The Princess Rule


Children born in wedlock to a Danish mother and a father of foreign nationality during the period of January 1, 1961 to December 31, 1978 did not obtain Danish nationality by birth.

As an alternative, Danish mothers were offered to make a declaration by which their child obtained Danish nationality, cf. s. 2(2) of Act No. 117 of March 29, 1978.

Children born during this period whose mother did not make a declaration to this effect may apply for Danish nationality by naturalization according to the “Princess Rule”.

Applying under the Princess Rule, does not require residence in Denmark at the time of applying, however you must have resided in Denmark for either 3 months continuously or visited for a cumulative 12 months prior to having turned 22 years old.

You are also exempt from passing the Danish citizenship test, including the language test. However, for a successful application, you must be able to take part in an ordinary conversation in Danish with a Danish-speaking national from the Embassy of Denmark in Ottawa.

In addition, it is a condition that the other requirements for obtaining Danish nationality by naturalization are fulfilled. If you have been sentenced to imprisonment longer than 18 months, you cannot acquire Danish nationality by naturalization. If you have been convicted of other offences, you cannot be naturalized until after a certain period of time has passed. Finally, you may not have a debt to the Danish authorities.

Please note that if your application for Danish nationality under the Princess Rule is successful, this does not extend to any children you may have when you reside outside of Denmark.


Step 1: Complete Application Form and Payment of Processing Fee
A completed application form and payment of the non-refundable processing fee is a requirement for an admissible application.

The fee must be paid directly to the Ministry of Immigration and Integration.

Step 2: Collect Documents
A document checklist can be found in “bilag 2” of the application form.
In addition to the document checklist in bilag 2, you must enclose the following documents with your application:

  • Your birth certificate, which must include your mother’s name.
  • Your mother’s birth certificate
  • Your parents’ marriage certificate
  • A declaration from your mother stating whether she ever applied for or acquired a foreign nationality by application. The declaration should read as follows: "I, the undersigned, solemnly declare that I have never applied for nor acquired a foreign nationality". If your mother passed away, you need to enclose the death certificate.
  • If you have been studying or working in Denmark: copies of certificates etc. 

Please note that it is your responsibility to ensure that all necessary documents are submitted. It is strongly recommended that you contact the Nationality Division at the Ministry of Immigration and Integration for any updates regarding the submission of correct documents.
