Az Divorce Records

How I can find AZ, CA, SA online public records?
I am trying to find my biological father. I have some information in it (information on my birth certificate). I did a little research on Google, etc, and I think it is in Arizona, but I do not know for true. I know there are all kinds of public information, but do not know where to start or even what it would be useful for me. I want to find registration information voting, marriage or divorce information .. free public information. Suggestions? Please?
