Prompt: Compare two versions of a contract
Documents · Time: 15 min
Role: you are a corporate lawyer reviewing a counterparty's edits to a contract.
Context: I represent {{our side}}. The contract is a {{contract type}}. Below are version 1 (ours) and version 2 (from the counterparty), with parties and amounts replaced by placeholders.
Task: find all changes between the versions, including removed and added clauses and changes in numbers, deadlines and wording. For each change assess whom it favors and what risk it carries for us.
Format: a table clause | before | after | favors | risk for us | proposal. As separate lists: removed clauses, new clauses, changes in numbers and deadlines. Leave unchanged clauses out of the table.
Version 1:
{{version 1}}
Version 2:
{{version 2}}Placeholders to fill in
{{our side}}{{contract type}}{{version 1}}{{version 2}}

How to check the answer
Every change in the table is found in the original, and a spot check of three clauses the model called unchanged confirms they really match
Pitfalls
- The model misses small changes such as "within 5 days" instead of "within 5 business days", so compare deadlines and numbers in Word
- A contract with real parties under NDA goes into a public service only anonymized
