The Hague Conference on Private International Law organized a meeting of an Experts Group to discuss the feasibility of a future instrument on the issues of parentage and surrogacy.  This group met from February 15-17, 2021 online.  You can view its report here.  The group concluded it is ready to prepare a final report to the Council on a possible future legal instrument that will outline private international law rules on parentage due to surrogacy.  But, the group concluded that it was difficult to have meaningful discussions virtually, so it will wait until 2022 so that members can travel to meet in-person to prepare a final report.  Therefore, the current goal is to prepare a final report to submit to the Council for its 2023 meeting (usually held in March each year).
