If you wish to spread the ashes in any place other than a cemetary, you need permission from the Länsstyrelse (county administration) in the applicable county.
On applying for permission you need to enclose
- genealogy table from the IRS (släktutredning från Skatteverket)
- map of the area where you wish to spread the ashes, with the exact spot marked out
- permission from the land owner (not necessary for spreading at sea, lakes or northern mountains (fjäll))
If you wish to spread only a part of the ashes, you have to have compelling reasons (synnerliga skäl) to do so. One valid reason is that the rest of the ashes will be interred or spread in another country.
There is no custom of doing it without permission. Personally, I've never heard of such a thing - spreading the ashes after a dear departed in secret?! I don't think that is treating the remains with proper respect, not at all.
If permission is denied, it can be appealed. The law talks of suitable places and that, I think, generally means a quiet spot in the countryside. The county administration is mainly concerned that the ashes must be treated with proper respect and that the spreading poses no threat to general sanitation.
Many cemetaries have special areas where ashes can be spread or interred anonomously. These places are always very beautiful and one does not have to worry about upkeep or headstones etc. They are becoming increasingly popular.
The laws regulating burials, cremations and the spreading of ashes are Begravningslagen (1990:1144) and Begravningsförordningen (1990:1147).
