There actually may be a few prospective buyers for the place, but it seems my sister still can't do anything because the thing I had to sign was 'improperly notarised', despite a big seal on it like something from Elizabethan days, etc.
I still haven't had the explanatory letter from her lawyer, but it's gotta mean yet more money and aggro. What a fuckin' waste! I suppose it will also involve another schlep to Balham, so I may get to see the suavely dishy solicitor again...That's not worth money, though! Grump.
