The Odelsrett is an ancient Scandinavian allodial title which has survived in Norway as odelsrett and existed until recent times in Sweden as bördsrätt. The Norwegian law stipulates the right, when a farm is to be sold, of any member of the family, by the principle of primogeniture, to buy it, consistent with Åsetesrett. If the property is sold to a stranger, family members have the right within a specified period of time (which varies over history, but ten years can be considered typical of recent usage) to redeem it at the price paid, with the additional cost of the improvements.
