Introduction to the Issue
In conflict of laws, the "essential validity" of a transfer of property refers to whether a transaction is effective in passing title from one person to another. When property is moved or dealt with across different countries, a key question arises: which country's law should determine whether the transfer is valid? For example, if goods are stolen in Italy and sold to an innocent buyer in England, does Italian or English law decide if the buyer gets good title? English private international law provides specific rules to answer this, which depend on the nature of the property involved.
The Foundational Distinction and the Lex Situs Rule
The first step in any analysis is to classify the property as either immovable or movable. Immovable property generally means land and things attached to it, while movable property refers to tangible goods or chattels.
For both types of property, the governing principle is the lex situs, which means the law of the place where the property is physically located at the time of the transaction that purports to affect title (Dicey, Morris & Collins, 2022). The application of this rule, however, differs slightly between the two categories.
Transfers of Immovable Property
The rule for immovable property is straightforward and absolute. All questions concerning the essential validity of a transfer of land are governed exclusively by the lex situs. This is because the land is physically part of the country where it is located, and that country's courts are seen as having ultimate authority over it.
For instance, in Re Ross [1930] 1 Ch 377, the court held that the law of Italy determined the succession rights to immovable property situated in Italy, even though the deceased was domiciled in England. This illustrates the firm grip of the lex situs rule on land, covering issues like the capacity to transfer, the formalities required, and the type of interest created.
Transfers of Tangible Movable Property
For tangible movables, the lex situs is also the governing law, but its application can be more complex because the property can move. The classic authority is Cammell v Sewell (1860) 5 H&N 728. In this case, timber being shipped from Russia to England was shipwrecked off the coast of Norway. The master of the ship sold the timber in Norway in a manner that, under Norwegian law, passed good title to the buyer. The original English owners sued the buyer in England. The court held that the Norwegian sale was valid. The key principle established was that if a transfer of movable property is valid and effective according to the lex situs at the time of the transaction, that transfer will be recognised as valid in England.
This principle was more recently affirmed in Winkworth v Christie, Manson & Woods Ltd [1980] Ch 496. Artworks were stolen from the claimant in England and taken to Italy, where they were sold to an Italian buyer who acted in good faith. Under Italian law, this transaction conferred good title on the buyer. When the artworks reappeared in England, the original owner was unable to recover them because the title acquired validly under Italian law (the lex situs at the time of the sale) had to be recognised by the English courts.
It is important to note that the lex situs rule applies to the proprietary aspects of the transfer (the transfer of title), not the contractual aspects. The contract of sale itself would be governed by its own separate choice of law rules, today found in the Rome I Regulation (Regulation (EC) 593/2008).
