Husband and I buying new build using part exchange scheme. Our current property is in my sole name, however wanted to buy exclusively in his to save on stamp duty as he is a first time buyer. The developer has said this isn't possible and we'd need to buy in both names, however didn't provide much in the way of reasoning. I feel they just wanted to avoid any complications and complete the reservation. Is this correct, due to legalities of the part exchange scheme or is it possible to buy in just his name?
