réttarbót (ON) noun

A legal amendment, such as those issued by the king of Norway. Often these were used to grant privileges or dispensations, but any type of change to an earlier law could be given in a réttarbót. One such example is Seyðabrævið, which grants special dispensation to Faroe Islanders in household and farming matters. These amendments were subject to approval of the assembly/-ies in which they were to take force. From the second half of the twelfth century, réttarbætr were increasingly used to issue new laws (ON nýmælir). Legislation of a similar nature was also passed under the names bréf (‘letter’) or skipan (‘ordinance’) during the thirteenth and fourteenth centuries. Both terms, along with réttarbót, could refer to royal ordinances or proclamations.

In several law codes (e.g. FrL and Jó) such amendments were transmitted in their own section as a kind of appendix to the law.
