The European Certificate of Succession: when it helps — and when it doesn’t
The European Certificate of Succession (ECS) is a standard certificate, created by the EU Succession Regulation, proving who the heirs of an estate are — and it must be recognised in every participating EU country without any further formality. It shines when someone habitually resident in one EU country leaves assets in another: one certificate, issued once, opens doors in both. Its limits are just as important: the UK never joined the certificate system, so a UK estate cannot use it; it does not replace the local transfer machinery (registration and tax still run locally); and it is optional — the national documents always remain available. Knowing when to use it, and when not to bother, is the actual skill.
Ask what single instrument the EU Succession Regulation created beyond its choice-of-law rules, and this is it: the European Certificate of Succession — a standard-form certificate, the same in every participating member state, proving who the heirs, legatees, executors or administrators of an estate are and what their shares and powers are.
What makes it powerful
Recognition without formality. A certificate issued in one participating state must be accepted in all the others — no apostille, no re-proving the family tree to a second country’s authorities. For the right estate it collapses duplicated paperwork: prove the heirs once, use the proof everywhere the Regulation reaches.
The estate it was made for
Picture a Dutch couple retired to Spain, with a holiday flat in France and an account in the Netherlands. The succession is opened where they were habitually resident — Spain — and the Spanish authority can issue an ECS that the French registry and the Dutch bank must both accept as proof of heirship. One certificate, three countries, no re-litigation of who inherits. Estates like that — EU resident, assets in a second member state — are exactly where we reach for it.
Who issues it — and why that matters
Not the heirs, and not their lawyer directly: the certificate is issued by a competent authority — typically a notary or court — in the member state whose courts have jurisdiction over the succession, usually the state of habitual residence at death. Our role is to prepare the application and the evidence so the issuing authority can act quickly; certified copies of the certificate then carry a limited validity period, so the timing of copies is planned around when they will actually be used.
When it does NOT help — read this before asking for one
Three honest limits. First, it is rarely the tool for UK estates. Where the person lived in the UK, an EU country can issue a certificate only in limited cases — for example where they held that country’s nationality, or had lived there within the last five years — and the usual answer is each country’s own heirship document, run in parallel. That is the position for most of the British families we act for. Second, the certificate proves who inherits — it does not transfer anything. Land registration, the tax filings and the bank formalities still run under each country’s own machinery: the ECS is evidence for question one, never a substitute for question two. Third, it is optional — the national documents (habilitação, escritura, acte de notoriété, dichiarazione) always remain available, and for a single-country estate they are usually the faster, cheaper answer. An ECS earns its fee only when a second participating country is genuinely in play.
The practical rule of thumb
Deceased habitually resident in Portugal, Spain, Italy or France, with assets in a second EU country — ask us about an ECS; it may save the second country’s paperwork entirely. Deceased resident in the UK or Ireland with assets in our countries — the ECS is rarely the tool (Ireland, like the UK, stayed outside the Regulation), and the local instruments do the work, in parallel with the home estate. Either way the analysis of which law governs comes first — the certificate, where available, is the proof of the answer, not the answer itself.
