1. Now my passport is in the court. How should I get the Passport back?
File an application for release of passport and if the court satisfies that you will not run away from the clutches of law, it will release with some conditions or refuse to hand it over to you. If you aggrieve with the court order, then you can approach appellate court.
2. What is the procedure for removing LOC and how long does it take?
File an application to the police to remove LOC, showing the bail order. If the police say that LOC is issued on the basis of court order, then you have to move the court to cancel LOC against you. Again, if not get relief from the court, has to approach the LOC
3. I'm planning to file RCR, will that be useful in Divorce case?
Not much. If she filed divorce, then try to go for mutual consent divorce.
4. when i speak to poilce about removing my parents name, they said under dp act they can't remove their name. if the guy is major, does it still apply on parents name? as I dont want their name to include.
To remove the parents' name from FIR, you can approach HC under S.482 arguing that they have no role to play in matrimonial issues between the estranged spouses.
My parents they never stayed along with me.
That is one favourable ground for you. But DP relates to demand of dowry during the marriage ceremony.
