I hold a buy-to-let property in my name which I assigned 100% beneficial interest to my spouse a few years ago using a Deed of Assignment. Since then the property income has been going to my spouse which she has declared in her self assessment annually. I have recently sold the property and so want to know if my spouse should complete the CGT return given she is has 100% beneficial interest. Can someone please help? Thank you.
