I have a client whose former provider is telling her that she have to fill out a k+k application to have her domains moved to my hosting company. Where can she find that application. I've never heard about it before.
Is your customer German? In Germany there is a form called "KK-Auftrag" (KK=Konnektivitätskoordination). It is used to ensure that the domain owner agrees to transfer the domain. Therefore it must be signed by the domain owner.
