Restitution of conjugal rights (RCR) is a civil case. It is a legal way of showing your interest in getting your wife back.
If she files a false 498a, RCR helps in the ways mentioned below.
1) Reduces maintenance and alimony
2) Weakens her 498a
3) Fast tracks divorce
Normally, a wife will not come back once you have filed RCR. If she does,
it'll only be to fabricate evidence against you,
the downside of RCR is that it increases the risk of a false 498a against you. So file an RCR if you are sure that she's anyway going to file a false 498a against you.
and if husband who has 498A proceedings on his head, still wants to rehabilitate his beloved wife with him, he gets ample oportunity to do the same during CAW cell meetings.
