You vary the destination of the half share for fictional tax purposes but in the real world the surviving joint tenant will own the entire asset. It is a question for the parties whether the survivor will also transfer a half share to the donee fictionally substituted for tax purposes by the DOV. Presumably if reading back is elected for IHT or CGT or both it must follow that such a transfer would then have no effect for the relevant tax purposes.
Words are important, particularly if they do not do the job intended or only do so after a judge has been prepared to hold that, as a matter of construction and on admissible evidence, they do or they don’t but can be rectified. The latter to me seems an expensive gamble worth avoiding.
The co-owner who has not survived is by definition unable to vary so only his PRs can be the necessary party to the DOV (together with the surviving co- owner). If the DOV just says “the PRs hereby sever the the deceased’s joint equitable interest in Blackacre” such wording literally must run the gauntlet of the case law.
I have not searched exhaustively but my understanding is that it is now settled that severance cannot be effected by Will (although it may be that where mutual wills are executed the agreement might bind the will makers on the first death but that is not severance in lifetime unless the agreement can be construed as a notice, another interpretation nightmare. A fortiori, the idea that PRs can sever is absurd as the entire property will have vested in the survivor: it is too late.
The main problem here is that, as usual, fiscal legislation has bulldozed over property jurisprudence and its deeming rules are at odds with its real world operation. A masterful analysis of joint ownership is “Plural Ownership” by Roger J. Smith, who spends 180 pages dealing with land and 20 with personal property, as ever the Cinderella of the law reports. It remains obscure how s.36 LPA 1925 applies to it, given the s.205(1)(xx) definition of “property” which does not figure in s.36.
The first tax fiction is s.4 (1) IHTA. The deeming of the TOV’s occurrence immediately before death allows the value of the deceased’s severable share to be charged. The second fiction is in s.142 and apparently (this ought to have been made clearer) allows a variation of the severable share charged under s4(1) as a “disposition…..or otherwise”. That variation must be made by the survivor as in the real world he owns the entirety. The DOV should say”X hereby varies the disposition made to him by operation of law of the share in Blackacre vested in him on the death of Y”. X should not purport to sever anything because he could only do so in the lifetime of Y and even then could only have severed his OWN share not that of the deceased, although of course that would have been the corresponding outcome if there was one other co-owner.
CGT is even murkier. In the real world it is strongly arguable that the deceased per s.62(1) TCGA was not competent to dispose at his death of his formerly severable share and there is no explicit timing fiction as for IHT. Presumably it must be inferred. Only then does s.62(1)(a) deem a relevant asset to be acquired by his PRs, plainly a fiction.
Other real world controversies concern whether there has been already a lifetime severance by conduct, whether a purported notice has already been given, and whether a lifetime transfer by a joint equitable owner that does cause severance of his own share affects the other shares where there is more than one surviving equitable joint owner. Fortunately tax law here seems to follow the real world property law, at least when the appropriate analysis of that has emerged definitively from the prevailing uncertainty of the law, let alone its application to the particular facts.
