The art and science of cross examination in 498a is the key for winning the case.
The right kind of questions will influence the judge in making a judgement regarding the credibility of the witness and to shake his/her credibility questions are to be crafted using the strategic values of these things..
Questions which shake the credibility of the witness.
Now if wife alleges some injury and there is no MLC related document on record then you have to ask if you have opted for MLC or done any formal complaint about incident. Here keep this thing in mind that you already know the answer will be a big “NO”. If somebody has done cruelty on wife oboviously the person would complain about the incident. beware you do not have to ask the question why she did not do the complaint rather give a suggestion that no incident happened that’s why you did not do complaint or told anybody. Now if she acts smarter and will try to add she did not do the complaint because she wanted to save the marraige if you ask why she did not do the complaint.
Questions which are directed to her in which you know there is no evidence on record
You know wife has no evidence of spending 25 lakh in a marriage you can ask questions like supporting bills or jewallary items like this
Have you attached any jwellary or marraige related bills? dont go to the question why you have not attached the bills.
Contradictory previous statement
You need to highlight the contradiction of 161 statement and examination in chief and content of complaint if there are material contradiction of date/place.
You need to put your defense to her you have to first identify her Facebook or WhatsApp number and then confront her with the messages exchanged
