My father passed away last month and following his death. My mother took possession of my room as well as all his investments in the Bank, LIC, Post and gold etc of my father deliberately. In spite of being the only child, I was not shown any documents and they are in the sole custody of my mother. Even the succession certificate is applied for PPF without nomination. The amounts w.r.t my father’s investments have already been encashed by my mother. I want to file a case to recover the amounts from her. Kindly suggest me how to proceed.
