Due to the specifics of .ES domains imposed by the Registry, the option to modify contact information is not available on NityGity's side.
However, the contact details updates can be done directly on the Registry's side. Please follow the instructions below to be able to update contact information for your .ES domain:
1. Retrieve the registrant contact handle from the Whois:
https://www.nic.es/esnic/esn/verValidacionWhoisAction?dominio=yourdomain.es (yourdomain.es should be replaced with your actual domain name)
2. Request the respective password to be sent to the connected email address:
https://www.nic.es/sgnd/contacto/passRecoverInicializar.action?tContacto.nic
3. Log into the web interface using the Registrant contact handle received at the step 1 and the password from the email:
https://www.nic.es/sgnd/login.action?tipoContactoElegido=1&nivelDominio=2
4. Click on the Editar link in order to change the registrant details.
That's it!
