody (custodia compartida) over the last decade. It is now the outcome in roughly half of contested cases and more where parents agree. The precise shape — week-on/week-off, a two-week rotation, term-time with one parent and holidays split, a bird’s-nest arrangement — depends on the ages of the children, the geography of the parents, and the quality of the co-parenting relationship. Sole custody with visitation still happens where shared custody isn’t workable, but it is no longer the default.

Child maintenance (pensión de alimentos) is calculated on a formula that takes account of each parent’s income, the cost of supporting the child, and the distribution of time. Most Spanish courts use a reference table published by the General Council of the Judiciary, adjusted for the region. Spousal maintenance (pensión compensatoria) is separate and is awarded only where one spouse will suffer a genuine economic imbalance from the divorce — it is not automatic and is increasingly time-limited.

The practical effect of all this is that there is almost always a negotiated middle ground that is better than what either parent would get in a contested hearing. Our job, when we can, is to find it — calmly, and without burning through the goodwill that the children will still need their parents to have for the next fifteen years.

International family law — when more than one country is involved

Most of our family-law clients have lives that touch two or three jurisdictions. A British couple living in Marbella with children at a local school, a UK property, and pensions in sterling. An American family where one parent has moved back to the US mid-divorce. An Irish citizen whose Spanish spouse wants to relocate to Ireland with the children. A French-British marriage registered in Gibraltar that now wants to divorce in Spain. Each of these raises questions that pure-domestic Spanish family lawyers aren’t set up to answer, and that’s where our cross-border practice sits.

Two EU regulations do most of the heavy lifting. Brussels II ter (Regulation 2019/1111, in force since August 2022) decides which country’s courts have jurisdiction over divorce, custody and parental responsibility, and how judgments are recognised and enforced between member states. Rome III (Regulation 1259/2010) decides which country’s substantive law applies to the divorce itself — the couple can often choose, and the choice can materially change what maintenance and property outcomes look like. For the UK, post-Brexit, these regulations no longer apply bilaterally and we rely on the Hague Conventions and domestic recognition rules instead. Getting this analysis right at the start decides where the case runs and under which law — and it is the single most important strategic question in any cross-border family case.

Marriage, prenups and matrimonial property

Getting married in Spain as foreigners is straightforward on paper and slow in practice. The civil ceremony is available to non-residents, same-sex couples, and mixed-nationality couples on equal terms, but the paperwork — certificates of no impediment, sworn translations, apostilles, hearings at the Civil Registry — reliably takes three to six months and sometimes more. We handle the full file: documentation, translations, registry applications, Civil Registry hearing, and post-ceremony registration. For couples who want the ceremony in Spain but the legal marriage elsewhere, there are cleaner options we can walk you through.

The default matrimonial property regime in most of Spain is sociedad de gananciales — a community-property regime under which income and assets acquired during the marriage are jointly owned, irrespective of whose name is on the title. That is fine for some couples and disastrous for others, particularly where one spouse brings significantly more capital into the marriage, where there are children from a previous relationship, or where the couple’s home country assumes separate property as the norm. The alternative is separación de bienes — a separation-of-property regime — which is the default in Catalonia, the Balearics, Aragon, Navarre and the Basque Country, and which can be elected elsewhere through a capitulaciones matrimoniales deed signed before a Spanish notary.

A Spanish capitulaciones can do the job of a prenuptial or postnuptial agreement. It can fix the property regime, protect specified assets, regulate what happens to the family home, and carry over provisions from a home-country prenup into something Spanish courts will recognise without argument. It has to be notarised and, where it affects the marriage, registered at the Civil Registry alongside the marriage itself. For international couples with any real asset base, getting this done properly before the wedding — or updating it post-marriage — is one of the highest-leverage pieces of planning we do.

Adoption, guardianship, surrogacy and civil registry

Beyond divorce and marriage, family law in Spain covers a long tail of work that touches most expat families at some point. Adoption is heavily regulated and, for international cases, requires coordination between the Spanish administration and the authorities of the child’s country of origin. Guardianship (tutela) is needed where a minor loses both parents or where an adult loses legal capacity — the 2021 reform of legal capacity law changed the framework significantly and we advise regularly on how it now works in practice. Surrogacy is not legally recognised in Spain itself, but Spanish authorities do recognise foreign surrogacy arrangements in limited circumstances, and there is a technical route through filiation registration that we can walk clients through. Name and surname changes, corrections at the Civil Registry, recognition of foreign civil status documents, Libro de Familia applications — all of this is everyday work in our practice and we handle it end to end.

Why the stakes matter

Family-law cases are different from most other legal work because the downside isn’t just financial. A poorly drafted convenio regulador that doesn’t anticipate a move back to the UK can lock a parent into a custody arrangement that makes relocation impossible. A missed Rome III election can mean Spanish community-property rules apply to a couple who assumed their English-law marriage would be respected. A prenup that hasn’t been properly transposed into Spanish form can turn out to be unenforceable at the worst possible moment. These aren’t hypothetical — we see each of them regularly, usually in cases where the client had used a generalist, a translator, or a do-it-yourself online service the first time around.

Our entire family-law practice is built around avoiding that. Bar-registered family lawyers, cross-border specialists who understand English, Scottish, American, Irish and Canadian law well enough to map it onto Spanish procedure, and an approach that treats every case as the personal, private matter it is. When the instruction comes, we move quickly. When it doesn’t, we never push.
