§ 5-712. Confirmation notices.  1. The board of elections shall send a confirmation  notice  by  forwardable  first  class  or  return  postage guaranteed mail to every registered voter or applicant for registration, at the address at which the voter is registered or the  address  on  the application  for  registration,  when  any  mail  sent  to such voter or applicant is returned as undeliverable by the postal service without any indication of a forwarding address and to any voter for whom notice that the voter has moved without leaving a forwarding  address,  is  received from  the  United  States  Postal Service through the National Change of Address System.   2. (a) The board of elections shall also send a confirmation notice to every registered voter for whom  it  receives  a  notice  of  change  of address  to an address not in such city or county which is not signed by the voter.  Such change of address notices shall  include,  but  not  be limited   to,   notices  of  change  of  address  received  pursuant  to subdivision eleven of section 5-211 and subdivision six of section 5-212 of this article, notice of change of  address  from  the  United  States Postal Service through the National Change of Address System or from any other  agency  of  the  federal government or any agency of any state or local government and notice of a forwarding address on mail  sent  to  a voter by the board of elections and returned by the postal service. Such confirmation notices shall be sent to such new address.  (b)  If a notice sent pursuant to paragraph (a) of this subdivision to the voter at the new address is returned as undeliverable, the board  of elections  shall  send  another  such notice to the address at which the voter was originally registered.   3. Such notices shall be in a form prescribed by the  state  board  of elections  and  shall  include  a  postage-paid return card on which the voter may confirm the fact that he still resides at the address to which the notice was sent, or notify the board of any change of address.  Such notices  shall  request  all voters who receive the notice to reply with their current addresses. Such  notices  shall  request  all  voters  who receive the notice to reply with their current addresses and shall state that  voters  who  have not moved or who have moved within the county or city and who do not respond may be required to vote by affidavit  ballot and  that  if  they  do not vote in any election up to and including the second federal election after such notice, their  registrations  may  be cancelled.   Such notices sent to addresses in New York state shall also include a mail registration form and information on how voters who  have moved to a different city or county may reregister.   4.  No  such  confirmation notices shall be sent between June first in any year and the date of the general election in such  year  or  in  the ninety  days  before  a spring primary election except that such notices shall be sent  forthwith  to  persons  for  whom  an  acknowledgment  of acceptance  of registration sent pursuant to subdivision nine of section 5-210 of  this  article  is  returned  to  the  board  of  elections  as undeliverable  and  to  every  registered  voter  for  whom the board of elections receives a notice of change of address described in  paragraph a  of  subdivision two of this section to an address not in such city or county.   5. All voters or applicants to whom a  confirmation  notice  is  sent, pursuant to the provisions of this section, shall forthwith be placed in inactive status.
