Legal Question in Family Law in Utah

Without any lectures, it would be helpful if I knew the nature of your custody order. If you and your ex have joint legal custody, then this would be an issue which the two of you should address and decide on based on your Parenting Plan, including the dispute resolution provisions in the plan. If your ex has sole custody of the children, then the decision to put braces on the kids would be hers. As it pertains to the cost, orthodontics are generally considered by the courts to be a reasonable mediical/dental expense to be shared by the parents. If this is something you're truly willing to go to court over, you may want to take the children to another orthodontist and get a second opinion as to whether the braces are reasonably necessary.

Looking to the Orders of the Court is necessary. You may also look to why you are paying 25% extra in child support. Does the reason still exist? Is there a material change that would allow to drop the 25%? You may have to share in the cost as stated, but you may look to whether you can change the 25%. You may not be able to, but if you truly willing to go to court over the orthodontics issue, you may as well look at all of the issues.
