A party may only serve 30 interrogatories ( including subparts ) on any party. If a party wants to serve more than 30, it must be with leave of court with good cause shown.
If the Florida Supreme Court has approved a form of interrogatories for a type of action, the party is required to use the form approved in its initial set of interrogatories. However, the party may reduce or add to the approved form, but the total may not exceed 30, including subparts.
That is, if certain interrogatories of the court-approved interrogatories are not relevant to your case, delete them or better yet, change them to a question, which is relevant to your case. You do not need leave of court to make that change as long as it does not exceed the 30 limit.
