N.Y. Civil Practice Law & Rules § 1101
(e) When motion not required. Where a party is represented in a civil action by a legal aid society or a legal services or other nonprofit organization, which has as its primary purpose the furnishing of legal services to indigent persons, or by private counsel working on behalf of or under the auspices of such society or organization, all fees and costs relating to the filing and service shall be waived without the necessity of a motion and the case shall be given an index number, or, in a court other than the supreme or county court, an appropriate filing number, provided that a determination has been made by such society, organization or attorney that such party is unable to pay the costs, fees and expenses necessary to prosecute or defend the action, and that an attorney's certification that such determination has been made is filed with the clerk of the court along with the summons and complaint or summons with notice or third-party summons and complaint or otherwise provided to the clerk of the court. Where an attorney certifies, pursuant to section eleven hundred eighteen of the family court act, and in accordance with procedures of the appropriate appellate division, that a party or child who is the subject of an appeal has been represented in the family court by assigned counsel or by a legal aid society or a legal services or other nonprofit organization, which has as its primary purpose the furnishing of legal services to indigent persons, or by private counsel working on behalf of or under the auspices of such society or organization, and, in the case of a counsel assigned to an adult party, that the party continues to be indigent, the party or child shall be presumed eligible for poor person relief pursuant to this section. * (f) Fees for incarcerated individuals. 1. Notwithstanding any other provision of law to the contrary, a federal, state or local incarcerated individual under sentence for conviction of a crime may seek to commence his or her action or proceeding by paying a reduced filing fee as provided in paragraph two of this subdivision. Such incarcerated individual shall file the form affidavit referred to in subdivision (d) of this section along with the summons and complaint or summons with notice or third-party summons and complaint or petition or notice of petition or order to show cause. As part of such application, the incarcerated individual shall indicate the name and mailing address of the facility at which he or she is confined along with the name and mailing address of any other federal, state or local facility at which he or she was confined during the preceding six month period. The case will be given an index number if applicable, or, in courts other than the supreme or county courts, any necessary filing number and the application will be submitted to a judge of the court. Upon receipt of the application, the court shall obtain from the appropriate official of the facility at which the incarcerated individual is confined a certified copy of the incarcerated individual's trust fund account statement (or institutional equivalent) for the six month period preceding filing of the incarcerated individual's application. If the incarcerated individual has been confined for less than six months at such facility, the court shall obtain additional information as follows:
2. If the court determines that the incarcerated individual has insufficient means to pay the full filing fee, the court may permit the incarcerated individual to pay a reduced filing fee, the minimum of which shall not be less than fifteen dollars and the maximum of which shall not be more than fifty dollars. The court shall require an initial payment of such portion of the reduced filing fee as the incarcerated individual can reasonably afford or shall authorize no initial payment of the fee if exceptional circumstances render the incarcerated individual unable to pay any fee; provided however, that the difference between the amount of the reduced filing fee and the amount paid by the incarcerated individual in the initial partial payment shall be assessed against the incarcerated individual as an outstanding obligation to be collected either by the superintendent or the municipal official of the facility at which the incarcerated individual is confined, as the case may be, in the same manner that mandatory surcharges are collected as provided for in subdivision five of section 60.35 of the penal law. The court shall notify the superintendent or the municipal official of the facility where the incarcerated individual is housed of the amount of the reduced filing fee that was not directed to be paid by the incarcerated individual. Thereafter, the superintendent or the municipal official shall forward to the court any fee obligations that have been collected, provided however, that:
