This is a fit case for perjury. She has evidently played fraud on court, she can betaken to task. There are plenty of such examples where court has taken action against such fraudsters.Recently in Pune family court there was a perjury case on the same lines.The details are given below for your information:
Family court orders FIR against software engineer who lied under oath of being a homemaker to secure maintenance from husband In a rare order that could have a bearing on hundreds of cases related to marital dispute, a 33-yearold software engineer from the city's Maharshi Nagar area — who lied under oath to receive maintenance from her estranged husband — will have to face a major penalty for 'perjury'. Pune family court judge P L Palshingkar ordered the court administration to file an FIR against her recently. For, despite earning more than Rs 9 lakh per annum, she had informed the court that she was a homemaker and, therefore, liable to get alimony. The court had earlier ordered the husband to pay her Rs 8,000 per month as alimony. When the husband (37), who is also a techie, came to know about it, he complained to the court with evidences like her salary slip and CTC figure. Palshingkar noted that there was enough evidence against the woman to prosecute her and directed the court's deputy registrar to file a complaint under sections 191 and 193 of the IPC for concealing her monthly income even as she sought maintenance from her husband. If convicted, she faces a jail term of up to three years, apart from a fine.
Can I file a case against her for perjury and get her punished for lying under oath, as I have documentary evidence to prove that she is lying about her income and misleading the court to order interim maintenance in her favor. The court has not yet held any hearing on her interim maintenace application.
You can very well file a perjury case against her,but you may wait until she deposes evidence on oath before court after which she cannot escape.
