International and European family law is becoming increasingly important. This Commentary deals with the new European divorce law, namely: the Rome III Regulation on enhanced cooperation in the field of separation and divorce the Brussels IIa Regulation on the recognition and enforcement of judgments in matrimonial and custody matters (European Marriage Regulation) In addition to various other European standards and conventions, these two directly applicable Regulations are the central provisions of the new European divorce law and thus of paramount importance for every legal user in family law in all binational family law cases. The Commentary is supplemented by a brief explanation of the Hague Convention on Protection of Children.
