(a) The judges of the superior, state, and city courts, when counsel for either party requests it before argument begins, shall write out their charges and read them to the jury; and it shall be error to give any other or additional charge than that so written and read; provided, however, that this Code section shall not apply when there is an official court reporter in attendance thereon who records the full charge of the trial judge in the case upon the direction of the court.
(b) In any civil action, upon motion by a party, upon request by the jury, or sua sponte, a judge of a superior, state, or city court is
authorized, but shall not be required, to reduce all of the charge to the jury to writing and send all of the charge so reduced to writing out with
the jury during its deliberation.
(c) Any charge reduced to writing under subsection (a) or (b) of this Code section shall be filed with the clerk of the court in which it was given and shall be accessible to all persons interested in it. The clerk shall give certified copies of the charge to any person applying therefor,
upon payment of the usual fee.
