All four schools work it the same way, and the classical name for it is munasakha. If the second deceased’s heirs are exactly the survivors of the first and inherit from him in the same proportions, you ignore the second death and make ONE division. Otherwise you solve the first estate, isolate the share that fell to the heir who then died, solve his own estate separately, and reconcile the two sums.
