Filtering Multiple records IF they have been inputed in the last 12 months

OK, another question! I am trying to pull records 12-18 months old for appointments. The catch is there can't be any other records for an appointment within the last 12 months. How can I filter out these records? I should say each appointment has it's own record, but shares a Key.

Code:

SELECT ...
  FROM daTable AS t
 WHERE somedate ... -- 18 to 12 months ago
   AND NOT EXISTS
       ( SELECT 1
           FROM daTable
          WHERE sharedkey = t.sharedkey
            AND somedate ... -- 12 to 0 months ago  )
