I see you are waiting to hear from me.
Anyone who suffers from mental illness deserves our sympathy and understanding.
I have been thinking about what I might say to you, because I am conscious that I am not an expert in mental health, nor do I pretend to be.
I do not wish to recount to you the history of my first star-crossed marriage, save only to say that I never blamed my ex and even after divorce I kept in touch, sent her presents on her birthday and for Christmas, and time is a great healer.
For most of the time afterwards my ex was in a care home, as you are.
My general understanding was that a patient is allowed to keep capital up to a certain figure ( it''s about £15,000, but I''m not sure and it varies each year anyway ) and if the patient has capital in excess of a certain figure ( I think it''s about £22,000 ) then (s)he will have to bear the full costs of the care home until the capital is reduced to below the £22K.
Now if we look at this from the point of view of the situation you are in, the fact that you suffer from mental illness is not a reason for depriving you of your entitlement to share in the fruits of a failed marriage.
In my case the marital home
was sold and she got 2/3 of it, a settlement which I regarded as fair ( and still do ) but I suspect her circumstances and yours would be different.
But what a Court has to do is to try and divide the assets fairly between the former spouses. The most basic need both of you have is somewhere to live. In your case you have, as I understand, children. I didn''t, and it would have made a difference to the settlement if I had done.
As I said, the Courts are directed by statute to give priority to the needs of any dependent children of the marriage. In most cases this means that the needs of the parent with care ( PWC ) will take priority. This can mean that the PWC may have the right to remain in the former marital home until the children are no longer dependent. If the marital home is sold, she ( without wishing to be sexist, it usually is the mother ) may have a larger share of the equity.
But this does not mean your own needs are unimportant. You have to have somewhere to live too. What you are being offered is, on the face it, a disproportionately low share of the proceeds. But if there are other assets - not just the marital home - then they have to be considered too and in principle you would be entitled to a share in those assets.
Given the nature of your illness, your housing needs require careful consideration, probably by professionals. But if you can come away with enough to buy yourself accommodation outright, then this may be the solution you should be aiming at.
I say this because £40-50 K in the bank will immediately disqualify you from all means tested benefits, but capital which is used to buy accommodation for your own use is not counted against you.
I have to stress that I can only talk generally here. It seems to me that your future housing needs must be assessed as a first step.
