Nunc pro tunc

(nunk proh tuhnk) Latin for "now for then," meaning to cause an order or judgment to apply to an earlier date. Example: A divorce judgment is submitted to the court but, because of a mistake of the court clerk, not filed or signed by the judge. Six months later, one of the parties marries someone else. When the parties later discover the divorce was never entered, they can obtain a judgment nunc pro tunc making the judgment final as of the date they filed it, so that the remarriage is not bigamous.
