Drafting a clear and concise contract is the drafter’s ultimate goal. Uncertainty, or lengthy, complicated and confusing terminology can result in misunderstandings and contracts that don’t clearly express the intent of the parties.

In this session, Ken will address the efficient use of defined terms and explore the different forms of ambiguity along with how to avoid them when drafting. Specific topics include:

  • Understanding the two kinds of definitions
  • Role of the definition section
  • Proper use of defined terms to ensure consistency and clarity
  • How vagueness can be an essential drafting tool
  • Ambiguity of the part vs. the whole
  • Strategic use of modifiers, including ‘that’ and ‘which’
