I just checked Dickinson County in MI. In Iron Mountain (Dickinson County 41st Circuit court) a case (Case ID 2006-0000014336-DS) back in 2005 that concerned child support that was settled in 2006.
This second separate one might be of concern. There was an additional civil case from 2015 (Case No. 2015-0000018432-DS) involving support/custody of a child. It appears she initiated court action and
it involved different a man than the 2005 case that was closed. A motion was then filed in 2021 to amend custody. A motion and order to show cause for contempt was filed in August 2022 and there continued to be motions/orders and hearings related to that case included a failure to appear, with the last court record dated April of 2024 for a "Show Cause Hearing". To view the somewhat lengthy records pertaining to this child support/custody issue click on the box titled "EVENTS" in the court records, then scroll down to read them all. It does show as "closed" but no telling what the relationship is between the parties involved after that many years of lawyers and hearings.
Records are at the States MICourt case search.
