If the reason that you haven't seen him is because the mother has kept him from you, you can likely get some kind of visitation. The process likely will be very slow starting out with supervised visitation and moving on to more frequent and longer visitations without supervision.
In order to get the process moving you should hire a good family law attorney. Your attorney will draft a petition for visitation with your son and file it with the court. Some steps might need to be taken to track down your ex. However, the child support agency will likely have her address.
You do have rights to visit your son, but the court is going to want to know why you waited 10 years to exercise them. The fact that you have paid child support will help your case.
