Understand Copyright Registration in Spain
Unlike some countries, Spain does not issue a "certificate of authorship" — SGAE membership does not serve as a copyright registration certificate.
Creators are advised to use digital timestamping services (such as blockchain-based registration services) to establish independent proof of creation date before registering with SGAE. This creates a time-stamped, immutable record of your work's existence.
SGAE membership is what allows you to collect royalties — but proving copyright ownership requires a separate step.
Without an independent timestamp, proving when you created a work can be difficult if a dispute arises. SGAE registration alone is not considered legal proof of creation date under Spanish law.
Assuming SGAE membership constitutes copyright registration. It does not — it allows you to collect royalties. Protect your copyright separately with a digital timestamping service first.
