In what circumstances will a successor state be liable for the assets of a predecessor state?

Moreover, with respect to the landlords' claim that joint-and-several liability principles provide a judicially manageable standard for fashioning relief, the district court rejected that view and we agree. Such state law principles have no basis in international law, which is the body of law we must turn to in this case. See First Nat'l City Bank v. Banco Para El Comercio Exterior de Cuba, 462 U.S. 611, 622 n.11 (1983) (international, not state, law governs the allocation of liabilities among foreign states). Indeed, the landlords do not point to any case where a court applied such a rule to determine the liabilities of successor states based on the liabilities of a defunct predecessor state.
