Quite recent, maybe 6 months ago? I gather she put down the deposit from the sale of a previous flat, he MUST have gone in as a 'joint tenant' (otherwise presumably he wouldn't have attempted a claim at all) and was living with her (she was in a well paid job and was paying the mortgage) and I recall he either didn't work or did minimal paid employment; no kids, relationship fell apart, he took her to court for half the flat but lost?
Need to find out as precedence for a brewing case close to my heart!
