Lagarök traces its origins to 1982 when Tryggvi Agnarsson opened his law firm in Reykjavík.
In 2009, Sævar Þór Jónsson, Tryggvi Agnarsson, Ágúst Ólafsson and Gísli Kr. Björnsson decided to pool their resources and form the Lagarök Law Firm. The firm was further strengthened in 2012 when Hlynur Ingason and Ingólfur Magnusson joined the team.
The Lagarök Law Firm has grown rapidly in recent years and is now able to offer even better services in numerous legal fields.
