Thank you all again for your advice. I did write this post over an hour ago then had to go out and obviously pressed a wrong key!
Jennifer, yes, I will have to wait until the chalet is sold to release any money simply because, without the money from that sale, my husband cannot pay the fees himself. The SW left a message on the phone on Thursday to say she had spoken to her manager who had said not to worry over the weekend and that they'd work something out - either a loan or deferred payment or whatever. What is in our current account won't cover more than a few days at the rates around here!
Chris, yes, the chalet was erected on site - way back in the 70's,so I think it definitely is a building. Even though it is leasehold, we don't pay ground rent.Some owners have bought the freehold but we all pay maintenance costs for the grass cutting etc regardless of whether free or leasehold.
JPG, yes, I'm familiar with the New Forest log cabins as I live very near by but surely, they are built on site too. As I've said above, I think the chalet has to be classed as an asset. I've accepted that. (Though I will try to ascertain this) even though I was aghast when I realised it was jointly owned - heaven knows why we thought it was in my name only. We bought it with a legacy I had - £10,000- 10 years ago and I guess we must have signed the Land Registry form or something - the memory is hazy now. The SS assessor who came to the house to complete the assessment form did say that if I could prove that it was bought with my inheritance, the could disregard that part of it, but that is impossible to do. It was bought a year later anyway and how can one prove that this is what the money was spent on. I rather wish we'd spent the money on something else now as it's proving such a problem, what with having to become a deputy and finding a trustee for the sale, all costing loads,as well as all this bother of it taking my husband temporarily over the higher threshold - but what's done is done and there's no going back now I guess.
As I said previously, I think I would have had to sell anyway as it is deteriorating and the annual upkeep was a bit of a drain, so I am trying to be philosophical about it even though it is galling to be giving half the sale money to SS's. Well, to the nursing home in reality but it amounts to the same thing! At least the cost of becoming a deputy will hopefully deplete it a bit!
Thanks again for all your support - as I said on the other thread - I am so glad I found you all.
