Adverse possession
Description

In Denmark, the concept was first mentioned as "Hævd" in Jyske Lov in 1241, though only regulating between peasants and the church, with an asymmetric time limit of 30 years for the church, and 40 years for the peasant. In 1475, the 40 year limit was ruled to apply between farmers as well. In 1547 (after the Reformation) a rule was passed to change this to 20 years for everyone. The rule was later adopted into the Danish Code, published in 1683, this specific part still being in force today. The Norwegian Code from 1688, also contains a similar provision.
