Do both parties in mutual need to be present @ final date

yes. because the six months is cooling period and on that hearing day you will have mediation and short evidence. the case will end. after that only the judgement date will be given.

both the parties should appear on the date given for the concent in the presence of judge and it is final 

without either party again court will give date so be present on that date and take the order 

you both need to appear together after six months of filing petition and again you will be called after another six months and thats the time the judgement would be pronounced

The answer is YES. Both parties need to be present on the final judgement date. Both parties have to sign the Court's original order in Judge's presence. The judgement paper is then tagged with an Exibit number. You get to read the judgement in Court, but you don't get an attested copy of it immediately. You have to apply for a copy by paying Court fees. In a matter of 15 days or so, the copy of Judgement is also available as a PDF document on https://court.mah.nic.in (this link is applicable to Maharashtra state only)

Hope this answers your question.
