The new commentary on the German Mediation Act by Roland Fritz and Dietrich Pielsticker (published by Luchterhand, Dec. 2012) covers collaborative law on pp. 797-810 (German language). It vividly explains the process, its applications, and the role of lawyers in collaborative negotiations. As pointed out under marginal note 1, the denomination of collaborative law in the German language area is still quite heterogeneous; further trends are to be closely monitored.
