The Wisconsin maintenance (alimony) law was recently changed.   2013 WI Act 209 states that maintenance ends upon the recipient’s remarriage.   The law also requires the recipient to notify the court and the payer of the remarriage.  The law can be  found at https://docs.legis.wisconsin.gov/2013/related/acts/209.   This law seems common sense, but previously, the payee was not required by law to notify the former spouse of remarriage.  The burden is now on the person receiving maintenance to make that notification.  This law does not, however, apply to divorce judgments entered prior to its enactment.
