This paper deals with the participation of common law countries in the work of the intergovernmental organization - The Hague Conference on Private International Law. The most significant discussed item of the United States involvement in the Hague Conference was the submission of the method of uniform legislation, in addition to the method of drafting of multilateral conventions. The federalism of the United States, Canada and Australia has left a strong influence on the text of Hague Conventions. It is difficult for these federal countries to complete the process of ratification of such conventions. Generally, it is clear that in common law countries the particular types of conventions have proved more successful than other conventions. The most popular are 'procedural conventions'. The second part of this paper is focused on 'procedural conventions': the Service and Evidence Conventions and those seeking to abolish legalization for foreign public documents.
