Hidden Challenges of AI Contract Review in Real-World Implementation  

Inhouse legal teams are increasingly exploring AI tools to accelerate contract review and improve efficiency.  However, successful implementation requires more than simply introducing new technology.  In practice, inconsistent or lack of contracting playbooks, unclear risk positions and poor prompting practices may undermine the value of AI tools.

This session shares practical lessons from rolling out AI contract review within a global in-house legal function.  Rather than focusing on the technology, this presentation explores what didn’t work as expected – including hidden inconsistencies, misalignment on fallback positions and the unexpected discipline required for effective prompting.  

  • Preparing contracting playbooks 
  • Why unclear fallback positions undermine AI contract review
  • How prompting discipline shapes and improves AI outputs 
  • Unexpected implementation challenges and overcoming them
  • Lessons learnt from deploying AI contract review across a global legal team

3 Key Learnings

  1. Why AI contract review fails without clear playbooks and fallback positions 
  2. How structured prompting improves consistency and legal risk and contractual analysis 
  3. Implementation mistakes (and ways to overcome them) when deploying AI contract review tools
