State Legal Services Authority has mediation centre. Just go there with an application and submit it. They will give you a date. They will first send an ORDINARY post to your wife requesting her to appear for mediation. If she did not turn up on the said date, then they will send a REGISTERED post. If she refuses to receive the letter or did not appear for the mediation after receiving the letter, the mediators will advise you how to go about it.
Remember it is not binding on either party to appear before the mediation. It is on voluntary basis.
NO FEE is charged by the mediation center. But, while applying they will ask your annual income. If your annual income is less than Rs.75,000/- then you are offered free legal aid.
I have also applied for mediation though no cases were filed by either side. My lovely wife did not turn up.
I personally feel it is a waste of time. AFter submitting application, it has been more than 2 months. Nothing happened.
If you are ready to face anything instead of sitting in the dark, better approach the police commissioner as suggested by rajanjoshi. One of LCI members did the same and made his wife to appear in women police station for mediation.
