specific to your questions about marriage expenses and compensation of cruel marriage:
1. there is no compensation to any party even if cruelty is proved… if it is criminal they could be punished or fined. The IPC 498a for cruelty on woman ends in less than 1% conviction. There is no compensation in that either.
2. marriage expenses: there is no law or judgment where it has been returned to either party. REad HC judgment below:
if you know of any judgment otherwise, let me know
