European Regulation in matters of international successions

This part concerns Article 18^[1]

Actions are related when there is such a close connection between them that it is preferable to hear and judge them at the same time to avoid irreconcilable decisions.

When related actions are presented to courts in different States, the court seised second may stay its proceedings (but is not obliged to).

If the related actions are presented to courts of the first instance, the court seised second may decline jurisdiction at the request of a party, if the court seised first has jurisdiction to hear the requests and its law permits their consolidation.
