Check every statement that is true for your situation. A UDRP complaint must prove all three elements under Paragraph 4(a) of the policy; the weakest one defines the case.
Your mark rights
Element 1: the domain must be identical or confusingly similar to a mark you hold rights in.
The registrant has no legitimate stake
Element 2: you must make a prima facie case that the registrant lacks rights or legitimate interests.
Bad faith registration and use
Element 3: you must show the domain was registered and is being used in bad faith.
What this checks
Paragraph 4(a) of the Uniform Domain-Name Dispute-Resolution Policy sets three conjunctive requirements: confusing similarity to your mark, the registrant's lack of rights or legitimate interests, and bad faith in both registration and use. Panels at WIPO and Forum apply these mechanically: a complaint that fails one fails entirely, whatever the merits of the other two. The guide to filing a UDRP complaint covers the elements, providers, and fees in full.
Where the checker shows weakness, gather evidence first. Registration timestamps, observed site content, and sale offers all carry more weight than assertions. If the domain is actively deceptive rather than just held, a registrar abuse report may resolve it faster and without a filing fee. And when the registrant is reachable, a cease and desist letter can end the dispute outright, or produce a sale offer that itself evidences bad faith.
Questions about this tool
Three elements together: the domain is identical or confusingly similar to a mark you hold rights in, the registrant has no rights or legitimate interests in it, and the domain was registered and is being used in bad faith. Failing any one element loses the complaint.
No. It maps your answers to the structure of Paragraph 4(a) of the policy. Panels weigh the actual evidence (registration dates, observed content, correspondence), not self-assessed checklists. For anything disputed, consult trademark counsel.
Possibly. Panels accept proven common-law or unregistered trademark rights, but they demand evidence of established commercial use (sales figures, press coverage, market recognition), which is a higher bar than a registration certificate.
Bad-faith registration is normally impossible to prove for registrations that predate your rights. A narrow exception exists where the registrant demonstrably anticipated your mark, such as registering around a publicized launch or merger.
