AI for Legal
In law firms AI lifts three tasks: document review, finding case law across national and European databases, and drafting first versions of letters and contracts. Firms that have adopted these tools raise throughput by 40% without growing the team. The caveat here is heavier than in other sectors: a language model will produce a case citation that reads plausibly and does not exist. Every output goes past a lawyer before it reaches a file - otherwise this is not a saving, it is deferred risk.
Three uses of AI in Legal
Contract review and comparison
The system reads contracts and flags risky clauses, missing provisions, divergence from the firm's template and departures from market standard. The model is trained on the relevant civil and commercial law, handles the terminology, and gives its reasoning with every change it proposes.
Case law search and legal research
A RAG pipeline searches national court decisions, commentary and legislation and assembles a research note with judgments, holdings and argument. Results are ordered by relevance and currency, which removes several hours of database work.
Drafting pleadings and documents
From the facts and the firm's templates, AI drafts pleadings, letters before action, contracts and opinions. It reaches for current legislation and case law, formats to the firm's standard and attaches the legal basis with sources.

What makes it hard
Hallucination in a legal context - citing provisions or judgments that do not exist demands rigorous validation
Legal professional privilege - client data cannot go to an external API without the right safeguards
Legislation changes often, so the knowledge base needs continuous updating against the official gazette
Lawyers resist changing how they work, so adoption has to be staged and the value shown
Frequently asked questions
Is our clients' data safe?
Yes. We deploy on-premises or on a dedicated EU server, where data never leaves the firm's infrastructure. Where an external API is needed, data is anonymised before it goes. The whole system is built to meet professional secrecy obligations and GDPR.
What does legal AI cost?
Contract review is €7,000-14,000, a RAG case-law search €6,000-11,500, a document generator €4,500-9,500. The full package with integration runs €14,000-28,000. Maintenance: €700-1,900 a month.
Can AI make a legal error the firm answers for?
AI is a support tool, not a substitute for a lawyer - every generated document is checked by one, and the responsibility is theirs. The system runs human-in-the-loop and marks the passages that need verification.
