One genuine door the 2020 reform opened is reacquisition—a route for people who once held Norwegian citizenship and lost it to get it back, often by a straightforward notification. For some diaspora families, especially those with a more recent Norwegian emigrant, this is a real and valuable possibility. But it is important to be precise about who it serves: reacquisition is for former citizens, not for distant descendants who never held Norwegian citizenship at all. This guide explains the route and its limits.

Always verify your situation with the Norwegian authorities—the UDI (Norwegian Directorate of Immigration)—or a qualified immigration professional before acting.
What reacquisition is
Reacquisition is the process by which a person who previously held Norwegian citizenship and lost it can become Norwegian again. It exists because, before dual citizenship was allowed, many Norwegians lost their citizenship—most commonly by acquiring another citizenship abroad, which under the old rules meant automatic loss. Now that Norway permits dual citizenship, the reason those people lost their citizenship no longer applies, so the law provides a way for them to regain it. Crucially, reacquisition restores something the person once had; it is not a grant of citizenship to someone who never held it.
Reacquisition by notification
For many former citizens, the reacquisition route is refreshingly simple: it can be done by notification (a declaration to the authorities) rather than a full naturalisation application, and it generally does not require passing a Norwegian language test or meeting residence requirements. This reflects the logic of the route—the person is regaining a citizenship they previously held, not being assessed as a newcomer. The notification process is administered by the UDI, which sets out the conditions and documentation; where the conditions are met, it is a far lighter process than naturalisation from scratch.
Who qualifies
The essential qualification is that you must be a former Norwegian citizen—someone who genuinely held Norwegian citizenship at some point and then lost it. The most relevant case for diaspora families is a person who was a Norwegian citizen (for instance, born in Norway, or born abroad to a Norwegian parent) and who lost that citizenship by naturalising in another country before 2020, when doing so caused automatic loss. Such a person may now be able to reacquire their Norwegian citizenship by notification, and to hold it alongside the citizenship they acquired abroad—something the old single-citizenship rule forbade.
Why it doesn’t help distant descendants
Here is the crucial limit, and the reason reacquisition is not the diaspora windfall some imagine. Reacquisition restores citizenship to those who held it and lost it—it does not confer citizenship on descendants who never held it. The great-grandchild of a nineteenth-century emigrant never held Norwegian citizenship, so there is nothing for them to reacquire; and the emigrant ancestor who did hold and lose it is, in the case of the old emigration waves, long deceased. Reacquisition is therefore mainly relevant to more recent emigrants, or to living people who lost Norwegian citizenship in their own lifetimes—not to the descendants of those who left generations ago.
The retention-loss cases
One further group may find reacquisition relevant: those who lost citizenship under the retention rule—people born abroad to a Norwegian parent who lost their Norwegian citizenship at 22 for want of a sufficient connection to Norway. Because such a person did hold Norwegian citizenship (from birth, through their parent) before losing it, they too may fall within the logic of reacquisition or related provisions. Anyone who believes they once held Norwegian citizenship and lost it—whether by naturalising abroad or under the retention rule—should explore their options with the UDI, as the details are fact-specific.
How to explore a reacquisition claim
If you think you may be a former Norwegian citizen, the path forward is to establish two things: that you held Norwegian citizenship at some point, and that you subsequently lost it. Documenting your own or your parent’s Norwegian citizenship—through the records and any citizenship or naturalisation papers—is the starting point, after which the UDI can advise whether reacquisition by notification is open to you and what it requires. Because these cases turn on precise facts and dates, this is very much a question for the authorities or a qualified adviser rather than assumption.
A real but narrow route
Reacquisition is a genuine and generous route—often just a notification, with no language test—for the specific people it serves: former Norwegian citizens who lost their citizenship, most relevantly by naturalising abroad before 2020 or through the retention rule. For them, the 2020 reform is a real opportunity to regain a Norwegian citizenship they once held, and to keep it alongside another. But it is narrow, restoring what was lost rather than granting what was never held, so it does not reach the distant descendants who make up most of the diaspora. Knowing which group you fall into is the key to a realistic assessment—and for the many who are not former citizens, the heritage itself remains fully theirs to reclaim.
