[Latin: by the roots]
According to descent. When property in an estate or fund is distributed per stirpes, beneficiaries a generation removed from the primary class of beneficiaries receive between them the share attributable to their ancestor. For example, a will may leave property to A and B in equal shares with provision that if either predeceases the testator, the deceased beneficiary's children take his share in equal shares per stirpes. If, on the testator's death, both A and B have already died, A leaving two children and B three, A's children will each receive a quarter of the property, and B's children one-sixth each. Compare per capita.
