In the United States, as in most countries, it is possible to own a copyright without registering it. Copyright registration is not a prerequisite to copyright protection. Rather, a copyright comes into being when a human being fixes original, creative expression in a tangible medium (or when it is fixed in a tangible medium at a human being’s direction.) Nevertheless, there are important reasons why you should register a copyright in a work you’ve created, particularly if you live in the United States.
Reasons for registering copyrights
If you live in the United States, the most important reason for registering a copyright is that you will not be able to enforce it unless you do. As a condition of filing an infringement claim in court, the United States Copyright Act requires a copyright owner to have applied for registration and received either a certificate of registration or a denial of registration from the U.S. Copyright Office. Registration is not a prerequisite to serving a cease-and-desist letter or a DMCA take-down notice. If you want to enforce your copyright in court, though, then you will need to register it.
This is true, as well, of infringement claims filed in the Copyright Claims Board (sometimes called the “copyright small claims court” or “CCB”). It is not necessary to have received either a registration certificate or denial letter from the Copyright Office before filing a claim with the CCB. It is necessary, however, to have at least applied for registration before filing a claim.
Prompt registration is also important. You may not be able to recover statutory damages and attorney fees in an action for copyright infringement unless you registered the copyright either within three months after first publication or before the infringement began.
Registration gives you the benefit of a legal presumption that the copyright is valid. It also gives rise to a presumption of ownership, and that all of the other facts stated in the certificate (date of creation, etc.) are true.
Registration is not only critical to enforcement; it is also an important defensive strategy. If someone else registers the work and you do not, then they get all of the benefits described above and you do not. As the original creator of a work, you do not want to find yourself in the position of being sued for “infringing” your own work.

Registration workarounds that aren’t
The “poor man’s copyright”
One dangerous myth that has been circulating for years is that simply mailing yourself a copy of your work will be enough to establish your rights in it. This is not true. Anybody can make a copy of someone else’s work and mail it to himself or herself. Even if doing that could establish a person’s rights in a work, it is still going to be necessary to register the copyright in the work in order to enforce it in the U.S. legal system. And you won’t get any of the other benefits of registration, either, unless you do.
Posting to YouTube or another Internet website
Posting a copy of a work to YouTube or another Internet website is a modern-day version of the “poor man’s copyright” myth. The best this will do, however, is provide a date and time of posting. That proves nothing about authorship, and it does not provide any of the benefits of registration.
Notary
Notarization only verifies the validity of a signature; it does not prove anything about authorship.
Having an agent, distributor or licensing agency
Having an agent or a distributor, or listing with ASCAP, for example, does not prove authorship, nor does it provide any of the benefits of registration.
Registries and databases
Some websites offer to list your work in a “registry” or other database, supposedly as a means of protecting your copyright in the work. Some of these websites border on fraud. “Registering” your work with a private company or service will not prove authorship and will not give you any of the other benefits of registration. In the United States, the benefits of registration flow only to those who register the copyrights in their works with the United States Copyright Office.
