What should we do if someone we are in debt dies?
When people die, the possessions and receivables transfer to their inheritors. Someone who is in debt to the deceased then becomes indebted to his inheritors.
Therefore, the debt must be paid to the inheritors.
Due to the debtor not knowing the shares of inheritors, the best way is to find two just persons -who preferably know the inheritors- and ask them to receive the debt and distribute it among them according to their shares in inheritance of the deceased.
