Succession is codified in the Codice Civile, prioritizing family protection through a mandatory "Reserved Share" system. The Notaio is required to record the succession and ensure the payment of mortgage and cadastral taxes.

The primary friction point is Forced Heirship (Successione Necessaria) versus the Common Law principle of Testamentary Freedom. In Italy, children and spouses are "Legitimary Heirs" who cannot be entirely disinherited without a valid choice of foreign law (Brussels IV).

The statutory framework for cross-border succession is based on Article 22 of EU Regulation 650/2012, which allows a testator to elect the law of their nationality to govern their entire estate (Professio Iuris). Crucially, the 2023 Universal Ruling (CJEU Case C-21/22) confirmed that this Choice of Law is universal, meaning US or UK citizens can override Italian forced heirship rules. The European Certificate of Succession (ECS) serves as the primary tool for providing standardized proof of heirship across the EU without further legalization.

A significant source of friction in 2026 is the "Renvoi Trap". Common law jurisdictions often follow a scissionary approach—splitting the estate between movables (domicile) and immovables (location). Without specific "Anti-Renvoi" drafting, an Italian Notary may look to English law, which then hands back jurisdiction of Italian land to Italy, effectively re-instating forced heirship. Furthermore, Article 458 of the Italian Civil Code explicitly prohibits Succession Pacts (Patti Successori), rendering English-style "Mutual Wills" or reciprocal spousal agreements entirely void in Italy.

Inheritance Co-Ownership Deadlocks (Comunione Ereditaria)**. In Italy, property is often inherited by multiple heirs in undivided shares. No single co-heir can sell or renovate without the unanimous consent of all others, often leading to decades of administrative paralysis. A "Practical Example" here is the "Oscar Pio" Case Risk—where friction between unitary and scissionary rules led to a 20-year legal battle. In 2026, the absence of a clear anti-renvoi mechanism or a pre-negotiated Private Settlement (Accordo Transattivo) can trigger a costly Judicial Partition (Divisione Giudiziale).
