These are the 7 key points this article covers on what legal teams and DPOs need to know about the AI Act:
- Why the AI Act is not only an engineering topic
- What role the legal team and DPO play in AI governance
- How risk classification works and what you should review first
- What the high-risk category implies for documentation load
- What changes with foundation models and general-purpose purpose
- How to connect the AI Act and the GDPR without duplicating efforts
- Mistakes that can slow you down when you start (and how to address them)
The AI Act is no longer “just a conversation”.
It is a legal framework that affects how AI systems are designed, integrated, and operated.
And while engineering is key, AI Act governance requires interpretation, documentary traceability, and coordination with data protection and legal responsibilities.
Why the AI Act also affects legal teams and DPOs
When an organisation incorporates AI into products, processes, or decision-making, legal and fundamental-rights questions emerge.
Those questions do not disappear once you deliver “the technical part”.
The legal team and the DPO are usually the ones who already handle: risk, responsibility, documentation, and coordination across areas.
The AI Act reinforces that fit by turning governance into a verifiable process: classify, document, supervise, and demonstrate.
What legal brings vs what the DPO brings (without stepping on each other)
The legal team typically leads normative interpretation, contracts, responsibility, and governance toward executive management.
The DPO typically leads the link with data protection, people’s rights, and coherence with the existing privacy program.
The AI Act does not “replace” the DPO, but it does require the DPO to understand where AI touches personal data and where AI governance needs bridges with DPIAs, records of processing activities, and privacy policies.
If both teams work in silos, the typical outcome is duplicated or contradictory documentation.
Risk classification: what legal teams and DPOs should review first
The first practical step is to understand which category your AI use case falls into.
The AI Act uses a layered model: prohibited systems, high-risk, transparency obligations, and in some cases, minimal risk.
For the legal team and the DPO, classification is not a theoretical exercise.
It determines which documentation is needed, which control mechanisms must exist, and how internal responsibilities are managed.
In practice, before you “write procedures”, review: what real use cases exist, what impact they have on people’s rights, and whether the system influences decisions (for example, hiring, credit, health, or diagnosis).
That basis is what allows you to design a governance plan in a structured way.
A minimum inventory of use cases (work template)
Before discussing “tools”, it helps to create a simple table:
- Use case name (what the system does in the business)
- Input/output (what data enters and what result comes out)
- Who decides (human-in-the-loop or not)
- Impact on people (if it affects rights, access to services, opportunities, health, etc.)
- Provider (if it is a third party) and basic contractual scope
That inventory does not replace legal analysis, but it prevents the discussion from staying abstract.
High-risk: why the documentation load becomes critical
When a system falls into the high-risk category, the company faces more demanding requirements.
This often translates into greater need for: technical documentation, conformity assessments, traceability and records, clear information for the user, and effective mechanisms for meaningful human oversight.
Although engineering produces part of the evidence, legal teams and DPOs must ensure that: documentation has purpose, traceability answers regulatory questions, and governance does not become a “repository” without coherence.
This is where teams that already work with accountability and records often add immediate value.
Documentation with purpose: questions legal teams must be able to answer
When you review a documentation package, make sure it “closes” with clear answers:
- what the system does and what it is for,
- what risks the organisation identifies and how it mitigates them,
- who supervises and how the system is corrected if something goes wrong,
- what information the end user receives and how they can exercise rights when applicable.
If documentation does not answer those questions, you likely have a governance gap—not “more PDFs”.
Foundation models and general-purpose: new questions for legal
Foundation models and general-purpose systems introduce an important nuance: many organisations do not “develop” the model, but they do integrate it via APIs, fine-tuning, or embedded components.
That can create obligations stemming from usage and from the operational context.
For legal teams and DPOs, additional questions appear: what representations the providers offer, how outputs are used downstream, and how traceability of data processing is controlled across the full workflow.
Instead of waiting for the technical team to solve “compliance” at the end, legal teams and DPOs should lead mapping uncertainties.
That way, documentation is not improvised at the finish line.
Contracting checklist (without replacing legal advice)
With providers of models or APIs, it often helps to align expectations on:
- service scope and usage limits,
- representations about compliance and updates,
- sub-processors and transfers (if applicable),
- records and cooperation in case of incidents,
- provider exit (what happens if you switch models).
The goal is not “to add beautiful clauses”.
It is to ensure the contract reflects how you operate in practice, and what evidence you can require.
AI Act and GDPR: they intersect, but they are not the same
The AI Act does not replace the GDPR.
But in real operations they touch.
The intersection usually shows up when there is: personal data use in training or inference, profiling and automated decision-making, impact assessments, and responsibilities toward providers.
At that point, the DPO is a natural “bridge”.
If you want a refresher on what the DPO role includes in the EU, review Data Protection Officer (DPO) Responsibilities in the EU.
And if you need guidance on when having an external DPO makes sense for governance and accountability, see who needs an external DPO.
The goal is to avoid duplication and contradictions.
To do that, you cannot rely on two separated lines of work.
You need explicit coordination between data governance and AI governance.
To keep the documentation and evidence coherent, you can use what should a GDPR audit include as a practical reference when mapping your privacy controls.
DPIAs and risk evaluations: avoiding duplication without losing rigour
When a system uses personal data, it is common to see assessment processes in privacy.
The key is to define which part the GDPR covers and which part AI governance covers—without creating two parallel universes that nobody maintains.
A useful approach is a control mapping: one risk, one owner, one evidence artefact, and a defined review periodicity.
How to make AI governance auditable
The practical question for a legal team and DPO is:
how do I turn these obligations into a process that survives product changes?
One way to structure AI governance without inventing from scratch is to lean on management system standards.
For example, you can use ISO/IEC 42001:2023 (AIMS) – AI management systems as a reference to organise responsibilities, documentation, and continuous evaluation.
It does not replace the law.
But it helps keep the work coherent, auditable, and maintainable.
Recommended routine: “light” quarterly review
You do not need an endless committee.
But you do need periodic, short reviews that answer:
- are there new use cases?
- did the provider or model change?
- were there incidents or internal regulatory feedback?
- did documentation and owners get updated?
That routine prevents governance from freezing at the launch moment.
How to coordinate with product, engineering, and procurement without turning legal into a bottleneck
The most common risk is not “not knowing the law”.
It is arriving too late in the decision cycle.
Define minimum “gates” (lightweight, but real)
You do not need to block every PR.
But it often helps to define moments when legal/DPO must be involved, no matter what:
- a new use case with personal data or automated decisions
- a change in the model or AI API provider
- expansion into new markets or sensitive segments
- integration into end-user flows (UX, messages, transparency)
The goal is to avoid the pattern “it is already in production, now we fix compliance”.
Procurement and vendor management: make evidence requirements clear
Legal can help standardise a minimum package of questions and clauses for AI providers.
It does not replace commercial negotiation, but it reduces improvisation when every purchase is a different world.
Common language between legal and technology
Much of the friction comes from vocabulary.
It helps to align on simple internal definitions: what counts as a “use case”, what counts as “personal data” in your specific context, what an “output” is and how you record it, and what “human oversight” means in your product.
That speeds up reviews and reduces misunderstandings in documentation.
A lightweight decision record
A short log of decisions (date, use case, conclusion, owner) helps maintain traceability without turning daily work into a courtroom.
It is especially useful when the product iterates quickly.
Mistakes that can slow you down
Treating the AI Act as an engineering-only issue
If legal and DPO are left out of the classification and documentation cycle, the result is often “evidence” without traceable responsibility.
The AI Act asks for coordination, not full delegation.
Not doing a real classification of uses
Classifying by hand at the end creates rework.
If you do not map use cases and impacts, you will not know which obligations apply—or which evidence will be missing during review.
Separating AI governance and GDPR without bridging
You can end up with procedures that say different things.
Fixing the issue requires connecting DPIA/risk management logic with the AI governance documentation and supervision cycle.
Forgetting contracts and vendor management with an AI focus
Governance does not live only in the system.
It lives in how you buy, integrate, and control providers and models.
If you do not bake that into design, documentation breaks the moment you change providers.

Frequently Asked Questions (FAQs)
It affects more areas than most people think. The AI Act requires the organisation to classify uses, document evidence, and supervise systems. That involves legal, risk, and data protection, not just engineering.
It also typically affects product (user messages, flows, transparency), sales (demo promises), and support (internal assistant usage), because regulatory risk does not live only in code.
First, map real use cases and how they impact people’s rights. With that basis, you can understand the associated classification and documentation obligations.
If you start with “buy a tool” without a use case map, you normally pay later with documentary rework and inconsistencies between teams.
It means more documentation requirements, more traceability, and more structured governance around meaningful human oversight and follow-up. Your team must ensure evidence has purpose and coherence.
In practice, it often means more reviews, more records, and more discipline in product changes, because each change can alter the risk profile.
They intersect around personal data, profiling, automated decision-making, and responsibilities toward providers. The goal is for documentation and evaluation cycles not to collide.
A useful approach is to treat the AI Act and the GDPR as two lenses on the same system: one lens is AI governance, and the other is rights and personal data processing, with a single “owner” for coherence across both.
Even if you do not develop the models, integrating them can create obligations depending on how you use them and the context in which you operate them. Legal teams and DPOs must ensure that provider traceability and safeguards are integrated into internal processes.
In many cases, the key work is limiting use, defining usage boundaries in the product, and documenting which data enters and exits the workflow.
By defining a route: map use cases, classify, organise documentation, and align responsibilities between legal, DPO, and technology. That way you avoid improvising at the end.
A pragmatic starting point is: minimum inventory, clear gates, review templates, and an update rhythm the team can maintain.
Even if the detail is handled by legal and DPO, management board leadership is often the one that sets priorities and resources. Without a clear “top message”, governance degrades into a “parallel project” that gets paused every time there is a release.
A simple pattern is that the board approves the inventory of use cases, the risk appetite, and the review calendar.
Next step
If you want to transform the AI Act into a governance plan that is maintainable, start with use cases and risk mapping.
The next operational step is usually agreeing a review calendar and a living inventory; without that, governance becomes outdated the moment the product changes.
Start small, but document it: a recorded decision today prevents endless debates tomorrow.
