Operational Case Studies
The UK Developer and the Italian Title Defect
A UK-based property developer purchases a commercial building in Milan through a valid Italian notarial deed (Rogito). Two years later, a third party emerges with a prior claim based on an unregistered trust. The developer cannot ask the English High Court to declare that their title is valid — this is a question of title to Italian land, squarely within the Moçambique prohibition. The developer must litigate in the Italian Tribunale Civile, applying Italian property law and the Italian system of registration priorities.
However, if the UK-based estate agent who brokered the deal warranted that the property was free of encumbrances, the developer can simultaneously pursue the agent in England for breach of warranty. The English court in this action does not adjudicate the Italian title — it simply determines whether the agent fulfilled their contractual obligations.
The Heir Asserting Italian Forced Heirship Against English Property
An Italian citizen dies domiciled in England, leaving a will governed by English law under a Brussels IV professio iuris. The testator disinherits a child, leaving the entire estate — including a London flat — to a spouse. The disinherited child obtains an Italian court judgment declaring that the London flat is subject to Italian forced heirship.
Under Rule 139 and the Pescatore v Valentino precedent, the English court will refuse to recognise this Italian judgment. The London flat is English immovable property. The Italian court has no jurisdiction to adjudicate rights in rem in English land. The child must apply to the English court and establish their claim (if any) under the applicable succession law.
The Partnership Dispute Over an Italian Vineyard
Two UK-resident partners invest jointly in a vineyard in Piedmont. The property is registered in one partner's name. When the partnership dissolves, the other partner claims a beneficial interest arising from their financial contribution. This is a trust claim — the non-registered partner asserts that the registered owner holds the property on constructive or resulting trust.
Under Webb v Webb, this claim can be heard in England. The English court acts in personam against the registered owner, who is within the jurisdiction. The court can declare that the registered owner holds the vineyard on trust and order appropriate relief. But the court cannot directly amend the Italian land registry — the successful claimant must then take the English order to Italy and apply for registration through the Italian Conservatoria, which will apply its own rules regarding the recognition of foreign judicial decisions.
The Formalities Warning: What the English Court Cannot Order
Even where the in personam exception applies, the English court is bound by Lord Cottenham's limitation: it will not decree an act that the lex situs (Italian law) forbids. This has several practical consequences:
The English court cannot order the execution of a transfer deed in a form that Italian law does not recognise. All transfers of Italian land must be executed before an Italian Notary in the form of a Rogito — an English court order cannot substitute for this formality.
The English court cannot override Italian norme inderogabili (mandatory rules). If Italian law requires that a property be sold only after certain urbanistic clearances are obtained, the English court will not order a sale that bypasses those requirements.
The English court cannot compel the Italian Conservatoria to accept a registration. The English court can order the party to take steps to effect a transfer, but it cannot guarantee that Italian authorities will recognise the resulting instrument.
Professional Legal Considerations
The Moçambique Rule defines the jurisdictional boundary that every cross-border property arrangement must respect. Practitioners advising UK-based clients with Italian property should structure their documentary framework with this boundary in mind.
Where a client purchases Italian property through a UK-based intermediary or agent, the contractual documentation should include express governing law and jurisdiction clauses that anticipate the possibility of a subsequent in-personam claim in England. Without such clauses, the enforcement of contractual obligations may be complicated by disputes about where the contract should be adjudicated.
Where a client suspects fraud or breach of trust by a UK-based counterparty in relation to Italian property, immediate advice should address the dual-track nature of the proceedings: the title question must be resolved in Italy, but the personal claim against the counterparty can proceed in England.
Where an Italian judgment has been obtained that affects English property, the client should be advised that the judgment is not enforceable in England and that fresh English proceedings will be required.

Authority Notes
The Moçambique Rule is established in British South Africa Co v Companhia de Moçambique [1893] AC 602. The in-personam exception is grounded in Penn v Baltimore (1750) and applied in Webb v Webb [1994] QB 696. The non-recognition of foreign judgments affecting English land was applied to an Italian judgment in Pescatore v Valentino [2021] EWHC 1953 (Ch.). The rule is stated as Rule 138 in Dicey, Morris & Collins on the Conflict of Laws (15th Edition), Chapter 24. The Italian PIL convergence is found in Article 51 of Law 218/1995 (lex rei sitae — Italian courts exercise the same exclusive authority over Italian land that English courts exercise over English land) and Article 64 (automatic recognition of foreign judgments — but subject to the ordine pubblico exception, which parallels the Moçambique principle).
