How much longer do I have to pay support?

There are no cost of living increases in child support. Seeing your son has nothing to do with paying support. You have to pay until he turns 18 or graduates from high school. If the court ordered her not to home school and she is doing so and you can show this is harmful to the child, you need to make a motion for contempt with a clear cut order to enroll the child in school withing 3 days of the date of the order. Motions for contempt often fail because they are not well done and fail to actually make an argument showing contempt. The fact that she lives with her parents or another man is really irrelevant.

You have to pay support until your child reaches legal age, which is 19 in Nebraska. You are going to have to go to Court if she has sued you for an increase in support so you should file Motion relative to seeing your child.

Since you are having to back to court anyway you might as well file a motion to enforce and get attorney fees when you prove her violations. Child support is payable until the child reaches 18 years or graduates (which ever is later).

I don't know. Have you used an attorney for the contempt motions? Did you file them timely? Did the attorney explain why you lost? Regardless, in Idaho child support is due until the later of the child turning 18, graduating high school or turns 19.
