Do sisters have share in the house constructed by brother and father

My father in law and my husband jointly constructed a house in my father in law's ancestral property. My husband has shared 60% of the cost of construction. Now to transfer the house in my husband's name his 2 married sisters are asking money as settlement and my father in law is also telling to give some amount to the daughters. But my husband has given money for their marriage also. Should my husband have to give money to his sisters? do they have legal rights in the property? We are hindu family living in a small town in Tamilnadu.
