how can i stop child support payments if the child is coming to live with me?

You can only safely stop making child support payments when the order requiring you to do so is changed. If the child is going to live with you, you need to change the custody and support orders, including perhaps having the other parent pay you child support. You need to review the situation with an experienced family law attorney to ensure the proper orders are prepared, filed, and signed by the court. I am available to assist you, if you so desire.
