(1) The child support enforcement division (CSED) has developed a child support determination worksheet. Copies of this worksheet may be obtained from the Department of Public Health and Human Services, Child Support Enforcement Division, P.O. Box 202943, Helena, MT 59620 or any regional office.

(2) Included for use with the worksheet are a financial affidavit, necessary tables and information for completion of the guidelines calculation. To assure that these tables are current, the child support enforcement division will republish the worksheet with tables annually as soon as practical after release of information upon which tables are based. The worksheet with tables will be identified by the year of publication or republication.

(3) The child support guidelines worksheets, or a replica of those forms with a similar format and containing the same information, must be used in all child support determinations under the guidelines and a copy must be attached to the support order.
