AI Agents for Law Firms: From Legal Research to Work That Moves Forward
How law firms can combine source-based legal research, firm knowledge and configurable AI workflows without losing control of client matters.
A legal question rarely arrives as a neat research prompt. It arrives with an email chain, an incomplete set of documents, an urgent deadline and instructions that may change after the first call.
Finding the law is one part of the job. Organising the matter, applying the firm’s methods and preparing the next step are another. An AI workflow can help connect those pieces if the firm defines the boundaries first.
An illustrative matter: the missing annex
A client emails a contract and asks for a risk summary. The attachment refers to an annex that is not included. An agent could identify the missing annex, organise the available files and prepare a request for it. It could then compare the contract with the firm’s authorised playbook and produce a draft list of points for a lawyer.
The example is illustrative, not a client case or a claim that the system makes legal decisions. The firm decides whether a routine request is sent directly or reviewed; a lawyer remains responsible for legal advice and professional obligations.
Separate law, firm knowledge and matter facts
These are different collections with different rules. The law requires the correct jurisdiction, official source and applicable version. Firm knowledge includes approved precedents, clause positions and checklists that need ownership and revision. Matter facts belong to a client and may be disputed or incomplete.
Do not let a model present an unverified client assertion as an established fact, or use a precedent from another client without appropriate permission and preparation. A useful output identifies its source and flags what is missing.
| Information | Example | Control to define |
|---|---|---|
| Legal source | Official legislation or a judgment. | Authority, date and applicable version. |
| Firm knowledge | Approved checklist or precedent. | Owner, updates and permitted users. |
| Matter material | Client correspondence and attachments. | Matter access, confidentiality and retention. |
AiLexLux for research; DigiRAG for the workflow
AiLexLux supports legal research across Luxembourg, French and EU law with access to official sources. Use it to investigate authorities and inspect the relevant material. Check the version, context and interpretation before relying on an answer.
DigiRAG can organise authorised documents and power agents that classify requests, retrieve permitted knowledge, prepare drafts and use configured tools. AiLexLux provides an MCP interface and DigiRAG supports MCP integrations out of the box. This integration has been tested and is operational in real customer environments, so an appropriately configured DigiRAG agent can use AiLexLux research in a wider legal workflow. Each firm determines its connection, access rights, processing and review settings.
How to bring legal research into an agent
One practical starting point is an agent that prepares a source-linked research note for a lawyer, without sending advice to the client. Connect the AiLexLux MCP server in DigiRAG under Settings → MCP using the connection details and access authorised for your organisation. In the agent designer, add the available AiLexLux tool to the agent node; select the firm’s permitted datasets separately if the workflow also needs internal precedents.
Give the agent the jurisdiction, relevant date and research question, and instruct it to return source references and uncertainties. In later steps, explicitly pass the research result into the drafting context: a downstream model does not automatically see a previous node’s output. Test an ordinary question, an unavailable source and a failed connection. An MCP error returned as text does not automatically stop a later email action, so add explicit failure handling before any permitted external action.
Design the boundaries around the matter
Set up access by role, team and matter as appropriate. Decide which documents each agent may retrieve, which provider processes the question, what is logged and how long material is retained. Map external tools, subprocessors and backups as well as the application itself.
For professional secrecy and data protection, assess the actual deployment, contracts and client instructions with the firm’s responsible advisers. Hosting a document in a private environment does not by itself establish where every model or integration processes its contents.
Pilot one useful step
Choose a task where a lawyer can judge the output, such as identifying missing documents or creating a chronology with source references. Use representative, authorised material and include difficult cases.
- Define the task, exclusions and expected output before selecting tools.
- Test access: a user must not retrieve another matter simply because it is searchable.
- Require uncertainty, conflicting dates and missing pages to be flagged.
- Set action permissions: a draft, an internal update and an external message need different decisions.
- Review sources, time spent correcting output and failures; assign a person to maintain the process.
Questions we often hear
Can a legal agent replace conflict checks or legal judgment?
No. An agent may help organise information, but the firm’s authorised conflict, acceptance and professional decision processes still apply.
Must every action wait for a person?
No. The firm configures which permitted actions run directly and which require review, taking account of professional responsibilities and risk.
