can anyone help? My ex became bankrupt due to fraud so CCj's were never written off. I own all of the house having bought it from Trustee in Bankruptcy. Now divorced but on divorce ex gets half of my share in the house. Divorce agreement states I own property and am soley responsible for mortgage and maintenance payments until it's sold. Once the house is sold and ex gets lump sum will it be a capital gain? separated in 2021 and divorced at end of March 2022.
