In filings from July 29, 2024 it is possible to pay the fees for domain name disputes via card!
Our platform cooperates with Global Payments secure payment gateway, enabling quick and easy card payment. There are no special fees for payment by card (the fee is the same as bank transfer).
We hope this new method will be more comfortable and quicker than a bank transfer.

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!
CAC ADR team
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.
CAC team
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: https://legacy-udrp.adr.eu 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 info@adr.eu 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.
Our ADR Team would like to wish everyone nice, calm and peaceful holidays! Let this holiday season be the restart we all need to jump right into the year 2024 and make it even better than this one!
CAC´s offices will work in a limited regime during holidays, on Friday, December 22, 2023, and between December 27 and 29, 2023, the offices will close at 1 p.m.
Thank you for your understanding and cooperation!
Have a great Christmas!

The year 2020 was challenging in all aspects of our lives. Despite the pandemics, the UDRP services stayed functional during the lockdowns and other obstacles. That was mainly because the whole proceeding takes place online via this platform!
There is a positive outcome of 2020 – the dispute statistics which show a big (and yet stable) growth of domain name disputes in UDRP. See the chart here: UDRP - domain names
Due to basic service of our platform there will be a temporary outage of platform on Friday, August 16, 2019 from 16:00 to Saturday, August 17, 2019 16:00.
Thank you for your understanding,

The Czech Arbitration Court ("CAC") is organising a Panelist meeting for UDRP, .EU and .CZ Panelists and Experts. The meeting will take place at the Kaiserstein Palace, Prague, on 23rd September 2019. Please find enclosed programme for more information. The presentations will focus on current problematic topics and the CAC hopes that the discussion to this topics will be helpful in its further activities.
There have been a few minor changes to increase the security of our online platforms. Because of these adjustments, you may need to set up new login information in accordance with the new security policy.
Should any modifications to the platform cause you any technical difficulties, please contact us via email info@adr.eu, we will be happy to assist you.
Thank you for your understanding,
ADR team
Please note that as The General Data Protection Regulation (GDPR) takes full effect since 25 May 2018 across the EU countries, ICANN releases the Temporary Specification for gTLD Registration Data establishing temporary requirements to allow ICANN and gTLD registry operators and registrars to continue to comply with existing rules in light of the GDPR. The Temporary specification states, regarding UDRP, besides other, in Apendix E article 1.2 that: „Complainant's complaint will not be deemed defective for failure to provide the name of the Respondent (Registered Name Holder) and all other relevant contact information required by Section 3 o the UDRP Rules if such contact information of the Respondent is not available in registration data publicly available in RDDS or not otherwise known to Complainant. In such an event, Complainant may file a "Doe" complaint and the Provider shall provide the relevant contact details of the Registered Name Holder after being presented with a "Doe" complaint.“
Please be aware that there will be update in the CAC UDRP fees applicable from February 1, 2018 (i.e. on complaints that will be delivered to the CAC on or after February 1, 2018). Structure of the split fee will remain and the initial fee will increase in most of the cases and the additional fee will decrease. This fee schedule reflects more the actual costs and time spent on the proceedings. Please see the new fees schedule for more details.
The Czech Arbitration Court ("CAC") is organising a Panelists meeting for .EU (and .EЮ), UDRP and .CZ Panelists and Experts. The meeting will take place at the Kaiserstein Palace, Prague, on 18 September 2017, however there will be also informal part of the meeting on 17 September 2017. Please find enclosed the programme for more information. The CAC looks forward to meet again with its Panelists and Experts in Prague and looks forward to interesting presentations and discussions on current issues related to domain name disputes.
There will be a conference for ADR.eu and UDRP panellists held in Kaiserstein Palace, Prague, on Friday 25th September 2015, jointly organised by Palmer Biggs Legal Solicitors (UK), Ampersand Law Firm (Germany) and the Czech Arbitration Court. Please find the programme enclosed. We expect around 35 panellists from all over the world to attend. Some of the panellists will have been already present by Thursday 24th September for dinner at a typical Czech restaurant. Some of the panellists decided to stay until Saturday to join a walk through Prague.

As of 26 February 2013 the Czech Arbitration Court operates as a .sx domain name dispute resolution provider appointed by SX Resgitry SA, the .SX registry. The .sx disputes are conducted under UDRP Policy and Rules. These disputes are decided by UDRP Panellists.
As of 1 November 2011, the Czech Arbitration Court will cancel the possibility of filing UDRP complaints and responses using the Chess Cards. Those who were issued a Chess Card will no longer be able to use it to make a UDRP filing with the Czech Arbitration Court, however their user accounts created by registration made on the online platform will not be affected by the change and they will be able to continue to make their UDRP filings without using the Chess Cards.
We are pleased to inform you of the results of the user survey we have made in the end of 2010 amongst the users of our online platform. The participants were posed 5 questions regarding the functioning of the platform, the quality of the information published and the communication with the CAC. Please find the answers below:
| 1. Did you find using the platform easy? | |
| a) easy | 77% |
| b) acceptable | 19% |
| c) I had difficulties using the platform | 4% |
| 2. Have you found enough information on the website? | |
| a) quite enough | 73% |
| b) the most important issues were covered | 23% |
| c) not enough | 4% |
| 3. Was the communication with the ADR Center smooth? | |
| a) smooth | 73% |
| b) without difficulties | 23% |
| c) I had difficulties communicating with the CAC | 4% |
4. What improvements of its services would you recommend the CAC to make? We have received 11 specific comments most if which were already implemented to increase quality of the platform.
We are still working on improvement of our services and welcome any comments or suggestions you might have about it.
As we have announced earlier, as of Monday 1 March 2010 we will implement the e-UDRP. Parties filing their Complaints or Responses will no longer be obliged to submit a hardcopy of their filing or use a Chess Card. However, using the Chess Card remains available to those who wish to have their electronic filings authenticated in a similar way as handwritten signature authenticates hardcopy documents. These changes do not require any modification of our UDRP Supplemental Rules.
In addition, the CAC has implemented a new feature of the online platform that will facilitate filing a Complaint – a Registrar database. From now on the Complainant does not have to search for the identification of the Registrar to be able to file a Complaint properly. It will be able to choose a name of the Registrar from the drop down menu instead and the other contact details will be prefilled automatically (postal and e-mail address, phone number, etc.).
As of 1 March 2010, the ADR.EU Center of the Czech Arbitration Court will not require the use of Chess Cards for electronic only UDRP filings. Parties to a UDRP dispute will continue to be able (but not obliged) to use their Chess Cards for increased authentication of their electronic filings. ADR.EU will still require as a minimum on-line security tool that the parties of a UDRP proceeding register themselves on the UDRP on-line platform (udrp.adr.eu) and receive their unique username and password.
This relaxation of conditions for electronic-only UDRP filings follows recent decision of ICANN Board to amend the UDRP Rules and enable electronic-only UDRP (see the ICANN announcement).
In the autumn of 2009 we published for public consultation (http://adr.eu/arbitration_platform/public_consultations.php) our proposal for the Expedited Decision which has been the subject of much discussion amongst the Internet Community. One of the criticisms of that proposal is that it introduces a dual-track UDRP that is not permitted under the Policy and Rules.
We do not agree with this criticism but this is not the key aspect of the proposal. The core of our proposal is the introduction of a substantially lower filing fee for simple cases where no response is filed and there is no need for Panellists to produce a detailed decision.
ADR.EU has therefore decided to remodel our proposal to concentrate on this core idea. We attach a changed Fee Schedule which will become effective as of 15 March 2010. There will be no check-box decisions and the same decision form will apply for all the decisions – see attached. We anticipate that UDRP decisions in simple cases where no response is filed will be quite short and will just outline reasons for the decision. Model forms of decisions in simple cases and in other than simple cases will be put prominently on our on-line platform as guidelines for our Panellists.
Panellists will also retain an absolute discretion even in cases where no response has been filed to notify ADR.EU that the proceedings are such that a more detailed decision is required and to require payment of the additional UDRP fee (see the attached proposed new Fee Schedule) in view of - inter alia - the complexity of the legal arguments, the length of the complaint or the amounts of exhibits to review.
As a separate exercise we will also modify, as of 15 March 2010, certain parts of our standard complaint and response forms which appear on our on-line platform – see also attached documents. Our aim is to make it easier for complainants and/or respondents to file their submissions on our UDRP on-line platform. These forms will be complemented by additional explanatory notes on the on-line platform.
The Czech Arbitration Court has decided to lower its fees for .eu domain-name disputes so that the fees for both its ADR and UDRP procedure were the same. Please click here to see the details.
As of 6 May 2009 the Czech Arbitration Court operates as a .co.nl domain name dispute resolution provider appointed by EuroDNS S.A., the CO.NL Operator. The .co.nl disputes are conducted under UDRP Policy and Rules. These disputes are decided by UDRP Panellists.
Our Pilot project related to new electronic UDRP services has ended and the piloted electronic services are temporarily suspended pending the resolution of ICANN Board on the Pilot. We hope that ICANN Board will consider our Pilot soon.In the meantime you can still file your UDRP Complaints/Responses in a standard way (in hardcopy and in electronic form).
We are delighted to present you an easy and flexible possibility how to familiarize yourself with our new UDRP on-line platform.
You can access our Test Platform which is available on: http://udrp.expert4me.com/. All you need to do is to click onto the on-line platform in the main menu, register your name and details and then follow the instructions.
If you have any technical difficulties, please contact the UDRP Support Team who you can reach by e-mailing support@expert4me.com.
There are several important points to note about the Test Platform:
In addition to your testing our Test Platform you can participate in one of our training webinars – please click on the section Webinars in the left-hand menu to know when will the webinars be organized and how to register for them.
The Czech Arbitration Court (CAC) is launching its Uniform Dispute Resolution Policy (UDRP) service on 12 January 2009 by running two initiatives designed to streamline the process and to save complainants and respondents both time and money. The CAC’s UDRP Service is available at udrp.adr.eu .
In January 2008 ICANN, the Internet Corporation for Assigned Names & Numbers, approved the CAC application to become an international provider of UDRP services. CAC has then undertaken a 10 month consultation of intellectual property owners and the legal representatives of both complainants and respondents.
The UDRP features an expedited procedure that is mandatory upon all registrants of generic Top Level Domains including .com, .org, .net, .biz, .info and .mobi. It is designed to settle disputes arising from the abusive registration of domain names.
The foundation of CAC’s UDRP service is a unique electronic platform that could revolutionise the process of filing a complaint. This platform will incorporate the results of two test projects using trial data that have been running across five continents during December 2008 featuring:
After the tests, a formal Pilot Programme, open to all interested parties who can file complaints using Partial or full e-filing will run from January – March 2009. The results of the Pilot will be presented to ICANN for consideration.
Zbynek Loebl, head of the UDRP Implementation Team for the CAC which is a non-profit organisation based in Prague, said, “Our aim is to lessen the burden on both complainants and respondents by utilising the functionality of the internet. The preparation of a UDRP complaint or response is cumbersome and time-consuming. Currently at least four copies must be prepared and sent out by registered courier. We believe that e-filing will reduce the administrative burden and cut costs without compromising security. We are grateful to ICANN for being open to our aim and we are pleased that other UDRP providers are considering the benefits of e-filing”.
An additional innovative feature of the CAC’s UDRP service is the option for Class Complaints with the filing of a single complaint on behalf of multiple complainants. Vit Horacek, CAC’s Board member responsible for the UDRP implementation said, “We believe that the option of a Class Complaint could be very attractive to trade mark owners who wish to tackle serial cybersquatters who focus on a business sector”.
The CAC is glad to announce that persons who file the first three UDRP complaints on the CAC’s on-line platform (starting on 12 January 2009 at udrp.adr.eu) will be awarded electronic-only gold, silver and bronze medals respectively, accompanied by small hard-copy gifts.
