NL 10608.105 What are the Standards for Notice Cover Letters?
Cover letters should be either automated or preprinted. They should adhere to the
same standards as notices with the following exceptions:
Do not include signatures on cover letters.
Staple the cover letter on top of the notice so it is the first thing the person sees
when opening the notice.
Type, do not handwrite, the person’s name and address on a pre-printed cover letter.
