I think this business of CM's contracts is not relevant to most of the works, which were recorded under contracts with other companies.

As for obtaining any settlement, as discussed above, even if you can afford the expense and win the case, you will very likely be unable to collect your winnings. 'Phoenix' companies are very often used, so much so that the Government has created legislation which can be used to remove the protection of the limited company, and make Directors personally liable for debts - but this is unlikely to help in this case.
