Pitfalls to watch at work

Harvey

Harvey's legal sources are strongest for the US and the UK, and its knowledge of other jurisdictions is limited: check provisions in the official sources
Check case and statute references against the primary source before they go into a client document
The contract with the vendor must state that client documents are never used to train the model

Lexis+ AI

Jurisdictions outside its coverage have no legislation or case law in the database: search them separately
Check case citations against the full text of the decision before using them in a position
Access is tied to the subscription's jurisdiction: the law of another country may be unavailable
