Capital gain exemption on sale of house

This discussion explores whether an individual can claim a Capital Gains Tax exemption under Section 54 after selling their house. The individual invested the full sale proceeds of £40 Lakhs into constructing a new house on land owned by their son-in-law. The consensus is that exemption is possible, provided the individual obtains a No Objection Certificate (NOC) from their son-in-law to use the land for construction and their residence.
