My sister’s husband passed away tragically in an accident back in August 2012. Sadly, their only daughter also perished in the same incident. Since then, her husband’s relatives have been relentlessly pressuring my sister for money and the property that was in her husband’s name. My sister’s mother-in-law is still alive and living with her. This constant harassment has left my sister deeply distressed. I need advice on how she can navigate this difficult situation.
