My son is 17 - his father has just come into the picture - he was no where to be found. Can I get child support at this point?

My son will be 18 in July. He was born in Oklahoma but we now live in Ohio. His father lives in Colorado. His father was not on the birth certificate and has never been court ordered to pay child support. Is it possible to go to court and get this established? - Is this your question?
