An 82-year-old individual sold a residential property and is enquiring about capital gains tax exemption if they purchase a new property in their son's or grandson's name. The consensus is that the exemption applies when the individual reinvests the sale proceeds into a new residential property within a specific timeframe, not when purchasing in another person's name directly. However, recent rulings suggest potential avenues for relief, and it's advised to purchase in her own name and then gift or will the property to the desired beneficiary.
