Does an Iowa court have jurisdiction over mn resident

That depends.  Although you never lived in Iowa, you may stil have sufficient contacts with it to allow it to exercise jurisdiction over you without violating your constitutional rights.  For example, are you being sued over a contract which was to be performed, at least in part, in Iowa, or over an accident which occurred in Iowa?  If so, the Iowa courts would almost certainly have jurisdiction over you.  Are you being sued over a contract which required you to ship goods to Iowa?  Did you advertise to Iowa residents in connection with the dealings to which the lawsuit relates?  Do you derive substantial income from Iowa residents?  Did you negotiate and/or sign the contract while visiting Iowa?  Do you own real property in Iowa?  Do you work in Iowa?   You can't determine whether the Minnesota court would have jurisdiction over you without analyzing these factors, and the issue is not always black and white.  If there is any question that Iowa might have jurisdiction over you, you can't take the chance of ignoring the lawsuit.  However, in most jurisdictions you can make what is known as a "limited appearance" to challenge jurisdiction, and you can also make a motion to dismiss the case based on either a lack of jurisdiction or because it is an inconvenient forum (in which case you would have to show that the forum is inconvenient for almost everybody involved, parties and witnesses, and not just yourself.)
