A client who incurred a $1.5 million bill for legal services with New Jersey law firm Sills Cummis & Gross has accused the firm in a suit of padding its bill.

Sills Cummis allegedly overstaffed the matter and charged the client twice or multiple times for the same work, according to the suit filed Monday in Passaic County Superior Court by Richard Hekemian of Oradell. The suit also claims that accounting firm CohnReznick, whose services were recommended by Sills Cummis, likewise engaged in excess billing of Hekemian.
