Dutch Citizenship Through Marriage: The 3-Year Rule Explained

Most people know that living in the Netherlands for five years qualifies you to apply for permanent residence. Fewer people know that if your partner is a Dutch national, you can apply for Dutch citizenship after just three years — not five — and keep your original passport in the process. This is one of the most significant and least publicised benefits of the partner visa route.

The Standard Route vs. the Partner Route

For most foreigners, Dutch naturalization requires five continuous years of legal residence in the Netherlands, a passed civic integration exam, and renunciation of your original nationality. The Netherlands does not generally permit dual citizenship.

The partner route is different on two counts: the residency requirement is shorter, and dual citizenship is permitted.

Residency requirement: Partners and spouses of Dutch nationals can apply for naturalization after three years of marriage or registered partnership, provided you have been living together continuously for at least three years. The cohabitation does not have to be in the Netherlands for the entire period — but you cannot be living in your own country of nationality during those three years.

Dual citizenship: The Netherlands generally requires you to give up your original nationality when naturalizing. However, this requirement is waived if you are married to or in a registered partnership with a Dutch national. You can become Dutch while keeping your current passport.

What You Need to Qualify

To apply for Dutch citizenship under the accelerated partner route, you must meet all of the following:

3 years of marriage or registered partnership. Cohabitation without legal recognition does not qualify. You need either a marriage certificate or a registered partnership certificate registered with a Dutch municipality.

3 years of continuous cohabitation. You and your Dutch partner must have been living together for those three years. The IND checks this through BRP registration records — both names at the same address for the required period. Periods of separation (one partner abroad for work, for example) can be acceptable if they are temporary and you can demonstrate the shared household remains the primary residence.

Legal, continuous residence in the Netherlands. Generally, you need to have been living in the Netherlands with a valid residence permit for the period. The exact years-in-the-Netherlands requirement for the partner route is at least one of the three partnership years spent in the Netherlands.

Passed civic integration exam. You must have completed the inburgeringsexamen at the required level (B1 under the 2021 Act) before you apply. The naturalization decision will be rejected if the integration obligation is incomplete.

Clean criminal record. No convictions in the four years preceding the application that resulted in an unconditional custodial sentence, community service order, or fine of a certain threshold. Minor traffic fines do not disqualify you; serious criminal offences do.

Still on the partner visa itself? Before thinking about citizenship, you need to be in the Netherlands legally. The Netherlands Partner/Family Visa Guide covers the full partner visa application process from document preparation through arrival.

The Application Process

Naturalization applications are submitted to your municipality, not directly to the IND. The IND takes over the assessment from there. The application fee in 2026 is €1,139 for a single applicant or €1,454 for a couple applying together (if both need to naturalize).

The processing time for naturalization applications has been lengthy in recent years. Applicants should expect at least six to twelve months between submission and a decision. During this period, you continue to live in the Netherlands normally on your residence permit, which remains valid.

If approved, you receive a notification letter and are invited to attend a naturalization ceremony at your municipality. At the ceremony, you sign the naturalization declaration. The moment you sign is the moment you become Dutch.

Registered Partnership vs. Marriage

Both marriage and registered partnership qualify for the accelerated three-year path. The practical difference: a registered partnership can be entered at a Dutch municipality without the religious or cultural formality of a marriage, and it carries the same legal rights and obligations in the Netherlands as marriage, including for immigration purposes.

For IND purposes, a registered partnership is treated identically to a marriage throughout the partner visa and naturalization process.

What Happens If You Divorce Before Naturalizing

If your marriage or registered partnership ends before you complete the naturalization process, you lose access to the three-year partner route. You would need to qualify for naturalization under the standard five-year route instead — assuming you still have sufficient continuous legal residence.

If your residence permit was dependent on the relationship and was revoked after the breakup, the five-year clock for naturalization resets from when you obtain an independent permit. This is one of the reasons completing the naturalization process as soon as you are eligible makes practical sense.

Retained Dutch Citizenship: A Note on Children

Children born to a Dutch parent are Dutch from birth, regardless of where they were born. If your Dutch partner recognises a child born during the relationship, that child holds Dutch nationality automatically. The child's Dutch citizenship is independent of your own naturalization process.

Your own Dutch citizenship, once obtained, is permanent unless renounced. It does not lapse if you later divorce your Dutch partner or spend extended periods outside the Netherlands.
