Registering as a pareja de hecho in Spain: requirements and effects

A pareja de hecho is the stable, free, public and well-known union of two people in an emotional relationship comparable to marriage, regardless of their sex. It is not a marriage and it is not solemnised before a judge: it is proved by registration in a public register.

Spain has no single national law and no national register of parejas de hecho. Each comunidad autónoma (autonomous region), and some town halls, has its own register and its own rules, so the requirements, the documents and the effects depend on where you register.

You can register with the register of the comunidad autónoma where you live or with that of the town hall where you are empadronado, that is, listed on the padrón (the municipal population roll). You cannot appear at the same time in two regional registers or in two different municipal ones. Managora identifies the register that applies to you and handles the registration for you.

As a general rule, both members must be of legal age or emancipated minors, be capable of giving consent, not be bound by a marriage and not be registered as a pareja de hecho with another person. They also cannot be relatives in the direct line by blood or adoption, nor collateral relatives within the degree set by each register: the most usual limit is the second degree, although some regions extend the ban to the third degree by blood.

Almost every register requires residence or empadronamiento (registration on the local padrón) in its territory. Some regions also ask for a minimum period of prior empadronamiento before they will accept the application (in Cantabria, for example, it is 6 months).

You must also prove that the relationship is stable. The usual way is to show continuous cohabitation (often of at least 1 year) or to have children in common. As these periods and conditions vary between regions, Managora checks the exact requirements of the register that applies to you before filing.

The basic documents usually include: the register's application form, the DNI (Spanish national ID), NIE (foreigner identification number) or passport of both of you, a recent certificado de empadronamiento (proof of registration on the local padrón), a civil status certificate (fe de vida y estado) from the Registro Civil (the Spanish Civil Registry) showing that neither of you is married, and a declaración responsable (a signed statement made under your own responsibility) confirming that the requirements are met.

To prove that you live together, additional documents may be required, such as joint empadronamiento, the libro de familia (family record book) if you have children in common, or a documento público (a document formalised before a notario, a Spanish notary, or another public official). Some registers also require both of you to appear in person, sometimes with witnesses.

Managora gathers and checks all the documents, prepares the application in line with the register that applies to you and files it for you, telling you only what you have to sign or provide in person. You can check the current price of the service on the procedure page.

A pareja de hecho and a marriage are not equivalent. Marriage is a civil institution that operates at national level with uniform effects across Spain; a pareja de hecho depends on regional rules and does not automatically create the same rights.

In IRPF (Spanish personal income tax) the difference is clear: the members of a pareja de hecho cannot file a joint tax return as spouses do. Only when there are children in common can one of the parents form a family unit with the children and file jointly, while the other files individually. Two joint returns can never be filed.

Marriage also sets a matrimonial property regime (community of property or separation of assets) and gives the spouse inheritance rights where there is no will. A pareja de hecho does not automatically create a property regime and, in much of Spain, does not inherit if there is no will, so it is worth planning ahead. On the other hand, ending it is simpler: you just cancel the registration, with no need for a divorce.

In the Impuesto sobre Sucesiones y Donaciones (Spanish inheritance and gift tax), whether a pareja de hecho is treated in the same way as a spouse depends on the comunidad autónoma. Several regions give registered parejas de hecho the same reductions and allowances as spouses, but they require precisely that registration in order to apply them. National rules do not treat them as equivalent, so without registration and without a regional provision you are taxed as a person with no family relationship.

In employment matters, being registered as a pareja de hecho gives access to certain leave and rights recognised for a partner (for example, leave for the death or serious accident of a relative), on the terms set by the Estatuto de los Trabajadores (the Spanish Workers' Statute) and the applicable collective agreement.

Registration is therefore not a mere formality: it is what activates most of the tax and employment effects. Managora makes sure the couple is correctly registered so that you can enforce those rights.

If one of you is a Spanish or European Union citizen and the other is a foreign national, a registered pareja de hecho allows you to apply for the residence card for a family member of a Union citizen. For this, the register must be a public register that prevents double registrations; failing that, a duly proven durable relationship can be relied on. This is one of the main routes by which a foreign partner can live and work in Spain.

As for the pensión de viudedad (widow's or widower's pension), the Ley General de la Seguridad Social (the Spanish Social Security Act) recognises the right of the surviving partner. You must have been registered as a pareja de hecho (or have formalised it in a public document) at least 2 years before the death, and prove stable cohabitation of at least 5 years. Since the reform that came into force in 2022, the old requirement of financial dependence and the income limit no longer apply.

These rights mean that registering as soon as possible has practical consequences: the 2-year period for the pensión de viudedad is counted from the date of registration. Managora handles the registration as quickly as possible and guides you on the documents you will need later on.
