N.J. Stat. § 34:15-26
When any proceedings have been taken under the provisions of article two of this chapter, the bureau or the Superior Court shall, as a part of the determination and order, either for payment or for commutation of payment, settle and determine the amount of compensation to be paid by the injured employee or his dependents, on behalf of whom such proceedings are instituted, to his legal advisers, and it shall be unlawful for any lawyer, or other person acting in that behalf, to ask for, contract for or receive any larger sum than the amount so fixed. In the order determining weekly payments where no commutation is made, the bureau or the court shall also determine the amount to be paid per week from the compensation payment on account of the legal fee thus awarded, and it shall be unlawful for the legal adviser, or other person acting in that behalf, to ask for, contract for or receive a larger sum per week than the allowance thus determined.
