Important

Starting with 2025, IISE Registry is no longer requiring documents for Ownerchange, instead they are requiring the ICANN Ownerchange process. The process has been enabled, and it is built at CentralNic Reseller in the same way as for any other gTLD, with the exception that Designated Agent Mode is not accepted. Details can be found here.
