Sister sold our joint property in Mumbai without informing me, what can I do?

I'm devastated. My sister sold our joint ancestral property in Mumbai last month without my consent. We inherited it from our parents, and I just found out through a friend that it was sold. I tried talking to her but she refuses to discuss anything with me. The buyer is already moving in. I feel betrayed and don’t know what my legal rights are. Can I challenge the sale or claim my share of the proceeds in Maharashtra court?
