You can find general info on writing to the Royals here. Along with some specifics on writing a letter of condolence here.
Who to write to:
Even though they are divorced I think it would be very appropriate to send a letter of condolence to Princess Märtha Louise and/or her daughters.
I could either address your letter/card to:
- HH Princess Märtha Louise
- & mention in your letter that you are sending your condolences to her and her daughters.
- Maud, Leah & Emma Behn
- The Family of Ari Behn
The Norway royals don't regularly reply. So, I really have no idea if they would reply or what it would look like.
Note: When referred to in English, Princess Märtha Louise is an HH (Her Highness), not an HRH (Her Royal Highness).

The Address:
Det Kongelige HoffWhen to write:
Det Kongelige Slott
Postboks 1 Vika

Don't feel like you need to write the minute you hear the news. Give yourself a few days to reflect, see what information is being released by the Palace, family, media, etc.
I think anytime within 2 weeks after the passing or shortly after the funeral is acceptable.
