"An author of a copyrighted work can use a pseudonym or pen name. A work is pseudonymous if the author is identified on copies or phonorecords of the work by a fictitious name. Nicknames and other diminutive forms of legal names are not considered fictitious. Copyright does not protect pseudonyms or other names.
If you write under a pseudonym but want to be identified by your legal name in the Copyright Office’s records, give your legal name and your pseudonym on your application for copyright registration. Check “pseudonymous” on the application if the author is identified on copies of the work only under a fictitious name and if the work is not made for hire. Give the pseudonym where indicated.
If you write under a pseudonym and do not want to have your identity revealed in the Copyright Office’s records, give your pseudonym and identify it as such on your application. You can leave blank the space for the name of the author. If an author’s name is given, it will become part of the Office’s online public records, which are accessible by Internet. The information cannot later be removed from the public records. You must identify your citizenship or domicile.
In no case should you omit the name of the copyright claimant. You can use a pseudonym for the claimant name. But be aware that if a copyright is held under a fictitious name, business dealings involving the copyrighted property may raise questions about its ownership. Consult an attorney for legal advice on this matter.
Works distributed under a pseudonym enjoy a term of copyright protection that is the earlier of 95 years from publication of the work or 120 years from its creation. However, if the author’s identity is revealed in the registration records of the Copyright Office, including in any other registrations made before that term has expired, the term then becomes the author’s life plus 70 years.
I hate to hone in on someone else's question, but I am new to this site and new to the world of kindle direct publishing. My question is very similar. If I copyright my book and state that I am using a psuedonym, how do I fill out the author section in kdp so I still receive payment. Do I just write my pseudonym as author or do I need to add a slash and then my real name in order for the check to be made out to me. I considered using my psuedonym under author and my real name under publisher since it seems like they make the checks out to the publisher anyway. Would that work? Any advice on this would be really helpful.
