Completing the construction of a building inherited from one's father
Q: I am a lady. I have two brothers. My dad left a house which has 2 floors; ground floor and first floor. On the first floor, there are only pillars. The construction was going on but my father passed away. The house was on my father's name itself but he used to say that the ground floor will be for my eldest brother and the first floor will have two portion, one for me and one for my other brother. But since he has passed away, my brothers are telling me to do the construction all by my own and they will not help me in doing that construction. They are telling me that if I want, I can do the construction and live there. Is this right? Should I do the construction on my own or should they also help me?
