Hi OP! Advocate here.
Whenever cost is imposed by an court, it is pertinent for the court to also mention to whom such cost must be paid. Please go to the court and apply for a certified copy of the daily order and peruse the same. It will be clearly mentioned.
In your case, however, since your advocate has retained the said amount, in all possibility the cost was given to you and your advocate has cleverly kept it to himself/herself (which although I do not condone, is a fairly common practice in the lower courts).
