Mitakshara school divides property into two classes,viz:
1) Unobstructed heritage:- Property in which a person acquires an interest by birth is called unobstructed heritage. It is so called because the accrual of the right to such property has no obstruction. Thus property inherited by a hindu from his father,father's father,or father's father's father, is unobstructed heritage. Their right to such property arises from mere fact of their birth in the family and as soon as they are born,they become coparceners of such property along with their paternal ancestor. Ancestral property is therefore is unobstructed heritage.
