Florida Juvenile Procedure Rule 8.720
(a) Summons.
(1) Personal appearance of a person in a hearing before
the court shall obviate the necessity of serving process upon that
person.
(2) Upon the filing of the petition, and upon request of
the petitioner, the clerk or deputy clerk shall issue a summons.
(3) The summons shall require the person on whom it
is served to appear for a hearing at a time and place specified.
Except in cases of medical emergency, the time of hearing shall not
be less than 24 hours after service of the summons. The summons
shall be directed to and shall be served upon the parents. It shall
not be necessary to the validity of the proceedings that the parents
be present if their identity or presence is unknown after a diligent
search and inquiry have been made; if they have become residents
of a state other than this state; or if they evade service or ignore
summons, but in this event the person who made the search and
inquiry shall file a certificate of those facts.
(b) Subpoenas. Upon the application of a party, the clerk or
deputy clerk shall issue, and the court on its own motion may
issue, subpoenas requiring attendance and testimony of witnesses
and production of records, documents, or other tangible objects at
any hearing.
