The man was also ordered to pay 275,000 kroner to the youngest daughter, who was just six years old when the sexual abuse began. The other girl, who was around nine when the abuse started, will receive 250,000 kroner in compensation, Østlands-Posten reported.
According to the court ruling, the abuse occurred in the family's residence in Larvik. The girls were abused over a long period, were not given enough food and were attacked sexually after their mother left for work in the mornings and before the girls had to go to school.
The school alerted authorities after the youngest girl repeatedly showed up with bruises on her body. Norway's Child Welfare Service (Barnevernet) were warned twice about the abuse and a crisis centre was involved in 2012 when the mother and her daughters sought help. The police and Barnevernet took action in autumn 2014.
The 48-year-old denied the sexual allegations in court and also claimed he never physically abused his daughters. The girls' mother initially supported their claims but in court changed her story and supported her husband's version of events.
The man was given two weeks to appeal against the verdict. The parents have lost custody of the two young girls.
