OHIO Part 38

In divorce actions, however, the rules for personal jurisdiction are a bit different: a court can have jurisdiction over a divorce based upon the contacts that the plaintiff-spouse has with the state and regardless of the defendant-spouse's contacts. For example, if you were married in Ohio and later moved to Tennessee where you now permanently live, but your spouse later moved to Nevada, you could file a divorce action in Tennessee.

However, the personal jurisdiction rules change a bit again when alimony is being requested in a divorce action.
