I've tried to Google this but can't find any clear information so was wondering if anyone might know the answer through having been in the same situation. Basically, 20 + years ago XP and I had a loft conversion done on our terraced house. The council subsequently put a note on our council tax record which I believe is called an improvement indicator.
Around 10 years ago, XP left DC and me and 1 year ago I managed to buy out his share of the family home (we'd informally agreed when he left that we'd wait until DC2 finished secondary to finalise everything). I asked my conveyancer at the time whether this would count in the VOA's eyes as a sale and move me into the next council tax band and he didn't know.
The VOA website says that they can't change the council tax band of a property until it is sold. I know that my buying XP's share will have been noted on the land registry records but does anyone know if this meets the definition of sale? Does it need to be sale of the entire property or is a partial sale enough to mean the property will be rebanded? I haven't received any notification about a change but I am just wondering if this still might happen if there's a backlog in the system? How long until I can conclude that I can carry on in the current tax band?
