Marrying a Spanish national does not automatically mean applying for the family member of an EU citizen card. Since 20 May 2025 the Immigration Regulation has provided a temporary residence authorisation of its own for family members of Spanish nationals, while the EU family member card belongs to a different regime: that of family members of nationals of other States of the European Union, the European Economic Area or Switzerland.
Two regimes that get confused daily
The confusion has a simple explanation: for years almost any marriage to a Spanish national was described as a "comunitario family card", and the name stuck.
The two now need to be kept apart. Royal Decree 240/2007 governs the regime for citizens of other Member States of the European Union and of the European Economic Area and their family members, and it is within that framework that the card is applied for by a family member who does not hold the nationality of one of those States. Royal Decree 1155/2024, in article 93, provides instead a specific temporary residence authorisation for family members of Spanish nationals.
The difference is not terminological: the requirements to be established and the documentation to be gathered both change. Starting from the wrong form is the most common way of losing months.
The spouse: what actually has to be established
Article 94 of Royal Decree 1155/2024 opens its list of family members with a general condition that governs every case on it and that is easily missed: those in one of the situations it lists may apply provided that they live together. For the spouse, the provision adds that they be over 18, that no agreement or declaration of nullity of the marriage and no divorce has been handed down, and that the marriage was not celebrated in fraud of law.
The same article further specifies that in no case may more than one spouse obtain this authorisation, irrespective of whether the foreign national's personal law permits that form of marriage, and it lays down a separate rule for anyone married in second or subsequent nuptials.
Cohabitation and fraud of law are the two conditions that stop the most files, because neither is settled by producing a certificate: the file may examine whether the relationship is real. It is therefore worth keeping and organising from the outset whatever evidences cohabitation and a shared life, rather than reconstructing it when asked.
Registered partner and stable partner are not the same thing
That same article 94 distinguishes two situations for those who are not married, and the distinction has practical consequences:
- Registered partner: the partnership must be entered in a public register of a State of the European Union, the European Economic Area or Switzerland, and the entry must not have been cancelled. A registration made only in Mexico does not meet this condition.
- Stable partner without registration: as a rule, 12 continuous months of cohabitation analogous to marriage must be established. There is a relevant exception: where there are children in common and the relationship continues, that prior period is not required.
Article 96 of the same Regulation sets out what is submitted: documentation establishing the relationship and, for a stable partner, evidence of the relationship, of cohabitation and, where applicable, of the birth of children in common. That evidence is built up over time.
Your Mexican marriage certificate has to work in Spain
A marriage celebrated before a foreign authority is not taken as known in Spain simply because it exists. Article 59 of Law 20/2011, on the Civil Registry, provides for its access to the Spanish Civil Registry through registration of the certification, provided that the certification has effect in accordance with the Law, and adds that the entry gives evidence of the marriage and of the date and place where it was contracted, and produces full recognition of its civil effects as against third parties acting in good faith.
Form matters too. Article 95 of the same Law requires documents not drawn up in an official Spanish language to be accompanied by a competent translation, and documents issued by a foreign authority to be legalised, save for the exceptions provided. For a Mexican document, the usual route for that legalisation is the apostille.
Put differently: before thinking about the residence authorisation, you need to check that the marriage certificate is in a condition to take effect in Spain.
One year of marriage, one year of residence
It is worth knowing the horizon from the start, because it changes how you plan. Article 22.2.d) of the Civil Code reduces to one year the period of residence required to apply for Spanish nationality for anyone who, at the time of the application, has been married to a Spanish national for a year and is not separated in law or in fact.
The two run together, not one after the other: a year of legal residence in Spain and a year of subsisting marriage, without separation. Those who order their residence properly from the beginning reach that point with a clean file.
Common mistakes
- Applying for the family member of an EU citizen card while married to a Spanish national, when a different regime applies.
- Assuming a Mexican marriage certificate is valid in Spain without apostille or translation.
- Presenting as a registered partnership an entry made outside the European Union, the European Economic Area or Switzerland.
- Claiming stable cohabitation without having kept evidence of the 12 continuous months.
- Applying as a spouse without being able to establish the cohabitation that article 94 requires.
- Not knowing that children in common dispense with that prior period where the relationship continues.
- Counting the year of residence for nationality without checking that the marriage has also been in force for a year.
