UDRP providers compared: WIPO, Forum, CAC and ADNDRC

A stranger holds the domain that matches your brand. You have trademark rights. You want the name transferred. The next question is not whether to file a UDRP complaint – it is where to file one, and the answer matters more than most brand owners expect.

The Uniform Domain-Name Dispute-Resolution Policy is administered by four ICANN-accredited providers: WIPO, the Forum, the Czech Arbitration Court (CAC), and the Asian Domain Name Dispute Resolution Centre (ADNDRC). All four apply the same three-element legal test under Paragraph 4(a) of the UDRP, but they differ in filing fees, panel appointment practice, language flexibility, and caseload. Owning the trademark does not guarantee a transfer – all three elements of the Policy must be proved on the facts, at whichever forum you choose.

This page compares the four accredited providers across every dimension that affects a filing decision, then offers a prose decision matrix for the most common situations.

Why provider choice matters under the UDRP

Every UDRP complaint lands at the same legal test, but the provider shapes the experience on either side of it. Forum filing fees, panel pools, language rulings, and procedural speed differ across the four bodies – and those differences can affect both the cost of the proceeding and the quality of the decision.

WIPO and the Forum together handle roughly 97% of all UDRP proceedings. That dominance is not accidental: both maintain large, publicly searchable decision databases, experienced case-management teams, and international panel pools that complainants and respondents have come to rely on. CAC and ADNDRC each occupy a niche – CAC on price, ADNDRC on geography – and understanding those niches is useful when the standard filing choice does not fit the facts.

What does provider choice not change? The substantive law. All four apply the UDRP and the Rules. A panel at WIPO applies the same Paragraph 4(b) bad-faith factors and Paragraph 4(c) safe harbors as a panel at ADNDRC. Panel discretion is always present, but the legal framework is uniform. The choice of provider is a procedural and tactical decision, not a way to obtain a different rule set.

In our practice, we evaluate provider selection at the outset of every UDRP matter. The right choice depends on the number of domains in dispute, the language of the registration, the budget for forum fees, and whether an expedited decision is needed. For most global .com disputes, WIPO is the default – but that default deserves scrutiny before each filing.

How do the four providers compare on fees, speed, and panel selection?

The table below sets out the key procedural and cost variables for each provider. All figures are drawn from published rate schedules; forum filing fees are a separate cost from legal fees, and the two should never be conflated.

Provider	Filing fee (1–2 domains, single panel)	Three-member panel fee	Standard timeline	Market share	Key characteristic
WIPO	USD 1,500	USD 4,000	~45–60 days	Dominant share	Largest panel pool; expedited option since March 2026; most cited database
The Forum	~USD 1,300	Higher; parties split if respondent requests	~45–60 days	Second largest	Strong US-brand complainant base; extensive decision archive
CAC (Czech Arbitration Court)	~USD 500–800	Higher by schedule	~45–60 days	Small niche	Lowest entry-level fee; primarily used for European disputes
ADNDRC	~USD 1,300	Higher by schedule	~45–60 days	Small niche	Focuses on Asia-Pacific complainants and registrants

All four providers apply the UDRP Rules and the standard 20-day response window from the date the case commences. The timeline varies in practice: procedural requests, supplemental filings, and requests for a three-member panel all extend it. None of the providers guarantees a specific decision date.

WIPO: the dominant global provider

WIPO is the World Intellectual Property Organization's Arbitration and Mediation Center, and it is the provider most brand owners reach for first. In 2025 WIPO administered 6,282 domain-name cases – a record – and over 25 years it has resolved more than 80,000 cases involving parties from 190 countries.

Why does that volume matter to a complainant? Because it translates into a searchable database of tens of thousands of decisions, spanning every major sector and every pattern of bad-faith registration. When we assess whether the facts of a new matter meet the Paragraph 4(b) threshold, that database is the primary analytical tool. The Forum has a comparable archive, but WIPO's is most frequently cited by panels across all four providers.

WIPO's panel pool is international and multilingual. Cases can proceed in languages other than English when the registration agreement was in another language – the complainant typically requests the language of the proceeding, and the panel rules. For cross-border cybersquatting disputes where the registrant and the mark owner operate in different jurisdictions, WIPO's procedural flexibility is a practical advantage.

Since 9 March 2026, WIPO has offered an expedited procedure. A single-panel case covering up to five domains can receive a decision in approximately one month. The complainant's fee for that track is USD 4,000 (USD 1,000 to WIPO, USD 3,000 to the panelist). A respondent may separately elect to expedite from the response stage for USD 2,500. Where the brand owner needs a fast resolution – an active counterfeiting campaign, for example, or a product launch that the cybersquatted domain is disrupting – the expedited track is worth pricing in at the outset.

WIPO also administers more than 87 ccTLD dispute procedures. If the infringement spans both a .com and a national zone for which WIPO is the designated provider, a coordinated filing strategy may be possible under one roof.

The Forum: the second provider and its distinct profile

The Forum (formerly the National Arbitration Forum) handles the second-largest share of UDRP caseload. Its filing fee begins at approximately USD 1,300 for one or two domains under a single-member panel – slightly lower than WIPO's standard rate, though the gap narrows at higher domain counts.

The Forum's decision database is substantial and widely cited. Its panelist pool skews toward North American practitioners, which can be relevant when the dispute involves US trademark law or a registrant operating primarily in the United States. Panels at both WIPO and the Forum apply the same UDRP, but the texture of the analysis – how panels read registrant intent, how they weigh the evidence of bad-faith use – can vary at the margins by panelist background. That is a factor worth discussing with counsel before filing.

The Forum's process mirrors WIPO's in most respects: the respondent has 20 days to answer, a single-member panel is the default, and either party may request a three-member panel. If the complainant asked for a single panelist but the respondent requests three members, the parties generally split the higher three-member fee. That split can meaningfully affect the cost calculation for a complainant who filed expecting the single-panel rate.

In a recent matter (a .com cybersquatting complaint against a US-based registrant, early 2026), we filed at the Forum for a brand owner whose trademark registration was US-based and whose evidence of bad-faith intent was concentrated in US-based conduct. The Forum's panel, drawing on a deep familiarity with that fact pattern, issued a transfer order within the standard window. The result was consistent with what a comparable WIPO filing would have produced – which reinforces the point that the substantive law is the same across providers.

CAC: the low-cost entry point for smaller matters

The Czech Arbitration Court's UDRP service offers the lowest entry-level filing fee of the four providers – approximately USD 500–800 for a single-panel case involving one or two domains. For a complainant with a straightforward cybersquatting claim and a constrained budget, that difference is material.

CAC is the least-used of the four providers by volume, and its decision database is correspondingly smaller. That is a double-edged consideration. Panels at CAC apply the same UDRP and consult the broader consensus view developed across all providers; the smaller database does not mean weaker decisions. But a complainant seeking the richest comparative precedent pool will find it at WIPO or the Forum.

CAC is headquartered in Prague and has historically handled a proportionally larger share of European disputes. For a European brand owner with a lower-value domain dispute – where the filing fee is a significant fraction of the name's commercial value – CAC can make the economics of a UDRP complaint viable when WIPO's fee would not.

What CAC cannot offer is WIPO's expedited track, the Forum's North American panelist depth, or ADNDRC's Asia-Pacific orientation. The choice of CAC is typically a price decision, and it is a legitimate one when the facts are clear and the budget is the binding constraint.

ADNDRC: the Asia-Pacific specialist

The Asian Domain Name Dispute Resolution Centre serves complainants and registrants in the Asia-Pacific region. Its filing fee for a single-panel, one-to-two-domain case begins at approximately USD 1,300, in line with the Forum. ADNDRC has offices in Beijing, Hong Kong, Seoul, and Kuala Lumpur, and its panelist pool reflects that geography.

For a dispute involving a registrant based in mainland China, South Korea, or Southeast Asia, ADNDRC's regional expertise can be an advantage. Panel familiarity with local registration practices, with the market context in which a domain was registered, and with the language of the registration agreement are all relevant to the bad-faith analysis under Paragraph 4(b).

ADNDRC's caseload is a small fraction of the global total, and its decision database is commensurately limited. As with CAC, panels draw on the consensus view across all providers when applying the UDRP, so the smaller archive is not a substantive disadvantage – but the comparative precedent depth is lower. Where an Asia-Pacific registrant is involved and the complainant has a relationship or familiarity with that region, ADNDRC is worth evaluating alongside WIPO.

We have advised brand owners to file at ADNDRC when the registrant and the conduct were concentrated in a single Asia-Pacific jurisdiction and a regionally experienced panelist was likely to add analytical value. In those cases, the fee parity with the Forum meant the decision was driven by geography and panelist pool, not cost.

What decides the outcome regardless of provider?

Provider selection is a tactical decision. The outcome of the case is decided by the three elements of Paragraph 4(a) – and those are the same at every forum. A complainant who cannot prove that the domain was registered and used in bad faith will lose at WIPO, the Forum, CAC, and ADNDRC alike.

The evidence that drives UDRP outcomes: a trademark registration predating the domain (or clear common-law use), proof that the registrant had knowledge of the mark at the time of registration, and conduct after registration that fits one or more of the Paragraph 4(b) factors – offering the domain for sale to the mark owner, parking it with click-through advertising that exploits the mark's goodwill, or using it to divert traffic to a competing site.

The myth worth addressing directly: owning the trademark does not guarantee a transfer. A complainant who registered a mark after the domain, or who cannot show the registrant targeted the mark specifically, faces a materially harder case on the bad-faith element. Panels look at whether the registrant knew of the mark at registration – and in most cases, that requires more than the existence of a registration certificate.

Conversely, respondents with a genuine claim to the name – registrants who were known by the domain name before notice of the dispute, who made a bona fide offering of goods or services, or who hold the name for legitimate noncommercial purposes – have the safe harbors of Paragraph 4(c) available at every provider equally. A well-documented response presenting those facts is the defense, wherever the complaint is filed.

If the complaint is brought in bad faith – to strip a legitimate registrant of a name the complainant cannot rightfully claim – the panel may make a finding of Reverse Domain Name Hijacking (RDNH). That finding carries no monetary penalty, but it is a reputational mark against the complainant and is recorded in the public decision database. We regularly advise registrants facing abusive complaints to build the RDNH record as part of the response strategy.

How to choose: a prose decision matrix for four situations

The right provider depends on the facts. Four situations cover most of what we see in practice.

Situation 1: A .com that is clearly cybersquatted, with a well-documented trademark, filed by a brand owner who needs the strongest precedent base and the option to expedite. File at WIPO. The USD 1,500 single-panel fee is the standard cost of entry. The database depth is unmatched, and the expedited track (USD 4,000, approximately one month) is available if urgency justifies the premium. This is the default for most global disputes.

Situation 2: The same facts, US-based registrant, US trademark, and a complainant who regularly files in the United States. WIPO or the Forum are both defensible choices. The Forum's fee is slightly lower for single-panel filings; its panelist pool has deep US-brand familiarity. The substantive outcome should not differ. The choice comes down to fee and counsel preference – and for a complainant who files frequently, consistency across a portfolio may favor one provider over the other.

Situation 3: A straightforward cybersquatting claim on a lower-value domain, where the filing fee materially affects the economics of filing at all. CAC at approximately USD 500–800 makes the proceeding viable when WIPO's USD 1,500 would not. The UDRP applies identically. If the facts are clear – identical mark, obvious bad faith, no credible safe-harbor argument – the smaller decision database at CAC is not a practical disadvantage.

Situation 4: The registrant is based in mainland China, South Korea, or another Asia-Pacific jurisdiction, and regional panelist familiarity matters. ADNDRC at approximately USD 1,300 brings a panel pool with direct experience of local registration practices. For a dispute where the registrant's market context is central to the bad-faith analysis – for example, whether a name registered in Chinese characters or a phonetic equivalent could plausibly target a foreign mark – regional expertise can add real value. WIPO is also a viable choice given its multilingual practice, and a discussion with counsel about panel assignment practices at each forum is worthwhile before filing.

Cross-zone considerations: when a UDRP complaint is not enough

The UDRP reaches .com, .net, .org, and other gTLDs where the registrar is ICANN-accredited. It does not reach every national zone. If the infringement spans a .com and a .uk, for example, the UDRP handles the .com – but the .uk requires a separate filing under the Nominet DRS (now administered by WIPO since 7 July 2026). The DRS test is an "abusive registration" standard with a "registered or used" abusively element – a lower cumulative bar than the UDRP's "registered and used in bad faith."

For a .eu domain, the procedure runs through the Czech Arbitration Court's ADR.eu platform, with its own eligibility requirements and remedy structure. A .de dispute has no UDRP equivalent; it belongs in the German courts, with a DENIC DISPUTE entry to block transfer while the claim is pursued.

Where the cybersquatting conduct is egregious and the brand owner wants monetary damages – not just the domain name – no UDRP provider can award them. The UDRP's only remedies are transfer or cancellation. A US anticybersquatting court action is the route to damages, handled with local litigation counsel in the relevant jurisdiction. In some cases, filing the UDRP first and then proceeding to court for damages is a coherent sequence. In others, the court action alone is more efficient.

We assess that cross-zone picture at the outset of every matter. A UDRP win on the .com that leaves a .uk or .eu registration in hostile hands is a partial result, and the strategy should account for all zones in which the mark is at risk.

COGNOMEN's approach to provider selection

COGNOMEN handles domain-name disputes exclusively. We recover, defend, and transact internet domains across generic and country-code zones, before WIPO, the Forum, CAC, ADNDRC, and national procedures, and in court where arbitration cannot reach. We act for brand owners, domain investors, and registrants – including respondent-side defense and RDNH findings.

On every UDRP matter, we assess the three elements, recommend the provider, and prepare the filing. Our fee for a UDRP complaint is indicative at USD 2,500–4,000 in legal fees, separate from the forum filing fee; the exact figure is set after a case assessment.
