How can my spouse & I file divorce papers so that neither one of us individually initiated the action?

In Wisconsin this can be accomplished by filing a Joint Petition for Divorce. With a Joint Petition both parties will be required to sign the document and each will be designated as a Joint Petitioner. The paperwork will need to be filed with the Clerk of Courts in the county where either of you (or both) reside. To file a divorce action you must be a resident of the State of Wisconsin for 6 months and a resident of your county for 30 days before filing.
