Legal Conclusions
42 As I indicated at the outset, there is no room on these facts for inferring the existence of any actual intention that a trust be created in favour of the first defendant. Subject to the defendants' entitlement to have their expenditure recouped, there is, in the events which have occurred, nothing unconscionable about the plaintiff's conduct, or the facts and circumstances, that would justify a declaration of constructive trust as to some part of the Wilberforce land, even if it were legitimate to do so. Compare Muschinski v Dodds (1985) 160 CLR 583; Baumgartner v Baumgartner (1987) 164 CLR 137. The plaintiff has not failed to fulfil any promise or assurance to his son. Nor, in the circumstances, was the son entitled to any expectation other than that he would continue to reside in the property with his father and that its improvements and its enhanced value would eventually pass to him on his father's death. This is the only relevant assumption that he made. That assumption has probably, but not necessarily, been defeated by the events which have occurred.
43 There are risks involved in spending money on another's property. But in this case there was, in my view, no "joint venture" for which the defendants contended. Neither the plaintiff nor his son had any intention that the son would have a beneficial interest in the property. A constructive trust should not be imposed if, in all the circumstances, there is an appropriate equitable remedy which falls short of the imposition of a trust: Giumelli v Giumelli (1999) 196 CLR 101. The principle that adequately protects the defendants is explained in the following analysis by McLelland J in Morris v Morris (supra) at 63:
However, in my view wider equitable principles operate in the present case. The plaintiff spent money on the defendants' property in the expectation, induced or encouraged by the defendants that he would be able to live there indefinitely as a member of their family. This expectation has been defeated by the occurrence of events which were not in contemplation when the money was spent and as a result of which any subsisting right of residence by the plaintiff in the property is now of no practical consequence. In my opinion, on the facts of this case, it would be unconscionable and inequitable that the defendants should now retain the benefit of the expenditure by the plaintiff of his money on their property free of any obligation of recoupment to him. Consequently an equity arises in favour of the plaintiff and the court must determine how in all the circumstances justice requires that the equity be satisfied. What a plaintiff in such a case as this should in justice receive will not necessarily correspond with what, when the relevant expenditure was made, he expected to receive.
44 Although some broad submissions were put to the effect that the equitable charge should secure more than the amount of the son's financial contributions and should, in some way, reflect the enhancement in value of the property, the defendants did not, in fact, present such a case. No evidence was adduced which would enable me to make such a finding. Even if I thought it was appropriate, I am in no position to speculate as to the extent to which the expenditure by the son contributed to the enhancement in value of the property between 1994 and 2010. A beneficial interest in any enhancement was never contemplated by the son, except, as I said, in the event of the property passing to him on his father's death.
45 This is, unfortunately, a case of a breakdown in a family relationship without blame being attributed to the plaintiff. But there was no unfulfilled promise on his part and no proper basis for a reasonable assumption by the son that he was entitled to a beneficial interest in the property during his father's lifetime. The minimum equity to do justice goes no further than that which I have outlined.
46 Further, the defendants have had the benefit of occupation of the Wilberforce land continuously since December 1995. At all material times, the plaintiff has been prepared to accede to the grant of an equitable charge to secure the expenditure by the son. He does not seek to set off against the amount of the charge an occupation fee in respect of the period from 1995 to 2010.
47 This approach is broadly consistent with that which applies in an analogous area of law relating to co-ownership. If a co-owner, or for that matter a tenant, effects repairs or improvements he will be entitled to an allowance but the amount of the allowance is the lesser of the value of the enhancement to the property and the cost of improvements or repairs. See Forgeard v Shanahan (1994) 35 NSWLR 206 at 223 (per Meagher JA):
If a co-owner in occupation effects improvements on the co-owned property, he may claim an allowance for any improvements in value effected by him. Such an allowance may be claimed in an action for partition. The allowance is not a reimbursement of the amount expended, but an allowance in respect of the amount by which the value of the property has been increased, not exceeding the amount expended, the 'value' to be ascertained at the commencement of the action. … Thus, in summary, a tenant who effects repairs, is entitled to an allowance for the lesser of the value of the enhancement of the property and the cost of effecting the repairs.
There is authority that no allowance for improvements will be allowed in favour of the occupying owner unless the non-occupying owner seeks to charge him with an occupation fee, so that the two rights are truly mutual: one cannot claim one without suffering the other.
Orders
48 I do not propose to go further than to declare that there should be a charge to secure the amount of $147,201.40. This is an appropriate minimum equity. Anything further is not justified by the facts, by the evidence that was put before me, and as a matter of principle. Interest should, however, accrue on the secured amount from the date from which the defendants give up possession to the plaintiff.
49 As I have been forewarned that the parties wish to make submissions as to costs having regard to certain offers that were made before the hearing, I will reserve costs.
50 The orders I propose to make, other than costs, are these:
