body: I'm being asked to sign a letter of engagement with an attorney.
  
  
  One of the numbered paragraphs is blank and just says "Reserved". What is the reason for it, can the attorney just insert whatever terms they want later? Clearly not, but it must have some purpose.
  
  
  This letter is being presented on an online signing service if that matters.
  
  
  
title: What is a "Reserved" clause in a contract? (letter of engagement)
