So my mom received notification that my biological father had died. They were never together, he was never on my birth certificate. I don't believe he was paying child support. So why? I don't remember who the letter was sent by, since I was 12 at the time, but it was government and official

This is in the UK btw, thanks.

It is true he died, I have the death certificate and I'm in contact with his family.

My mom has always said he was a bad person, and never told me anything else. His children, who he raised until he died, say the opposite. I'm fearing the worst and that perhaps she was raped and I was the result? He knew about me, but didn't tell his family, not even his partner of 12 years.

I don't believe there was a will, he took his own life in his early 30s. I'm now 24.
