Dear Client,
Thank you for your inputs regarding your case. Based on your circumstances, it is possible to quash an FIR or charges under Section 498A and related IPC provisions under Section 482 of the CrPC if certain conditions are fulfilled. Given that this is stretching further without any valuable progress, you can try moving a petition for quashing in the High Court. However, it has generally been held by the court that in cases not featuring mutual consent for settlement, quashing will only take place if such allegations are shown not to suffer from merit or substance.
If you stay as separated individuals with your wife in peace and in consent to terminate the matter conditionally, you could approach the court to file a joint affidavit stating that you have no intention of proceeding with the case. Should the wife disagree, you could seek to quash it individually and illustrate how the case has turned into some kind of folly in pursuit of revenge or inaction, leading to abuse of process. Plus, an additional supportive submission showing no material trial progress would only help.
The quashing goes on from few months even up to a year, taking their time dependent on the backlog of each High Court. It is very important to get an experienced criminal lawyer to help you for best representation. The legal fees for a quashing petition may cost you from ₹50,000 to ₹1,50,000, depending on each case's complexity and stature.
I hope this helps. Do feel free to get into contact for further assistance or questions.
