Children born abroad outside of marriage to a Danish father and a foreign mother between October 11, 1993, and June 30, 2014, did not acquire Danish citizenship at birth. As an alternative, children born under these circumstances can instead apply for Danish citizenship by being included in a bill on the granting of citizenship without meeting the general conditions. It is a prerequisite that the father had Danish citizenship at the time of the child's birth. Read more about the rules here.
If the parents have since married (before the child turned 18 and unmarried), the child automatically obtains Danish citizenship from the date of marriage. However, children born abroad must apply to retain Danish citizenship before they turn 22.
If a child was born abroad out of wedlock to a Danish father and a foreign mother before October 11, 1993, and the parents remained unmarried, the child cannot obtain Danish citizenship without meeting the general conditions. Children born on July 1, 2014, or later automatically acquire Danish citizenship at birth if the father, mother, or co-mother is Danish, regardless of whether they were born in or out of wedlock.
When applying for Danish citizenship without meeting the general conditions, there is no requirement to be resident in Denmark at the time of application. Nor is there a requirement to pass the Danish citizenship test, including the language test.
You can find further information, including links to the application form and payment of fees, on the Ministry of Immigration and Integration's website.
The application process is described here.
Applications for automatic acquisition of Danish citizenship must be submitted directly to the Ministry of Immigration and Integration via Digital Post. Contact information can be found in the application form. The embassy recommends that applicants keep the receipt for their application until a decision has been made in the case.
For applicants without a MitID, it may be advantageous to appoint a representative in Denmark who can submit your application via their MitID and then communicate with the UIM on your behalf.
