I have a Dutch mother and a non-Dutch father

If you have a Dutch mother and are not a Dutch citizen, but would like to acquire Dutch nationality, the following information is important to you.

Question: I was born of a Dutch mother and a non-Dutch father before 1 January 1985. Am I a Dutch citizen?

Answer: No. However, if you were born before 1 January 1985 and at the time of your birth your mother was a Dutch national and your father was not, and if you have not previously acquired Dutch nationality, you may as of 1 October 2010 make a declaration opting for Dutch nationality. This option is laid down in an Act amending the Netherlands Nationality Act published in the Bulletin of Acts and Decrees (Staatsblad) on 29 June 2010. The text of the amendment can be found (in Dutch) at: https://www.officielebekendmakingen.nl/stcrt-2010-10196.html

Question: How can I acquire Dutch nationality?

Answer: As of 1 October 2010, you can make a declaration opting for Dutch nationality, in person, at the Dutch embassy or consulate-general in your country of residence. You must provide evidence that:

  • you were born before 1 January 1985; and

  • your mother possessed Dutch nationality at the time of your birth, and

  • your father was not a Dutch national at the time of your birth.

A check will also be carried out to verify that you have not previously acquired or lost Dutch nationality.

Question: What documents must I submit?

Answer: To make a declaration opting for Dutch nationality, you must complete and submit an information form. You will also need valid identification and a birth certificate, which should be legalised if necessary. Consular staff will tell you what other documentation is required, based on the information form.

Question: Until what date can I make a declaration opting for Dutch nationality?

Answer: The Act does not set an end date for the opting-in rule.

Question: Not I, but my father or mother was born of a Dutch mother and a non-Dutch father before 1 January 1985. Am I a Dutch citizen?

Answer: No, but if your father or mother opted for Dutch nationality under this rule, you may also acquire Dutch nationality by making your own declaration that you wish to become a Dutch citizen. You may also do so if your father or mother died before being able to use the opting-in procedure. You can also follow this procedure if you were acknowledged by your father before the age of seven, or if you were acknowledged when you were between seven and 18 years old by a man who submitted evidence to prove that he is your biological father.

Question: As a minor, I was officially adopted by a woman of Dutch nationality in the Netherlands, the Netherlands Antilles or Aruba before 1 January 1985. Am I a Dutch citizen?

Answer: No, you did not automatically acquire Dutch nationality by adoption. As of 1 October 2010, you may however make a declaration opting for Dutch nationality, as described above, to become a Dutch citizen.

You can find more information about acquiring Dutch nationality on the website of the Immigration and Naturalisation Service and in their brochures in English.
