Hi I live in Utah my son dad has never seen him and still refuses to see him we had a dna test and he was proven to be his dad he has never bought anything for him can I file abandonment charges on him

I'd be less concerned about abandonment (which you can't do and which would be meaningless) and more concerned about filing for child support.

Or have you?

No you can't file for abandonment. What is it your really want?
