Marriage and pareja de hecho in Spain: documents, the two routes and the effect on residence
You can formalise a couple in Spain by marriage or by pareja de hecho (registered partnership). This guide explains the two routes, the documents foreigners need (certificado de capacidad matrimonial, apostille + sworn translation), and the real effect on residence (familiar de la UE / reagrupación) and nationality.
Marriage vs pareja de hecho
Matrimonio: civil (or religious with civil effect) registered at the Registro Civil, after an expediente matrimonial.

Pareja de hecho: a registered domestic partnership; the registry and the requirements (cohabitation, joint padrón) vary by autonomous community.
Both can have effects on residence, tax and inheritance — but marriage and pareja de hecho are not identical for every purpose.
Who can (foreigners, same-sex)
- Foreigners can marry or register a pareja de hecho in Spain; same-sex marriage is legal.
- For marriage, foreigners usually need a certificado de capacidad matrimonial or proof of single status from their country.
- For pareja de hecho, requirements (cohabitation period, being empadronados together) vary by comunidad.

Effect on residence and nationality
- With an EU citizen (incl. Spanish): the foreign partner can apply for the tarjeta de familiar de ciudadano de la UE.
- With a non-EU resident: it can support reagrupación familiar.
- If, when applying for nationality, you have been married to a Spanish citizen for 1 year and are not legally or de facto separated, the residence period is reduced to 1 year. It is a route, not instant residence — and marriages of convenience are scrutinised.
Documents you need
- Valid passports / NIE/TIE and recent municipal registration (empadronamiento).
- Birth certificates and, for marriage, the certificado de capacidad matrimonial / proof of single status.
- Foreign documents usually need an apostille and a sworn translation.
- For pareja de hecho: proof of cohabitation as required by your comunidad.
How to formalise it
- Decide between matrimonio and pareja de hecho for your situation.
- Gather the documents (apostille + sworn translation for foreign ones).
- Marriage: start the acta/expediente matrimonial with the Registro Civil or another competent authority, such as a notary where available. Pareja de hecho: register at your comunidad's registry.
- Complete the ceremony / the inscription.
- If it gives a residence route, apply for the tarjeta de familiar de la UE or the reagrupación.
- Update municipal registration (padrón) if needed and keep the marriage certificate or Registro Civil entry.
Common mistakes
- Thinking marriage = automatic residence — it is a route, not instant.
- Foreign documents without apostille or sworn translation.
- Assuming pareja de hecho equals marriage everywhere — it varies by comunidad and purpose.
- Underestimating the scrutiny of suspected marriages of convenience.
Denied (marriage of convenience)
- If the expediente is denied (e.g. suspected marriage of convenience), there is a recurso — react with evidence of a genuine relationship.
- If pareja de hecho requirements are not met, check your comunidad's exact rules and the cohabitation proof.
