Not arbitrarily. The custodial parent would have to receive permission from the court for the change in residence.
You can't. One has nothing to do with the other.
no
Yes. Child support is for the "custodial parent". If you are not living at home with your custodial parent, then they are no longer eligible to receive child support. However, the non-custodial parent can request a modification if the child is no longer living with the custodial parent and that includes a change of custody. A 17 yr old is not emancipated in Texas, unless proper procedures through the courts have taken place. If that is the case, then the custodial parent and child are no longer eligible for child support.
If you are the custodial parent you can.
There is no such law.
Such issues are not the jurisdiction of the state's Attorney General. The custodial parent will need to file suit in the appropriate court in the city or county where they reside against the non custodial parent.
Technically arrears cannot be waived. However, a custodial parent can fill out a form stating that no child support is due.
Don't think so. The key word here is "custodial".

Yes, if it is so ordered in the child support agreement. If the parent loses their insurance and the custodial parent has the ability to insure the child - it will be possible for the state to order the custodial parent to do so. This may change the amount of support the non custodial parent pays - it is entirely up to the whim of the courts.
