498a who's responsibility to prove

Hi Experts

When wife files false 498a FIR then even you have enough proof to prove it false on lots of points but IO doesn’t consider them and said we mostly take woman's complaint and create charge sheet based on it and denied to  considering proofs?

Here lawyers says accused has burden to prove it false line by line as SC has ruling that whatever woman said is correct. In this case lot of imaginary content which somebody may or may not have proof.

How to proceed and way out ?

What is actual and what is myth please clear.

Please help Thanks
