Minnesota's child support program is a partnership between the counties and the state Child Support Division (CSD). The primary contact for dealing with your own child support case is your local county Child Support office. If you do not have that contact information, use the county office lookup available on the Department of Human Services (DHS) Public website. You can also send a message to your child support worker by logging on to MCSO and selecting the 'Case information' tab submenu link 'Messages'.
