My question involves child support in the State of: az

Long story short, I married my daughters mother in 2008 when our daughter was 2. We went into the Department of child support to terminate the child support and went on with our lives. Today we are still happily married.

We recently Built a home and I am now trying to switch from the construction loan to the permanant loan. The bank noticed that on my credit report it still showed I owe child support to my CURRENT WIFE. I went into the child support offices and they told me that it closed in 2008 (as it should have) and that I need to fix it in the courts. I went to my local court house and they told me that it is the Department of child supports issue. They keep passing the buck off on each other and I am getting nowhere, having been to both places many times talking to many different people about it. I dont know where to turn. I really cant afford a lawyer, all my funds are tied up in our new home. If anyone has any ideas for me, I would be forever grateful.
