In general terms maclaren is right, but that situation does not apply to you. From what you have said in your various posts, your husband did not have an estate - in other words there were no assets, only debts. His half share of the house was not an asset because it is in negative equity; the mortgage lender has first call on the value & there will be nothing left for anyone else.
The house was owned either as joint tenants or as tenants in common. (If it was the former, then your husband's share comes to you automatically & does not form part of his estate; if the latter then his share is left separately under the terms of his will or the intestacy rules.). However, because he had no estate, I think it doesn't matter which form of ownership you had. Just for clarity, if what you quote in your post is all the information there is on the land certificate about ownership, then it will almost certainly be owned as joint tenants.
So far as I can see you have no reason to worry about the Charging Order because it only related to your husband's share of the house & there will be no money left for the creditor once the house is sold & the mortgage paid off. However, do follow the advice given by Barmaid on your earlier post - she is a barrister & knows more about these things than any of the rest of us on here.
