Wisconsin Statutes Marriage and Family (Ch. 765 to 770) § 765.23. Immaterial irregularities otherwise

No marriage hereafter contracted shall be void either by reason of the marriage license having been issued by a county clerk not having jurisdiction to issue the same; or by reason of any informality or irregularity of form in the application for the marriage license or in the marriage license itself, or the incompetency of the witnesses to such marriage; or because the marriage may have been solemnized more than 60 days after the date of the marriage license, if the marriage is in other respects lawful and is consummated with the full belief on the part of the persons so married, or either of them, that they have been lawfully joined in marriage. Where a marriage has been celebrated in one of the forms provided for in s. 765.16 (1m), and the parties thereto have immediately thereafter assumed the habit and repute of husband and wife, and having continued the same uninterruptedly thereafter for the period of one year, or until the death of either of them, it shall be deemed that a marriage license has been issued as required by ss. 765.05 to 765.24 and 767.803.
