Part two will then examine and analyze authentic instruments under specific European Union private international law Regulations, focusing on the different cross-border legal effects allowed and procedures that apply to each such Regulation. u003cbru003e u003cbru003e Rigorous, authoritative and comprehensive, this will be an invaluable tool to all practitioners in the field.
