Uniform Dispute Resolution policy
UDRP or Uniform Dispute Resolution policy defines how disputes over domain name registrations are resolved in the global top-level domains (.biz, .com, .info, .name, .net, and .org as well as .aero, .coop, and .museum). The UDRP includes a mandatory, non-binding, low-cost administrative procedure to resolve a certain set of claims . namely, claims of abusive, bad faith registration. This means a bad faith violation of someone else's trademark. In situations other than these, the UDRP provides that disputes must be resolved by traditional means such as voluntary negotiation and lawsuits. The UDRP is part of the Registration Agreement that Internet users sign to register domain names in the global top-level domains (TLD). The UDRP was adopted by ICANN on 26 August 1999. Implementation began when the final policy documents were approved on 24 October 1999. [Adapted from InterNIC FAQs]
