Unfortunately, yes, almost certainly. The state's (and the court's) concern is with the "best interest of the child" and it still operates off the notion that the best interest of the child includes two parents including the duty of providing support.
However, it does not mean that he will automatically get full visitation, etc. Normally in cases like this there is an extended period of time, often supervised by a neutral party, in which the child can get to know him before he is allowed to have access like a parent who has been there all along.
The court will look at all factors, including whether he tried to have any contact over the years, etc, in determining how to structure the visitation plus he will have to start paying child support and if the child received any public assistance over the years the state will likely go after him for that as well.
In addition, many times the fathers don't actually exercise visitation after this long. They may go through the court proceedings and be awarded visitation privileges of some type but then they fade out of the picture again other than paying the child support.
Please ask any follow up questions that you have in this thread.
