How they connect
Administration often comes first. If the rescue fails or the business cannot be sold, the administration converts into liquidation. That sequence is common: a company enters administration, the viable parts are sold (sometimes back to the old directors, which is how phoenix activity can arise lawfully), and the shell is liquidated.
What creditors should do
In administration, keep supplying only on new terms agreed with the administrator; pre-administration debts sit inside the process. In liquidation, register your claim promptly and respond to proof-of-debt requests. In both, the order in which creditors are paid is fixed: see who gets paid first in insolvency.
