My partner and his sister own a property (my partner lives in) for 17 years. Would like to swap to tenants in common so she has the smallest share as she hasn’t paid in , when they sell after being made tenants in common (10% share to 90% share) does either one pay capital gains tax ?

House owned by siblings, one lives in it as primary residence. The other never lived in it. If they were to do transfer of equity and have the name taken off the mortgage of the sibling who doesn’t live there , would any capital gains be payable ?
