You can still remarry but you will still owe the child support arrears.
what if your done with current child support but still owe interest for back support.
Yes.
Not from that moment but you still owe if you owed prior to the signing away. Someone else paid for your child and should get their money back.

You still owe the back support. Once the child reaches the age of majority (as defined by the support order) there will be no continuing obligation.

yup
You still owe the other parent money and they have to be paid.
Yes - the arrears are still due - the child support order ends when parental rights are terminated.
Yes. You must pay until the child support order has been terminated by the time set forth in the order, or terminated by the court. Even if the order is terminated you will still owe any arrearages.
How does a 23 year old get adopted? They are already adults. The back child support was until she was 18 (Perhaps until out of college). If you didn't pay it then, you still owe it. What happens since then doesn't eliminate your debt.
