“(a) Bys.36(2) of the Law of Property Act 1925 , a joint tenancy may be severed in equity in the same manner as a joint tenancy of a personal estate could have been severed prior to 1926. That has relevance because of the age of the authorities relied upon. (b) In Williams v Hensman (1861) John & Hen 546, Sir John Page Wood V-C described three ways in which a joint tenancy could be severed at 557: (1) by an act of any one of the persons interested operating upon their own share; (2) by mutual agreement; (3) (and as the Claimants rely upon in this case) “by any course of dealing sufficient to intimate that the interests of all were mutually treated as constituting a tenancy in common”. (c) The editors of Megarry & Wade (9th edition) note at 12-043 “Although it is not necessary that the joint tenants should have reached a concluded agreement, the acts and dealings with the property must indicate an intention by them that they should hold in common. Thus, periodic distributions of property amongst joint tenants or the apportionment of the profits of trade amongst the joint owners of a business on the assumption that they are tenants in common, has been held to constitute such a course of dealing.” (d) In contra to (c) it is noted at Page 192 that there is “no severance where the rents of jointly owned properties are used as a common fund for the maintenance of the joint tenants.”
“It follows that in the absence of some other identifiable error such as, without attempting an exhaustive account, a material error of law or the making of a critical finding of fact which has no basis in the evidence, or a demonstrable misunderstanding of relevant evidence, an appellate court will interfere with the findings of fact made by a trial judge only if it is satisfied that his decision cannot be reasonably explained or justified”
“After transactions for twelve years in which the property had been treated as part of a partnership between the brothers, one brother lived and died in the belief, encouraged by the other, that he was entitled to one half and after his death his brother acted on the same basis.”
