The convention enters into force on 1 September 2023, 1 year after the first 2 states had deposited their instruments of ratification/accession. If a party objects to the ratification or accession of another party, the convention will not enter into force between those parties. Also regional economic integration organizations (such as the European Union) can become a party if such an organisation governs recognition of judgments.
