Contract Understanding Atticus Dataset (CUAD)
(Commercial Contracts) Labeling Handbook

as of September 9, 2021 


Contract Understanding Atticus Dataset (CUAD)(Commercial Contracts) v1 contains 13,000+ labels in 510 commercial legal contracts with rich expert annotations. The dataset has been manually labeled under the supervision of experienced lawyers to identify 41 types of legal clauses in commercial contracts that are considered important in contract review in connection with a corporate transaction, including mergers & acquisitions, corporate finance, investments, initial public offering, etc. 

This Handbook contains selected guidelines developed by The Atticus Project to guide our volunteer annotators in curating CUAD (Commercial Contracts). This Handbook contains our interpretation of selected Atticus Labels and contract clauses solely for the purpose of curating CUAD and does not constitute legal advice. 

Access to CUAD, Atticus Labels, and this Handbook on our website is free. We encourage you to share your suggestions and ideas to this Handbook by emailing

This Handbook and our other work products are created by volunteers of The Atticus Project. Support our continuing efforts to provide you with high-quality free content by purchasing a downloadable version of the full Handbook.
