I came across a similar case but the guy had won the DV case against his wife. Yet she barged into his house without any order at hand. The guy tried to file a complaint in the police station, but the police would not take as they were under pressure from mahila sangams. He went to ACP, DCP, CP but no relief.
Finally, we suggested he approach Human Rights commission. That did the trick. The human rights commission gave an immideate direction to the cops to lodge a complaint and take the necessary action against the tresspassing wife!
So if all else fails, do approach the Human Rights commission. The above is just for your information.
