252E.6A  Motion to quash.
  1.  An obligor may move to quash the order to the employer under section 252E.4 by following the same procedures and alleging a mistake of a fact as provided in section 252D.31 or as provided in subsection 2. If the unit is enforcing an income withholding order and a medical support order simultaneously, any challenge to the income withholding order and medical support enforcement shall be filed and heard simultaneously.
  2.  The obligor may allege as a mistake of fact an error in the availability of dependent coverage under the health benefit plan because the coverage is not accessible to the dependent. Even if the plan is not accessible as defined in section 252E.1, the court may determine that the plan is substantially accessible if the obligee demonstrates that the dependent may receive a benefit under the plan. Section 252K.316 relating to evidence and procedure shall apply to the court proceeding.
  3.  The employer shall comply with the requirements of this chapter until the employer receives notice that a motion to quash has been granted, or that the unit has amended or terminated the national medical support notice.
