The mandatory disclosure rule applies to all original and supplemental cases, except simplified dissolution of marriage cases and cases where the respondent is served by constructive service and does not answer.

Mandatory disclosure requires each party in a family matter to provide the other party with certain financial information and documents. These documents must be served on the other party within 45 days of service of the initial petition or supplemental petition for modification on the respondent. (from “INSTRUCTIONS FOR FLORIDA FAMILY LAW RULES OF PROCEDURE FORM 12.932“)
