What happens if my Husband dies during a divorce case?

It depends on whether a final Judgment has been entered or not. The relevant rules of court authorize the trial court to permit the Estate to be substituted as a party in the event of death provided the claim is not extinguished by death. Florida law provides that the death of a spouse prior to the entry of a Final Judgment terminates the suit and requires dismissal of same. See King v. King 36 FLW D1651a
