I just looked up the Florida Rules of Criminal Procedure, I do not see the need for the A's attorney to have filed this. They are not defendants in this case! The new attorneys did not file a notice in the civil case.
Look at the bottom right of page 20 in this file:

Notice of Appearance. An attorney who is
retained or appointed in place of the Public Defender
or Criminal Conflict and Civil Regional Counsel to
represent a defendant in a capital case shall immediately
file a notice of appearance certifying that he or she meets the qualifications of this rule. If the office
of the Public Defender or Criminal Conflict and Civil
Regional Counsel is appointed to represent the defendant,
the Public Defender or Criminal Conflict and
Civil Regional Counsel shall certify that the individuals
or assistants assigned as lead and co-counsel meet
the requirements of this rule. A notice of appearance
filed under this rule shall be served on the defendant.
