Cross-Border Inheritance in Italy: US & UK Wills, Forced Heirship and Succession Law
Italian inheritance law for US and UK citizens is one of the most misunderstood areas of international estate planning. If you own property in Italy, Italian succession rules apply to those assets — regardless of where you live, what nationality you hold, or what your home-country will says. Without proactive planning, forced heirs can challenge any disposition of your Italian estate, even years after your death.
Italian inheritance law imposes forced heirship (legittima) on all Italian-situated property, regardless of nationality. Under EU Regulation 650/2012, US and UK citizens can elect their home-country law by filing a notarial declaration of choice of law before an Italian notary before death.
📋 Key Takeaways
- Italian law applies to all property located in Italy, including real estate owned by foreigners
- Forced heirship (legittima) reserves a mandatory share for spouses and children — it cannot be removed by will alone
- EU Reg. 650/2012 allows US & UK nationals to elect their national law — but only via formal notarial declaration
- A foreign will is valid in Italy if apostilled and translated, but does not override legittima without a law election
- Italian inheritance tax starts at 4%, with a €1M exemption per heir for direct descendants
- The Dichiarazione di Successione must be filed within 12 months of death — no exceptions
What Is Italian Forced Heirship (Legittima)?
Forced heirship — known in Italian law as legittima — is a constitutional principle embedded in the Italian Civil Code (Articles 536–564). It reserves a non-waivable portion of any estate for specific categories of heirs, regardless of the deceased’s wishes or nationality.
For US and UK citizens, this is the single biggest planning risk. A perfectly valid US revocable trust or UK will does not automatically override Italian legittima on Italian-sited assets. Without proactive structuring, forced heirs can challenge any disposition that violates their reserved quota.
Who Are the Forced Heirs Under Italian Law?
- Spouse — always a forced heir, regardless of separation or property regime
- Children (including legally recognised non-marital children)
- Ascendants (parents / grandparents) — only when there are no children
Reserved Share: How Much Is Locked?
| Heirs Surviving | Reserved Quota | Freely Disposable |
|---|---|---|
| Spouse only | 1/2 of estate | 1/2 |
| 1 child (no spouse) | 1/2 of estate | 1/2 |
| 2+ children (no spouse) | 2/3 of estate | 1/3 |
| Spouse + 1 child | 1/4 + 1/4 = 1/2 | 1/2 |
| Spouse + 2+ children | 1/4 + 1/3 = 7/12 | 5/12 |
| Parents only (no children) | 1/3 of estate | 2/3 |
EU Succession Regulation 650/2012: Your Strategic Tool
The EU Succession Regulation (Brussels IV) came into force on 17 August 2015 and applies in all EU member states including Italy. It allows any person — including US and UK nationals — to elect the law of their nationality to govern the succession of their entire estate.
A valid professio iuris (choice of law declaration) made before an Italian notary effectively sidesteps forced heirship, provided it is correctly executed and registered. This is the most powerful instrument available to American and British property owners in Italy.
Requirements for a Valid Choice of Law
- Made expressly — implied elections are not accepted
- Contained in a testamentary disposition or a separate notarial act
- Executed before an Italian notary
- Filed and registered with Italian notarial authorities
- Compliant with formal requirements of both Italy and the elected legal system
Timing: Before Death, Not After
The election must be made while the testator is alive and legally competent. Heirs cannot make a retroactive choice of law after death. This makes early legal planning — ideally at the time of purchasing Italian property — essential for US and UK investors.
Does a US or UK Will Cover Italian Property?
A foreign will is partially valid in Italy, but it cannot override Italian forced heirship rules without a law election. Understanding this nuance is critical for anyone relying solely on a common-law will to cover Italian real estate.
Formal Validity of Wills Drafted Abroad
Italy recognises foreign wills under the Hague Convention (1961) and Law 218/1995. A US or UK will is formally valid in Italy if it:
- Was validly executed under the law of the country where it was drafted
- Does not violate Italian ordre public (public policy)
- Is accompanied by an official Apostille under the Hague Convention
- Has been translated into Italian by a certified sworn translator
Apostille, Translation & Publication: The 4 Steps
US wills: Secretary of State of the state where the will was notarised. UK wills: Foreign, Commonwealth & Development Office (FCDO).
Certified translator, sworn (asseverata) before an Italian court or consulate. Machine translations are rejected.
Foreign and holographic wills must be “published” (resa pubblica) before an Italian notary before producing legal effects on Italian property.
The notary registers the succession with the Agenzia delle Entrate. The Dichiarazione di Successione must follow within 12 months of death.
The Italian Succession Process: Timelines & Costs
There is no formal probate in Italy equivalent to US or UK court-supervised probate. Succession operates through a notarial declaration and tax filing system.
Declaration of Succession (Dichiarazione di Successione)
Mandatory tax filing submitted to the Agenzia delle Entrate within 12 months of the date of death. It inventories all Italian-sited assets and calculates the inheritance tax due. Late filing triggers penalties of 120%–240% of the tax due.
Italian Inheritance Tax Rates (2026)
| Relationship to Deceased | Tax Rate | Tax-Free Threshold |
|---|---|---|
| Spouse / direct descendants & ascendants | 4% | €1,000,000 per heir |
| Siblings | 6% | €100,000 per heir |
| Other relatives (up to 4th degree) | 6% | No threshold |
| All others (incl. unmarried partners) | 8% | No threshold |
| Disabled heirs | 4% | €1,500,000 per heir |
Transfer of Title After Succession
Once the declaration is filed, heirs must execute a trascrizione (land registry transcription) via a notarial deed. Costs: notary fees (€1,500–€3,500), cadastral tax (1%), mortgage tax (2%) — with exemptions for the primary residence.

| Choice of Law Election | N/A domestically | N/A domestically | Available under EU Reg. 650/2012 |
