“ Although apparently not questioning the power of Florida to impose a charge upon the estate, the court concluded that such a charge was, absent express agreement by the parties to the divorce, improper under Florida law and that 'the judgment awarding such alimony was void and of no force and effect under the law of the State of Florida in which such judgment was rendered and will not be given full faith and credit in the courts of this state.' 147 W.Va., at 283, 127 S.E.2d, at 393. ”

“ The Florida alimony decree must be treated as if it were perfectly correct under substantive principles of Florida law. It cannot be argued that a rule of law imposing a burden on the estate of a divorced man who has had his day in court violates due process, and if the judgment is binding upon him, it is also binding on those whom Florida law considers to be in privity with him, so long as Florida does not seek to bind those who cannot be bound consistent with due process. That West Virginia must give the decree of alimony as broad a scope as that it has in Florida is clear, see Johnson v. ”
