(a) At the time of filing with the clerk of the proof of service of the summons and complaint in an  action  arising out  of a consumer credit transaction, the plaintiff shall submit to the clerk a stamped, unsealed envelope addressed to the  defendant  together with  a  written  notice  in  clear type of no less than twelve-point in size,  in  both  English  and  Spanish,  and  containing  the  following language:                       ADDITIONAL NOTICE OF LAWSUIT  (NAME OF COURT) (COUNTY) (STREET ADDRESS, ROOM NUMBER) (CITY, STATE, ZIP CODE)  (NAME OF DEFENDANT) (ADDRESS OF DEFENDANT)  Plaintiff: Defendant: Name of original creditor, unless same: Index number:  Attention:  a  lawsuit  has been filed against you claiming that you owe money for an unpaid consumer debt. You may wish to contact an attorney.   You should respond to the lawsuit as soon as  possible  by  filing  an "answer" which may be done at the court clerk's office listed above.   If  you  do  not  respond  to the lawsuit, the court may enter a money judgment against you. Once entered, a judgment is good and can  be  used against  you  for  twenty  years,  and your personal property and money, including a portion of your paycheck and/or bank account, may  be  taken from  you.  Also, a judgment may affect your credit score and can affect your ability to rent a home, find a job, or take out a loan. You CANNOT be arrested or sent to jail for owing a debt. Additional information can be found at the New York state  court  system website.

(b)  The  face  of the envelope shall be addressed to the defendant at the  address  at  which  process  was  served,  and  shall  contain  the defendant's name, address (including apartment number) and zip code. The face  of the envelope also shall state the appropriate clerk's office as its return address.  (c) The clerk promptly  shall  mail  to  the  defendant  the  envelope containing  the  additional  notice set forth in subdivision (a) of this section. No default judgment based on the defendant's failure to  answer shall be entered unless there has been compliance with this section, and at least twenty days have elapsed from the date of mailing by the clerk. No  default judgment based on the defendant's failure to answer shall be  entered  if  the  additional  notice  is  returned  to  the   court   as undeliverable.  Receipt  of  the additional notice by the defendant does not confer jurisdiction on the court in the absence of proper service of process.  (d)  The  chief administrative judge shall issue a Spanish translation of the notice in subdivision (a) of this section and shall maintain  and publish  the  URL address for the web page containing consumer resources for unrepresented litigants.   * NB Effective May 7, 2022
