When viewing the service contacts, you may see a contact added by a different party or the court to the case. If the contact was not added by you/your firm, you will only see the details without an option to edit the information.
Questions regarding the details entered on the contact (ex: email address for the contact, any administrative copy info, etc.) would need to be directed to the entity who added the contact.
Only the firm/person who added the contact is able to edit the contact information.
