Hi Stephanie Vincent-Squibb,
There is no Capital Gains Tax liability on the transfer of assets between husband and wife and civil partners.
Helpsheet HS281 advises ""If you and your spouse or civil partner were living together at some time in a tax year, you can transfer assets between you at no gain or loss any time up to earlier of the end of the third tax year after that in which you ceased to live together or the date on which a court grants a divorce or annulment of marriage, or dissolution or annulment of a civil partnership.
Transfers of assets between you or your spouse or civil partner in accordance with a formal divorce or separation agreement or court order will be at no gain or loss without any time limit"".
