1. U/s 125 CrPC a lady asks for maint. pendentelite main Application and it is called Interim maint. in layman's way thus while main Application is being decided for finality she is seeking money to maintain her.
2. Thus step 4 is rightly mentioned in simple way. Once interim maint. (step 4) is awarded rest and other steps are followed. In rare cases a lady only asks for final maint. based on strength of her pleadings thus in such case(s) step 4 is omitted.
3. BTW it is also not necessary to follow all the procedures if prime facie a genuine case before Court. All the Court can do is to "record" her statement under Oath and even dispense with pre step 4 and post step 4 procedures however same are documented in Order sheets.
Kindly follow first Step 1 and or if you have time just go to concerned Court and watch the days proceedings to gain confidence and some tips you will observe by observing the Court proceedings un-called for (means your name is not there in the cause list yet you are observing the court proceedings without disturbing the Court), so shall you follow this practical or have another que. after thanking again !! :-)
