I paid my lawyer a retainer and now the case is closed. I presume the retainer was placed in trust (that is standard procedure, correct?). Upon review of the billing statement, there are a some fees (a non-trivial fraction) that I dispute. Can the attorney take money from the retainer in trust if I dispute the fees? Also, are there standard ethical billing practices? I did not receive regular monthly billing detail, and thus was not in the loop as to the charges incurred (otherwise would have disputed them earlier).
