This input into the discussion elaborates on the theoretical understanding of expertise in socio-legal studies. It argues that conceptually socio-legal studies have a rather narrow view on the legal expert. This is due to the prevailing socio-legal conception of modern law as part of a differentiated society and building upon this, a role-theory
understanding of legal expertise. Against this background, the expertise of laypeople remain underestimated and thus, underconceptualised. In my paper, I therefore suggest the further theoretical integration laypersons in the law.
