Courts in Mo always have power to change visitation, custody , support or issues that deal with the children. After the first order a joint agreement is best, cheapest and easiest on the emotions. That is not always something that can be arranged.
Either party may file a motion to modify stateing reasons and what they want changed. Then if matter can't be settled as you go along you will have a trial. You don't have to go to mediation and if you do , you don't have to agree to anything. I receive the ;mediator's report lots of times that simply says partied unable to agree. You need to see a lawyer and review the parenting plan and what you want to do and plan a strategy as to how you will handle the case.
Missouri courts always have the option of changing custody AFTER they have heard sufficient evidence of two things:
a) there has been a substantial and continuous change in circumstances with the children since the Judge last ruled on custody; AND
b) making a change in custody is in the children's best interests.
Your question starts off implying that dad is wanting to take you back to Court and that he wants to give mediation a try. St. Charles County is home to several top-notch mediators and, if the schedule should be changed or you agree with changing it, the mediator can help that process more affordably than two private attorneys. They do not represent anyone in the case -- they are there to help you two compromise.
You end your question stating that dad is a horrible father and a verbally abusive man. If there have been any changes in how he cares for the children and you feel the time is right to modify the visitation and/or custody provisions - you have a right to do so as well.
I also highly recommend that you hire a lawyer who practices regularly in the County where your custody order is on file. I wish you and your family the best of luck,
