A pen name doesn’t have to be completely unique, but it does need to work. Before you put it on a cover, find out who else is already using it — because the biggest problem may not be legal at all. It may simply be making sure readers can find you.

You finally find it. The pen name that sounds right, looks good on a cover and fits the kind of books you want to write.
So you do what any sensible author does. You Google it.
And there they are. Another writer. A musician. A consultant in Melbourne. Someone with 40,000 Instagram followers. Perhaps, inconveniently, another novelist writing in exactly your genre. Now what?
The first thing to understand is that finding another person with the same name does not automatically mean you cannot use it.The more useful question is: Do you really want to?
Because when authors run into pen-name trouble, the practical problem is often less about the mere existence of another human with that name and more about reader confusion, discoverability, branding and, in some circumstances, trade mark or consumer-law issues.
Let’s sort out what actually matters.
General information only: This article is intended as practical publishing information, not legal advice. Trade mark, business-name and other legal issues depend on the facts and jurisdiction. If you are dealing with an actual dispute or existing trade mark, speak with an Australian intellectual property professional.
A Pen Name Is Not the Same Thing as a Trade Mark
A few different concepts tend to get bundled together here. They shouldn’t.
Your legal name: This is your actual legal identity.
Your pen name: A pen name or pseudonym is the name you choose to publish under.
Publishing platforms recognise this perfectly ordinary practice. Amazon KDP, for example, expressly permits authors to publish using a pen name while requiring the author’s legal identity in the account information used for verification, payments and tax purposes.
Your business name: If you actually conduct a business under a name other than your own, Australian business-name registration may come into play.
Business names are registered nationally through ASIC. Importantly, registering a business name allows you to trade under that name but does not give you exclusive intellectual-property rights to it. ASIC specifically distinguishes business-name registration from trade mark protection.
Your trade mark: This is different again. A registered trade mark can provide exclusive rights in relation to the particular goods or services covered by the registration. That qualification matters.
You do not simply register a name and thereby own those words for every conceivable purpose. Trade marks operate in relation to nominated goods and services, which are organised into 45 classes.
For authors and publishers, the relevant classifications can vary depending on exactly what is being protected. For example, IP Australia identifies printed publications in Class 16, downloadable electronic publications in Class 9 and certain online publication services in Class 41.
So if an actual trade mark issue arises, this is one area where guessing based on a class number from a blog is not a sensible strategy.
What If the Other Person Isn’t an Author?
Suppose you want to write thrillers as Daniel Foster.
You search the name and discover a Daniel Foster who runs an air-conditioning business in Perth. That alone would not make me abandon the name. From a practical author-branding perspective, I would look at things such as:
- how prominent the other person is online
- whether they dominate search results
- whether their work overlaps with yours
- whether readers could plausibly confuse the two identities
- whether relevant trade marks already exist
Two people can have the same name without automatically creating a commercial conflict.
What you want to avoid is creating a publishing identity that could mislead people or become confused with an established brand.
Australian Consumer Law prohibits misleading or deceptive conduct in trade or commerce, so deliberately presenting yourself in a way that suggests an association with somebody else is a very different proposition from simply sharing a name.
Common sense goes quite a long way here.
A suburban accountant and a fantasy novelist who happen to share a name? Probably manageable.
Two romance writers selling books under the same name on the same platforms? Now I’m paying attention.
What If There Is Already Another Author?
This is where I become much less enthusiastic about keeping the name. Not necessarily because the other author can legally stop you, but because you are volunteering for a discoverability problem.
Imagine your pen name is Claire Montague.
You publish your first novel. A reader finishes it, likes it and searches: Claire Montague books. What do they find?
If the first page is already occupied by another Claire Montague with twelve novels, an established website, Goodreads listings, retailer pages, interviews and years of search history behind her, you have made your own marketing job harder before you have even started.
Amazon itself recognises this problem. Its current metadata guidance tells publishers that while pen names are permitted, if an author name is similar to that of a popular author, they should consider using a pen name, middle name or initial to help customers make good buying decisions.
That is worth paying attention to.
You want your author name to do one fairly basic job: Help readers find you.If it makes that harder, it is not doing its job particularly well.
The Closer the Other Author Is to You, the Bigger the Problem
I would look at four things.
1. Same name?Obviously.
2. Same genre?Two authors named Alex King are less likely to be confused if one writes academic history and the other writes paranormal romance. If both write Australian crime fiction, the overlap matters more.
3. Same readers? Genre is only part of it. Are you likely to appear in the same searches, recommendations, retailer categories and online conversations?
4. How established are they? An author who published one book fifteen years ago and has virtually no online presence presents a very different practical problem from an active author with a substantial catalogue.
This is why there isn’t a useful rule that says: Someone else has the name = you can’t use it.
You need context.
What If It’s the Name of a Famous Person?
I would choose something else. Not because every famous person’s name is automatically unavailable, but because you are creating unnecessary problems for yourself.
Call yourself Chris Hemsworth and try building an author platform. Even setting legal questions aside, guess whose search results are going to win.
You are also moving closer to the possibility that people could think your books, advertising or online presence are somehow associated with the better-known person.
If you deliberately build on that confusion, you are no longer dealing with an innocent shared-name situation. Australian law contains protections against misleading or deceptive commercial conduct, and registered trade marks may introduce further issues.
There are plenty of names available.
Pick another one.
What About Trade Marks?
This is where authors sometimes either panic unnecessarily or ignore something they should investigate.
Neither is helpful.
IP Australia maintains the Australian Trade Mark Search database, which contains registered and pending trade marks. You can search by word, phrase, owner, image and goods or services. Its simpler TM Checker tool can also help identify potentially similar existing marks.
A trade mark does not give its owner possession of a word in every context. Protection relates to the goods and services for which the trade mark is registered, and similarity between the goods and services can affect whether similar marks are likely to cause confusion.
That is why I would not tell an author: “Search Class 16. If nothing appears, you’re safe.”That is too simplistic. Search the name itself and investigate anything that appears relevant.
If you encounter a similar registered trade mark covering books, publishing, entertainment or closely related activities — particularly one belonging to another author or publisher — get professional advice before building your brand around the name.
Spending a little money on advice at that stage can be considerably cheaper than redesigning covers and rebuilding an author identity later.
The Bigger Issue for Most Authors: Discoverability
This is the part I think authors underestimate.
A pen name is not simply a creative choice. It becomes an address. Readers use it to find:
- your books
- your website
- retailer listings
- interviews
- reviews
- social accounts
- future releases
Over time, you invest a surprising amount into that name. Cover designers use it. Books are printed with it. Metadata is distributed under it. Domains are registered. Email addresses are created. Readers remember it. Perhaps you spend money advertising it.
Changing your mind after book four is considerably more annoying than changing your mind before book one.
So when evaluating a pen name, I would worry less about whether it sounds wonderfully literary and more about this: Can readers find me easily and be reasonably confident they’ve found the right person?
That is a much better test.
Grif’s Pen Name Check
Before committing to a pen name, I would run through this.
1. Search the exact name:Put it into a search engine in quotation marks. Then try it with:
- author
- writer
- books
- novelist
- your genre
- Australia
Look beyond the first result. You are trying to discover what identity already exists around the name.
2. Search the major book retailers:Search Amazon and any other retailers important to your market. Don’t just check whether the name exists. Look at who owns the search results.Is there another active author? What do they write? How many books do they have? Would a reader reasonably confuse their work with yours?
3. Search social platforms:You do not necessarily need every social-media platform. You do need to know what already exists. Check the platforms you are realistically likely to use and see whether the name or sensible variations are available.
4. Check the domain:Look at the obvious domain possibilities. If the cleanest version of the name is already being actively used by another author, that is useful information. An unavailable domain does not automatically rule out a pen name. It simply becomes another item on the evidence pile.
5. Search Australian trade marks:Use IP Australia’s Australian Trade Mark Search and investigate similar names, not merely exact matches. IP Australia recommends checking existing trade marks before applying for one yourself. It provides both its full search database and TM Checker.
6. Check business-name availability if relevant:If you intend to operate a business under the name, check ASIC as well. Remember that business-name registration and trade mark protection are different things. Registering the business name does not give you exclusive rights to the name as a brand.
7. Think internationally:Self-publishing is rarely confined neatly to Australia. If the United States, United Kingdom or another country will be important to your publishing plans, search there too. IP Australia specifically recommends searching relevant overseas trade mark databases when you intend to take a trade mark into another country.
You do not need to spend three weeks investigating every human who has ever shared the name. You are looking forobvious conflicts before you invest in the brand.
What If You’ve Already Published?
First, don’t panic. Finding another person with the same name doesn’t automatically mean you need to rebrand.
Look at the actual problem.
If there is very little overlap, you may decide to continue. Perhaps the other person works in an unrelated industry or has virtually no presence in the publishing market.
Keep an eye on things and make your own author branding clear.
If another author is creating confusion,consider whether a modest change will solve it. A middle initial can make a surprisingly large difference. For example: Sophie Martinmay become: Sophie J. Martin
You preserve much of the existing identity while giving readers a clearer way to distinguish you.
Amazon’s own metadata guidance suggests a middle name or initial where an author name is similar to that of a popular author.
If the conflict is substantial,sometimes changing early is the cheaper decision.
If you are one book into a planned twelve-book series and have discovered an established author writing in your genre under exactly the same name, ask yourself whether you really want to spend the next decade dealing with that.
Sunk cost is still sunk cost.
If a trade mark owner contacts you,stop trying to solve it through Facebook groups and internet comments. Get proper advice. The details matter.
How Unique Does a Pen Name Need to Be?
Not perfectly unique. That is usually unrealistic. You are not trying to find a combination of letters never before uttered by another human being. You are looking for practical distinction.
A good pen name should ideally:
- be easy to spell
- be easy to remember
- suit the work reasonably well
- be distinguishable from authors targeting similar readers
- produce manageable search results
- give you workable domain and online-branding options
- avoid obvious trade mark problems
If it does that, you’re in good shape.
Choose the Name for the Job It Has to Do
Authors can spend an extraordinary amount of time finding a pen name that feels right.
I understand why. It is going on the cover. But a pen name is not there merely to decorate the top of the book. It has a job. It helps readers identify you, search for you, remember you and find the next book.
So before you order the bookmarks, register six social accounts, put the name on 2,000 printed copies, and spend an hour checking what already exists.
If another accountant in Adelaide has the name, you may decide it doesn’t matter.
If another successful thriller writer does, I’d keep looking.
Because the best pen name is not necessarily the cleverest one.
It’s the one you can actually build on.
