CGT of main residence

A property, which is the main residence of a married couple living there for over 10 years, was sold with capital gain. May I know whether the married couple could be treated as single entity and share the capital gain if only one of them is the owner in the legal document but both of them are the “borrower” for the mortgage in the legal document? If yes, may I know the percentage of capital gain to be shared between this married couple?

Hi,
If this was your main residence for the whole period of ownership then it is sold at a no loss/gain to report. See guidance at:
Capital Gains Tax: what you pay it on, rates and allowances
Thank you.
