The automatic legal right of a creator to control copying, distribution, and adaptation of an original work, lasting for decades after it's made.
Copyright is automatic. The moment you write, design, photograph, or code something original, you own the copyright — no registration required. It gives you the exclusive right to reproduce, distribute, adapt, and display the work, and in the US it lasts the creator’s life plus 70 years.
For sellers, this is your default position of strength. Unless your contract assigns copyright to the client or the work qualifies as work-for-hire, you keep it — even after you’ve delivered and been paid. That means you can license the same asset again or reuse elements, within reason.
For buyers, paying an invoice does not automatically move copyright to you. If you need to own the logo, the code, or the photos outright, the contract must say so explicitly. Otherwise you’ve bought a license to use it, not the copyright itself.
Registration isn’t required to own copyright, but in the US it’s required before you can sue for infringement and enables bigger damages — worth it for high-value work. For anything you’d fight over, confirm the details with an IP attorney and pin ownership down in the freelance contract up front.
