The Honorable Maureen O'Connell, Nassau County Clerk has informed us:

"... the Clerk's online database via US Land Records now gives access to uncertified images of all land documents in our database, free of charge.  This should alleviate stress and overcrowding in our search area

... Not only can a computer in an office or home now search for everything in the County Clerk land database, but the cost for doing so would be identical as doing the search in the Clerk’s office....

Also, ...  please include a reminder about the Assessment TMV letter not necessarily having an SBL that is consistent with the official County Clerk SBL.  This inconsistency is leading to submitters changing the SBL on instruments to match the Assessment letter (not the County Clerks) and creates rejections before the submission even reaches our internal system."
