One possible scenario is this:
As a result of a marriage separation, one of the parties, who is a shareholder in the business, wants to exit the business and retain their shareholding as cash to settle the financial separation. There may be not enough cash in the business to do that without becoming insolvent, so you go into voluntary administration, rearrange the ownership structure of the company, and organise some debt (or find another shareholder) to pay out the cash equity to the departing shareholder.
