Thanks Lucy
Not sure that helps Tinky, that seems to refer to houses that have previously had a charging order applied - that's not the case here. The situation I'm thinking of would be two people who have an equal legal interest in the property (50:50), but where only one of those people wants to sell.
I had hoped that the order of sale would be the way forward, but from reading your link I'm now thinking that it might not be.
Thanks though
