It is not easy to modify a parenting plan, the court do not like to do that. This would be a major modification and he would have to show the court an an initial threshold hearing that there is adequate cause to modify the parenting plan due to a substantial change in circumstances that is now harming the children. I would wait and see. If he is not already in compliance with the current plan you can move for contempt. Child support is separate but would be included in any action brought.
Your instinct is correct, you are able to make those decisions yourself as you expect him to. He can try to make an issue out of this but I do not believe he would prevail if he brought dispute resolution or court action.
are you going to the hearing? Why do you think she will be awarded that? Prepare with detailed financials and make sure they are filed with the court with copies to Family Law. If you do not get the outcome you think is just you can move to revise the Commissioners ruling or have the same Commissioner Reconsider his or her ruling.
Are you it the process of a divorce? Is there a temporary parenting plan? If not that is what you need to establish. It is done by making a motion.

All property is before the court in a dissolution of marriage, community and separate. In a short term marriage the court is to put the parties in the position they were in before the marriage, typically parties have not been together long enough to significantly grow community assets. Inheritances are characterized as your separate property. You should review all of this with an experienced family law attorney. The sooner you file and separate the stronger your case is for separate property.
That is going to be hard as she is the custodial parent and I assume has decision making authority when the children are in her care. I would document your concern in a written communication and then advise her you can only afford 75% of reasonable uninsured health care expenses and in network providers. If you push it and risk violating the final orders she can bring you to court and you would be heard then. And also risk losing. Or you can invoke your dispute resolution process.
She can take you to court but the question is would she win. An attorney
should review the language in the final order of child support. This state
wants parents to contribute to college if they can so hopefully your order
is very clear. Sara Tamblyn, www.tamblynlaw.com
