Nexa Legal
A Belgian AI platform for litigation lawyers that pulls case-file analysis, legal research, argumentation and drafting into one guided workflow, running on a firm's own case files and on Belgian legislation and case law.
What is Nexa Legal?
Nexa Legal is a software-as-a-service platform that applies AI to litigation work, published by Nexa Legal BV in Mortsel, near Antwerp. It describes itself as the AI work layer for litigation, and insists on that framing: rather than another separate tool, it is meant to sit on top of the case files, systems and data a firm already has, alongside intake, research, argumentation and drafting.
The platform is offered in two ways of working. The Case Flow Wizard takes a matter end to end, walking a lawyer step by step from identifying the parties through to writing the final brief; it is presented as the option for complex cases where full guidance is wanted. The Agent Market Place does the opposite, letting a lawyer pick a specialised agent for one defined task. Named agents include a Law Checker and a Translator, next to a secure AI chat running on what the vendor calls top models.
Four stages are covered. Intake and analysis loads an entire file and returns structure and insight rather than working document by document. Research combines public sources, professional sources and the firm's internal database into one contextual answer. Argumentation produces a first draft of the reasoning and then challenges it, surfacing weaknesses and comparing conclusions. Drafting generates documents from the firm's own templates and case material.
Two claims carry most of the positioning. The first is scale: the platform says it handles files of 1,000 or more documents where generic assistants are very limited. The second is jurisdiction: it accounts for Belgian context, case law and practice, which is also why it is sold mainly in Belgium and the Netherlands. Connection to practice management systems happens at two depths, case level or database level, with LawCloud, Toga, iManage and SharePoint named.
Nexa Legal sells through demonstrations rather than self-service signup, and bundles on-site implementation, onboarding and continuing adoption support with the licence. The vendor reports more than 100 law firms as customers and publishes named testimonials, a 4.8 out of 5 rating and efficiency figures, all of them self-declared.

- Draft conclusions and documents in the firm's own templates and writing style
- Search internal databases and archives alongside public legal sources
- Check applicable law through the dedicated Law Checker agent
- Translate legal material through the dedicated Translator agent
When to use Nexa Legal / When not to
A quick filter to help you decide if Nexa Legal is the right fit.
When to use Nexa Legal
- Litigation lawyers in Belgium and the Netherlands who spend more time on execution than on strategy
- Solo practitioners and small firms wanting senior-level throughput without hiring
- Large firms handling voluminous files, where the platform claims to work across 1,000+ documents
- Firms already running a practice management system such as LawCloud, Toga, iManage or SharePoint
- Practices that want on-site implementation and ongoing coaching rather than a licence and a login
When not to use Nexa Legal
- Lawyers working outside Belgian law, since the tool's stated edge is Belgian context, case law and practice
- Anyone looking to try before buying: there is no free plan and no free trial, only a 30-day money-back guarantee
- Occasional users, for whom the EUR 195 per user per month entry ticket is hard to justify
- Teams needing an API or a mobile app to embed legal AI in their own systems, as neither exists
- Buyers who require an independent security certification, since no ISO 27001 or SOC 2 audit is claimed
How to use Nexa Legal
A typical end-to-end flow, from setup to results.
- Request a demonstration through the website form, as there is no self-service signup
- Discuss the firm's setup and current practice management system with the vendor
- Take out a Standard licence per user, or ask for a tailored proposal for a broader team rollout

- For a complex matter, start the Case Flow Wizard and follow the guided flow to the final brief
- For a defined task, pick the relevant agent from the Agent Market Place instead
- Rely on ongoing optimisation, webinars, best practices and the direct support line as usage grows

Data, GDPR & hosting
A consolidated view of how Nexa Legal handles your data.
GDPR overview
GDPR compliance is claimed explicitly, in the wording "GDPR & OVB-compliant (EU-servers)" and "GDPR-compliant & legally responsible use (EU hosting)". The commitments are concrete: an Article 28 processing agreement, an Article 30 record of processing available to the supervisory authority, assistance with data subject requests and DPIAs under Articles 12-23, 32, 35 and 36, and breach notification under Articles 33 and 34. Processing stays inside the EEA; any transfer outside relies on the EU Standard Contractual Clauses, an adequacy decision or another Chapter V mechanism, with a transfer impact assessment where relevant. Belgian law governs, with the Dutch-speaking courts of Antwerp. Two gaps: no data protection officer is named and no dedicated privacy mailbox exists, so everything goes through a single general address.
Who owns the data?
The law firm remains the data controller and keeps ownership of its case files; Nexa Legal BV acts only as a processor. Its Data Processing Agreement, Annex C to the Nexa AI Case Assistant licence agreement in its 30 June 2026 version, binds it to process personal data solely on the controller's written instructions. Confidentiality is imposed on everyone with access, and every sub-processor must be held to at least the same obligations. When the services end, the firm chooses whether the data is deleted or returned, subject to statutory retention. An export is supplied on request before deletion, and the firm may audit compliance once every twelve months.
Reuse rights
Nexa Legal states it uses personal data to deliver and operate its AI services, support customers, handle contracts and invoicing, secure and improve the service, send marketing with consent, and meet legal obligations. It commits in writing that customer-supplied data is never used to train AI models, to profile anyone or for marketing. The firm that uploads the material keeps control of it and may reuse it freely; the vendor may not repurpose it, and any processing outside the documented instructions would breach the agreement. Special-category data is not intended to be processed, but the terms accept it may appear incidentally when a firm uploads documents containing it.
Data retention & training
Hosting summary
All processing is stated to take place within the European Economic Area. The sub-processor list, published as Annex 3 of the Data Processing Agreement and last updated on 29 June 2026, names each party and its country. Scaleway SAS in France provides the hosting and compute platform, with Amazon Web Services also listed for hosting and compute in an EEA region without a country given. AI model inference runs on Google Cloud EMEA through Vertex AI in an EU region and on the Microsoft Azure OpenAI Service in an EU region. Legal Data Hunter in France supplies legal source material through an API. Mixpanel holds product analytics under EU data residency in the Netherlands, explicitly without case content, documents, prompts or AI output. Tech Tribes Sourcing in Belgium handles software development and maintenance. Any transfer outside the EEA would rely on the EU Standard Contractual Clauses with additional safeguards and, where relevant, a transfer impact assessment. Changes to the list are announced in advance, with 30 days' notice under the agreement.
Things to keep in mind
Risks and trade-offs to weigh before adopting Nexa Legal.
- Legal responsibility never transfers to the tool: drafted arguments and generated documents remain the lawyer's work and must be verified line by line before filing
- Fluent, well-structured legal output invites over-trust; a plausible citation or a confidently framed argument still needs checking against the source
- Routine reliance on a guided flow can erode the drafting and reasoning skills junior lawyers build precisely by doing that work themselves
- Uploading client files to any third-party platform touches legal privilege; the DPA and EEA hosting mitigate this but do not remove the duty to assess it
- The vendor's efficiency figures, its 4.8 rating and the claim that 95% of testers become customers are self-declared with no published methodology
- The website carries residues of a rebrand: the canonical tag still points to the former nexa-ai.be domain, the page title keeps the old Nexa AI name, and the built-in NDA generator prints the wrong postcode for the registered office
- No independent security certification backs the security measures described, and the site returns its homepage for any unknown path, so a working link is no evidence that a page exists
Setup & Integrations
Technical difficulty
Low for the end user, because the vendor does the work. There is no self-service signup: access starts with a demonstration, then a licence. Nexa is set up in the firm's environment and configured to its way of working, with the practice management system connected either at case level or, for deeper access, at database level. Custom connectors are available on request. The platform runs in the browser, so nothing is installed on the workstation, and the agents are presented as ready to use without training. Personal onboarding, team training, a dedicated contact and ongoing adoption follow-up are included.

Should you pick Nexa Legal?
Nexa Legal is a narrow product, and that is its strength. Rather than promising general legal intelligence, it commits to one jurisdiction and one kind of work: litigation under Belgian law, carried out inside the case files and practice management systems a firm already uses. The two entry points are coherent, a guided flow for complex matters and single-task agents for everything else, and the emphasis on whole-file analysis rather than document-by-document work is a real distinction from generic assistants.
For a company incorporated only in August 2025, the data protection posture is notably thorough: a complete processing agreement, a dated and itemised sub-processor list, processing kept within the EEA, and an unconditional written commitment not to train models on customer data. That last point matters for a profession bound by legal privilege. The gaps are equally visible: no independent security certification, no named data protection officer, and a single general mailbox still sitting on the vendor's former domain.
Commercially the offer is blunt. A published price is welcome, but EUR 195 per user per month with no free plan and no trial means committing before evaluating, softened only by a 30-day money-back guarantee. Team pricing is not disclosed. The efficiency claims - five times faster research, double the capacity, forty percent more billable value - along with the 4.8 rating and the assertion that 95% of testers become customers, are all vendor-declared with no published methodology, and should be read as marketing rather than measurement.
The proposition is credible for a Belgian litigation practice already running a supported case management system and willing to buy on the strength of a demonstration and an implementation commitment. Outside that profile, the case is much weaker.
