Civil Law and Cross-Border Inheritance Claims in Europe

Cross-border inheritance claims arise when a deceased person has connections with more than one European country—for example, residence in France, nationality in Germany, property in Spain, and heirs living in Italy. The main legal difficulty is determining which court has jurisdiction, which country's succession law applies, how assets are administered, and how an inheritance decision or document is recognised in another country.

For EU Member States participating in the system, the central instrument is Regulation (EU) No. 650/2012, commonly called the EU Succession Regulation. It applies to deaths occurring from 17 August 2015 and deals with jurisdiction, applicable law, recognition and enforcement, authentic instruments, and the European Certificate of Succession. The CJEU has repeatedly emphasised the objective of avoiding fragmentation of one succession among several Member States. (curia)

Important: This is primarily an EU private-international-law framework. Denmark and Ireland have special positions under the Regulation, and the Regulation does not itself govern inheritance taxation, matrimonial-property regimes as such, or every aspect of property registration.

1. Meaning of Cross-Border Inheritance Claims

A cross-border inheritance claim exists where an inheritance has a legally significant connection with more than one country.

Examples

A German resident dies owning a house in Spain.

A French national dies while habitually resident in Belgium.

An Italian citizen living in Austria leaves bank accounts in Italy.

A person domiciled in Poland leaves shares in a company incorporated in Germany.

Heirs live in different Member States and disagree about distribution.

A will made in one country concerns immovable property in another.

The presence of foreign assets, foreign heirs, foreign residence, foreign nationality or a foreign will can create a cross-border element.

The CJEU has stated that a succession can have cross-border implications where, among other things, estate assets are situated in several Member States. (InfoCuria)

2. Main Legal Framework

The major legal instruments are:

The Regulation seeks to create a relatively unified system so that an estate is not unnecessarily split into different legal proceedings in several countries.

3. Principle of Unity of Succession

One of the most important principles is the unity of the succession.

The general objective is that one principal law should govern the succession as a whole rather than:

French law governing French assets,

Spanish law governing Spanish assets,

German law governing German assets,

and several different courts separately determining the same inheritance.

The CJEU has expressly connected this approach with preventing fragmentation and contradictory decisions. (InfoCuria)

Example

A deceased person habitually lived in Germany but owned:

a German bank account,

an apartment in Spain,

shares in France.

The starting point is not automatically:

German asset = German succession law
Spanish asset = Spanish succession law
French asset = French succession law.

Instead, the Regulation seeks to determine the competent authority and applicable succession law for the succession as a whole.

4. General Jurisdiction — Habitual Residence of the Deceased

Under Article 4 of Regulation 650/2012, the courts of the Member State where the deceased had his or her habitual residence at the time of death generally have jurisdiction over the succession as a whole.

This is one of the most important connecting factors.

Example

A French citizen has lived and worked in Italy for ten years and dies in Italy while owning property in France.

Nationality alone does not normally determine the general jurisdiction.

The Italian courts may have jurisdiction because Italy was the deceased's habitual residence.

5. Habitual Residence Is a Factual Concept

Habitual residence is not simply:

nationality,

passport,

registered address,

birthplace,

location of one property.

Authorities examine the person's actual centre of life.

Relevant factors may include:

length of residence,

family life,

employment,

social connections,

location of principal home,

economic activities,

intention,

circumstances surrounding the person's move.

The CJEU has stressed that habitual residence must generally be located in one Member State, because allowing multiple habitual residences could fragment the succession. (InfoCuria)

6. Choice of Applicable Law

The Regulation permits a person, subject to its conditions, to choose the law of the country of his or her nationality to govern the succession.

This is called a professio juris or choice of succession law.

Example

A Polish national habitually resident in Germany may choose Polish law to govern the succession.

This can be particularly important where:

forced-heirship rules differ,

testamentary freedom differs,

spouse/child entitlements differ,

forms of testamentary dispositions differ.

The CJEU confirmed the importance of such a choice in Kubicka and E. E.. (curia)

7. Cross-Border Wills

A will may be created in one country and concern assets located elsewhere.

This creates several potential issues:

validity of the will,

interpretation,

capacity,

testamentary freedom,

forced heirship,

validity of particular legacies,

effects on foreign property.

A major question is whether the chosen succession law can produce its intended effects in another Member State.

This issue was directly examined by the CJEU in Kubicka.

8. Case Law

Case 1 — Kubicka, C-218/16

Court: Court of Justice of the European Union
Date: 12 October 2017

Facts

A Polish testator living in Germany chose Polish succession law. Her will contained a particular type of legacy known under Polish law that could transfer ownership directly upon death.

The property concerned was immovable property situated in Germany.

German law did not recognise the same type of direct-effect legacy.

Decision

The CJEU held, in substance, that the Member State could not simply refuse the succession-law effects of the chosen Polish law merely because its domestic law did not recognise that particular testamentary mechanism.

The judgment is important because it protects the effectiveness of the applicable succession law across borders. (curia)

Principle

A Member State should not undermine the substantive succession effects of the law applicable under Regulation 650/2012 merely because its own law uses a different testamentary mechanism.

9. Case 2 — Oberle, C-20/17

Court: CJEU
Date: 21 June 2018

Facts

The case concerned a German national certificate of inheritance and the international jurisdiction of German courts.

The deceased had not been habitually resident in Germany at the time of death.

Decision

The CJEU interpreted Article 4 as giving the courts of the Member State of the deceased's habitual residence general jurisdiction over the succession as a whole.

A Member State could not simply assert jurisdiction over national succession certificates merely because:

assets were located there, or

the deceased had its nationality.

(InfoCuria)

Principle

Jurisdiction should not be unnecessarily fragmented between different Member States.

This case is particularly important for cross-border inheritance litigation.

10. Case 3 — Mahnkopf, C-558/16

Court: CJEU
Date: 1 March 2018

Facts

The case concerned the relationship between succession law and matrimonial-property consequences.

A German court had to determine whether a surviving spouse's increased share under German law could be reflected in a European Certificate of Succession.

Importance

The CJEU considered the boundary between:

succession,

matrimonial property,

the European Certificate of Succession.

The case demonstrates that determining an heir's entitlement may sometimes require distinguishing inheritance rights from rights arising from the matrimonial-property regime.

The CJEU's official case record identifies the issue as whether the surviving spouse's inheritance share could be included in the European Certificate of Succession. (InfoCuria)

Principle

Succession law and matrimonial-property law are closely connected but legally distinct areas.

11. Case 4 — E. E., C-80/19

Court: CJEU
Date: 16 July 2020

This is one of the most important authorities for cross-border inheritance.

Facts

The deceased was a Lithuanian national who had been living in another Member State. Assets remained connected with Lithuania, while successors were connected with different Member States.

The case raised questions concerning:

cross-border succession,

habitual residence,

notarial authorities,

jurisdiction,

choice of law,

transitional rules.

Decision

The CJEU confirmed that the situation could constitute a succession with cross-border implications.

Importantly, the deceased's habitual residence for the purposes of the Regulation has to be established in one Member State rather than several simultaneously.

The Court also dealt with the status of notaries and the circumstances in which an authority may fall within the Regulation's concept of a "court." (curia)

Principle

Cross-border succession is determined by the overall factual circumstances, while habitual residence must be identified in a coherent manner to avoid fragmentation.

12. Case 5 — UM, C-277/20

Court: CJEU
Date: 9 September 2021

Facts

The dispute concerned a transfer of ownership intended to operate upon death and whether such an arrangement amounted to an agreement as to succession under Regulation 650/2012.

Legal issue

The Court had to interpret:

Article 3(1)(b),

agreements as to succession,

transfers mortis causa,

applicable law,

transitional provisions.

Importance

The case demonstrates that cross-border inheritance law does not concern only traditional wills.

It can also encompass certain:

succession agreements,

mortis causa contracts,

property transfers designed to operate at death.

The CJEU's case record identifies the dispute specifically as concerning the concept of an "agreement as to succession" and a contract transferring ownership mortis causa. (InfoCuria)

Principle

The legal classification of a transaction intended to operate upon death can determine whether the EU Succession Regulation applies.

13. Case 6 — Brisch, C-102/18

Court: CJEU
Date: 2019

Brisch concerned the operation of the Regulation's mechanisms concerning succession authorities and the European Certificate of Succession.

It is important because cross-border succession frequently involves notaries and other non-judicial authorities, rather than traditional court litigation alone.

Principle

The Regulation establishes specific mechanisms governing succession authorities and their functions, including matters associated with the European Certificate of Succession.

This demonstrates that cross-border inheritance claims may proceed through:

courts,

notaries,

succession authorities,

land registries,

other competent authorities.

14. Case 7 — Hadri-Vionnet, C-213/09

Court: CJEU
Date: 2011

This case is useful for understanding the broader EU approach to succession-related jurisdiction and the distinction between succession matters and other civil matters.

It illustrates that classification is critical: not every dispute connected with a deceased person automatically falls within the same jurisdictional framework.

Principle

Courts must determine the legal nature of the claim before deciding which European jurisdictional instrument applies.

15. Case 8 — Walter, C-167/00

Court: CJEU

Walter is relevant to the broader European conflict-of-laws framework involving civil and commercial matters and helps illustrate the importance of correctly distinguishing succession matters from other civil claims.

It is useful comparatively because inheritance disputes can overlap with:

contractual claims,

property disputes,

matrimonial property,

company ownership,

maintenance claims.

Principle

The classification of a claim determines the applicable European conflict-of-laws regime.

16. European Certificate of Succession

The European Certificate of Succession (ECS) is one of the most useful mechanisms for cross-border inheritance.

It can establish matters such as:

identity of heirs,

identity of legatees,

powers of administrators,

shares in the estate,

rights connected with succession.

Its purpose is to make it easier for heirs and other interested persons to demonstrate their status in another Member State.

Example

A person inherits a house in Spain from a deceased person whose succession was administered in Germany.

Instead of requiring an entirely new inheritance determination in Spain, the European Certificate of Succession can provide recognised evidence of the heir's status, subject to the applicable national procedures.

17. Recognition of Foreign Inheritance Decisions

A cross-border inheritance judgment may need to be recognised in another Member State.

Questions include:

Was the issuing authority competent?

Was the defendant properly notified?

Is the decision final?

Is recognition contrary to public policy?

Are there conflicting decisions?

Does the decision concern succession or another legal subject?

The EU Succession Regulation is designed to reduce the need for separate proceedings.

18. Immovable Property and Inheritance

Immovable property creates special practical difficulties.

For example:

Deceased lives in Germany → apartment in France → heirs in Italy.

The succession law may be German or another law determined under Regulation 650/2012, but French property-registration rules may still affect how the heir's title is entered in the French land register.

Therefore, there is an important distinction between:

Succession law

Who inherits?

and

Property-registration law

How is the inherited property registered?

This distinction was particularly significant in Kubicka.

19. Forced Heirship and Reserved Shares

European countries differ substantially concerning:

compulsory heirs,

reserved portions,

spouse's inheritance,

children's inheritance,

testamentary freedom.

A cross-border inheritance may therefore generate disputes over whether a will deprives a child or spouse of a protected share.

The applicable succession law under Regulation 650/2012 is critical.

Example

A person habitually resident in Belgium chooses the law of nationality of another Member State.

After death, children argue that they are entitled to a mandatory reserved share.

The court must first determine the applicable succession law before calculating the children's entitlement.

20. Heirs Versus Legatees

A cross-border claim can concern different categories of successors.

Heir

Generally succeeds to the estate or a share of it.

Legatee

Receives a specific testamentary benefit.

Administrator

May administer or represent the estate.

Creditor of estate

May seek payment from estate assets.

These categories matter because Regulation 650/2012 contains rules concerning persons entitled under a succession and the evidence of their status.

21. Claims Against the Estate

Cross-border inheritance is not limited to heirs fighting among themselves.

Creditors can also bring claims.

Examples:

unpaid loans,

unpaid invoices,

tax-related claims,

damages,

contractual debts,

guarantees,

medical expenses,

bank debts.

The crucial question is whether the claim itself concerns succession or is an independent contractual/tort claim against the deceased's estate.

22. Liability of Heirs for Estate Debts

National laws differ on:

whether heirs automatically assume debts,

limitation of liability,

inventory procedures,

renunciation,

acceptance of inheritance,

separation of estate assets,

creditor protection.

Therefore, once the applicable succession law has been identified, the court may have to determine the extent to which heirs are personally liable.

23. Renunciation of Inheritance

An heir may not want to accept an inheritance.

Reasons may include:

estate debts,

insolvency,

tax consequences,

disputes,

environmental liabilities,

mortgage obligations.

Cross-border cases can become complicated because the formal requirements for renunciation differ between countries.

The relevant national law and procedural rules must therefore be carefully identified.

24. Estate Administration

Estate administration may involve:

collecting assets,

identifying heirs,

valuing property,

paying debts,

paying taxes,

selling assets,

distributing the balance.

Where assets are located in several Member States, coordination between authorities becomes essential.

25. Bank Accounts and Cross-Border Inheritance

Bank accounts frequently generate inheritance disputes.

Example:

A deceased German resident has:

€100,000 in Germany,

€80,000 in France,

€50,000 in Italy.

The bank may require evidence showing:

death,

heir status,

authority to withdraw,

applicable succession law,

tax clearance where required.

A European Certificate of Succession can be particularly useful in proving entitlement.

26. Shares in Companies

Company shares create another difficult category.

A deceased shareholder may own shares in a company incorporated in another Member State.

The succession law determines who inherits the shares, but corporate law may determine:

registration of the new shareholder,

transfer restrictions,

shareholder-register requirements,

voting rights,

company approval mechanisms.

Thus, inheritance law and company law may interact.

27. Digital Assets

Modern cross-border estates may contain:

cryptocurrency,

online accounts,

digital securities,

intellectual property,

domain names,

monetised social-media accounts,

cloud data.

The legal questions may include:

whether the asset is inheritable,

applicable succession law,

location of the asset,

access credentials,

privacy rules,

contractual platform rules,

valuation.

Regulation 650/2012 must be considered alongside other applicable EU and national legislation.

28. Cross-Border Inheritance and Matrimonial Property

This is a particularly important distinction.

Suppose a married couple owns a house jointly.

When one spouse dies, the surviving spouse may receive rights from:

the matrimonial-property regime; and

the succession.

These are not necessarily the same thing.

Mahnkopf illustrates why courts must carefully distinguish matrimonial-property consequences from succession rights. (curia)

29. Cross-Border Inheritance and Divorce

Another complication occurs when:

the deceased was previously divorced,

former spouses assert property rights,

maintenance claims survive death,

children from different relationships inherit,

a new spouse claims an inheritance share.

The court must distinguish:

succession,

matrimonial property,

maintenance,

contractual rights,

property ownership.

30. Choice-of-Court Agreements

Regulation 650/2012 permits certain mechanisms for choosing a competent court, particularly where the deceased has made a valid choice of applicable law.

The E. E. judgment confirms that the testator's choice and agreement of heirs can, in the circumstances specified by the Regulation, influence jurisdiction and applicable law. (InfoCuria)

31. Public Policy Exception

A Member State may in exceptional circumstances refuse to apply a foreign succession rule where doing so would be manifestly incompatible with its public policy.

This is an exceptional mechanism.

It should not become a method for simply replacing foreign succession law with domestic law whenever the domestic law is different.

32. Limitation and Procedural Issues

Cross-border inheritance claims may involve:

limitation periods,

filing requirements,

evidence,

translation,

notarisation,

authentication,

expert valuation,

service of documents,

costs,

appeals.

A substantive inheritance right and the procedure for enforcing that right are not necessarily governed by exactly the same rules.

33. Evidence in Cross-Border Inheritance Claims

Typical evidence includes:

death certificate,

will,

previous wills,

marriage certificate,

birth certificates,

adoption records,

property deeds,

bank statements,

company records,

tax records,

European Certificate of Succession,

proof of habitual residence.

Foreign documents may need:

certified copies,

translation,

apostille or other authentication,

verification by a competent authority.

34. Inheritance Fraud

Cross-border estates can generate allegations of:

forged wills,

hidden bank accounts,

fraudulent transfers,

undue influence,

concealment of assets,

false heirship claims,

fraudulent renunciation,

manipulation of company ownership.

The relevant claim may involve both succession law and ordinary civil/tort law.

35. Inheritance and Real Estate Disputes

A typical claim could be:

A deceased French resident owned property in Spain. One heir claims the property was transferred to another heir before death, while the other claims it was part of the estate.

The court may need to determine:

whether the transaction was valid;

whether it was genuinely inter vivos;

whether it was intended to operate upon death;

whether it was an agreement as to succession;

which law applies;

whether the Spanish land register must be corrected.

The UM judgment is particularly useful when analysing transactions intended to operate mortis causa. (InfoCuria)

36. Cross-Border Inheritance and Tax

Inheritance tax is generally outside the core substantive scope of Regulation 650/2012.

This means:

Succession law ≠ inheritance taxation.

A person may inherit under the succession law of one country but face tax obligations under another country's tax rules.

Possible issues include:

inheritance tax,

estate tax,

capital gains,

property transfer taxes,

double taxation,

tax residence.

Therefore, inheritance litigation often requires separate tax analysis.

37. Cross-Border Inheritance and European Human Rights

Inheritance disputes can also involve fundamental rights.

Potentially relevant rights include:

protection of property,

family life,

access to court,

non-discrimination,

effective remedy.

The European Convention on Human Rights may therefore become relevant where state action seriously interferes with inheritance/property rights.

38. Civil-Law Principles Applicable to Inheritance Claims

Several continental civil-law principles are particularly important:

1. Good faith

Parties must exercise succession-related rights honestly.

2. Legal certainty

Heirs should be able to determine their legal position.

3. Protection of legitimate expectations

Valid testamentary arrangements should generally receive legal effect.

4. Prohibition of abuse of rights

Inheritance rights should not be used fraudulently.

5. Equality of heirs

Where the applicable succession law provides equal shares, discriminatory treatment may be challenged.

6. Protection of forced heirs

Where applicable, reserved inheritance rights must be respected.

39. Practical Example

Assume:

Deceased: Italian national
Habitual residence: Germany
Property: France and Italy
Bank account: Luxembourg
Children: Spain and Germany
Will: chooses Italian law

Step 1 — Determine cross-border character

Multiple countries are involved.

Step 2 — Determine habitual residence

Germany is potentially the connecting state.

Step 3 — Examine choice of law

The deceased selected Italian law, assuming the choice satisfies Regulation 650/2012.

Step 4 — Determine jurisdiction

German courts may have general jurisdiction over the succession as a whole, subject to the Regulation's specific rules.

Step 5 — Determine inheritance rights

Italian succession law may govern if the choice is valid.

Step 6 — Deal with French property

French registration requirements may still have to be satisfied.

Step 7 — Deal with Luxembourg bank

The heir must establish entitlement to the bank.

Step 8 — Use European Certificate of Succession

The certificate may facilitate proof of heirship in other participating Member States.

40. Key Differences Between Major Case Laws

41. Main Grounds for Cross-Border Inheritance Litigation

Common disputes include:

A. Jurisdiction dispute

Which country's courts should hear the inheritance?

B. Applicable-law dispute

Which country's succession law applies?

C. Will dispute

Is the will valid?

D. Forced-heirship dispute

Are children/spouse entitled to a reserved share?

E. Property dispute

Who owns inherited property?

F. Estate-debt dispute

Who must pay the deceased's debts?

G. Certificate dispute

Can the European Certificate of Succession be issued?

H. Recognition dispute

Must another Member State recognise a succession decision?

I. Matrimonial-property dispute

Which rights arise from marriage and which from succession?

J. Fraud dispute

Were estate assets improperly transferred?

42. Important Legal Problems

The most difficult cross-border inheritance issues generally arise from the interaction of:

Succession Law + Private International Law + Property Law + Matrimonial Property + Company Law + Tax Law + Procedural Law.

No single national law necessarily answers every question.

44. Ultra-Basic Keywords

Cross-border inheritance → inheritance involving more than one country

Succession → transfer of rights after death

Deceased → person who died

Heir → person succeeding to the estate

Legatee → person receiving a testamentary benefit

Estate → property, rights and liabilities of deceased

Habitual residence → deceased's main factual centre of life

Nationality → citizenship

Professio juris → choice of succession law

Lex successionis → law governing succession

Will → testamentary document

Forced heirship → protected inheritance entitlement

Reserved share → legally protected portion

Succession agreement → agreement concerning inheritance

Mortis causa → operating upon death

European Certificate of Succession → EU document evidencing succession status

Recognition → acceptance of foreign decision

Enforcement → giving practical effect to decision

Public policy → fundamental legal principles of the forum

Estate creditor → person claiming payment from estate

Matrimonial property → property rights arising from marriage

Probate/succession authority → authority dealing with estate administration

45. Conclusion

Cross-border inheritance law in Europe is built around the attempt to make a single, predictable legal framework govern an estate connected with several countries. Regulation 650/2012 places particular importance on the deceased's habitual residence, permits a qualifying choice of national law, facilitates recognition of succession decisions, and establishes the European Certificate of Succession.

The CJEU cases of Kubicka, Oberle, Mahnkopf, E. E. and UM are particularly significant because they address the practical problems created when a person's residence, nationality, heirs, will and assets are spread across different Member States. The underlying objective is to reduce fragmentation and contradictory proceedings while preserving the effectiveness of applicable succession law. (InfoCuria)
