I own a house with my ex-partner - I lived there until we separated in Feb 22. I stayed with a friend for a couple of months, then rented a property for 12 months, then moved in with a new partner into a house they own in April 24. I have no financial interest in either the rented property or my current partner's house where I'm currently living. Am I able to nominate the property I own (currently on the market) as my main residence to avoid a CGT liability? My accountant has not mentioned this when asked, but it appears clear on the government website that this is the route I should take. Many thanks
