A pareja de hecho (registered domestic partnership) and a marriage look almost identical in everyday life in Spain: both can secure residence for a foreign partner, and both give you the same 15 days of paid leave. The difference shows up when one partner dies, when it’s time to file taxes or when one of you wants Spanish citizenship.
That’s where marriage gives you rights automatically and a pareja de hecho gives you only some, and with conditions. Without a will, a pareja de hecho partner inherits nothing in most of Spain, and the survivor’s pension comes with requirements many couples only discover too late.
In this guide, you’ll find a table with every difference and how the survivor’s pension, inheritance and income tax work. You’ll also see what changes when one partner is a foreign national and how to decide based on your situation.

In 30 Seconds
- Governing law: marriage is governed by the Civil Code across Spain; a pareja de hecho, by the law of each autonomous community (Spain’s regions).
- Inheritance and survivor’s pension: a pareja de hecho partner doesn’t inherit without a will under common Spanish law, and the pension requires 2 years of registration and, as a rule, 5 years of living together.
- Taxes: only married couples can file a joint tax return.
- Immigration: in the pareja de hecho vs. marriage comparison, the gap is small for residency and huge for citizenship: 1 year married versus 10 years of residency as the general rule.
What Is a Pareja de Hecho and How Is It Different From Marriage?
A pareja de hecho is a stable union of two people who live together in a marriage-like relationship without marrying and formalize it in a public registry or a notarized deed. Its legal effects depend on each region’s law, because Spain has no national domestic partnership law.
What it isn’t: simply living together. An unregistered couple isn’t a pareja de hecho in the eyes of the law, and almost every right in this article depends on that registration. It isn’t a “civil wedding without the ceremony” either: the real difference lies in the rights each status grants by law.
Is a Pareja de Hecho a Marital Status?
No. If you register as a pareja de hecho, you’re still single, divorced or widowed in the Civil Registry. Marriage does change your marital status. That’s why you can never be married and registered as a pareja de hecho at the same time.
Pareja de Hecho vs. Marriage in Spain: Comparison Table
The differences cluster in five areas: inheritance, survivor’s pension, taxes, property regime and citizenship. This table compares a domestic partnership in Spain with marriage under the rules in force in October 2026.
| Issue | Marriage | Pareja de hecho |
|---|---|---|
| Governing law | Civil Code, the same across Spain | Each region’s own law |
| How it’s created | Marriage file and ceremony, recorded in the Civil Registry | Registration with the regional or municipal registry, or a notarized deed where the law allows it |
| Marital status | Married | Unchanged |
| Property regime | Community property by default under common law, unless you sign a prenup | None by default: only what you agree on |
| Income tax (IRPF) | Joint tax return available | Always individual; only one partner can file with the children |
| Inheritance without a will | The surviving spouse is a forced heir and a legal heir | No inheritance under common law; Catalonia treats the partner like a spouse |
| Inheritance tax | Taxed as a spouse | Depends on the region; Madrid, for example, treats a registered partner as a spouse |
| Survivor’s pension | No minimum period, except 1 year if death results from an illness that predates the wedding | 2 years of registration and 5 years of living together (no 5-year rule if you have children together) |
| Paid leave | 15 calendar days | 15 calendar days for the registration |
| Breakup | Separation or divorce, from 3 months after the wedding | Cancellation of the registration under regional law |
| Children | Same rights | Same rights |
| Residency for a foreign partner | Yes, as a spouse | Yes, as a registered partner or a proven stable partner |
| Spanish citizenship | 1 year of residency if you’ve been married to a Spaniard for 1 year | General rule: 10 years (2 for Ibero-American nationals and a few others) |
Put into practical terms: if you’re weighing domestic partnership vs marriage in Spain, look at three rows first. Inheritance, survivor’s pension and citizenship are the ones that change the most for the partner left behind or the partner who needs papers.
Survivor’s Pension for a Pareja de Hecho and for a Spouse
A pareja de hecho partner can receive a survivor’s pension, but with two requirements a spouse doesn’t face: prior registration and a long period of living together.
Under Article 221 of Spain’s General Social Security Act (Ley General de la Seguridad Social), as amended by Law 21/2021, the surviving partner needs:
- Registration at least 2 years in advance: in a domestic partnership registry or a public document, at least two years before the death.
- 5 years of living together: stable, public and uninterrupted right before the death, usually proven through municipal registration (empadronamiento).
- Exception for children in common: if you have children together, the 5 years of cohabitation aren’t required, but you still need the registration.
Since 2022, you no longer have to prove financial dependence on the deceased. Many guides still mention an income cap, but it only applies to deaths before January 1, 2022. The contribution requirements for the person who dies are the same for spouses and partners.
Here’s an example with numbers: Marta and Karim have lived together since 2019, register as a pareja de hecho in March 2025, and he dies in January 2027. There’s no survivor’s pension, because the registration is less than 2 years old, even though they lived together for 8 years. Had they married in March 2025, she could claim it.
A spouse only needs 1 year of marriage if the death results from a common illness that predates the wedding. Not even that applies if they have children together or if their prior cohabitation and marriage add up to more than 2 years.
Can an Unregistered Partner Get a Survivor’s Pension?
No. For Social Security purposes, a couple that just lives together isn’t a pareja de hecho, even after decades registered at the same address. You need the registration or the notarized deed at least two years in advance. It’s the most expensive mistake in this whole topic, because people find out when it can no longer be fixed.
Inheritance, Property and Income Tax: What a Pareja de Hecho Doesn’t Get by Default
Marriage comes with a guaranteed inheritance share for the surviving spouse, a property regime and joint filing; a pareja de hecho comes with none of these.
- Inheritance: under common Spanish law, the surviving spouse is a forced heir. With children, they get a life interest in one third of the estate; with no children or living parents, in two thirds. A pareja de hecho partner is neither a forced heir nor a legal heir: they only inherit what you leave them in a will.
- Property regime: without a prenuptial agreement, a marriage runs under community property under common law. A pareja de hecho has no regime: each partner owns their own assets, except what you buy jointly or agree on before a notary.
- Inheritance tax: it depends on the region. Madrid, for example, treats a registered partner like a spouse and applies the same allowances. Where there’s no such rule, the tax bill can be much higher.
Watch out for regions with their own civil law. In Catalonia, a stable partner inherits like a spouse even without a will, and the Balearic Islands, Navarre and the Basque Country have their own rules. If you live there, the inheritance answer changes.
Can a Pareja de Hecho File a Joint Tax Return?
No. Spain’s Personal Income Tax (IRPF) Law only allows a joint tax return for married couples and, outside marriage, for one parent with their children. In a pareja de hecho with children, one partner can file with them and the other files alone. If your incomes are very uneven, that difference adds up every year.

15 Days of Paid Leave for a Pareja de Hecho or a Marriage
Both give you 15 calendar days of paid leave, a right in place since June 30, 2023.
The rule is Article 37.3.a of the Workers’ Statute (Estatuto de los Trabajadores), as amended by Royal Decree-Law 5/2023. It grants fifteen calendar days “in the event of marriage or registration of a domestic partnership.” The Basic Statute for Public Employees says the same for civil servants. Before that reform, a partner’s leave depended on the collective agreement, and many websites still explain it that way. If your employer says no, show them the article.
Pareja de Hecho or Marriage With a Foreign Partner: Residency and Citizenship
For residency, a pareja de hecho works almost exactly like marriage; for citizenship, it doesn’t shorten anything.
If Your Partner Is Spanish
Since May 20, 2025, Spain’s Immigration Regulation (Royal Decree 1155/2024) has its own residence authorization for family members of Spanish nationals. Spouses can apply, and so can partners registered in a public registry in the EU, the EEA or Switzerland. So can unregistered partners who prove 12 continuous months of living together or have children in common. It lasts 5 years, lets you work as an employee or self-employed, and the application is free; the TIE (Foreigner Identity Card) has a separate fee (€12 as of October 2026). The requirements are in the Ministry’s information sheet.
If Your Partner Is From Another EU Country
Royal Decree 240/2007 applies, along with the EU family member residence card. It covers spouses, partners registered in a public registry in the EU or the EEA, and stable partners with 1 year of living together or children in common. This route also applies to the family member of a Spaniard who has lived in another EU country and exercised free movement there.
One detail worth knowing early: residency through a pareja de hecho is just as valid as through marriage, but the proof is different. A marriage certificate proves everything at once; an unregistered stable partner has to prove cohabitation with municipal registration, leases, joint accounts or children.
If your company is relocating you to Spain as a Highly Qualified Professional or through an intra-company transfer, your partner counts too. Law 14/2013 allows your spouse or the person you share a similar committed relationship with to come with you. We coordinate it through our employee relocation to Spain service, so your partner’s permit moves forward at the same time as yours.
Does a Pareja de Hecho Get You Spanish Citizenship in One Year?
No. Article 22 of the Civil Code cuts the requirement to 1 year of legal residency only for someone who has been married to a Spaniard for a year and isn’t separated. There’s no separate citizenship route for a pareja de hecho: the partner stays on the general timeline of 10 years, or 2 for nationals of Ibero-American countries, Andorra, the Philippines, Equatorial Guinea or Portugal. We cover it in detail in our guide to Spanish citizenship by marriage.
The numbers make the choice clearer: an American who has lived legally in Spain with her Spanish partner for a year can apply for citizenship once she’s been married for a year. As a pareja de hecho, she’d have to wait until she reaches 10 years of residency.
If you’re registering a pareja de hecho with a foreign partner, these are the usual steps. Exact requirements depend on your region; in Madrid, for example, you need 12 months of living together and municipal registration at the same address, and the fee is €82.12 as of October 2026.
- Check your region’s requirements: time living together, municipal registration, and whether it’s done at the regional registry, the city registry or before a notary.
- Get the foreign partner’s marital status certificate: a certificate of single status or legal capacity to marry, or the certificate of their previous marriage with the divorce noted.
- Legalize or apostille the foreign documents and have them sworn-translated if they aren’t in Spanish.
- Register at the same address with the advance notice your region requires.
- Submit the application and pay the fee, if there is one, before your appointment.

Ending a Pareja de Hecho vs. Getting Divorced
Ending a pareja de hecho is faster than getting divorced, but it leaves less protection for the partner who comes out worse.
Divorce can be filed 3 months after the wedding, by both spouses or by just one. If there’s a risk to the life, safety or freedom of one spouse or the children, there’s no need to wait. Spousal support under Article 97 of the Civil Code isn’t automatic: it only applies if the breakup creates a financial imbalance between the spouses and leaves one worse off than during the marriage.
A pareja de hecho doesn’t divorce: you ask the registry to cancel the registration, following your region’s procedure. National law doesn’t provide spousal support for a pareja de hecho, so it depends on your region’s law or on what you agreed. Children are treated exactly the same: custody, visitation and child support are decided the same way, because the law doesn’t distinguish between children born in or outside marriage.
Pareja de Hecho or Marriage: Which One Fits Your Situation
There’s no single answer to whether marriage or a pareja de hecho is better. It depends on what you need to protect.
- If you own property or a home in one partner’s name: marriage protects the surviving partner more. If you prefer a pareja de hecho, make wills and sign agreements before a notary.
- If one of you is a foreign national who wants Spanish citizenship: the gap between marrying and registering can be 9 years.
- If you only need residency: a registered domestic partnership, or even a proven stable relationship, is usually enough.
- If you want flexibility: a pareja de hecho is simpler to set up and to end without a divorce, in exchange for fewer automatic rights.
Before you decide, it’s worth checking what rights a pareja de hecho has in your region. The same registration doesn’t have the same effects in Madrid as in Catalonia.
Knowing the differences is only half the decision. The other half is checking what actually protects you based on your region, your assets and your nationalities. At ILLAY Legal, we look at whether marrying or registering makes more sense for you and when the foreign partner can apply for citizenship. We handle their residence through our family reunification service, 100% online and in your language. Tell us your nationalities, where you live and whether you’re registered or married, and we’ll tell you which route protects you most and which documents you’ll need.
Frequently Asked Questions About Pareja de Hecho vs. Marriage in Spain
Can You Register a Pareja de Hecho While Still Married?
No, not while you’re still married to someone else. There’s a detail few people know: some regions, like Madrid, allow legally separated people to register. But the General Social Security Act requires that the partner have no marital tie to anyone for the survivor’s pension. That registration wouldn’t count for the pension until the divorce is final. If your divorce was granted in another country, check that it’s recognized in Spain before you register.
Can You Be a Pareja de Hecho Without Living Together?
Generally, no: a pareja de hecho is defined by living together. What changes from region to region is how long you need to have done it. Madrid requires 12 months of living together and municipal registration at the same address, while in Catalonia a notarized deed doesn’t need any minimum period. Each right also has its own requirement: 5 years of cohabitation for the survivor’s pension, unless you have children together, and at least 1 year, or children in common, for a foreign partner’s residency as an unregistered stable partner.
Is a Pareja de Hecho Valid in Another Region of Spain?
Your registration stays valid, but its civil effects depend on the law of the registry where you signed up. What you can’t do is be registered in two regional registries, or two municipal ones, at the same time. For Social Security, registration in any regional or municipal registry counts, as does a notarized deed. If you move, check what your new region recognizes, especially for inheritance tax: Madrid, for example, accepts registrations from other authorities’ registries if one partner lives there.
If I Took Leave for Registering a Pareja de Hecho, Do I Get It Again When We Marry?
The law doesn’t say. The Workers’ Statute grants 15 days for marriage or for registering a domestic partnership, but it doesn’t address taking both with the same person. We haven’t found an official position issued after the 2023 reform, and at least one court denied it before then based on a collective agreement. Check your collective agreement first and, if it’s silent, request it from your employer in writing, explaining that the wedding is a separate event from the registration.
How Does a Pareja de Hecho Work in Catalonia?
In Catalonia it’s called a stable partnership (pareja estable), and it’s governed by Catalonia’s own Civil Code. It exists if you’ve lived together for more than 2 years in a row, if you have a child together while living together, or if you formalize it in a notarized deed. Its biggest difference from the rest of Spain is inheritance: without a will, a stable partner inherits like a spouse. Income tax, citizenship and the survivor’s pension follow national rules, so those differences from marriage remain.
Where Can I Register a Pareja de Hecho in Spain and How Much Does It Cost?
At your region’s domestic partnership registry, at your city’s registry if it has one, or, where the law allows it, before a notary in a notarized deed. The cost varies: in Madrid, basic registration is €82.12 as of October 2026, other regions charge different amounts, and the notary charges their own regulated fee. Before paying, check the current amount on your region’s e-portal, along with the documents you’ll need if one of you is a foreign national.
Is Marriage or a Pareja de Hecho Better for Couples With Children?
For the children, it makes no difference: they have exactly the same rights, and custody is decided the same way. The difference lies in protecting the surviving parent. With children in common, a pareja de hecho partner doesn’t need 5 years of cohabitation for the survivor’s pension. But they still don’t inherit without a will under common law and can’t file a joint tax return. If you choose a pareja de hecho, make wills as soon as possible and review whose name your home is in.
