if the person is paying 100% Home Loan EMI, then he can claim entire property. In this case, person B decided Buying a Joint Property with Parents. He took a home loan and was paying 100% EMI. After some time, the differences cropped up between person B and his parents. His parents decided to inherit their share in the property of person B to their daughter because of disagreements with son i.e. person B. Person B challenged the WILL of his parents, and the court ruled for parents. Therefore just because i am paying the EMI of the property does not mean that i own the share of my parents in the property.
