Decisions from Switzerland, the UK or the US: Recognition in Portugal

If you hold a decision from a Swiss, British or American court — a divorce, a ruling about your children, a settlement over property or money — it is natural to assume it simply counts in Portugal. After all, these are close countries with solid, well-regarded justice systems. But the proximity and strength of a foreign court are not what determine whether your decision produces effects here.

The point of this article is a distinction most people only discover at the worst possible moment: decisions from Switzerland, the United Kingdom and the United States generally fall outside the simpler route Portugal reserves for a narrow group of countries. Because of that, they usually have to be recognized through a Portuguese court before they mean anything here.

The simplified route these decisions do not have

For a specific set of countries, there is a regime that lets a foreign decision circulate with almost no friction. Within that group, the states trust one another automatically: a decision made in one is accepted in another with minimal review, and the person holding it has to do very little for it to count.

The difficulty is that Switzerland, the United Kingdom and the United States are not inside that group — each for a different reason. And a decision that comes from outside that circle does not enter Portugal on its own. Not because the justice of these countries is weak, but because the bond that would waive the review is missing. Where that bond is absent, Portugal wants to look at the decision before accepting it. That passage through a Portuguese court is what these three origins have in common.

Switzerland: close to Europe, but outside the system

Switzerland tends to cause confusion. It sits at the geographic heart of Europe, borders countries in the bloc, takes part in many European arrangements — and yet it never joined the group that benefits from the simplified recognition Portugal applies to its closest partners.

The result is that a Swiss decision, however well reasoned, does not enjoy the open door reserved for that circle. For Portugal, it stands in the same position as a decision from any country outside that regime. Someone who divorced in Switzerland, or obtained a ruling there about a child's custody, and assumes it counts immediately in Portugal, is working from an understandable but mistaken expectation. Proximity to Europe is not what opens the door; what opens it is a specific bond that Switzerland, on this point, does not have.

The United Kingdom: what changed after Brexit

For years, a decision from a British court entered Portugal almost unnoticed. The United Kingdom belonged to the same bloc, so its decisions circulated within that regime of near-automatic trust. It was reasonable to assume "it's a British court, so it counts."

Brexit closed that door. When the United Kingdom left the bloc, it stopped being part of that shared circulation of decisions. The change had nothing to do with the quality of British justice; it was a matter of status. Overnight, in legal terms, UK decisions moved from "inside the system" to "outside" it — and a decision from outside has to be recognized by a Portuguese court to produce effects here.

What makes this change treacherous is that it does not appear on your document. A British divorce decree issued after Brexit reads exactly like one issued before. Nothing on the paper warns you that the route it takes into Portugal has changed entirely. Many people only discover the difference when they try to use the decision and it is not accepted.

The United States: a distance that was always there

With the United States, there was no recent rupture — the distance was always there. An American court was never part of the circle of countries whose decisions Portugal accepts almost directly. A US decision has always been, from the Portuguese point of view, in the category of decisions that must pass through a review before they count.

There is also a layer that often surprises people: in the United States, each state has its own judicial system and its own rules. A decision from Florida, California or New York does not come from a generic "US court" but from a concrete state legal order. For Portugal, what matters is that this is a foreign decision that must be recognized — and the way each state decision fits within Portuguese requirements is exactly what calls for careful reading.

Why this is not a mere formality

There is a natural temptation to treat this recognition as paperwork — a form to submit, a box to tick. It is not. Because these three origins fall outside the simplified route, their decisions go through a court process in Portugal, one in which the foreign decision has to fit correctly within Portuguese requirements before it is confirmed. This is the process of recognition and enforcement of foreign judgments, and the outcome depends on how each element of the decision aligns with what Portugal expects to see.

This is where experience makes the difference. Switzerland, the United Kingdom and the United States share the passage through the court, but they reach it by different paths — and each origin brings its own sensitive points. The greatest value of work done well is not in the visible part of the process, but in reading your specific situation correctly: anticipating where the obstacles are and steering the case so it is accepted the first time.

At Sentença sem Fronteiras, the recognition of foreign decisions is our central area of practice. We examine where your decision comes from, identify exactly what needs to be recognized, and carry the process through from start to finish — so a decision that was valid all along finally counts in Portugal too.

Frequently asked questions

Switzerland is a European country. Doesn't my Swiss decision count automatically in Portugal? As a rule, no. Switzerland is not part of the group of countries that benefit from simplified recognition in Portugal. Geographic proximity does not change this: a Swiss decision usually has to be recognized through a Portuguese court.

My UK decision predates Brexit. Do I still need to have it recognized? In most cases, yes, if you now need it to produce effects in Portugal and it was never formally accepted here. The old fast route relied on a bond between the two countries that no longer exists.

The decision came from a specific US state. Does that change anything? For recognition purposes, what matters is that it is a foreign decision that must pass through the Portuguese court. The state legal order of origin shapes the reading of the case, not the need for recognition itself.

Can I deal with this while living outside Portugal? In the great majority of cases, yes. It is not necessary to be in Portugal to start and conduct the recognition of a foreign decision.

Conclusion

Switzerland, the United Kingdom and the United States share something few people anticipate: their decisions fall outside the simpler route Portugal reserves for a narrow group of countries. Switzerland never entered that circle, the United Kingdom left it with Brexit, and the United States was always at a distance. In every case, the practical result is the same — the decision must be recognized through a Portuguese court to produce effects here.

If you hold a decision from one of these countries that needs to work in Portugal, the sensible move is to treat its recognition with someone who works in this area every day — so it is accepted the first time and what the decision settled can finally take effect. That is precisely what we do at Sentença sem Fronteiras.
