If one spouse remains in a jointly owned home and the other moves out and later on the home is sold, the share of the sale proceeds belonging to the spouse who stayed will remain free of CGT as it was their main home.nnAny capital gain on the other spouse’s share may be liable to CGT, but if the house is sold within 9 months of them moving out, then the exemption from CGT for their main residence will apply to the period of absence, but after that, a proportion of the spouse’s gain may be liable to CGT.
