In a per stirpes distribution, how do shares get allocated?

In a per stirpes distribution, shares get allocated based on the rights of the deceased individuals as determined by their relationship to the decedent. This means that if a beneficiary dies before the decedent, that beneficiary's share of the inheritance is passed down to their descendants. For example, if a grandparent leaves an estate to their children, and one of those children predeceases the grandparent, that child's share of the estate would then be divided among their children (the grandchildren of the grandparent). Thus, the allocation reflects the family lineage and ensures that descendants inherit their deceased parent's share, maintaining the intent of the distribution as per stirpes.
