What happens when you argue an appeal where there is a different attorney listed on the brief?  In some appellate courts, you just alert one of the clerks of the substitution or change.  However, I experienced something at the Appellate Division, First Department this past week.

If the attorney listed on the appellate brief will be different than the one who is going to appear at oral argument, send six labels with the new attorney's name clearly printed on it to the Clerks' office at least a week in advance.  This will save any confusion when you arrive at oral argument; the Court will likely appreciate the advance notice.
