Another record year in UDRP filings

The CAC started to provide services in UDRP dispute resolution in 2009, which means we are starting our 15th year as a UDRP Provider.

In 2023 the CAC overcame another filing record with a total of 908 filed cases. We have published 803 panel decisions and dispute parties reached about 50 settlements.

We would like to thank all of our panelists for their shared effort, ICANN for the possibility of being a part of the UDRP world and also to all participants of UDRP proceedings for the constant feedback which helps us grow.

We hope to introduce credit card payments for domain name disputes this year and we are also looking forward to another Prague panelist meeting this year.

Stay tuned!

Summary of 2022….. welcome 2023

In August 2022 the CAC launched a new version of our online platform for UDRP disputes. In October other two platforms - for .EU and .CZ cases followed. We can gladly say that all the disputes now run in a new, modern environment. We continue the development process so the platforms can work even better!

The Panelist meeting in October 2022 presented a great opportunity to discuss important topics of domain name dispute resolution. We are glad to look back at such a successful event!

According to our records, we have also reached 700 hundred cases this year - to be specific, in 2022 the complainants initiated 728 cases with the CAC. We are thrilled that the CAC gained such a reputation that Trademark owners use our services more and more. We appreciate the trust and we are looking forward to future cooperation also in forthcoming years.

Updated version of the UDRP platform

Dear users,

the CAC has prepared an updated version of the UDRP platform. The platform not only changed the design but was developed to be more secure and user-friendly for you. That means that some functions of the platform are different. The principle of the dispute nevertheless stays the same.

If you wish to start a new dispute, please log in and create a new dispute. Your login details are the same as they were on the previous version of the platform.

If you have a pending dispute (started before Saturday 20th August 2022) Please use this link: where you will continue the proceedings on the previous version of the platform.

Should you have any concerns, or issues to resolve or need our assistance, please send us an email at or call + 420 222 333 350 or +420 602 446 697.

We will welcome your feedback on this new platform. Feel free to contact us.
