Let me explain-
JMFC- Judicial Magistrate First Class
RCR- Restitution of Conjugal Rights.
I can understand the confusions of a layman in the matter of law and procedure of the court particularly if you are handling your cases all alone. Ask your previous lawyer to give you a little time and guide you a little bit and show him the draft before submitting in the court so that he can make the necessary corrections.
If it is an interim order of maintainance u/s. 125 crpc passed by the JMFC, then you will have to file a revision petition against the order within 90 days from the date of the order u/s. 397 of the crpc in the Sessions Court ( Again I repeat it should be filed in the Thane Sessions Court and not Bombay High Court ).
I hope this info wud help you.
