FAQ: prove a legitimate interest in your .eu domain

FAQ: prove a legitimate interest in your .eu domain. UDRP and ccTLD domain recovery and defense across .eu. Email the firm to assess your case.

A .eu domain you registered in good faith is now the subject of a complaint filed through the ADR.eu platform. The complainant asserts trademark rights and demands a transfer. Your first question is the right one: can you prove a legitimate interest in your .eu domain — and what evidence is strong enough to make that case?

Under the .eu dispute procedure, a respondent defeats a transfer or revocation order by demonstrating a right or legitimate interest in the disputed name. The governing rules draw on concepts similar to Paragraph 4(c) of the UDRP — bona fide use before notice, a name by which the registrant is known, or legitimate noncommercial or fair use — but the .eu framework is administered through the Czech Arbitration Court's ADR.eu platform and applies its own eligibility rules. The critical difference from many national procedures is that .eu complaints may be based on a wider set of rights than registered trademarks alone, which cuts both ways: a complainant has more grounds, and a respondent has more avenues to contest standing.

This FAQ addresses the questions we hear most often from .eu registrants facing a complaint: what legitimate interest means, what evidence counts, who decides the dispute, and what realistic options exist if the case does not go your way.

When can I prove a legitimate interest in your .eu domain?

You can demonstrate a legitimate interest at any point up to the deadline for filing your response, and the earlier you begin assembling evidence, the stronger your position will be. Under the .eu procedure, a respondent who can show any one of several recognized grounds — bona fide use of the name in connection with an offering of goods or services before receiving notice of the dispute, being commonly known by the domain name, or a legitimate noncommercial or fair use without intent to mislead consumers or harm the complainant's reputation — stands on defensible ground.

Timing matters for a second reason. Evidence of use that pre-dates the complainant's trademark registration, or that pre-dates the complainant's first use of the mark in commerce, carries significant weight. We regularly advise registrants to pull business registration records, invoices, correspondence, web archive captures, and social media history from the period before the complaint arrived. The date-stamp is the argument. A registrant who has operated under a name for years before a complainant acquired trademark rights in a similar mark has a materially stronger record than one who registered the domain speculatively after the mark became well-known.

What if your use is genuine but modest — a personal project, a small business, a placeholder site? Panels have recognized that legitimate interest does not require commercial scale. The question is whether the use is real and consistent with the name, not whether it is profitable.

Who can prove a legitimate interest in your .eu domain?

Any natural person, company, or organization that holds a .eu domain and can point to a genuine connection between the name and a pre-existing right, business activity, or fair use is positioned to raise a legitimate-interest defense. The .eu registration rules have historically required an EU or EEA nexus for the registrant, which means the respondent is already a qualified holder under the registry's eligibility framework — a fact that itself supports the defense in context.

In our practice, we see three broad categories of respondent who succeed with a legitimate-interest argument. First, businesses or sole traders operating under a name that pre-dates or is independent of the complainant's mark. Second, individuals whose personal name, nickname, or established online identity corresponds to the domain. Third, registrants who hold the name as part of a legitimate portfolio — where the name describes a product category, a geographic term, or a common word with demonstrable commercial value unconnected to the complainant's brand.

A fourth category — registrants who acquired the domain through a secondary-market transaction — faces a harder path. Legitimate-interest arguments do not travel with a domain automatically. The respondent must show that their own use of the name, as distinct from any prior registrant's use, meets one of the recognized grounds. We have defended registrants in this situation, but the evidence burden is higher, and the case preparation must account for the full chain of registrations.

What evidence actually decides the outcome?

The weight of a legitimate-interest defense rests almost entirely on contemporaneous documentary evidence — records created before the complaint, not in response to it. Panels reviewing respondent submissions look for materials that independently corroborate the registrant's account of why they registered the name and how they have used it.

The most persuasive evidence typically falls into four categories. Trademark or trade name registrations in any jurisdiction that pre-date the complainant's rights are valuable, though not required. Business registration documents, VAT filings, company accounts, or sole-trader records that associate the registrant with the name carry weight. Web archive captures — particularly those showing active, on-topic use of the domain — provide a chronological record that is difficult to fabricate retroactively. And correspondence or contracts in which third parties refer to the registrant by the disputed name establish that the name belongs to the registrant in the relevant market, not merely on the registration record.

What weakens the defense? A domain registered shortly after a well-known mark received wide press coverage, pointing to a pay-per-click landing page with links to the complainant's competitors, or offered for sale at a price exceeding the documented cost of registration. Any one of those facts complicates an otherwise defensible record. Two or more together make a legitimate-interest argument structurally difficult to sustain.

Does ADR.eu or a court decide a .eu dispute?

The Czech Arbitration Court's ADR.eu platform is the primary forum for .eu domain disputes; it is an administrative procedure, not a court action, and its panelists are independent experts, not judges. The ADR.eu panel's power is limited to ordering transfer or revocation of the domain — there is no monetary remedy available through the procedure itself. If either party wants damages or a broader injunctive order, a national court is the appropriate venue, though the cost and complexity of litigation are substantially higher.

Courts in the EU member state where the complainant or respondent is domiciled may also have jurisdiction over .eu disputes, and a registrant who loses at ADR.eu is not necessarily precluded from challenging that outcome in court. However, the procedural interaction between an ADR.eu decision and subsequent court proceedings is governed by the applicable national civil procedure rules — which vary across the EU. We work with local litigation counsel in the relevant jurisdiction when court proceedings are warranted. The ADR.eu procedure is designed to be the faster, lower-cost path; it resolves the majority of .eu disputes without court involvement.

What if the registrant does not respond?

Failure to file a response is treated as a default. A defaulting respondent does not automatically lose — the panel still examines whether the complainant has met its burden on each element of the complaint — but the respondent loses the opportunity to contest the factual record the complainant presents. In practice, default significantly increases the likelihood of a transfer or revocation order, because panels have no contrary evidence to weigh.

This is a common and avoidable error. We have seen registrants assume that a complaint will fail on its own merits without a response, only to receive a transfer order that could have been defeated with straightforward documentary evidence. The response deadline under the ADR.eu procedure is fixed, and late submissions face an extremely high bar for acceptance. If you receive a complaint notification, the window to act is short.

Can the decision be appealed or challenged?

Under the ADR.eu framework, decisions issued by a single expert can be appealed to a three-member panel within a specified period set out in the procedure's rules. The appellate panel conducts a fresh review, but — as with comparable procedures in other ccTLD systems — the scope for introducing new evidence on appeal is constrained. The better approach is to build the complete legitimate-interest record before the first-instance decision, not to reserve it for appeal.

Separately, a registrant may challenge an adverse decision in the courts of a competent EU jurisdiction. EURid, as the .eu registry, will typically implement an ADR.eu transfer or revocation order unless a court issues a stay. Obtaining that stay requires prompt action and, in most cases, coordination with local litigation counsel in the relevant jurisdiction. The appellate ADR.eu route is generally faster and lower in cost than a court challenge, which is why the first-instance record matters so much.

What is the deadline once a case starts?

Once the ADR.eu procedure formally commences, the respondent has a fixed window to file a response — the exact period is set by the ADR.eu Supplemental Rules, and the current version of those rules governs. The general expectation across comparable procedures is that a respondent has roughly 30 days from commencement to file, though registrants should verify the current ADR.eu rules with counsel because procedural timelines are subject to registry amendment. Acting on the assumption that you have longer than you do is one of the most common errors we see.

The overall case timeline from filing to a first-instance decision is typically measured in weeks to a few months, depending on whether the matter proceeds as a default or a defended case. A complex defended matter with multiple submissions may take longer. Unlike the UDRP, where WIPO offers a roughly two-month standard timeline, the ADR.eu procedure has its own published timetable that the panel applies.

When does a complaint itself become an abuse — and can a respondent seek an RDNH finding?

Reverse Domain Name Hijacking — an RDNH finding — is available under the .eu procedure where the complainant filed the complaint knowing it lacked merit, or used the procedure to pressure a legitimate registrant into surrender. The finding carries no monetary penalty, but it is a formal, published record that the complainant acted in bad faith. For a registrant who holds a genuinely legitimate domain and faces a complainant that knows it lacks the evidence to win, pursuing an RDNH finding is a realistic objective.

The scenarios where RDNH is most realistic: the complainant's trademark post-dates the domain registration by years; the complainant's mark is geographically limited and the registrant's use is clearly in a different market; or the complainant made pre-complaint buy-back demands and then filed when the registrant declined. In a recent matter (a .eu complaint, autumn 2025), we defended a registrant who had held a descriptive domain for several years before a complainant acquired a later trademark and filed — the panel denied the complaint and noted the complainant's failure to address the registrant's prior use record.

RDNH is not a strategic tool to deploy routinely. It requires that the respondent's legitimate-interest record is clear and that the complainant's filing was genuinely without a plausible basis. But where those conditions are met, we press for the finding.
