Step 1: Understand the schools of Hindu Law.
Classical Hindu law on matters of succession and inheritance is divided into two main schools of thought: Mitakshara and Dayabhaga.
Step 2: Differentiate between the two schools.
Mitakshara School: Under this school, a son acquires an interest in the ancestral property by birth. It is followed in most of India.
Dayabhaga School: Under this school, a son does not acquire any interest by birth. The son's right arises for the first time on the death of his father.
Step 3: Identify the geographical prevalence of the Dayabhaga school.
The Dayabhaga school of law is followed primarily in the regions of Bengal and Assam, which correspond to East India. The rest of India predominantly follows the Mitakshara school.
