I have a daughter that just turned three. Her father is 5,000 in the hole with childsupport, hasn't seen her or even tried making contact with me for over a year. When she was first born he maybe saw her for a total or 20 days in her 3 years of life. He has 2 bench warrants out for his arrest. My question is I would like to change her last name to mine before she starts preschool. What are the laws on child abandonment and how can I send him papers when I don't even know where he is living?
