The European Certificate of Succession: one proof, all member states
By Covered Abroad Research Desk · Last verified July 2026
What it is and what it does
The regulation that governs whose law applies to a cross-border estate also created the paperwork to match: the European Certificate of Succession, issued in the member state whose authorities handle the succession, producing the effects listed in Article 69 in other member states — and, once issued for use abroad, in the issuing state too. The design goal in the recitals: simplifying life for heirs and legatees habitually resident in a member state other than that in which the succession is being dealt with.

Optional by design — with one asymmetry
Article 62's own words: the use of the Certificate shall not be mandatory — entitled persons are under no obligation to apply for one and remain free to use the regulation's other instruments (decisions, authentic instruments, court settlements). The recitals add the asymmetry that gives the ECS its force: while nobody must obtain one, no authority or person presented with a Certificate issued in another Member State should be entitled to demand the alternative documents instead. Optional to hold; binding once shown.

Article 62(3): the Certificate shall not take the place of internal documents used for similar purposes in the Member States — a German Erbschein or Spanish notarial declaration keeps its domestic role; the ECS is the cross-border overlay. The practical case for it: estates with assets in two or more member states, where one Certificate spares heirs a parallel proof procedure per country. As with everything on our succession pages: descriptive only — the apply-or-not call belongs with a succession lawyer in the handling state.
