License contracts, briefs, templates and other legal documents for legal AI training. Privilege, client confidentiality and redaction explained.

## Summary

- Legal AI models learn drafting and analysis from real contracts, briefs, memos and templates.
- Client documents are protected by confidentiality and often privilege, and a sale can waive privilege.
- Firm-owned precedents and templates are the usual starting point for a law firm license.
- Public court filings can be useful but carry their own redaction issues.

## Start with what the firm owns

Precedent banks, templates, internal know-how notes and training materials usually belong to the firm. These are the easiest legal assets to license, and they are exactly what legal AI vendors want: examples of good drafting with explanations.

## Client material

Client documents are confidential under professional rules and often privileged. Lawyers advising on AI data sales note that selling legal communications may waive privilege ([Frankfurt Kurnit Klein & Selz](https://technologylaw.fkks.com/post/102o455/selling-company-data-for-ai-training-what-to-know-before-you-say-yes)). Client material should only be considered with informed client consent and thorough redaction, and many firms exclude it entirely.

## Questions

### Can a law firm sell its precedents?

Usually yes, for firm-owned templates and precedents, after removing client details. Check partnership agreements and bar guidance in your jurisdiction.
