Did your mother died intestate(without writing a WILL)? Are there other siblings to you apart from this sister? Is your father alive? On your mother's death, you will get equal share in your mother's share of the property in addition to your own share and the sister who is staying in Navi Mumbai will get equal share in your mother's share of the property. In other words, you are entitled to 75% share of the sale proceeds and your sister who is staying in Navi Mumbai is entitled to 25% share. Convince your sister that you want to sell the Navi Mumbai property and would like to buy an apartment in Bangalore, since you stay in Bangalore and you would be paying her 25% of the sale proceeds and let her agree for vacating the property. If she refuses to vacate the house ,inspite of paying her share, tell her that you would take legal action to evict her from the premises
