Question: Can you accept inheritance wealth from someone whose income was predominantly earned through Haram (forbidden) means?

When wealth is passed down as inheritance, the inheritor is not directly responsible for how it was earned. The act of receiving inheritance is lawful (Halal), as the wealth changes ownership through a legitimate means (inheritance) as per Islamic law.

Islam does not require an inheritor to investigate or delve into the precise origins of the wealth. As long as the wealth comes to you lawfully (e.g., through inheritance), you are not responsible for the sins of the deceased related to how they earned their wealth. Your accountability begins with how you use that wealth moving forward.
