I recently filled for guardianship of my niece who is 17. Her mother was killed 5 years ago in a car accident. Her biological father (my brother~whom I have not contact with) signed over all parental rights after my sister-in-laws death to the step father. Then the step dad adopted the kids. Now her step father has signed over guardianship to me. Can I get child support from either of them? I don't know if the state has a open case of unpaid child support from my brother or not but 12+ years he did not pay! Now her step dad doesn't either? I am not currently able to afford an attorney to fight for child support but I did the guardianship on my own and did well I might add. She also has a problem with her lastname. Her social security card and check for her mothers death has her maiden name, when she went to get her id they made her put her adopted name, but when I filled for guardianship they made me put both. What is her real name supposed to be and or how do we change it? What should I enroll her in at school and she is applying for jobs what should we do?
