This is complex...which makes it harder for the judge, I will frame things as I see them.
One...you really want dad to not have any visitation until he completes his counseling as (?) basically CPS recommended. MY understanding, which may be faulty, is he can or not do that...although I would assume a judge seeing that he has refused the counseling would wonder why/and or order it.
The deal is, with father petitioning the court...the court may revamp the past legal order and order a new one, based on what they see fit according to documentation and your representation. The point being, don't be too attached to the past status quo of you having sole legal over his visitation...even if the cps ordered counseling prior to visitation. A judge, based on fathers' testimony, or sincerity, or based on their mood, could order something different.
I am confused when you say father petitioned the court in August....where is the court date attached to the order? There should be a court date. If you do file a response, it needs to follow the legal guidelines for your state to be submitted before a certain period of time.
It sounds like your main case is dad not doing the counseling recommended, and your accusation he kidnapped child. I still dont quite get that...I understand your anquish.
I would focus on how and why dad did take the child from school and request repercussions should he do that again. Visitation guidelines need to be clear between both of you. If he violates the visitation order, then you can take him to court for contempt. But I would focus on appropriate visitation guidelines for both of you with child...and a specific request to the judge for sanctions should father ever scare you like that again.
One thing to get clear on, child support is separate...so far as I know anyway, in every state, from child custody issues. Given that fact...leave out any child support issues. Also leave out things like the past 11 years...while many may commiserate with you, a judge will not. You need to propose your case in the current present tense...that is what a judge will do...I would not talk beyond 2 years ago and only if applicable to your childs best interest RIGHT NOW.
Dad can bribe son...that will happen about anywhere...don't bring that up. You can spank the child...if brought up, what have you learned? It sounds like child is put in the middle...that means give the child some leway...if you are not concerned father is a day to day threat to child...then offer reasonable visitation to dad...otherwise the judge will order something you probably will not like.
I differ slightly on one recommendation here...I WOULD go ahead and file a response that is more lenient to the father child relationship. Awknowledge the importance of the relationship of BOTH parents to the son. Offer a reasonable schedule that you and son can live with that is not too disruptive from previous schedule.
AND, keep consistant on your requests being based on your need that father will complete the counseling by a certain date (court ordered), and that hallmarks are in place so that there are no "suprises" from dad.
It will go way farther in court...if the judge see's your change of heart and willingness he/she may be more willing to order some boundries for dad. I know its not what you want to hear, but the judge rules...and your prior legal status is exceptional...you dont have enough proof that dad should not be a viable part of childs life at this point.
If you do write another paper, focus on facts as to visitation that WORKED prior to the alleged 'kidnapping', and what worked afterwards...regarding your SON...no one else. The judge will hear that better than anything.
