Ts, go to govt hospital first for gathering solid evidence

Private? Get govt if can, the most solid evidence can use in court

After pdrm report, then go to JPN for filling first
Then JPN will look at the case.
Most likely will start counselling first.
If case and evidence are strong, jpn can recommend divorce, very useful in Court

This, Malaysia has free lawyers from govt for those can't afford.

TS, you need to search

TS, ur sis can possibly get half if his epf when divorce
Just if ur sis really want to do it la.

Hope everything goes smooth for your sis, TS.

Please update status if you want to, I'm sure there are some pro here willing to give some words.

ALL THE BEST TO YOUR SISTER
