European Certificate of Succession: How to Prove Heirship Across EU Borders

What the European Certificate of Succession Does

If you inherit property or bank accounts across EU borders, the European Certificate of Succession (ECS) is the single most useful document you can obtain. It serves as standardized proof — recognized automatically in every participating EU member state — that you are a legitimate heir, legatee, or administrator of the estate.

Present an ECS to a bank in Germany, a land registry in Spain, or an insurance company in Italy, and they must accept it without requiring additional apostilles, court certifications, or local verification proceedings. No other document crosses EU borders this cleanly.

The ECS was introduced under the EU Succession Regulation No. 650/2012 — commonly called Brussels IV — which has governed cross-border successions in the EU since August 17, 2015.

Who Can Apply

An ECS can be requested by:

• Heirs who need to prove their inheritance rights in another EU country
• Legatees (recipients of specific bequests under a will)
• Executors or administrators who need to demonstrate their authority to manage estate assets abroad

The application goes to the competent authority in the EU member state that has jurisdiction over the succession — typically the court or notary in the country where the deceased had their last habitual residence.

How to Get One

The process follows a standard EU form (Annex 5 of the Regulation), available through the European e-Justice Portal:

Step 1: Identify the competent authority. This is determined by the deceased's last habitual residence, not nationality. If a British national died while living in France, the French notary handling the succession is the competent authority.

Step 2: Gather required documents. You will typically need:

• A certified death certificate
• The original or certified copy of the will (if one exists)
• Proof of your identity and your relationship to the deceased
• Evidence of the deceased's habitual residence
• Information about the estate assets in other EU countries

Step 3: Submit the application. The competent authority verifies the information, consults registers of wills if applicable, and issues the certificate. Processing times vary by country — from a few weeks in some jurisdictions to several months in others.

Step 4: Receive certified copies. The original ECS stays with the issuing authority. You receive certified copies, each valid for 6 months from the date of issue. You can request additional copies as needed.

Where It Works and Where It Does Not

The ECS is recognized in all EU member states except Denmark and Ireland, which opted out of the Brussels IV regulation entirely. In these countries, you will need separate documentation — typically a local grant of probate or equivalent.

The ECS also does not apply to:

• Non-EU countries. The UK (post-Brexit), Switzerland, Norway, and any other non-EU state do not participate. For assets in these countries, you need apostilled court documents or separate local proceedings.
• Successions opened before August 17, 2015. The regulation applies only to deaths on or after this date.
• Tax matters. The ECS proves heirship and administrative authority, but it does not resolve inheritance tax obligations. Each country applies its own tax rules independently.

The Brussels IV Framework

The ECS exists within the broader Brussels IV regulation, which harmonized succession law across the EU in two fundamental ways:

Default rule: habitual residence. The law of the deceased's last habitual residence governs the entire succession — all assets, movable and immovable, worldwide. If an American retires to Spain and dies there, Spanish succession law (including forced heirship) applies to their worldwide estate unless they opted out.

Nationality election (Article 22). A testator can choose in their will for the law of their nationality to govern the succession instead. An American living in Germany can elect US law, preserving testamentary freedom over assets that would otherwise be subject to German forced heirship. But this election must be explicit and made in the will — it does not happen automatically.

The nationality election affects succession law, not tax. Even with a US law election, German inheritance tax still applies to assets located in Germany.

Practical Advantages Over Traditional Authentication

Without the ECS, an executor dealing with assets in multiple EU countries would need to:

1. Get court documents apostilled in the country of origin
2. Have each document translated by a sworn translator in the destination country
3. Present the authenticated and translated documents to each bank, land registry, and insurance company individually
4. Potentially face local challenges to the validity of foreign court orders

The ECS eliminates all of this. One document, issued once, accepted everywhere in the EU (except Denmark and Ireland). No apostille needed, no translation required (though a practical translation may be helpful for institutional staff who do not read the language of issue).

For estates spanning three or four EU countries, the ECS can save weeks of processing time and thousands in authentication and translation costs.

Limitations to Know

Six-month validity. Certified copies of the ECS expire after 6 months. If the estate settlement stretches longer — and cross-border estates often do — you will need to request fresh copies.

Not a replacement for local proceedings. The ECS proves your rights and authority, but it does not handle the actual transfer of property. Registering a property transfer, closing a bank account, or filing an inheritance tax return still follows each country's local procedures.

National overrides. Despite Brussels IV's harmonizing intent, France and Germany have enacted national laws that can override the regulation's choice-of-law provisions in certain cases, particularly around forced heirship protections for children.

If your estate crosses both EU and non-EU borders, the International Estate toolkit covers both the ECS pathway for EU assets and the traditional apostille/legalization process for everything else — so you use the fastest available route in each jurisdiction.
