Is it permissible to divide the inheritance amount, or must the apartment's debt be paid off first, knowing that the grandmother wants her share of the inheritance?

The debts of the deceased, the expenses for preparing their body, the costs of their burial, and their bequests must be settled first from the estate before its distribution, even if the debts consume the entire estate. A debt becomes due immediately upon the death of the deceased. Money should be withdrawn from interest-based banks because it is impermissible to deal with them.
