Let me first say Congratulations on getting your son. I know how much time you lost with them for a while. I’m so glad for you [:)]
If she sincerely has no issue with signing the agreement, could you take it to her and have her sign it? If she is having any type of visitation with your son, could you not take the paperwork with you and arrange someone to notarize? I know that you are out of state but this sounds like you need to “take matters into your own hands” so to speak and make sure it gets done. Maybe she’s not stalling to keep the child support payments, but this way you would know for sure…would she be required to pay you back any money over since June in this?
I don’t know about sending the papers through without her signature. It would seem that possibly the judge would want to call a hearing and require her to be there to agree or would tell you to get them signed and then come back…Maybe the attorney will respond soon.
