After my wife's father gained heavenly abode, her brother wanted to gain control and possession of hereditary properties left behind by her father. When sanity did not prevail over him, inspite of repeated requests to be fair, my wife filed a property case in 2006. Subsequently, to harass my wife, her brother stole her very old chequebook in which no transactions had been done for over 10 years, the bank had made the account dormant in 2002. Her brother stole this chequebook from her late father's almirah. She had given some blank signed cheques to her father at the time of her marriage about 15 years ago, to settle her dues, since she was moving abroad. She forgot about the cheques for more than 10 years and the account became inactive in 2002 because of no activity and hardly any balance. Her brother stole these cheques after his father passed away and my wife filed a case for her share in property. He then filled the rest of the cheques, dated them for various dates in 2010, and tried to encash the cheques. The cheques were returned by the bank. He then threatened her to withdraw the property case, and when she did not agree, he filed a case under section 138, taking a stand that he had loaned this money to her in 2004 and taken post dated cheques for 2010. The entries in the cheques are not in my wife's handwriting. My wife never had a need to borrow money, with God's grace. He filed this case after my wife filed a property case. The bank account was already inactive in the year when he says he collected the cheques from my wife. He has not given any proof of loan in the court documents, only copies of cheques, where nothing except my wife's signatures from 10 years ago are genuine. Please advise
