I am going through a divorce, and would like to know if I legally have any rights or way to see or even just to talk to my ( yr old son. (non- biological). I have raised him since he was one. Any information you could offer would be a huge help.

You could seek visitation as a significant influence in the child's life for the last 8 years.

Many courts will allow it if there is an absent father. And child support will be ordered.

... if I legally have any rights or way to see or even just to talk to my ( yr old son. (non- biological). ...

Assuming you didn't adopt him, technically he would be, after the divorce, you ex-step-son. Normally, one does not have any legal rights with respect to a step-child. But yes, as others have indicated, if you ask for visitation you might be awarded it.

I don't know the law of your State.
And.. I don't know if his biological Father plays any part in his life (which might be influencel).
All you can do, is to try.
Get a good, reputable, attorney - and see what can be done.
A Judge, in a Court of Law, would make the decision... a lot of factors would make the determination.
If you want this, do not let much time lapse - if you do, the legal folks may wonder why.
Has his Mother refused you ? You need to know her reasons for doing so.
You have a chance.. but it needs to be legal .
