Could someone please give me some idea as to how long it takes for a spouse to become a deputy, when it is too late to be made a LPA, in order to sell property on behalf of the person who is now unable to make decisions?
You can do an LPA online (link below) and they quote a time of about 10 weeks.
"When is it too late" is a difficult one, if tests have taken place and doctor's letters written saying your OH lacks capacity then it could be challenged if anyone might feel you'd taken advantage, if that's not likely to happen then you should be OK.
I only ever had DWP appointee status for my (now late) mother but I managed to sell her house without a problem, theoretically that only allowed me to deal with her benefits so I was winging it a bit but neither the estate agent nor the solicitors ever raised an issue and I never had to forge a signature (not that I would, honest).
You do say sell a property on behalf of a spouse (as I read it) if it's the matrimonial home I'd give it a go, if it's a property they have inherited (for example) and you're name isn't on the deeds then you may have to go down the COP route with all the expense and grief that involves.
