Buying out other beneficiaries

Hi, on my mothers passing our family home was left to myself and my three siblings equally. My daughter was already living in the property and wanted to buy it. So to make this possible I had a deed of variation drawn up by the solicitor and made her the forth beneficiary to the property. The house was valued at 390k, however it was agreed that this was a low valuation and that 400k was more reflective of the true value of the house. With her quarter share of the property she would buy the other three out of the property, paying 300k , 100k to each of her two aunts and uncle. This was completed, however now we are being told we may incur CGT on the extra 10k. Is this the case when the deed makes her a beneficiary and it’s a beneficiary who has bought the others share.

Hi 

Any increase in value of an asset when it is sold is subject to capital gains tax but as the amount you refer to is for more than 1 person then it will be below the annual exempt amount
Please see Capital Gains Tax: what you pay it on, rates and allowances

Thank you
