Moving to Spain

Hi, I need some help ☺️... there's so many different things I've read about what's needed to move to Spain, my head's spinning. Do I need anything to be Apostille? Because of covid we can only move over on November 6th, so hence the panic!
If anyone could give me ANY information I would be really grateful ☺️
Thanks for taking the time to read this!
