I fear this discussion is going down the same route as before with, in my view, little now to be gained.
I would like to make one final comment on Peter D's very last sentence:
If you had been single and you married out in Dubai and then you did an interspousal transfer do you really think HMRC would accept her PRR status on a rental property she owns 50% of as T in C if and when you sell it. I don't think so.
1.Man (M) owns 100% UK property (P). It is his sole residence.
2.M goes to Dubai for 1 month holiday.
3.M meets woman (W) .
4.M marries W in Dubai becoming H and W.
5.Assume W has had no electable residence (eg lived with parents).
6.On the day of marriage H and W can only have one sole (or main) residence. W’s sole residence is thus P even though W has not lived in it (whether or not P is rented out is irrelevant). This arises because the legislation effectively treats H and W as one individual.
7.Two months after marriage whilst in Dubai H transfers 50% of P to W.
8.One month later whilst still in Dubai P is sold.
9.The capital gains of each of H and W will be cgt free due to PPR relief even though for W she has not actually lived in P (assume that W is a UK resident as otherwise, of course, no cgt for her in any event).
For better or worse no more comments from me on this issue. Good luck !
