Getting married in Denamrk

I decided to get married in Denmark because of the complications involved in getting married in India. I followed the following procedure

• Filled in the application form online as per https://www.youtube.com/watch?v=gY65BffVNxc&t=1009s. The video was very helpful. Some specific details I found helpful from other reddit posts
• As proof of relationship, we used airbnb booking, whatsapp/instragram screenshots for every month, flight tickets, picture of us together. (It was almost 20 pages).
• At first we struggled with the passport scan, as the pages shouldn't be crooked/corners should be visible etc. We managed to get a good version with our scanner. But the Family Law Agency rejected it and asked us to provide additional, higher quality images. So I used my Iphone, took several pictures, at least 5 per page, and sent this large document (over 150 Mb). They finally agreed.
• In the You Tube link you would find a link to the Copenhagen wedding hall booking site. We wanted to see if it would fit into our schedule. Unfortunately it was quite busy, so we decided to go for Aabenraa Kommune.
• It took us 1 week to get the first answer. Then, when we sent the additional documents, we got a confirmation in 15 days. It was before Christmas, so we were a bit worried that they would go on holiday and not reply. But luckily we got a response before that.
• In Aabenraa it is so easy to find an appointment in 4 weeks. We were actually too early, so now we are waiting for the appointment to open, as new appointments are released 8 weeks in advance.
• I would suggest to follow the rest of the information from video or other sources. This was my experience so take it with a pinch of salt. Fyi, we both are from India and I have Niederlassungserlaubnis in Deutshcland and my girl friend has a Schengen Visum.
