That's great that the two of you are able to get along now for the sake of your son. I'm glad things are going well.
I have a suggestion for you. Go to the courthouse and ask for a CS order change motion packet. That's probably not what it's called, but there is a standard form you can use to file a motion to change the existing CS order. One part will have a box to check regarding the reason for your change request. Tell them that you are requesting the change because of a change in parenting time. You may have to get the custody order changed, if you haven't already done so. If that's the case, they have a form for that too.
If you have to file a motion to change custody, and there isn't room to put all the details of your agreement, just attach an extra piece of paper and put "see attached" on the form. If you are in agreement, it should be pretty simple. She wouldn't even have to appear in court if you can get her to sign it ahead of time. The judge may order a change in CS with the custody order, or you may have to go to the CS magistrate. If you go to the CS magistrate you want her to appear to tell them you are in agreement.
The problem with this is...If you are agreeing on joint custody, the judge may not go along with it if you have been in there a lot in the past with problems. They don't want to give out joint custody unless they trust you to get along.
I hope it works out for you.
