CPLR 3116 (a) provides that a deposition shall be submitted to the witness who can make changes. The witness must then sign the deposition under oath. If the witness fails to sign and return the deposition within 60 days, it may be used as fully as though signed. A failure to comply with CPLR 3116 (a) results in a party being unable to use the transcript pursuant to CPLR 3117 (see Santos v Intown Assoc., 17 AD3d 564 [2005]; Lalli v Abe, 234 AD2d 346 [1996]). It is the burden of the party proffering the deposition transcript to establish compliance with CPLR 3116 (a) (Pina v Flik Intl. Corp., 25 AD3d 772, 773 [2006]).
