I am a Mother who wants better rights over my son, can any one help?

You may want to post this in family law. And they will probably ask you for more information. Things like: your location, whether there is a custody order in place, what you are looking to gain. And probably some other stuff. Hope this helps a little.

What do you mean by "better rights"? What is your situation now?

To get any change in your custody/support/visitation situation you need to go to court to petition for a modification of the existing order.

What type of order do you have now, which court is over this ( state)

But you will have to go to court and get a change in your current order
