My understanding, based on what I've just read, is that it depends on whether the document was created in order to obtain legal advice.
If you start the document with "Dear Lawyer, here is my story so far including all the incriminating bits" then that is privileged. However if you write "Dear Joe, hide the money from the robbery in rented garage" and subsequently send a copy to your lawyer then it is not privileged. Both of these are true regardless of when you wrote the document or hired the lawyer.
This is always a tricky problem, especially with a computer which may contain both privileged information and unprivileged evidence of a crime. See https://www.justice.gov/sites/default/files/criminal-ccips/l... starting at page 109 for more on how the police are supposed to deal with this.
