Legal Question in Family Law in Florida

Typographical errors do not normally invalidate pleadings or other legal documents. The substance and intent of the court is still true even if dates are wrong.

Are you saying you want to invalidate your divorce decree and refile - to hopefully get a better deal next time around? You could try it, but I wouldn't based on an incorrect date in the order. Just my opinion.

No need to; you are still divorced despite the typo

If, in a divorce petition, someone states the wrong marriage date, the person answering the divorce petition should deny the allegation containing the marriage date. If the allegation isn't denied (or even if it is denied and not brought up during the trial) and the divorce proceedings conclude, the divorce is over. It can't be reopened. The marriage date isn't usually irrelevant, anyway. Usually, the judge just needs to know how long the marriage lasted to see if alimony can be awarded. If you didn't bring up the error during the divorce proceedings, it's too late now, even if the date was important.
