54 The emphasis is on specific intention or special provision by agreement. Here I have found that the parties intended that they would both be beneficially entitled to the property as joint tenants. I have found that Mr Brennan formed that intention after considering advice from the parties' solicitor which adverted to the possibility of separation and to alternatives in relation to the holding of property or the making of specific agreements to deal with the consequences of separation. Nonetheless, I have also found that when the property was acquired Mr Brennan expected the relationship to be a lasting one. One of the reasons for which I have inferred that Mr Brennan intended that Ms Duncan should beneficially take as joint tenant was that the parties expected that the arrangement for meeting expenses from her income would continue. More importantly, he expected that all of the benefits from their relationship as de facto husband and wife would continue.
55 In my view, he did not have a specific intention as to what should happen to the property if the parties separated only months after its purchase. I am satisfied that he would not have intended to make a substantial gift of a beneficial interest in the property to Ms Duncan had he contemplated that their relationship would end before April in the following year.
56 It was submitted by counsel for Ms Duncan that the conduct of the parties after separation showed that they both intended that Ms Duncan have an interest beneficially as joint tenant even after separation. However, I think that conduct is equally referable to their intending, when the property was purchased, that she should have a beneficial interest as joint tenant. The parties acted on the basis of that intention after separation. It does not follow that when the property was purchased, Mr Brennan intended that Ms Duncan should enjoy an equal ownership of the property even if the relationship failed only months later. That possibility did not come up for consideration.
57 Accordingly, I consider that Mr Brennan is entitled to have his contribution of $90,500, or 13.6% of the purchase price, restored to the extent it would be unconscionable for Ms Duncan to retain that benefit.
58 That raises the question, which it was not necessary to determine when dealing with the earlier claims, of the extent to which Mr Brennan's contribution of funds to the purchase price was matched by Ms Duncan's meeting his or Rosepool's personal expenses, or by her contributing more than half of their joint expenses. To the extent she did so, it would not be unconscionable for her to retain the benefit of Mr Brennan's contribution to the purchase price. The onus lies on Mr Brennan to show the extent to which it would be unconscionable for Ms Duncan to retain the benefit.
59 It was submitted by counsel for Ms Duncan that, by reason of the arrangement for meeting expenses, the moneys contributed by Rosepool were held on trust for her. That cannot be right. I see no basis for saying that Rosepool's money was held on trust for Ms Duncan. Nonetheless, it would not be unconscionable for her to retain the benefit she received to the extent that she advanced the interest of Mr Brennan or Rosepool by meeting expenses beyond what was originally agreed in September 2000.
60 The figures referred to earlier show that Ms Duncan made a contribution to such expenses of between $25,400 and $60,000. The evidence is unclear within that range. However, assistance can be gained from considering Ms Duncan's income. There is no evidence that she had any substantial savings on which to draw to meet such expenses. The evidence of the income available to Ms Duncan at the relevant time is not very satisfactory as she did not prepare tax returns. However, her group certificates for the relevant periods show that she received income after deduction of tax as follows: 1 July 2000 to 21 December 2000, $29,773; 2 January 2001 to 30 June 2001, $31,840 plus a car allowance of $7,500; and 1 July 2001 to 27 June 2002, $71,524 plus a car allowance of $15,000.
61 The period from December 2000, when the savings plan started, to March 2002, when the parties separated, was about 15 months. On the basis of these figures, the available after tax income was about $90,000 plus the car allowance. Ms Duncan owned her own property at Darlinghurst which was negatively geared and which cost at least $8,000 during this period. Her half share of the parties' joint expenses for rent and the American Express bills alone totalled $25,300. She would have had other personal expenses and contributions to joint expenditure. Taking into account her available income after meeting these expenses, it is safe to conclude that her contribution to the personal expenses of Mr Brennan and Rosepool, and her contribution to more than 50% of the parties joint expenses, did not exceed $45,000.
62 I therefore conclude that it would be unconscionable for Ms Duncan to retain the benefit of the contribution to the purchase price made by Mr Brennan to the extent of the difference between $90,500 and $45,000; that is, $45,500 or 6.9% of the purchase price. It is impossible to make a precise calculation on these matters and I will round that figure to 7% (see Baumgartner at 150).
63 In Muschinski v Dodds, the principle which I have quoted was applied by the Court's ordering that the parties' respective contributions be repaid and the proceeds of sale of the property divided equally after that division. A different remedy was applied in Baumgartner, where the parties had pooled their funds to acquire property. The beneficial interests were held in the proportion of the parties' actual and notional contributions to the pooled funds, and then subject to other adjustments.
64 Here, the relevant contribution to be restored is a contribution to the purchase price of property which has appreciated, and probably depreciated, over time in accordance with the changes in the property market. For better or worse, the parties invested in the property market. The appropriate way, in my view, to restore to the plaintiff the contribution to the purchase price in circumstances where it could not have been intended that the defendant enjoy that contribution, and to the extent it is unconscionable for her to retain it, is by imposing a constructive trust in Mr Brennan's favour to the extent of 7% of the beneficial interest in the property.
65 I will, therefore, declare that the property is held by the parties on trust for themselves in the proportion of 57% to the plaintiff and 43% to the defendant.
Charge to Secure Repayment of Contribution
66 I deal next with the plaintiff's claim to a charge to secure repayment of his contribution. Counsel for the plaintiff submitted that Mr Brennan was entitled to a charge or equitable lien over the property to secure the repayment of his contribution to the purchase price of $181,000. Counsel referred to Morris v Morris [1982] 1 NSWLR 61. There, McLelland J (as his Honour then was) held that a man who paid money for the extension to the house of his son and daughter-in-law, for the purpose of providing accommodation for himself, was entitled to a charge over the land to secure repayment of his expenditure when that purpose became incapable of fulfilment.
67 I do not consider that case to be relevant to the present facts, except that it lies in the same general area of discourse. In my view, this case falls to be decided on the principles applicable where title to land is put in the names of two parties, with one providing the majority of the costs of purchase, and by the principles applicable where one party makes contributions to a joint endeavour which fails in circumstances where it was not intended that the other party should enjoy them.
68 There is no utility in pointing to other remedies which may be available in other factual circumstances which bear no relationship to the present case. Here, the demands of good conscience are satisfied by the trust which I have found to exist and, accordingly, I reject this claim.
Contribution
69 I turn then to the claims for contribution.
70 The plaintiff is entitled to contribution of 50% of the mortgage payments made by him since August 2003. Those payments were made to satisfy a joint debt. He is entitled to a charge over the property to secure the right of contribution (Ingram v Ingram at 102; Currie v Hamilton at 692-693; Calverley v Green at 263).
71 He is not entitled to receive less than 50% contribution to those mortgage payments by reason of the defendant's having a 43% beneficial interest in the property. Her borrowing of half the purchase cost has already been taken into account in determining the quantum of the contributions which the plaintiff is prima facie entitled to have restored to him; that is, 13.4%, not 50%.
72 I do not consider that Mr Brennan is entitled to an adjustment with respect to the excess payments to the mortgage he made before August 2003. This was apparently due to his acquiescence in the plaintiff's demand arising from the loan being a "low doc" loan. The arrangements which the parties made at that time should not be disturbed for the period during which the parties acted on them. However, I do not consider that the reasons advanced by Ms Duncan as to why it was equitable for Mr Brennan to pay more than 50% of the mortgage are such as to warrant any different amount of contribution following August 2003. As I have said, neither party was in a position to provide a lender with tax returns. In any event, both parties joined in the mortgage on the terms which were then offered by the lender.
73 The parties are also jointly liable for rates and strata levies. Mr Brennan is entitled to contribution from the defendant in respect of his payments of those rates and levies since August 2003. However, as he will enjoy 57% of the fruits of the property he is only entitled to contribution in respect of 43% of those payments.
74 It is a condition of the plaintiff obtaining a declaration of a constructive trust of the property, and declarations as to the defendant's obligation to make contribution, that he do equity. To do equity, he is required to account for 43% of the rents received by him. To do equity, he is also required to make contribution to Ms Duncan for 14% of the contribution made by her in payment of rates, levies and other expenses, that is to say, 7% of the total of such payments. By the same token, on an accounting, the defendant should give credit for 7% of the rents received up to August 2003. These were applied in reduction of the principal, and after the adjusting contribution of $5,000 is taken into account, the parties have shared equally in those receipts.
75 Finally, Ms Duncan contended that on an accounting, Mr Brennan should be surcharged for an amount of rent which was not received for a period of some weeks after August 2003 when the property was vacant. I doubt that a co-earner is liable to be so surcharged (Forgeard v Shanahan (1994) 35 NSWLR 206 at 221-224). In any event, the evidence does not establish that Mr Brennan was in any way at fault in the property being vacant for a period between tenancies. I do not accept that the defendant is entitled to the benefit of such an adjustment.
76 I am conscious that the plaintiff has not claimed any of the remedies to which I have concluded he is entitled. He sought more extensive relief, which I have refused. This may well have costs consequences. However, I am satisfied that the way in which I have resolved the issues is within the parameters of the parties' respective cases fought at the trial. I will, therefore, stand over the proceedings to a convenient date for counsel to bring in short minutes of order consistent with these reasons and to hear argument on the question of costs.
