Bravo Notes on Inter-Registrar Transfer
ICANN Transfer Policy (Effective as of 1 December 2016)

II. Inter-Registrant Transfer (Change of Registrant)
c. Change of Registrant Process
1.2 The Registrar must impose a 60-day inter-registrar transfer lock following a Change of Registrant, provided, however, that the Registrar may allow the Registered Name Holder to opt out of the 60-day inter-registrar transfer lock prior to any Change of Registrant request.
are many other similar references to such opt-out throughout the entire
document. I am convinced that ICANN has explicitly deemed that such
override (of the hold imposed) is at discretion of registrar.
