I have had the same issue with a Sedo transaction. The buyer was notified by Sedo to create an account at the registrar to accept the push.
great! Just wanted to make sure that his is a possibility. I did find a list of exceptions allowed by them (see below), but there is no mention of what they do in each event. Thanks for answering my question
"Permissible reasons for a transfer rejection
The releasing provider can only reject a transfer due to one of the following reasons which have been passed as permissible by ICANN:
Proof of an attempt to defraud
Ongoing UDRP case
Judicial ruling which forbids a transfer
Substantiated doubts as to the owner/Admin-Câs identity
Non-payment of the domain in question
Rejection by the domain owner (email, fax)
The domain has a registrar lock on it
The domain was registered less than 60 days previously
The domain was transferred less than 60 days previously"
