NY Elec L § 8-304 (2021)
2021 New York Laws ELN - Election Article 8 - Conduct of Elections Title 3 - Casting the Ballot 8-304 - Voters; Signature Identification.

§  8-304.  Voters;  signature identification. 1. A person before being   allowed to vote shall be required, except as provided in  this  chapter,   to  sign  his  or  her  name on the back of his or her registration poll   record on the first line reserved for his or her signature at  the  time   of  election  which  is  not filled with a previous signature, or in the   space provided in the computer generated registration list reserved  for   the  voter's  signature.  The  two  inspectors  in  charge shall satisfy   themselves  by  a  comparison  of  this  signature  with   the   voter's   registration  signature and by comparison of the voter's appearance with   the descriptive material on the face of  the  registration  poll  record   that  the  voter is the person registered. If they are so satisfied they   shall enter the other information required for the election on the  same   line  with  the  voter's  latest  signature,  shall  sign their names or   initials in the spaces provided therefor, and shall permit the applicant   to vote. Any inspector or inspectors not satisfied shall  challenge  the   applicant forthwith.2.  If  a  person  who  alleges  an  inability to sign his or her name   presents himself or herself to  vote,  the  board  of  inspectors  shall   permit such person to vote, unless challenged on other grounds, provided   the  voter  had  been  permitted to register without signing the voter's   name. The board shall enter the words "Unable to Sign" in the  space  on   the  voter's registration poll record reserved for the voter's signature   or on the  line  or  space  the  computer  generated  registration  list   reserved  for  the  voter's  signature  at such election. If the voter's   signature appears  upon  the  voter's  registration  record  or  in  the   computer generated registration list the board shall challenge the voter   forthwith,  except that if such a person claims that he or she is unable   to sign his or her name by reason  of  a  physical  disability  incurred   since the voter's registration, the board, if convinced of the existence   of  such  disability,  shall  permit him or her to vote, shall enter the   words "Unable to Sign" and a brief description of such disability in the   space reserved for the voter's  signature  at  such  election.  At  each   subsequent election, if such disability still exists, the voter shall be   entitled to vote without signing their name and the board of inspectors,   without  further notation, shall enter the words "Unable to Sign" in the   space reserved for the voter's signature at such election.3. The voter's facsimile signature shall be effectively concealed from   the voter by a blotter or other means until after the voter  shall  have   completed the signature.4.  In any case where a person who has heretofore voted has placed his   voting signature on the back of his  registration  poll  record  on  the   first  or  any  succeeding  line  or  lines  at  the time or times of an   election, instead of on the last line of the space thereon  required  to   be  reserved  for  such  voting signatures and on any lines next running   upward therefrom, the  inspectors  of  election  shall  obliterate  such   misplaced  signature or signatures, initial the obliteration and require   such voter to  sign  his  name  again  in  the  correct  place  on  such   registration poll record.5.  Any  person  who  has  heretofore  registered and who at such time   placed his or her registration signature on the back of the registration   poll record otherwise than in the space required to be provided therefor   at the bottom of such poll record, shall, before being permitted to vote   at any election thereafter, subscribe a new registration  signature  for   himself  on the last line at the bottom of such poll record, and, at the   same time,  if  the  inspectors  of  election  are  satisfied  that  the   signatures  were  made  by  the  same  person,  obliterate  his original   registration signature placed elsewhere  than  on  the  bottom  of  such   record.  Such obliterations may be made by crossing out the signature so    as to completely efface the same or by affixing  thereover  a  piece  of   gummed  tape  of a size sufficient only to cover such signature and of a   type adequate to fully conceal the same.
