Best Italian Inheritance Guide for US and UK Citizens
If you're a US or UK citizen who just inherited assets in Italy, here's what matters most: the Italian legal system will apply Italian inheritance rules to any Italian real estate regardless of what the will says, you'll owe Italian inheritance tax on the Italian assets with limited treaty relief, and your home country's embassy can help with exactly two things — death registration and a list of local lawyers. Everything else is on you.
The best guide for your situation is one that addresses the specific conflicts between your home country's legal system and Italy's — not a general Italian inheritance primer, and not a guide written for Italian residents.
What US and UK Citizens Face That Other Heirs Don't
The Forced Heirship Collision
US and UK law both operate on testamentary freedom — you can leave your assets to whoever you want. Italy doesn't. Italian law reserves mandatory shares (legittima) for the spouse, civil partner, and children, regardless of the will.
The 2025 Italian Supreme Court Decision 1632/2025 confirmed that forced heirship is a matter of Italian public policy (ordine pubblico). This means a US or UK will that leaves Italian real estate entirely to one child — disinheriting others — will be overridden by Italian courts for the Italian property.
This is the single most common shock for American and British heirs. A will that's perfectly valid in New York or London becomes partially unenforceable the moment Italian real estate enters the picture.
Brussels IV Doesn't Apply (For Americans)
EU Regulation 650/2012 (Brussels IV) allows EU residents to choose their home country's inheritance law to govern their entire estate. A German citizen living in Italy can elect German law and bypass Italian forced heirship.
But the US and UK occupy different positions:
- UK citizens: the UK opted out of Brussels IV entirely. UK nationals who lived in Italy are subject to Italian inheritance law by default. There's no choice-of-law election available through Brussels IV (though some Italian legal scholars argue that the Rome Convention principles still apply — this is contested territory).
- US citizens: the US isn't an EU member, so Brussels IV doesn't apply at all. However, Italian private international law may recognize a US choice-of-law clause in a will for movable assets. For real estate, Italian law applies regardless.
The practical result: for Italian real estate, both US and UK citizens are subject to Italian forced heirship rules. Period.
Different Tax Treaty Positions
Both the US and UK have tax treaties with Italy, but they work differently:
US citizens face a unique burden: the US taxes worldwide income regardless of residence. You'll owe Italian inheritance tax on the Italian assets AND may have US estate tax reporting obligations (though the US estate tax exemption of $13.61 million means most estates don't owe US tax). The US-Italy estate tax treaty provides a foreign tax credit — Italian inheritance tax paid reduces your US estate tax liability — but the compliance paperwork (IRS Form 706-CE) is an additional step US citizens must handle.
UK citizens have it slightly simpler. The UK-Italy double taxation agreement on estates provides that Italian assets are taxed in Italy and UK assets in the UK. UK Inheritance Tax (IHT) applies to worldwide assets of UK-domiciled individuals, but Italian tax paid gets credited against UK IHT on the same assets. UK heirs report through HMRC Form IHT400.
| Factor | US Citizens | UK Citizens |
|---|---|---|
| Italian inheritance tax | Yes, on Italian assets | Yes, on Italian assets |
| Home country estate tax | Yes (worldwide), but high exemption ($13.61M) | Yes (worldwide for UK-domiciled), £325K nil-rate band |
| Double taxation relief | Foreign tax credit (IRS Form 706-CE) | Credit method (HMRC Form IHT400) |
| Brussels IV election | Not available (non-EU) | Not available (UK opted out) |
| Forced heirship on Italian property | Applies, cannot override | Applies, cannot override |
Consular Support Differences
The US Embassy in Rome and the UK Foreign, Commonwealth & Development Office (FCDO) provide different levels of support:
US Embassy/Consulate: issues a Consular Report of Death Abroad (CRODA), which you'll need for US administrative purposes. They maintain a list of English-speaking lawyers and translators. They cannot provide legal advice, file Italian paperwork, or intervene with Italian authorities. The CRODA replaces a US death certificate for Social Security, insurance, and banking purposes back home.
UK FCDO: provides a more structured response. They issue a consular death registration (which can be used for UK administrative purposes), can help contact a local English-speaking funeral director, and maintain a more detailed referral network. Like the US consulate, they cannot file Italian succession paperwork or provide legal advice.
Neither embassy will help you navigate the Italian succession process itself. That gap — between what your embassy provides and what you actually need — is where most US and UK citizens discover they're on their own.
What the Best Guide for US/UK Citizens Must Include
A generic Italian inheritance guide misses the specific pain points for American and British heirs. Here's what to look for:
Forced heirship impact analysis by family structure — not just the rules, but specific scenarios: "What happens when a US will leaves the Italian apartment to a trust?" or "What if the UK will gives everything to the surviving spouse and excludes the children?"
Tax treaty navigation — how Italian inheritance tax interacts with US estate tax or UK IHT, including which forms to file in which country and in what order
Consular procedures for your nationality — CRODA process for Americans, consular death registration for Brits, and the practical timelines for each
Power of attorney that works across both systems — an Italian procura speciale that's valid in Italy AND recognized by your US/UK bank for estate administration back home
Timeline adjusted for transatlantic logistics — apostille processing times for US states (varies dramatically by state), UK apostille through the FCDO Legalisation Office (currently 2-4 weeks), and international document shipping times
The Mistakes US and UK Citizens Make Most Often
Assuming the will controls everything. It doesn't. The Italian property follows Italian forced heirship rules. Americans and Brits who've paid estate planning lawyers to draft ironclad wills discover those wills are partially unenforceable for Italian assets.
Not filing in both countries. Italian inheritance tax filing doesn't satisfy your US or UK reporting obligations, and vice versa. You need to file in both jurisdictions — Italy within 12 months, US/UK within your home country's deadline (9 months for US estate tax return, varies for UK IHT).
Trying to sell Italian property before completing succession. You cannot sell Italian real estate until the succession declaration is filed and the voltura catastale (property title transfer) is complete. American heirs who want to "just sell the apartment and be done with it" discover the sale is legally impossible until the 3-6 month succession process concludes.
Withdrawing from Italian accounts before notifying the bank. This is a criminal offense under Italian law. US and UK heirs accustomed to joint account access discover that Italian banks freeze everything upon death notification, and unauthorized pre-notification withdrawals can result in criminal prosecution AND count as formal acceptance of the inheritance (including any debts).

Frequently Asked Questions
Does Italian forced heirship apply if the deceased was an American living in the US who owned Italian property?
Yes. Italian forced heirship applies to Italian real estate regardless of the deceased's nationality or residence. A US citizen who never lived in Italy but owned a vacation home in Tuscany has that property subject to Italian legittima rules. The US will controls the US assets; Italian law controls the Italian property.
Do I need to pay inheritance tax in both Italy and the US/UK?
You'll owe Italian inheritance tax on the Italian assets. Whether you owe US estate tax or UK IHT depends on the total estate value relative to your country's exemption threshold. If you owe in both, the tax treaty provides a credit — you don't pay double tax on the same assets, but you do need to file in both countries.
Can I renounce just the Italian inheritance and keep assets in my home country?
Yes. Italian renunciation (rinuncia all'eredità) applies specifically to the Italian estate. You can renounce in Italy (avoiding any Italian debts) while accepting the inheritance under your home country's law for non-Italian assets. This requires separate filings in each jurisdiction.
How long does the process take for a US or UK citizen?
For a straightforward estate with cooperating heirs: 4-8 months from death to completed property transfer. Add 2-6 weeks at the start for codice fiscale issuance through the Italian consulate and power of attorney preparation. The 12-month succession declaration deadline is the hard constraint — most US/UK heirs complete the process in 6-9 months.
Should I hire an Italian lawyer or a US/UK lawyer who handles Italian cases?
For the Italian succession itself, you need Italian legal expertise — either an Italian lawyer or a US/UK firm with an Italian law practice (several exist in New York and London). A US or UK estate attorney handles the home-country filings (IRS Form 706-CE, HMRC IHT400). Some heirs use both; others handle the Italian side with a guide and local accountant, reserving the lawyer for the home-country tax compliance.
What if the deceased had a trust that holds Italian property?
This is one of the most complex scenarios. Italy doesn't have a domestic trust framework (though it recognizes foreign trusts under the Hague Trust Convention, ratified in 1989). Italian courts have increasingly scrutinized trusts that appear designed to circumvent forced heirship, especially after the 2025 Supreme Court decisions. If a trust holds Italian real estate, you likely need specialized legal advice — this is not a DIY situation.
