No, copyright protection is automatic once your work is created and fixed in a tangible form. However, registering it offers stronger legal protections and provides a public record of ownership.
The registration process can take anywhere from a few weeks to several months, depending on the jurisdiction and workload of the copyright office.
Copyright protection lasts for the life of the author plus 70 years. For works created by an organization or corporation, it typically lasts 95 years from the date of publication or 120 years from the date of creation, whichever is shorter.
