N.J. Stat. § 2A:152-17
Any person convicted of any crime may make application under oath to any judge of the Law Division of the Superior Court of the county where the venue was laid showing that a copy of the transcript of the record, testimony and proceedings at the trial is necessary for the filing of any application with the trial court, and that he is unable, by reason of poverty, to defray the expense of procuring the same, and any such judge may, being satisfied of the facts stated and of the sufficiency thereof, certify the expense thereof to the county treasurer, who shall thereupon pay such expense, the amount thereof having been approved by the judge to whom such application was made. Where such person appeals to the Appellate Division of the Superior Court and copies of the transcript of the proceedings in the trial court are needed therefor he may make a similar application to such court which, being satisfied of the facts stated and the sufficiency thereof, may certify the expense and amount thereof to the county treasurer who shall thereupon pay such expense.
