Hi, As per some of the other cases, if I am the sole owner of a BTL property purchased before getting married (only my name on the land registry) with a mortgage in my name only at the moment, I can transfer beneficial interest to my wife by creating a deed of trust and informing the HMRC. My question is, do I create a deed of trust that reflects the exact ratio for both of us (90/10) and inform HMRC (without form 17) or do I need to create a 50/50 trust and then submit a form 17 to reflect the exact split? Furthermore, will a deed of trust trigger Capital Gains Tax or stamp duty given only my name is on the land registry and mortgage is currently in my name only? we’ve been married for over a decade. Many thanks
