A: There is certainly a chance she will be able to enforce the unpaid child support. In Utah, child support is determined by statute, not by agreement, and the child support obligation is based on the current order of a court. If you have not modified the order based on reduced income or change in circumstances, then the originally ordered amount still applies. Additionally, unpaid child support can be pursued even after a minor child becomes an adult. She could potentially pursue the unpaid amount either through ORS or by filing an order to show cause with the court, requesting to reduce all unpaid amounts to judgment.
A: Any time you face criminal charges, you should be very active in protecting your rights and defending the charges. You do not have to be 21 to face adult criminal charges. 18 years old is considered an adult and you can be charged with contributing to delinquency before age 21. You should speak to an attorney to determine whether the charges are viable and if you have an effective way to defend or respond to the charges.
A: There are two basic options in terminating parental rights. First, you could try for a voluntary termination of his parental rights and he can sign away his parental rights. This is the fastest, easiest, and simplest way to terminate parental rights. The other way is involuntary termination of parental rights. If you are interested in this, you need to show that he has either abandoned the child, abused or neglected the child, and a few other options. From what you have said, it sounds like you have a good case to show abandonment. Of course, I would recommend consulting with an attorney if you want to seriously pursue involuntary termination.
