HMRC Admin 8 Response

I separated from my husband 1/01/2019 and divorced 26/03/2020 we owned 2 houses I remained in the family home and he moved into the other house that we both previously lived in together as a couple. In 2020 he completed a TR1 form and transferred the family home into my sole name, I remained jointly on the deeds and mortgage for the other house. Agreed a consent order this week made formal in court. He is to pay me a lump sum and I will be removed from the mortgage and sign TR1 for transfer of the second property into his name. He is not selling the 2nd home and is paying the lump sum from savings. My question is am I liable to pay capital gains tax on this lump sum, i have looked at all the pages on HMRC site and forum and am very unclear. I have also looked at the new rules and still don't understand my position. Thanks for any advice.
