Okla. Stat. tit. 43, § 43-117: Modification, suspension or termination of order for

income assignment.

A. Except as otherwise provided by subsection B of this

section, the person obligated to pay support or the person entitled

to the support may petition the district or administrative court to:

1. Modify, suspend, or terminate the order for income

assignment because of a modification, suspension, or termination of

the underlying order for support; or

2. Modify the amount of income to be withheld to reflect

payment in full of the delinquency by income assignment or

otherwise; or

3. Suspend the order for income assignment because of inability

to deliver income withheld to the person entitled to support

payments due to the failure of the person entitled to support to

provide a mailing address or other means of delivery.

B. If the income assignment has been initiated by the

Department of Human Services, the district court shall notify the

Department of Human Services prior to the termination, modification,

or suspension of the income assignment order.
