My question involves paternity law for the State of: Illinois
I will try to make this quick but get all details in.
I am from Iowa, moved to Chicago after college for my first job. Met a man and we became pregnant. I had her in Illinois and lived with him for a short time until I decided moving back to Iowa was safer etc. We continued our relationship for another 9 years and had a son. The distance eventually caused us to split ways. We were never married and he never signed the birth certificates. But I trusted him and he was a good dad and supported them for 13 years. Daughter is now 13, son is 10. July 21, 2018 he lost control of his motorcycle and was run over by and SUV and was killed. His family is not settling the estate properly (but that is another issue). Since he was not on the birth certificates we are having an issue with filing for Social Security benefits for the kids and for inheritance since he was not married.
I have TONS of circumstantial evidence proving he excepted them as his children. Photos, posts on facebook by him, introduced them to everyone in his life as his kids. Text them almost everyday saying things like "don't forget about dad". When I named them I gave them my last name but his last name as a second middle name. His family named my children in the obituary and in the fathers obituary back in 2015. He deposited money in my account every week for support (not court ordered, not through a government agency) The family is not willing to help because they are trying to scam (or something shady) the estate and keep things for themselves. I've gotten death threats and very very horrible harassing text messages from them.
Is there a form I can fill out and send in with information I have to see if "the courts" will legally name him as their father? Or do I need a lawyer? Will they exhume him for DNA?
