If a woman faces dowry harassment, she should act promptly to protect her safety and legal rights. She can report the matter to the nearest police station or file a complaint through the women's helpline or the appropriate women's commission. It is important to preserve evidence such as messages, emails, medical reports, photographs, bank records, or witness statements that support the allegations. She may also seek protection, maintenance, or residence orders under applicable laws if she is experiencing abuse. Consulting a qualified lawyer or contacting a legal aid service can help her understand the best course of action. If she is in immediate danger, she should contact the police or emergency services without delay.
