6. It does not matter whether the trust in the present case be regarded as an express trust (not created by an instrument) or a resulting trust, for, as will be seen, the result will be the same in either case. Mr Hodgekiss, who appeared for the respondent, challenged the correctness of the assumption made by this Court in framing its order in granting special leave to appeal; he submitted that there was no presumption in equity that where two persons advance equally the purchase money for a property the property is held for them beneficially as joint tenants; in such a case, he said, equity follows the law, with the consequence that in New South Wales before the enactment of s.26 of the Conveyancing Act the purchasers would have taken as joint tenants, whereas after that enactment they would take as tenants in common. At common law in England before the reform of the law of property in 1926, if land was conveyed to two or more persons a joint tenancy of the legal estate was created, unless either one of the four unities (of estate, time, possession and interest) was absent, or words of severance were employed: see Megarry and Wade, The Law of Real Property, 5th ed. (1984), at pp.424-425, where it is explained that the presumption at law in favour of a joint tenancy had its origins in the fact that in earlier times a joint tenancy was preferable to a tenancy in common, both to feudal lords and feudal tenants and to conveyancers. In this respect equity did not follow the law - in general, equity preferred tenancies in common, probably to give effect to the maxim "equity is equality". Where land was conveyed to two or more purchasers, all of whom had provided some of the purchase money, equity drew a distinction: if the purchase money had been provided in equal shares, the purchasers took beneficial interests as joint tenants, but if the money had been provided in unequal shares, they took as tenants in common. For completeness it should be added that even if the contributions are equal, equity will hold that there is a tenancy in common where two or more persons advance money and a mortgage is made to them jointly, or where the persons to whom the property is conveyed acquire it as partners or as participants in a joint undertaking; these are not rigid categories: Malayan Credit Ltd. v. Jack Chia-MPH Ltd. (1986) 2 WLR 590, at pp 595-596. The decisions usually cited as authority for the proposition that purchasers who have contributed equally to the purchase price hold the equitable as well as the legal estate as joint tenants were all cases in which the legal estate was conveyed to the purchasers: see Lake v. Gibson [1667] EngR 103; (1729) 1 Eq.Ca.Abr. 290 (21 ER 1052); affirmed sub. nom. Lake v. Craddock [1732] EngR 132; (1733) 3 PWms. 158 (24 ER 1011); Aveling v. Knipe [1815] EngR 947; (1815) 19 VesJun. 441 (34 ER 580); Robinson v. Preston [1858] EngR 426; (1858) 4 K.&J. 505 (70 ER 211); Palmer v. Rich (1897) 1 Ch 134. Writers of high authority have explained this result by saying that where the purchasers had contributed equally there was no reason why equity should not follow the law. Thus in Maitland on Equity, revised by Brunyate, (1936), at p.79, it is said that:
