If there are no injuries and medical reports attached then there is no conviction.
Also in India conviction rate is as low as 2%. Most of the cases end in compromise either by divorce or monetary settlement.
Cases run 2 to 3 yrs depends on pendency.
Recently my friend got acquittal from 498a and divorce is almost close. They r going for settlement for 5 Lakhs.
Initial demand was 20 laks, since my friend won 498a, they came down to 5 lakhs.
In any case it is difficult to proove beyond reasonable doubt that husband harrassed wife.
Until and unless there injuries to wife and medical reports available and incident reported on the same day and neighbours as witness, then only conviction possible.
So don't worry much on 498a if there are no injuries to her.
Most of the time nealy 2 Yrs Judges will not take up cases and gives time for settlement.
Almost all 99.99%, once 498a is filed it is end of married life. Wife cannot force husband to come and listen to her by filing false cases.
So don't worry.
