If a man is being falsely accused of domestic violence then the utmost important step he should take is to gather all the required and relevant evidence to prove his innocence. Evidence plays an important role here. A man can’t counter his wife if he doesn’t have all the relevant evidence.
And when he would be found not guilty then he can also file a countercase against his wife. According to the law, If a person is registered under a false case of dowry and or domestic violence then he can simply file a counter case on his wife with all the required and relevant pieces of evidence he has with him or can gather as soon as possible.
