yes, after one year either party can request that the separation be converted into a divorce. If your spouse filed a motion to do so with the court and it's been a year, the court is compelled to do so.
"By stipulation of both parties, or upon motion of either party not earlier than one year after entry of a judgment of legal separation, the court shall convert the judgment to a judgment of divorce."
(Wis. Stats 767.35(5))
