What do I need to do to file a motion to dismiss child support that will be uncontested by the other parent?

I have been primary custodial parent for the last 5 years with the other parent only taking the minor child for 2 overnight stays per week. The other parent has agreed to terminate the original child support order. I received a motion from the clerk, but upon return was told since it was uncontested that I needed another motion. What law form do I use? Is a financial affidavit required by both parents with the motion?
