On 1 January 2025, new inheritance regulations in Swiss Private International Law (PIL) will come into force. The revision efforts are primarily triggered by the European Succession Regulation (EuErbVO), which came into force in 2015. Among other things, the regulation aims at simplifying estate planning and the settlement of estates in inheritance cases involving foreign countries. Switzerland's international inheritance law (in Chapter 6 of the PIL) will be modernized as part of the revision and adapted to legal developments abroad. On the one hand, the autonomy of the parties will be strengthened and, on the other hand, the risk of conflicts of jurisdiction with foreign authorities, particularly in the EU, will be reduced. The partial harmonization of Swiss international inheritance law with the EU Succession Regulation is intended to prevent conflicting decisions in relation to the member states of the EU Succession Regulation. This is to be achieved in particular by improving the coordination of decision-making powers on both sides by aligning the rules of jurisdiction and recognition as far as possible or, where this is not possible, by ensuring that both sides apply the same law.
