Can a father limit the share of one of his sons from ancestral business which was developed by him

My father opened a business with the money from his father. We are 3 sons, he educated all. I was the first, till education I was helping his business. After education, I joined a company and thereafter completely out of business. My 2 other brothers also educated, but they joined my father and developed the business. For the last 20 years, my father started taking rest and just giving supports, only my 2 brothers carried on the business activities. He took lot of loans to develop the business
