UDRP - Uniform Domain-Name Dispute-Resolution Policy
http://www.icann.org/en/udrp/udrp.htm

·         All registrars must follow the Uniform Domain-Name Dispute-Resolution Policy. Under the policy, most types of trademark-based domain-name disputes must be resolved by agreement, court action, or arbitration before a registrar will cancel, suspend, or transfer a domain name.

·         Disputes alleged to arise from abusive registrations of domain names (for example, cybersquatting) may be addressed by expedited administrative proceedings that the holder of trademark rights initiates by filing a complaint with an approved dispute-resolution service provider.
