i payd chaild suport 363 plus insurance 80 dollars. but after the court decision i change deffrent job .and my income is low , so what i can do

You could file a Motion to Modify the child support based on your job change.  The Office of Attorney General may be willing to do that for you, so try them first.  If they will not help, then you may need to hire an attorney to represent you.  In the meantime, you need to continue to pay at the rate ordered.  If it has only been a few months since the date of the order, you may not be able to get the support modified so soon after the order.
