How can I trust that the proofreader and designer of a book will not plagiarize our work?

Question

My friend and I are writing a book in English in the Electrical Engineering field. At this stage, we need someone to proofread our texts and also to design the layout of the book, so we will need to entrust them with our manuscript. I was wondering, how can we trust that the proofreader and designer of the book will not plagiarize our work?

Answer 1

You can and should have them sign an NDA (Non-Disclosure Agreement), essentially saying that what they are reading is confidential and cannot be shared. Please let me know if you need additional assistance.
