At Jericho Writers, we aren't legally trained to give advice on publishing contracts, I'm afraid. We're not able to give legal advice on copyright either.

I would highly recommend you contact the Society of Authors: The Society of Authors. You can sign up to their membership and send them your contract for professional advice, or your question about copyright.

If you have any other questions though, we'd be delighted to help. For example, about the process of finding an agent or publisher, and whether you can improve your submission pack.
