Minnesota's child support program is a partnership between the counties and the state Child Support Division (CSD). Employers should contact county child support agencies with questions regarding a notice you received or case-specific questions. If you do not have that contact information, use the county office lookup available on the Department of Human Services (DHS) Public website.
