Subject to par. (b), the department may terminate child and spousal support enforcement services if there is no longer a current support or maintenance order and either of the following applies: 1.
(1)#
Any support or maintenance arrearages total less than $500.
(2)#
Any support or maintenance arrearages are considered unenforceable by a county child support agency under s. 59.53 (5) because no support or maintenance payments have been collected for 3 years and all administrative and legal remedies for collection of arrearages have been attempted or are determined to be ineffective because the payer is unable to pay, the payer has no known income or assets, and there is no reasonable prospect that the payer will be able to pay in the foreseeable future.
