Since my brother denied me any rights into my father's hereditary property after my father passed away, I filed a case in the High Court for getting my share of the property. My brother even denied me the access to all my important documents, contained in a briefcase which was in the safe custody of my father. He is now misusing those documents, including my bank cheque books to forge my signatures and depositing cheques in his name. These are bank accounts which have not been used for the last 10 years. My brother even may have gotten hold of some blank signed cheques which were returned by financial institutions whose loans I paid off and which were returned by registered mail to my father's address. Can he fill out those cheques in his own name? Is that a crime? Is it considered to be a case of theft of cheques and forgery. He has never shown any income on his income tax returns, so how could he have given any loan to me?
He is threatening to sue me by making up stories that he had given personal loans to me and my cheques are bouncing now. What can I do to protect myself?
