Trying to remember how long that usually takes, can't be too long? Maybe a week? Two?
From this on Wigan it looks like it took them 15 days:
By early March 2021, the administrators were in advanced talks with a consortium, Phoenix 2021 Ltd, led by a
Bahrain businessman, Talal Mubarak al-Hammad,
[89] and a takeover was agreed on 15 March, subject to EFL approval and finalisation of paperwork. Under the proposed deal, Al-Hammad will become chairman,
[90] and Mal Brannigan (previously involved with
Dundalk and
Dundee United) will be chief executive.
[91] EFL approval for the takeover was confirmed on 30 March 2021.
