how much amount to be paid to my consult for MACT matter

My Dad had accident in road accident seven years back (2011) and we filed MACT in rohini court (small causes)on the same year with the help of advocate. And advocate fee was discussed as 10% initially. Now we got the judgement and awarded amount is 1308000 with interest. As per Supream Court judgment court awarded 200000 for initial amount from total amount(1308000). And rest of money fixed in bank for 20 yrs. 5000+5000(interst) paid to me every month from awarded amount. So my doubt here is how i should pay the advocate. The 10% is on the awarded amount or I have to add the interest amount also.
