Back child support, over 150 thousand, he passed away April 15th. He lived in Winnebago county. His name is Terry Aldershof, his wife's name is Sandra

Back support has to come through his estate.   If an estate has been opened - check the county where he passed - then you file your petition in that estate.  If an estate has not been filed, then you will probably have to open one.  You could also check with the IV-D child support office in the county where your order is and see if they can help you. He may have his child(ren) listed as beneficiaries on life insurance or his 401(k), both of which pass outside the estate.  However you may need the estate process to be able to determine if those accounts even exist.     Good luck!
