What is the best thing to do if I’m unsure whether my (partially) AI-generated work is protected by copyright?

If, after reviewing the legal framework, you still have serious doubts, BumaStemra advises you not to register the work in question. You may also consult a legal expert in the field of copyright, but just like BumaStemra, they cannot provide a definitive answer. After all, there are currently no European guidelines regarding AI and authorship.
