Children born in wedlock to a Danish
mother and a foreign father during the period 1st January 1961 to 31st December 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 19th March 1978.
Children born during this period whose mother did not make a declaration to this affect may apply for Danish nationality by naturalisation
according to the “Princess Rule”.
It is a condition that the general requirements for obtaining Danish nationality by naturalisation are fulfilled. This means that an applicant who has been convicted of an offence cannot be naturalised until after a certain period of time, and that the applicant may not owe money to the Danish authorities.
In addition, the applicant must be able to take part in an ordinary conversation in Danish. It is not a condition that the applicant must read or write in Danish.
It is furthermore a condition that the applicant has been staying in Denmark under circumstances indicating some association with the country. In general, one year's stay in total before the age of 22 is required.
In order to obtain Danish nationality by naturalisation, it is furthermore a condition that the applicant renounces his/her previous nationality, in so far as this is possible, unless the applicant lives in his/her country of origin. This means that a Irish national residing in the Ireland does not have to give up his/her Irish nationality to obtain Danish nationality by naturalisation in accordance with the Princess Rule.
