I have not heard from my son's father since mid-April, over six months ago. I do not expect him to contact me any time soon. I do not believe that he is doing well emotionally or financially and I understand he is not living his life responsibly. He has never paid child support as there has never been a court order for him to do so. We were never married. There is no custody agreement in place and as I understand, that gives me custody by default in Arizona. I would like to have his rights revoked, but he is listed on my son's birth certificate. Am I able to do that in my county? And if I do, does that mean there can never be an order for child support? What are the steps I need to take in order to start the process and what is the likelihood that it would be granted? Would laws of child abandonment apply to my situation?
