Overview

This FAQ explains the Data Act rules on unfair contractual terms in business-to-business data contracts. It focuses on Article 13: when a data-related clause is treated as unilaterally imposed, which terms are always unfair, which terms are presumed unfair, what remains outside the unfairness test, and what contract review evidence teams should keep.

12 of 12 questions
Question 1

What does Article 13 of the EU Data Act do for B2B data contracts?

The Data Act context is the starting point for this answer. Article 13 protects one enterprise from unfair data-related contract terms unilaterally imposed by another enterprise. The rule covers terms about access to and use of data, and terms about liability and remedies for breach or termination of data-related obligations.

If the term is unfair under Article 13, it is not binding on the enterprise on which it was imposed. The rest of the contract can still bind the parties if the unfair term can be severed from the remaining terms.

  • Use Article 13 for B2B terms about data access, data use, liability, remedies, breach, or termination of data-related obligations.
  • Do not treat Article 13 as a general review of every commercial clause; the term must be data-related in the Article 13 sense.
  • Record whether the challenged clause was imposed on one enterprise by another and whether it can be severed from the contract.

Question 2

When is a Data Act contract term considered unilaterally imposed?

The Data Act context is the starting point for this answer. A term is treated as unilaterally imposed when one contracting party supplied it and the other party could not influence its content despite trying to negotiate it. This is the practical issue behind take-it-or-leave-it data access and data use clauses.

The party that supplied the contested term bears the burden of proving that it was not unilaterally imposed. The same party cannot use Article 13 to argue that its own supplied term is unfair.

  • Keep the proposed template clause, negotiation comments, redlines, rejection emails, and fallback positions.
  • Mark whether the counterparty actually had a realistic chance to change the data-related term.
  • For standard templates, distinguish terms that were merely accepted from terms that were genuinely negotiated.

Question 3

What is the general unfairness test under Article 13 under the Data Act?

The Data Act context is the starting point for this answer. The general test is whether the term grossly deviates from good commercial practice in data access and use, contrary to good faith and fair dealing. That test matters for terms not already captured by the Article 13 always-unfair or presumed-unfair examples.

A practical review should compare the clause against the Data Act purpose of fair data access and use, the parties' bargaining position, the data involved, the impact on legitimate interests, and the remedies available if obligations are not performed.

  • State the clause text and the data-related obligation it affects.
  • Explain the commercial impact on the enterprise that did not supply the term.
  • Record whether the clause blocks access, use, remedies, termination, data copies, or reasonable control of generated data.

Question 4

Which Data Act terms are always considered unfair for Unfair Contractual Terms implementation evidence?

The Data Act context is the starting point for this answer. Article 13 lists three types of terms that are unfair where their object or effect matches the list. These are the closest equivalent to a black-list review for B2B data contracts.

The always-unfair examples cover terms that exclude or limit the imposing party's liability for intentional acts or gross negligence, remove remedies for the enterprise on which the term was imposed, or give the imposing party the exclusive right to decide data conformity or interpret the contract.

  • Flag any clause that limits the imposing party's liability for intentional acts or gross negligence.
  • Flag any clause that removes remedies for non-performance or breach of data-related obligations.
  • Flag any clause giving the imposing party sole power to decide whether supplied data conforms to the contract or what a term means.

Regulation (EU) 2023/2854 (Data Act)

Article 13(4) identifies terms that are unfair because of their object or effect, including liability exclusions, remedy exclusions, and exclusive interpretation rights.

Question 5

Which Data Act terms are presumed to be unfair for Unfair Contractual Terms implementation evidence?

The Data Act context is the starting point for this answer. Article 13 also lists terms presumed unfair. These are not automatically final in the same way as the always-unfair terms: the party that imposed the term can try to show that the term is not unfair.

The presumed-unfair group includes inappropriate limits on remedies or liability, harmful access to or use of the other party's data, preventing the other party from using data it provided or generated, blocking termination within a reasonable period, blocking a copy of provided or generated data, termination at unreasonably short notice, or substantial unilateral changes to price or data-sharing conditions without a valid reason and termination right.

  • Review remedy caps, liability extensions, data-use rights, termination rights, copy/export rights, notice periods, and unilateral change clauses.
  • Pay close attention to commercially sensitive data, trade secrets, and intellectual property rights when the imposing party claims broad access or use rights.
  • If the term is only presumed unfair, keep the imposing party's written justification and the reasons it does or does not overcome the presumption.

Regulation (EU) 2023/2854 (Data Act)

Article 13(5) lists presumed-unfair terms, including remedy limits, harmful data use, blocked data use, blocked copies, short-notice termination, and unilateral changes.

Question 6

Are price and main-subject-matter clauses reviewed under the Data Act unfair-terms rule?

The Data Act context is the starting point for this answer. Article 13 does not apply to terms defining the main subject matter of the contract or to the adequacy of the price as against the data supplied in exchange. That exclusion should be recorded before treating a pricing or core-scope clause as an Article 13 unfair term.

The exclusion is narrow in practice. A price number or core data-sharing description may sit beside other reviewable terms, such as unilateral changes to price, format, quality, quantity, termination, remedies, or copy rights.

  • Separate the main subject matter and price adequacy from surrounding data access, use, remedy, and unilateral-change clauses.
  • Do not use the exclusion to ignore a data-related remedy, liability, termination, or unilateral change term.
  • Keep the review note short: excluded under Article 13(8), reviewable elsewhere, or not an Article 13 issue.

Question 7

When do the Data Act unfair-terms rules apply to new and older contracts?

The Data Act applies from 12 September 2025, and Chapter IV applies to contracts concluded after 12 September 2025. Older contracts concluded on or before 12 September 2025 enter Chapter IV from 12 September 2027 only if they are of indefinite duration or are due to expire at least 10 years from 11 January 2024.

For contract operations, keep a contract population view that separates new contracts, renewals or amendments, indefinite-duration contracts, and very long-running older contracts. Do not apply the older-contract rule to every legacy agreement without checking the duration criteria.

  • Record contract signature date, renewal or amendment date, expiry date, and whether the contract is indefinite.
  • Flag post-12 September 2025 templates for Article 13 review before signature.
  • For older contracts, flag only indefinite-duration contracts and contracts due to expire at least 10 years from 11 January 2024 for the 12 September 2027 Chapter IV review.

Question 8

How do SMEs and larger enterprises fit into the unfair-contract-terms review under the Data Act?

The Data Act context is the starting point for this answer. Chapter IV is framed as protection for all businesses, with particular relevance for SMEs facing stronger bargaining positions in data-sharing negotiations. Article 13 itself applies to an enterprise on which a covered unfair term has been unilaterally imposed by another enterprise.

SME status is still operationally important. The Commission says the model contractual terms were developed to help parties, especially SMEs, implement the Data Act, and the Data Act explainer highlights Chapter IV as a tool against stronger parties imposing non-negotiable data access and use terms.

  • Capture whether the party receiving the term is an SME, but do not assume Article 13 is limited to SMEs.
  • Use bargaining position, template control, and negotiation evidence to assess unilateral imposition.
  • When an SME receives a take-it-or-leave-it data clause, prioritize review of liability, remedies, data-use restrictions, data-copy rights, termination, and unilateral-change language.

Question 9

How should teams use the Commission model contractual terms with Article 13 under the Data Act?

The Commission model contractual terms are voluntary tools, not a replacement for Article 13. They can help draft Data Act data-sharing contracts and benchmark whether a clause structure is aligned with fair, reasonable, and non-discriminatory rights and obligations.

The Commission source says the model contractual terms for Data Act data sharing are compliant with Chapter IV on unfair contract terms. Teams should still adapt them to the actual data-sharing relationship and keep a clause-by-clause rationale when changing them.

  • Start with the relevant relationship: data holder to user, user to data recipient, data holder to data recipient, or voluntary data sharer to data recipient.
  • Document any departure from the model term where the change affects access, use, remedies, liability, termination, compensation, or trade secret protection.
  • Do not present model terms as mandatory; keep the Article 13 fairness review separate from the decision to use model wording.

Question 10

What evidence should a Data Act unfair-terms contract review keep?

The Data Act context is the starting point for this answer. Keep enough evidence to show the clause text, who supplied it, whether the other party tried to negotiate it, the data-related obligation affected, the Article 13 category considered, and the final outcome. The file should let a later reviewer distinguish a negotiated clause from a unilateral template clause.

For practical contract review, use a matrix with fields for clause location, data type or dataset, contract relationship, Article 13 category, always-unfair or presumed-unfair flag, negotiation evidence, fallback wording, approver, and date. Add model-term comparison where the Commission wording was used or intentionally changed.

  • Retain clause versions, comments, counterparty objections, internal approvals, and final signed wording.
  • Record whether the term was removed, rewritten, justified, severed, or left because Article 13 did not apply.
  • Link the review to the contract population so older qualifying agreements can be found without repeating the whole analysis.

Question 11

What Data Act source evidence should teams keep for the Unfair Contractual Terms FAQ decision?

Keep the legal basis and the decision trail together. For Article 13 work, the record should cite the Data Act source clause, the specific Article 13 paragraph used, the Commission guidance or model-term reference relied on, and the contract version that was reviewed. That makes it clear why a term was treated as unilaterally imposed, always unfair, presumed unfair, or outside the scope of Article 13.

Teams should also retain the implementation artifact that shows how the decision was applied in practice, such as the redlined contract, review memo, approved template, or deviation note.

  • Keep the cited Data Act article text, the source URL, the review date, and the reviewer or approver.
  • Store the clause draft, final wording, and any negotiation evidence together with the implementation artifact.
  • Note whether the outcome was removal, severance, rewrite, or no change because the clause fell outside Article 13.
Question 12

How should teams assign ownership for Data Act Unfair Contractual Terms implementation work?

Assign one accountable owner who can change the contract or workflow affected by Article 13. For a Data Act unfair-terms review, that is usually the legal or commercial lead for the contract, with procurement, product, cloud, support, or security teams consulted where their process is affected.

For implementation, ownership should track the action: one owner for template updates, one owner for contract review approvals, and one owner for operational follow-up on the workflow or system that uses the clause. That avoids a generic checklist and makes the decision executable.

  • Name a single accountable owner for each Article 13 action, such as template update, deal review, or process change.
  • Record the affected workflow, the evidence artifact, and the review trigger beside the owner.
  • List consulted teams separately so accountability stays with the team that can actually make the change.
