Which UDRP provider should you file with?

A stranger holds the domain that matches your brand and is asking a five-figure sum to hand it over. You have a trademark, you have the evidence, and you want to file a UDRP complaint – but four accredited providers exist, and choosing the wrong one wastes money and time. Which UDRP provider to file with is not a purely strategic question: fee, language, panel depth, and domain count all point toward different answers.

The four UDRP providers are WIPO, the Forum, the Czech Arbitration Court (CAC), and ADNDRC. Together, WIPO and the Forum handle roughly 97% of all UDRP proceedings. WIPO is the default choice for international parties and multi-language matters; the Forum is a cost-competitive US-market alternative; CAC offers the lowest entry-point fee; and ADNDRC serves Asia-Pacific parties. A standard WIPO single-panel complaint costs USD 1,500 in filing fees and normally concludes within about two months.

The decision tree below walks you through the four deciding factors – domain count, language, panel preference, and budget – and returns a provider recommendation with the relevant filing fee. Read the explanatory sections that follow to understand why the tree routes the way it does.

How does the decision tree work?

The tree asks four questions in sequence. Each answer narrows the field until one provider fits your situation. The questions mirror the analysis a practitioner runs when a new file lands on the desk: how many domains are in dispute, what language is preferred, does the matter warrant a three-member panel, and what is the filing-fee budget? Owning a trademark does not guarantee a transfer – the panel still applies all three elements of Paragraph 4(a) to your specific facts – but choosing the right forum at least avoids procedural friction before the analysis begins.

Fees stated are the published rates as of August 7, 2026; confirm current rates before filing. Legal fees are separate from all figures above. See cognomenlaw.com/fees.html for COGNOMEN's indicative legal fees.

What are the rules and fees behind this tool?

Every figure in the tree is drawn from the providers' own published schedules. WIPO's standard single-member-panel fee for one to five domains is USD 1,500; a three-member panel at the same volume costs USD 4,000. For six to ten domains those fees rise to USD 2,000 and USD 5,000 respectively. Above ten domains WIPO prices by quotation. The Forum's entry point sits at approximately USD 1,300 for one to two domains on a single panel. CAC's entry point is approximately USD 500–800, making it the lowest-cost option, though its smaller panel pool and lower usage volume are factors practitioners weigh against the saving. ADNDRC's entry-point fee is approximately USD 1,300, aligned with the Forum.

WIPO and the Forum together account for roughly 97% of all UDRP proceedings – a concentration that reflects panel depth, institutional familiarity among registrars, and procedural predictability. A registrar implementing a transfer order from either provider does so as a matter of standard workflow; an order from a less-used provider is equally valid, but the registrar's compliance team may require more time.

WIPO introduced an expedited procedure on 9 March 2026. For single-panel cases covering up to five domains, the expedited track delivers a decision in approximately one month. The complainant pays 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. The standard track remains available at the existing USD 1,500 fee; the expedited option is an addition, not a replacement.

WIPO also published its refund policy on 9 March 2026. A complaint withdrawn before formal notification is refunded except USD 100 (for one to five domains). A case terminated after formal notification but before panel appointment is refunded except USD 500. After panel appointment, no refund is issued. These are WIPO's published refund terms as of March 2026.

How do language and panel composition affect the choice?

The UDRP requires proceedings to be conducted in the language of the registration agreement unless both parties agree otherwise or the panel orders a change. For a domain registered under a Chinese-language agreement, proceedings default to Chinese. WIPO administers cases in a wide range of languages and has the deepest multilingual panel roster of any provider. If the registration agreement is in a language other than English and you cannot reach a consent-to-English agreement with the registrant, WIPO is effectively the only practical option among the four providers for maintaining procedural momentum.

Three-member panels are more expensive – the parties generally split the cost when the respondent requests the upgrade – but they reduce the risk of a single eccentric decision and are conventionally preferred where the legal or factual questions are close. A matter involving a long-established generic term, a descriptive mark, or a registrant with a credible fair-use argument is exactly the profile where a three-member panel earns its additional cost. WIPO's three-member roster is the largest. The Forum's is also substantial. CAC and ADNDRC operate three-member panels but have smaller rosters.

In a matter we handled in early 2026 – a .com dispute in which the registration agreement was in Spanish and the registrant had held the domain for several years – WIPO's language capability was the deciding factor in forum selection. The complainant filed in English with a simultaneous request to proceed in that language; WIPO granted it after reviewing the registrant's correspondence, and the case proceeded without the translation overhead that would have arisen at a provider with a narrower language infrastructure.

What does the tool not tell you?

The decision tree selects a provider. It does not assess whether your complaint will succeed. A UDRP panel at any of the four providers applies the same Paragraph 4(a) test: confusing similarity, no legitimate interest, and registration and use in bad faith. The provider choice affects cost, timeline, and procedural language – not the substantive standard. Owning a trademark does not guarantee a transfer. The bad-faith element in particular turns on specific evidence: the content of the disputed website, the circumstances of registration, the registrant's conduct before and after the dispute, and the chronology relative to your trademark rights.

The tree also does not account for cases where the zone itself changes the analysis. If the disputed domain is a .uk, a .eu, or a .de, the UDRP does not apply and neither do any of the four providers in this tool. The Nominet DRS governs .uk; EURid's ADR.eu procedure governs .eu; .de disputes proceed through the German courts. The tool is calibrated for gTLDs (.com, .net, .org, and others) and for ccTLDs that have adopted the UDRP, such as .me and .tv. For any zone not confirmed as UDRP-enabled, verify the governing national procedure with counsel before selecting a provider.

The tool does not address what happens if the respondent files an identical or similar complaint in a different zone simultaneously, or if the registrant has used privacy or proxy registration to obscure their identity. Identifying a registrant now typically requires an RDAP lookup plus a disclosure request under ICANN's Registration Data Request Service (RDRS) – and the registrar's response time is outside your control. Those facts-of-record questions shape the complaint, not just the provider selection.

How does provider choice interact with the three UDRP elements?

Panel consensus within any given provider is a real phenomenon. Practitioners observe that certain fact patterns – passive holding, typosquatting, pay-per-click parking against a well-known mark – attract consistent findings across all four providers. On harder questions, such as whether a registrant's descriptive use constitutes a bona fide offering under Paragraph 4(c), panel-level variation exists within every provider's roster. Choosing a provider with a deeper panel pool does not guarantee any particular panelist is assigned.

What the provider does control is procedural predictability. WIPO has published a Jurisprudential Overview that consolidates panel consensus positions; practitioners at every forum cite it. The Forum has issued its own precedential guidance. CAC and ADNDRC follow the same Policy and Rules but have smaller bodies of publicly searchable decisions. For a dispute at the margins – close on the legitimate-interest element, or where the registrant is likely to file a vigorous response – a provider with deeper precedent depth offers more ground for briefing and panel analysis.

In a second matter from autumn 2025 – a .com dispute involving approximately a dozen related domains registered by the same entity – we selected WIPO specifically because the consolidated filing covered multiple registrations and the complainant's primary trademark was registered in a non-English jurisdiction. WIPO's ability to handle a consolidated multi-domain complaint with non-English trademark documentation in a single proceeding was the determinative factor.

What should you do with the provider the tree recommends?

The tree result is a starting point, not a filing instruction. Before submitting, verify three things. First, confirm that the provider's current filing fee matches the figure shown – rates are as of August 7, 2026, and can change. Second, check that the registrant is the same holder across all domains if you are filing a consolidated complaint; a single complaint covering domains held by different registrants is procedurally defective. Third, confirm that the zone is UDRP-enabled with the relevant registry before investing in the complaint preparation.

Once the provider is confirmed, the practical preparation is the same regardless of forum: a clear showing on all three Paragraph 4(a) elements, organized evidence of bad faith (screenshots, WHOIS/RDAP records, registration date relative to trademark priority, and any communications from the registrant), and a concise response to the most likely safe-harbor arguments. A well-drafted complaint at the right provider is faster and cheaper than a poorly drafted one at the cheapest provider.
