New York Civil Practice Law & Rules R2103-A - Confidentiality of addresses in civil proceedings.

Rule  2103-a.  Confidentiality  of addresses in civil proceedings. (a)
  Notwithstanding any other provision of law,  in  any  civil  proceeding,
  whether  or  not an order of protection or temporary order of protection
  is sought or has been sought in the past, the court may,  upon  its  own
  motion  or upon the motion of any party, authorize any party to keep his
  or  her  residential  and  business  addresses  and  telephone   numbers
  confidential  from  any party in any pleadings or other papers submitted
  to the court, where the court makes  specific  findings  on  the  record
  supporting  a  conclusion that disclosure of such addresses or telephone
  numbers would pose an unreasonable risk to the health  or  safety  of  a
  party.  Pending  such a finding, any such addresses or telephone numbers
  of the party seeking confidentiality shall be safeguarded and sealed  in
  order to prevent its inadvertent or unauthorized use or disclosure.
(b) Notwithstanding any other provision of law, if a party has resided
  or  resides in a residential program for victims of domestic violence as
  defined in section four hundred fifty-nine-a of the social services law,
  the present address of such party and the  address  of  the  residential
  program  for  victims  of domestic violence shall not be revealed by the
  court or any court personnel who may have access to such information.
(c) Upon such authorization, the court shall designate  the  clerk  of
  the  court  or  such other disinterested person as it deems appropriate,
  with consent of such disinterested person, as the agent for  service  of
  process  for  the  party  whose  residential  and  business addresses or
  telephone numbers are  to  remain  confidential  and  shall  notify  the
  parties of such designation and the address of the agent in writing. The
  clerk or disinterested person designated by the court shall, when served
  with  process  on  behalf  of  the  party whose information is to remain
  confidential, promptly notify such party whose information is to  remain
  confidential  and  forward  such  process  to  him  or  her  in a manner
  calculated to be timely received.
(d) In any case in which such confidentiality authorization  is  made,
  the  party  whose information is to remain confidential shall inform the
  clerk of the court or disinterested person designated by  the  court  of
  any  change  in address for purposes of receipt of service of process or
  any papers.
