My child support arrears not including interest. How do ever put this debt away so I can live a normal life and support my children?

How do ever put this debt away
No way.Even if you file for bankruptcy that debt will remain intact.

How did you get deep in arrears in the first place?

By getting a second job and living on a tight budget until it is paid off.

And what do you mean, have a normal life with your children?

What is your WHOLE situation?
