Proprietary Interest in UK Law

The first and fundamental question which must always be resolved is whether, independently of any inference to be drawn from the conduct of the parties in the course of sharing the house as their home and managing their joint affairs, there has at any time prior to acquisition, or exceptionally at some later date, been any agreement, arrangement or understanding reached between them that the property is to be shared beneficially.

It is merely the process by which a claimant demonstrates what has happened to his property, identifies its proceeds and the persons who have handled or received them, and justifies his claim that the proceeds can properly be regarded as representing his property. It identifies the traceable proceeds of the claimant's property. It enables the claimant to substitute the traceable proceeds for the original asset as the subject matter of his claim.

But the proprietary interest which equity is enforcing in such circumstances arises under a constructive, not a resulting, trust. Although it is difficult to find clear authority for the proposition, when property is obtained by fraud equity imposes a constructive trust on the fraudulent recipient: the property is recoverable and traceable in equity.

However, there is a consistent line of reasoned decisions of this court (two of which were decided within the last ten years) stretching back into the late 19 th century, and one decision of the House of Lords 150 years ago, which appear to establish that a beneficiary of a fiduciary's duties cannot claim a proprietary interest, but is entitled to an equitable account, in respect of any money or asset acquired by a fiduciary in breach of his duties to the beneficiary, unless the asset or money is or has been beneficially the property of the beneficiary or the trustee acquired the asset or money by taking advantage of an opportunity or right which was properly that of the beneficiary.

The only way in which I find it possible to rationalise the rule in Dunlop v. Lambert so that it may fit into the pattern of the English law is to treat it as an application of the principle, accepted also in relation to policies of insurance upon goods, that in a commercial contract concerning goods where it is in the contemplation of the parties that the proprietary interests in the goods may be transferred from one owner to another after the contract has been entered into and before the breach which causes loss or damage to the goods, an original party to the contract, if such be the intention of them both, is to be treated in law as having entered into the contract for the benefit of all persons who have or may acquire an interest in the goods before they are lost or damaged, and is entitled to recover by way of damages for breach of contract the actual loss sustained by those for whose benefit the contract is entered into.

A resulting, implied or constructive trust—and it is unnecessary for present purposes to distinguish between these three classes of trust—is created by a transaction between the trustee and the cestui qui trust in connection with the acquisition by the trustee of a legal estate in land, whenever the trustee has so conducted himself that it would be inequitable to allow him to deny to the cestui qui trust a beneficial interest in the land acquired.

I do not think that the proprietary interest in the damages necessarily postulates a pre-existing proprietary interest in the cause of action. The contrary view could be reached by an argument along the following lines. Any equitable proprietary right must be based on the contract between the insurers and the assured. But there are plainly factors pointing the other way and since the question was not fully argued I prefer to express no view on the point.
