I published my book in 2013 with one publisher in India. As I was unhappy with the publisher—he had made changes to the book while editing which I was not happy with—the book did not do very well. I have now revised the book and want to publish, self publish. Am I breaking the UK copyright law?
It really depends on what you signed in that original publishing contract.
Did you give them world rights? If so, you could end up in trouble.
As an independent, you should seriously consider joining the Alliance of Independent Authors or The Society of Authors. Both of which will review contracts and let you know where you stand.
