"… the search is primarily to ascertain the parties' actual shared intentions, whether expressed or to be inferred from their conduct. However, there are at least two exceptions. The first, which is not this case, is where the classic resulting trust presumption applies. Indeed, this would be rare in a domestic context, but might perhaps arise where domestic partners were also business partners: see Stack v Dowden, para 32. The second, which for reasons which will appear later is in our view also not this case but will arise much more frequently, is where it is clear that the beneficial interests are to be shared, but it is impossible to divine a common intention as to the proportions in which they are to be shared. In those two situations, the court is driven to impute an intention to the parties which they may never have had."
"the relevant intention of each party is the intention which was reasonably understood by the other party to be manifested by that party's words and conduct notwithstanding that he did not consciously formulate that intention in his own mind or even acted with some different intention which he did not communicate to the other party" (Lord Diplock in Gissing v Gissing[1971] AC 886 , 906). Examples of the sort of evidence which might be relevant to drawing such inferences are given in Stack v Dowden, at para 69. (4) In those cases where it is clear either (a) that the parties did not intend joint tenancy at the outset, or (b) had changed their original intention, but it is not possible to ascertain by direct evidence or by inference what their actual intention was as to the shares in which they would own the property, "the answer is that each is entitled to that share which the court considers fair having regard to the whole course of dealing between them in relation to the property": Chadwick LJ in Oxley v Hiscock[2005] Fam 211 , para 69. In our judgment, "the whole course of dealing … in relation to the property" should be given a broad meaning, enabling a similar range of factors to be taken into account as may be relevant to ascertaining the parties' actual intentions. (5) Each case will turn on its own facts. Financial contributions are relevant but there are many other factors which may enable the court to decide what shares were either intended (as in case (3)) or fair (as in case (4)). 52. This case is not concerned with a family home which is put into the name of one party only. The starting point is different. The first issue is whether it was intended that the other party have any beneficial interest in the property at all. If he does, the second issue is what that interest is. There is no presumption of joint beneficial ownership. But their common intention has once again to be deduced objectively from their conduct. If the evidence shows a common intention to share beneficial ownership but does not show what shares were intended, the court will have to proceed as at para 51(4) and (5) above. 53. The assumptions as to human motivation, which led the courts to impute particular intentions by way of the resulting trust, are not appropriate to the ascertainment of beneficial interests in a family home. Whether they remain appropriate in other contexts is not the issue in this case." 12. The contrast in approach by the court in cases of commercial enterprise is clearly illustrated by the decision of the Court of Appeal in Generator Development Limited v Lidl UK GmbH[2018] EWCA Civ 396 where Lewison LJ (paras 78 to 85) stated that: "78… this was a case of commercial parties, advised by lawyers, working at arms' length towards the conclusion of an agreement for a purely commercial enterprise…The application of the principles underpinning the Pallant v Morgan equity, in so far as they rest on the doctrine of common intention constructive trust, operate quite differently in a commercial context from the way in which they operate in a domestic context…But we have seen from Cobbe that the House of Lords firmly denied the applicability of proprietary estoppel in a commercial case like this one where each party knows that they are not legally bound. In this case, as in Cobbe, there can have been no expectation on either side that the parties were legally bound to each other. If the principles underpinning the Pallant v Morgan equity are the same as those underpinning proprietary estoppel (as Chadwick LJ considered them to be) it follows logically that if a proprietary estoppel claim cannot succeed, nor can a claim based on the Pallant v Morgan equity. 79. the proposed "joint venture" (if such it was) was expressly made "subject to contract"… As Lord Walker stressed in Cobbe, equity will not intervene in a case where the parties expressly agree that a putative agreement is binding in honour only. Likewise, in the Hong Kong case the Privy Council recognised that the use of the "subject to contract" formula means that the parties are not committed either in law or in equity… The mere fact that parties have agreed to engage in good faith negotiations for the making of a joint venture agreement is insufficient to support a constructive trust: Kilcarne Holdings Ltd v Targetfollow (Birmingham) Ltd[2005] EWCA Civ 1355 at [15] and [23]. 82. … there is some significance in the fact that (to the knowledge of Generator) Lidl's board had not approved the joint venture. In order to be able to invoke the Pallant v Morgan equity it must in my judgment be possible to say that the agreement or understanding in question is one which has been assented to by a person capable of binding the party in question; or who at least has ostensible authority to do so. 85. … it cannot be unconscionable to exercise a right which has been expressly reserved to both parties by means of the "subject to contract" formula; and which Generator had even more clearly reserved to itself in the draft lock-out agreement. As Lord Walker said in Cobbe (and as Arden LJ said in Crossco), it cannot be unconscionable for one party to follow a course which the other party has insisted was open to itself."
"These written submissions address the court's questions as to whether (in the event that the court accepts the Claimant's evidence that he paid the deposit and made subsequent mortgage payments) i.) the payment of the deposit gives rise to a resulting or a constructive trust; and ii) the effect of any subsequent payments made by the Claimant to the mortgage lender. It will be submitted that in relation to the first question, there would only be a presumed resulting trust because there was no clear agreement between the parties and no commitment from the Claimant to contribute to the purchase price (above the amount provided for the deposit). In relation to the second question, it will be submitted that there should be no presumption of a resulting trust because payment of the modest sums in question to the legal owner (and majority beneficial owner at equity) by a claimant in occupation would not be prima facie gratuitous transfers/apparent gifts such as would give rise to a resulting trust. Further, there can be no question that any constructive trust arises from these payments because there was no clear agreement that they should give the Claimant any rights in the property, and the Claimant cannot argue that the Defendant has acted unconscionably because he has had the use and occupation of a 5 bedroom house in Luton for over 10 years without reducing the principal mortgage loan and having only made payments which amount to less than market rent for that period."
