What procedure is followed upon the death of a third or subsequent heir before the division of previous estates?

Primary text

If a third heir dies before division, their estate must be calculated, and their resulting shares from the already reconciled first two estates must be assessed. If these shares divide according to the third heir's estate proportions, the entire structure remains sound based on the prior reconciliation. If they do not divide soundly, reconciliation (*tawafuq*) is performed between the third heir's shares and their estate proportions. The reduced fraction (if they agree) or the entirety of the third estate's proportions then multiplies the confirmed total of the first two estates, and subsequent calculations follow the methods described for the second death.
