Have you had a creditors meeting? If not, and you don't want to go ahead then just tell the company you don't want to go any further.

The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

As long as the meeting hasn't taken place you can cancel. However, whether you are liable to pay for work done thus far will depend upon the agreement you have with the firm you are using. Most will not charge -- but some do!
My opinions are merely that .. opinions based on experience. Always seek professional advice.

If you have just signed the initial paperwork to proceed then yes you are not yet committed. However if your creditors meeting has taken place and you have signed your chairmans report then unfortunately you are committed.
