You may want a lawyer, but you can go to court on your own. Someone from the IV-D Unit may come to the hearing and ask for the change in child support. But the IV-D Unit does not represent either parent.
You need forms. You can ask for them at your court. There might be a fee. There are ways to get them online too.
You can find the papers you need on the court’s website at: www.mncourts.gov.
Make sure you read the instructions, so you know what forms you need. To avoid problems, right click on the form link and choose the “save as” command to download it to your computer.
Note: Medical support can be reviewed anytime if the child’s available insurance changes. It can also be reviewed if one of the parents or the child has a change to their eligibility for health insurance.
