She hasn't made life terribly easy for anyone! The property will have to
be transferred to the sons in its entirety. The sons will have to raise
sufficient to pay out their father and cover the mortgage and the loan. So
the real question here is whether the sons can actually afford to become
responsible for the loan, the mortgage and paying out their father.
Whatever is done, there should be a
consent order in the divorce proceedings so that
neither party can come back at a later date asking for further provision
from the other.
