Norway Civil Registration
There was no separation of church and state in Norway before 21 May 2012, Up to this time there was no separation of church and state.
There was not a legally reqognized dissenter church in Norway until 1845. The law simply did not allow anyone to dissent from the Lutheran Church. After dissenter churches were accepterd in 1845, these congratations still had to report births and deaths to the local parish priest of the Lutheran Church within one month of these event. Sometimes we find that children of dissenters were not recorded as the law stated. Often a pastor would make this a very difficult visit, tryingto persuade or even threaten people to "come back" to the LUtheran Church. It dissenters lived in a city whre they could avoid being know by the church personnel, they sometimes didnot comply with this law.
A ne act in 1891 gave some dissenter groups permission to solemnize marriages, and from this time until 1919, the different groups were required to report births, deaths and marriages to the local Lutheran Church one a year. After 1919 they had to report to the local folkeregister (vital statistic office).
The law did not require a dissenter church to deposit their records in the state archives unless a congragation was dissolved. The percentage in 1875 was 0.4%, and in 1950 it was 3.76%.
You will find some of these recorded in Digitalarkivet (The Digital Archives) of Norway. See. link to civil records: http://www.arkivverket.no/URN:kb_read?idx_fylke=0&idx_kilde=VIBO&idx_periode=&idx_textsearch=&js=j
