Once dissolved, a company cannot be sued or pay debts. Any assets it still had pass to the Crown. Companies are sometimes dissolved deliberately to escape creditors.
A creditor can apply to restore a dissolved company to the register — usually within six years — in order to pursue a debt. It is worth it only for larger amounts, as there are costs involved.
Example
A client's company shows as "Dissolved" on Companies House two months after the invoice was due.
