Hi,
You need to pay Capital Gains Tax when you sell (or 'dispose of) an asset if your total taxable gains are above your annual Capital Gains Tax allowance. So as you are acting as the purchaser
you will not be liable for CGT at this time. However your daughter might be. You can find out more information here:
Capital Gains Tax
You may also wish to speak to Inheritance Tax regarding any inheritance tax implications:

Thank you.
