Can you please advise what should be my next step -
1. File a RCR ? and then go for a divorce with mutual consent, if possible ?
It is not advisable to file a RCR case for any reason.
If she has clearly indicated that she is not willing to live with you anymore there is no point in filing the restitution of conjugal rights case.
Even if the court decrees the case in your favor you cannot compel your unwilling wife to live with you.
Therefore you may better go for divorce case directly, fist ask her if she agrees for filing divorce on the grounds of mutual consent, if she declines the offer then you may file contested divorce case on the grounds of cruelty and desertion.
2. In my case how should a RCR be drafted to be impactful with no loop-holes?
If you are interested i filing RCR only then you may contact a local advocate who will help you draft the petition and file the case.
3. Should the settlement be done before we file a mutual divorce or later?
The settlement, as per negotiations and the agreement thereon, can be settled accordingly, there is no hard and fast rules about this.
4. What points should be considered and articulated for a mutual divorce(if possible) so that there is no issue in future?
The points that are to be taken care of shall be:
the one time setlement amount and mode of payment including number of installments;
exchange of each other's articles;
the custody of child with whom and who will bear the expenses for child's education and future well being etc., ;
Visitation rights of child if custody is with her;
Any other issue of concern including an undertaking that nobody will sue each other in future once this marriage is dissolved by a decree of divorce.
