“…if the parties intend to make a formal agreement setting out the terms on which one or more of the parties is to acquire an interest in property, or, if further terms of that acquisition remain to be agreed between them so that the interest in property is not clearly identified, or if the parties did not expect their agreement to be immediately binding, neither party can rely on constructive trust as a means of enforcing their original agreement. In other words, at least in those situations, if their agreement (which does not comply with section 2(1) [Law of Property (Miscellaneous Provisions) Act 1989 ]) is incomplete, they cannot utilise the doctrine of proprietary estoppels or the doctrine of constructive trust to make their agreement binding on the other party by virtue ofsection 2(5) of the 1989 Act ”. when she commented (at her para. 93): “In this case the parties did not deliberately leave matters on a speculative basis, but they did leave matters without certainty. It is an unfortunate consequence for the parties dealing with matters in the manner in which they were dealt with in this case, that is in a more free-flowing and vague basis, because these were arrangements between members of the community which were changing. It is a not usual situation [sic] for a party who agrees to purchase a commercial property for the running of a business to enter into that commercial property and, after a short while, decide it is not really for them and therefore seek to pass on that property and the business to another. 94. …there was, …a lack of completeness to the agreement. That is an inevitable consequence of these matters being dealt with in the way that they were. First, there was a lack of agreement as to when completion of the purchase would, in fact, take place. Secondly, and potentially of more significance, there was a lack of ability on behalf of the Claimant to complete the agreement. One of the important matters in the agreement was for the mortgage to be taken over by the purchaser. There is no evidence in this case that the Claimant was in a position either to discharge the mortgage that was already outstanding on the property, or to obtain her own mortgage. That is not only because at the time she had a precarious immigration status, but also because of her questionable ability to service such a mortgage. Her purported intention has been to obtain a mortgage in the name of someone else. But that, of course, is fraught with all sorts of difficulties and not least the uncertainty of such an arrangement.”
“In other words, at least in those situations, if their agreement (which does not comply with Section 2(1)) is incomplete, they cannot utilise the doctrine of proprietary estoppels or the doctrine of constructive trust to make their agreement binding on the other party…”
“The benefit of having the property, which was either one worth in the region of£500,000 as the Defendants seek to say it was worth, or at the very least£350,000 (or thereabouts) as the mortgage plus the monies spent would seem to indicate, is a transaction which benefitted the Claimant. She was receiving a property which was worth more than the money she in fact was spending on it. On the face of it, therefore, the evidence is that this was a transaction which requires an explanation. Mr Desari, who was in a position of trust and confidence, had benefitted from the transaction. At the time of the transaction, he was in an intimate relationship with the Claimant purchaser. By reason of the sale of the property to the Claimant, he was being relieved of his potential liabilities, having stood as guarantor to Mr Chirumamilla in those circumstances, the requirements of Bank of Scotland v Etridge ([2001] UKHL 44 ) of the transaction requiring an explanation and him being in a position of trust and confidence are made out. If it were a case that there was an enforceable agreement for the sale of the property, then in my judgement, it is an agreement which would be impugned and potentially liable to be voided by reason of the presumption of undue influence…”
“there is a clear line of authority from at least Crabb [Crabb v Arun District Council[1976] Ch 179 ] to the present day which establishes that once the elements of proprietary estoppels are established an equity arises. The value of that equity will depend upon all the circumstances including the expectation and the detriment. The task of the court is to do justice. The most essential requirement is that there must be proportionality between the expectation and the detriment.”
“The oral agreement in principle that had been reached, i.e. the core terms, did not cover everything that would have been expected in due course to be dealt with in a formal written contract. It must have been expected, for example, that Mrs Lisle-Mainwaring would have wanted some provision to be included in the formal contract regarding the reasonably expeditious commencement and progress of the development and, also, some security and timetable for the payment of the appellant's share of the excess over£24 million of the gross proceeds of sale. The nature of the transaction would plainly have excluded reliance on a vendor's lien. Mr Cobbe, for his part, would probably have wanted some contractual assurance as to the timing of the availability of vacant possession of the block of flats. These would not have been expected to have been difficult matters on which to reach agreement but were all matters for future discussion, and the outcome of future negotiations has always an inherent uncertainty.”
“The terms of the oral "agreement in principle"... [were]... contractually, an incomplete agreement. The terms that had already been agreed were regarded by the parties as being "binding in honour", but it follows that the parties knew they were not legally binding. So what is it that the appellant is estopped from asserting or from denying? The appellant cannot be said to be estopped from asserting that the second agreement was unenforceable for want of writing, for Mr Cobbe does not claim that it was enforceable; nor from denying that the second agreement covered all the terms that needed to be agreed between the parties, for Mr Cobbe does not claim that it did; nor from denying that, pre18 March 2004 , Mr Cobbe had acquired any proprietary interest in the property, for he has never alleged that he had. And what proprietary claim was Mr Cobbe making that an estoppel was necessary to protect? His originally pleaded claim to specific performance of the second agreement was abandoned at a very early stage in the trial (see para.8 above) and the proprietary claims that remained were claims that the appellant held the property on trust for itself and Mr Cobbe. These remaining proprietary claims were presumably based on the proposition that a constructive trust of the property, with appropriate beneficial interests for the appellant and Mr Cobbe, should, by reason of the unconscionable conduct of Mrs Lisle-Mainwaring, be imposed on the property. I must examine that proposition when dealing with constructive trust as a possible means of providing Mr Cobbe with a remedy, but the proposition is not one that requires or depends upon any estoppel.”
"The fact that the constructive trust remains predominantly remedial does not, however, mean that it represents a medium for the indulgence of idiosyncratic notions of fairness and justice. As an equitable remedy, it is available only when warranted by established equitable principles or by the legitimate processes of legal reasoning, by analogy, induction and deduction, starting from the conceptual foundations of such principles … Under the law of this country - as, I venture to think under the present law of England … proprietary rights fall to be governed by principles of law and not by some mix of judicial discretion, subjective views about which party 'ought to win' … and the 'formless void' of individual moral opinion …"
“a claim for the imposition of a constructive trust in order to provide a remedy for a disappointed expectation engendered by a representation made in the context of incomplete contractual negotiations is, in my opinion, misconceived and cannot be sustained by reliance on unconscionable behaviour on the part of the representor.”
“…if a solicitor has bought property from his client and it is properly put in issue that the purchase was at an under-value or that the client's consent may have been improperly obtained, the solicitor will have to show that the price was fair and that the client's consent to the transaction was freely given in knowledge of the true facts. The solicitor has to justify what he has done. He has a burden of proof to discharge and if he fails to discharge it he will not have succeeded in justifying his conduct. Thus, at the trial the judge will decide on the evidence whether he is in fact satisfied that there was no abuse of confidence.”
