How do I de-identify contracts and legal documents for AI training?
By SourceX Editorial · Updated
Short answer
To de-identify contracts and legal documents, remove or replace party names, signatures and addresses, deal-specific prices and confidential terms protected by NDAs, check free text and attachments for hidden details, review samples by hand and exclude anything doubtful. Your company then approves the prepared copy before it leaves.
What contracts and legal documents usually contain#
Typically agreements, amendments, redlines and clause libraries. The work itself is what buyers value; the identities are not.
What to remove or replace#
At minimum: party names, signatures and addresses, deal-specific prices and confidential terms protected by NDAs. Names are often swapped for consistent placeholders so conversations still make sense.
How to check it worked#
Automated tools catch most details, but not all. Reviewers spot-check samples, look for rare facts that could point to a person, and drop records they are unsure about. Buyers are also contractually barred from trying to identify anyone.
How SourceX handles it#
SourceX starts with a short fit check that shares no data. If it fits, rights are reviewed, a copy is prepared with personal and confidential details removed, and your company approves exactly what leaves before anything is delivered under a signed license.
Frequently asked questions
Can I do the de-identification myself?
You can, but SourceX or an approved preparation partner normally does it and you review the result.
Is this legal advice?
No. It is general information; your counsel should review any specific deal.
