Capital Gains Tax joint to sole after divorce

As part of our finance agreement my wife purchased my share of the marital home and I purchased her share of a second home. These were completed at market value. The second home had an original cost of 200k (100 each) and in the divorce valued at 330k. Therefore I purchased her share for the market value. Now selling property. What do I use as the cost for cgt? Is it the original 200 or the market value when transferred to my name. The deeds will show original cost but my purchase was the increased value. No cgt was applicable at the divorce finance agreement.

Hi,
Your initial 50% cost was 100k and the purchase of the other 50% was the market value £165k.  Add both together to obtain your acquisition cost for 100% of the property.
Thank you.
