Kautilya's Arthashastra 3.5.5

3.5.5

tāvad avicchinnaḥ piṇḍo bhavati //

Self-acquired property of any of the sons with the exception of that kind of property which is earned by means of parental property is not divisible. Sons or grandsons till the fourth generation from the first parent shall also have prescribed shares (amsabhájah) in that property which is acquired by means of their undivided ancestral property; for the line (pindah) as far as the fourth generation is uninterrupted (avichchhinnah). But those whose line or genealogy from the first ancestor is interrupted (vichchhinnapindáh, i.e., those who are subsequent to the fourth generation), shall have equal divisions. Those who have been living together shall redivide their property whether they had already divided their ancestral property before or they had received no such property at all. Of sons, he who brings the ancestral property to a prosperous condition shall also have a share of the profit.
