Indian law criminalises the actions of cruelty and death resulting from dowry demands. This is known as dowry death. If the death of the wife was because of harassment for dowry demands, the husband and the in-laws of the woman can be punished.
In cases of cruelty and harassment, you can approach the police station and report this crime by filing an FIR.
If convicted, the husband and her in-laws will be punished with jail time between 7 years and life imprisonment.
