It's good that you are consulting a lawyer.
I wonder if taking out a reverse mortgage is helpful in these situations? That would allow the equity in the home to be used to pay the nursing home costs and your mother can remain in the home. You might want to ask a lawyer about that.
Often times it's less expense to provide for round the clock care in the home, and visiting nurses and doctors, rather than to use a nursing home. That depends on the type of care required, but it is another option.
These are difficult situations to deal with.
