1. Firstly, if both of you agree to take divorce, then it is called as Mutual Consent Divorce. For this, you have to present a joint petition stating that you want to get separated through mutual consent divorce. This is called as the First Motion. Then you will be given a 6 month cooling period during which according to the courts you may rethink and take back your petition. Then after 6 months if you still insist on taking divorce then the court asks you to file an affidavit and grants you the divorce decree. This cooling period may be reduced under certain emergent situations in the discretion of the court.
2. If your wife files a divorce petition in your absence, then if you do not represent the case in any way, then she may be granted an exparte divorce decree and also for maintenance if she also claims from you.
3. If you file for divorce and go abroad not representing it any further for a longer time, then again the case may be decided in your wife's favour in your absence.
