Filing section 340 crpc perjury case against wife

Dear all. Please advice My wife filed section 125 crpc case claiming maintenance and made all kinds of false allegations. For 3-5 allegations she made are false and i have enough evidence to disapprove it. Section 125 is filled in Bhavnagar and I reside at Chennai. We both resided together at chennai. Please advice in which court should I file the case for perjury. My first hearing is scheduled on 9th February, Should I respond to the maintenance case and file perjury case alongside in Bhavnagar court? Or would I have to wait for the maintenance case to get disposed of? Can I also file writ petition for speedy trial of the maintenance case? Regards
