When a U.S. citizen inherits property, bank accounts, company interests or family assets in Italy, the succession rarely follows the same logic as a domestic estate proceeding in the United States. The case may involve Italian civil law, U.S. tax rules, foreign wills, translated documents, notarial formalities, cadastral registrations and, in many situations, family members living in different jurisdictions. What appears at first to be a simple inheritance can therefore become a complex legal process requiring a coordinated analysis of both systems.

For American heirs, the most important point is not only identifying what has been inherited, but understanding which law governs the succession, which authority has jurisdiction, which taxes may arise and which documents are required before the assets can be transferred or administered. A clear cross-border estate planning strategy can reduce delays, prevent disputes among heirs and protect the value of Italian assets, especially when real estate, family wealth or business interests are involved.

Italian inheritance law and the risks of applying U.S. assumptions

Italian inheritance law is rooted in the civil law tradition and differs substantially from the approach generally familiar to U.S. citizens. In many U.S. estate plans, the testator expects broad freedom to decide how assets will be distributed. In Italy, however, succession rules are shaped by the protection of certain family members, known as reserved heirs. This means that a spouse, children and, in some cases, ascendants may have legally protected rights to a portion of the estate, even when a will expresses a different distribution plan.

This concept, often described in English as forced heirship, is one of the main sources of misunderstanding in USA–Italy inheritance cases. A will prepared in the United States may be valid from a formal standpoint, but still create difficulties if it conflicts with Italian mandatory rules or if it does not clearly address assets located in Italy. The issue becomes especially delicate when the estate includes Italian real estate, because property transfers require registration formalities and must be aligned with Italian succession documents.

Another relevant distinction concerns testate and intestate succession. If the deceased left a valid will, the succession follows the testamentary provisions within the limits imposed by applicable law. If there is no valid will, or if the will cannot be effectively recognized for Italian purposes, the estate may pass according to statutory rules. For U.S. heirs, this can produce unexpected outcomes, particularly in blended families, second marriages or situations where one branch of the family resides outside Italy.

The practical consequence is clear: a succession involving Italian assets should not be assessed only through the lens of U.S. probate expectations. It requires a dedicated review of Italian inheritance law, the deceased’s nationality and residence, the location of the assets, the structure of the will and the family relationships involved. Early legal analysis helps determine whether the existing documents are sufficient or whether corrective steps are needed before the succession process becomes contentious.

Jurisdiction, applicable law and professio iuris under EU Succession Regulation 650/2012

In cross-border successions involving Italy, the question of applicable law is often as important as the identity of the heirs. Regulation (EU) No. 650/2012, applicable in Italy and in most EU Member States, introduced a unified framework for determining jurisdiction, applicable law, recognition of decisions and the European Certificate of Succession. Its purpose is to reduce uncertainty in international succession cases and avoid fragmented proceedings across multiple countries.

As a general rule, the Regulation connects the succession to the law of the State in which the deceased had habitual residence at the time of death. This criterion can be particularly relevant for U.S. citizens who spend significant time in Italy, own Italian property, hold residence status in Europe or maintain strong personal and economic ties with Italy. In practice, the analysis of habitual residence is not always mechanical; it may require a review of lifestyle, family connections, center of interests and long-term intentions.

The Regulation also allows a person to choose the law of their nationality to govern the succession through a mechanism commonly known as professio iuris. For a U.S. citizen, this may allow the choice of U.S. law, provided the election is made clearly and in the proper form, typically within a will or estate planning document. This choice can be highly relevant where the testator wants greater predictability and wishes to avoid the automatic application of rules that may not reflect their estate planning objectives.

However, professio iuris is not a formula to be inserted casually. The selected law must be coordinated with Italian formalities, local property rules, tax consequences and the possible existence of multiple wills. A U.S. will and an Italian will can coexist, but only if they are drafted to avoid revocation conflicts, inconsistencies and uncertainty about which document governs which assets. In cross-border planning, clarity is not a stylistic preference; it is a legal safeguard.

Italian inheritance tax and U.S. estate tax considerations

Italy applies inheritance tax to transfers resulting from succession, with rates and exemptions that depend on the relationship between the deceased and the beneficiary. Spouses and direct descendants or ascendants benefit from a high exemption threshold and a reduced rate on the taxable excess. Siblings, other relatives and unrelated beneficiaries are subject to different treatment, with lower or no exemptions depending on the category. For non-resident heirs, Italian inheritance tax may still apply to assets located in Italy, including real estate, bank accounts and certain corporate interests.

For this reason, an American heir should not assume that residence outside Italy removes Italian tax obligations. The location of the asset remains decisive in many cases. If the inherited estate includes an apartment in Rome, a villa in Tuscany, Italian bank deposits or shares in an Italian company, the succession may require tax filings and payments in Italy even when the heir lives permanently in the United States. The imposta di successione must therefore be assessed together with registration taxes, cadastral taxes and mortgage taxes where real estate is involved.

At the same time, U.S. citizens and estates may need to consider U.S. estate tax rules. The United States does not impose a federal inheritance tax on the heir as such, but the estate of a U.S. citizen or resident may be subject to estate tax if the value of the taxable estate exceeds the applicable federal threshold. For 2026, the IRS indicates a basic exclusion amount of USD 15,000,000, but estate tax planning should always account for the year of death, lifetime gifts, portability issues and future legislative changes.

The United States also lists Italy among the countries with estate tax treaty coverage. In practice, treaty analysis may be relevant when determining whether relief, credits or coordination mechanisms can reduce overlapping taxation. This area should be reviewed with caution because income tax treaties, estate tax treaties and domestic foreign tax credit rules do not operate in the same way. A coordinated review by legal and tax professionals on both sides of the Atlantic is often necessary to avoid duplicated costs and incomplete filings.

Practical steps for inheriting Italian assets

The Italian succession process generally begins with the collection and verification of core documents. These may include the death certificate, family status certificates, the will, identification documents for the heirs, Italian tax codes, asset documentation and, when the documents originate in the United States, certified translations and apostilles. The exact requirements depend on the type of asset and on whether the succession is testate, intestate or disputed.

A central filing is the dichiarazione di successione, the inheritance declaration submitted to the Italian Revenue Agency. This document identifies the deceased, the heirs and beneficiaries, the Italian assets included in the estate and the taxes due in relation to the transfer. Omissions or inaccurate valuations can create delays, penalties or later complications in registering ownership, especially where real estate is involved. For foreign heirs, the preparation of this declaration often requires coordination between legal counsel, tax advisors and technical professionals.

If Italian real estate is part of the estate, additional steps are usually required to update public records. These may include cadastral updates, land registry formalities and the payment of taxes connected to the transfer. A notary may be involved in authenticating documents, verifying the legal chain of title and supporting the formal recognition of the succession. Where a foreign will exists, its acceptance in Italy may require specific checks regarding form, translation, legalization and compatibility with the applicable succession framework.

Timing is also important. International heirs often underestimate the time needed to obtain U.S. documents, apostilles and certified translations suitable for Italian use. They may also discover that they need an Italian codice fiscale before they can complete filings, interact with banks or register inherited property. Addressing these formalities early helps prevent a common scenario in which the legal right to inherit exists in principle, but the heir cannot practically access or transfer the asset because the documentation is incomplete.

Estate planning strategies for U.S. citizens with assets in Italy

For U.S. citizens who own assets in Italy, planning should begin before the succession opens. A carefully drafted will can clarify the intended distribution of assets, identify the applicable law and reduce the risk of interpretative disputes. In many cases, it may be useful to prepare a separate Italian will limited to Italian assets, provided it is coordinated with the U.S. estate plan and does not unintentionally revoke previous testamentary documents.

The goal is not to multiply documents, but to make the estate plan enforceable in the jurisdictions where the assets are located. A U.S. revocable trust, for example, may be familiar and efficient in a domestic context, but its treatment in Italy requires specific analysis. Italy recognizes trusts in certain circumstances, but the civil law environment, tax treatment and registration issues are different from common law jurisdictions. A trust holding or affecting Italian assets should therefore be reviewed from both an asset protection and succession law perspective.

Lifetime gifts may also be considered as part of a broader wealth transfer strategy. However, gifts involving Italian assets can have tax, succession and forced heirship implications. Under Italian law, certain lifetime transfers may be relevant when calculating reserved shares, and they may later be challenged if they prejudice the rights of protected heirs. This is why donation planning should never be separated from the family structure and the succession objectives of the transferor.

Family holding companies and other asset management structures can be useful in more complex estates, particularly where Italian real estate or business assets must be preserved across generations. These tools may help centralize management, reduce fragmentation and provide clearer governance among heirs. Their effectiveness depends on careful drafting, tax assessment and periodic review. A plan that works when the family is unified may become fragile after marriage, divorce, relocation, birth of new heirs or changes in tax law.

Common mistakes that can delay or compromise an Italian succession

One of the most frequent mistakes is assuming that a U.S. will automatically resolves every issue connected to Italian assets. While a foreign will may be relevant and potentially effective, it must still be usable in the Italian legal system. Problems can arise when the will lacks appropriate formalities, conflicts with another testamentary document, ignores reserved heirship rules or does not identify Italian assets with enough precision. These defects may not invalidate the entire estate plan, but they can make the succession slower and more expensive.

Another recurring error is treating taxation as a secondary issue. Heirs may focus on ownership transfer and only later realize that Italian filings, valuation rules, tax payments or U.S. estate tax reporting should have been considered from the beginning. The risk is not limited to paying more tax than necessary; it can also involve penalties, missed treaty analysis, inconsistent valuations and difficulty proving compliance to banks, notaries or public authorities.

Documentation errors are equally common. Names may appear differently on U.S. and Italian documents, family certificates may not match the required format, translations may be incomplete and apostilles may be missing or attached to the wrong document. In domestic matters these issues may seem administrative, but in an international succession they can prevent the file from moving forward. The more jurisdictions involved, the more important it becomes to establish a clean documentary chain.

A final mistake is waiting until a dispute emerges before seeking advice. Once heirs disagree, deadlines are missed or assets are blocked, the legal strategy becomes more constrained. Preventive planning gives families more options: choice of law, coordinated wills, tax-efficient transfers, trust review, family governance and clear instructions for future heirs. In cross-border inheritance, time rarely simplifies the matter; usually it makes gaps more visible.

Why coordinated legal guidance matters in cross-border inheritance

Inheriting assets in Italy as a U.S. citizen requires more than translating documents or filing a single form. It involves the interaction of succession law, private international law, tax law, notarial practice and asset registration. Each component affects the others. A choice of law clause may influence heirship analysis; a tax position may depend on valuation; a real estate transfer may require documentary steps that should have been planned months earlier.

This is why a coordinated legal approach is essential for American families with Italian ties. The objective is not only to complete the succession, but to preserve the value of the inherited assets, reduce unnecessary exposure and protect the intentions of the deceased. Where the estate includes significant wealth, real estate or business interests, the legal review should also consider future planning for the next generation, rather than treating the inheritance as an isolated event.

ZagamiLaw assists individuals, families and international clients in matters involving Italian inheritance law, cross-border estate planning, trust and asset management, real estate transfers and international tax coordination. The firm’s experience with Italy–U.S. legal matters allows heirs and testators to address succession issues with a structured method, from the review of existing documents to the implementation of a complete estate planning strategy.

For U.S. citizens who own or inherit assets in Italy, early legal guidance can make the difference between a controlled succession and a process marked by delays, uncertainty and avoidable costs. A tailored consultation allows the family to understand which law applies, which documents are needed, which taxes may arise and which planning tools are suitable for the specific estate. In a transnational context, clarity is not only useful; it is a form of asset protection.
