Married to a Portuguese citizen? How residency and nationality actually work in 2026
Marriage or a civil partnership with a Portuguese citizen opens the door to residency (via AIMA) and to nationality after 3 years — but the 2026 law raised the bar. The full guide.
Yes — marrying or living in a recognised partnership (união de facto) with a Portuguese citizen is still one of the most direct routes to legal residency and, later, to nationality. But they are two separate processes, handled by two separate institutions, and the nationality law that took effect in 2026 made the second one stricter. Let’s take it step by step.
How do you get residency through marriage or a civil partnership?
The foreign spouse or partner of a Portuguese citizen applies for residency through family reunification, handled by AIMA. For a marriage, the certificate does the talking; for a união de facto you must prove the relationship — as a rule, at least two years of shared life, evidenced by things like a joint lease, shared bills or a declaration from your local parish council. The requirements and application are set out on AIMA’s official family reunification page, and we’ve walked through how reunification works in practice, deadlines and paperwork included.
How many years of marriage do you need for Portuguese nationality?
Three — and the new law did not touch that number. Anyone married to a Portuguese citizen for more than three years can declare their wish to become Portuguese, in a process that runs through the civil registry (IRN), not AIMA. A união de facto counts the same way, with one extra step: you first need a civil court to formally recognise the partnership, and only then does the nationality request go in. The official details are on the Justice ministry’s portal.
What changed with the 2026 law?
The waiting period stayed; the filter tightened. Organic Law 1/2026, in force since May, beefed up the so-called opposition regime: public prosecutors can oppose the acquisition when there is no effective connection to the Portuguese community, and what counts as proof of that connection moved closer to the naturalisation standard — in practice, living in Portugal, speaking Portuguese and having your life anchored here all carry more weight. Criminal-record scrutiny also got stricter. The law does build in two explicit safety valves: no opposition is possible when the marriage or partnership has lasted more than six years, or when the couple has children with Portuguese nationality. For the wider picture, see our guide to the 2026 nationality law.
One warning that saves heartache: marriages of convenience are not a shortcut, they’re a crime — where there are signs a marriage or partnership existed only to obtain papers, the permit can be cancelled and the case sent to court.
How long must I be married before applying for nationality?
More than three years of marriage (or of a judicially recognised partnership). The request is a declaration at the civil registry and has no minimum residence-in-Portugal requirement — but effective connection to the country weighs in the assessment, especially since 2026.
Does a união de facto count the same as marriage?
It does, with one extra step: for nationality you need judicial recognition of the partnership (more than three years); for residency via AIMA, two well-documented years of shared life are generally enough.
Do I need to speak Portuguese?
For residency, no. For nationality, proving your connection to the community got tougher under the 2026 law — and a language certificate is the most solid evidence; the usual route is the CIPLE exam, explained here.
Is the process at AIMA or the IRN?
Both, for different things: residency and reunification at AIMA; nationality at the IRN (civil registry). They’re independent — you can hold residency forever without ever requesting nationality.
