You are not married, but your partner is Spanish. You want to live together in Spain. The good news: marriage is not a legal requirement. The less simple news: the proof required for unmarried couples is more demanding than many people expect, and where the application fails, it usually fails here.
Here is how this route works, what the law actually requires, and what you need to get right.
The Legal Framework Has Changed: for the Better
Since May 2025, a new framework for the residency of family members of Spanish nationals has been in force, introduced by Real Decreto 1155/2024. The new Reglamento amplifies the concept of family and allows access to this authorisation in more situations than before. For unmarried couples specifically, this matters, because the current law explicitly recognises three separate pathways depending on your situation.
Three Pathways for Unmarried Partners
1. Registered partner (pareja registrada)
If you are a non-married foreign partner over 18 and your relationship has been registered in a public register established in an EU member state, an EEA country, or Switzerland, and that registration has not been cancelled and was not entered into fraudulently, you can access this route. This is the strongest position for an unmarried couple: it is treated similarly to marriage for residency purposes.
2. Stable partner with proven cohabitation (pareja estable)
This is the most commonly used route. You must demonstrate a stable relationship equivalent to a marital relationship. The law defines this as a cohabitation of at least 12 continuous months, inside or outside Spain. You do not need to be registered anywhere, but you do need to prove the relationship convincingly.
3. Common children
If you have children in common with your Spanish partner, this is also accepted as proof of a stable relationship, even without the twelve months of cohabitation. This pathway is cleaner and often faster to document.
What the Authorisation Gives You
This authorisation is valid for five years and allows you to work as an employee or as self-employed anywhere in Spain, without any additional labour formalities.
It is one of the most complete residency authorisations available for non-EU nationals, and it is significantly stronger than most visa categories.
Where Applications for Unmarried Partners Go Wrong
This is where the process becomes genuinely difficult, and where professional guidance makes the clearest difference.
Proving twelve months of cohabitation is not straightforward. The administration does not simply accept a declaration. Cohabitation is specifically required for stable couples without common children. In practice, you need a consistent and corroborated documentary record: joint rental contracts, empadronamiento at the same address, shared bank accounts, correspondence at a shared address, travel records, photographs, and, where possible, third-party witness statements or declarations.
Consular inconsistency is a real problem. Some consulates are currently creating difficulties and requesting that the marriage be registered, or requiring one year of cohabitation specifically as a formal threshold, rather than treating it as one element of a broader evidential picture. In these cases, appealing the decision is recommended.
This is not what the law says. It is, however, what some applicants encounter. Knowing how to push back, and having the legal grounding to do so, is the difference between a resolution and a dead end.
The declaration of absence of other partner is mandatory. The Spanish partner must provide a signed declaration confirming that no other spouse or partner resides with them in Spain. Small administrative omissions like this, if missed, can stall the entire application.
Document authentication requirements are strict. All foreign documents, like birth certificates, foreign registration records, cohabitation certificates from other countries, must be apostilled and accompanied by sworn translations into Spanish. Documents issued by countries that are not Hague Convention signatories require full consular legalisation.
The Specific Doubt That Stops People from Applying
Many unmarried couples delay, sometimes for years, because they are unsure whether what they have is enough to prove the relationship. The answer depends entirely on how you build and present the evidence. A relationship that is genuine but poorly documented will fail. The same relationship, documented with a structured dossier, will succeed.
If you are asking whether your situation qualifies, the answer is almost certainly: it might, and what determines the outcome is not the relationship itself, but how the file is constructed.
