A significant share of businesses in Turkey operate as sole proprietorships. Small-scale producers, freelancers, boutique shops, e-commerce sellers and service providers all favour this structure. So can a sole proprietorship register a trademark? The answer is yes — but the logic of the process differs from that of capital companies. In this article we look at how trademark registration works for sole proprietors, and what to watch for if you later incorporate.
The Legal Structure of a Sole Proprietorship
Unlike a limited or joint-stock company, a sole proprietorship has no separate legal personality. The business is the owner. Tax liability is registered in the owner's name, and debts and receivables form part of that individual's personal estate.
The direct consequence is this: the trademark, too, is registered in the name of the individual. The application is based not on a trading name like "... Trading Co." but on the owner's own name and national ID number.
How Do You Apply?
For a sole proprietor, the process is identical to that of any individual applicant:
- Clearance search: Checking whether the mark, and variations of it, is available on the register.
- Class decision: Identifying the Nice classes that fit your field of activity. This step is critical because classes cannot be added after filing.
- Preparing the specimen: Choosing a word mark, a figurative mark, or a combination of the two.
- Filing the application: Submitted through TÜRKPATENT's electronic system, using an e-signature or mobile signature.
- Paying the fees: The filing fee is paid; the registration certificate fee is paid separately once the process concludes.
We describe the technical workflow in our EPATS Guide. For class selection, see our Trademark Classes article and our Full List of the 45 Nice Classes.
Advantages of Registering in an Individual's Name
- Independence from the business: Even if you close your sole proprietorship, the mark stays with you. Years later you can carry on using the same mark under a new business.
- Flexibility: If you incorporate, you can transfer the mark to the company, or license it for the company's use. Both options remain open.
- Protection in partnership situations: If you later take on a partner, the mark stays with you and you grant the company a right of use.
- Continuity: Even if your tax registration changes, the mark is unaffected.
Risks to Watch For
- Personal asset risk: A trademark is an item of property. It can become subject to enforcement proceedings over your personal debts.
- Inheritance: On death, the mark passes to the heirs, and if there is more than one heir, joint ownership arises. This can complicate managing the mark. We cover this in our Trademark Assignment and Inheritance article.
- Grant applications: Some support programmes may require the registration to be in the name of the business receiving the grant. See KOSGEB Grants for Trademark Registration.
- Investor perception: In institutional investment processes, the mark is expected to sit within the company's assets.
What If You Later Incorporate?
Moving from a sole proprietorship to a limited or joint-stock company is a very common path in Turkey. As far as the trademark is concerned, you have two options:
Option 1: Transfer the mark to the company
The mark is transferred, along with its registration, to the company and becomes part of the company's assets.
- Advantage: The mark and the business activity sit within the same legal entity, which simplifies investment, sale and grant processes.
- Watch out for: The assignment must be in writing and recorded on the register. Its tax consequences should also be assessed in advance.
Option 2: License the mark to the company
You keep the mark, and the company uses it under license.
- Advantage: The mark stays within your personal estate and is unaffected by the company's possible financial troubles. You can also earn licence income.
- Watch out for: The licence agreement must be in writing and recorded on the register. Its tax dimension should not be overlooked.
We cover the licensing model in detail in our Trademark Licence Agreement article.
The Use Requirement Also Applies to Sole Proprietors
A mark not put to genuine use within a set period from the registration date can become subject to a revocation request. This rule applies regardless of whose name the mark is registered in.
The practical takeaway for sole proprietors is this: keep organised records proving you use your mark. Invoice descriptions that mention the mark's name, packaging and label samples, dated social media posts and advertising invoices form the backbone of this file. For more detail, see our Trademark Use Requirement article.
The Difference Between a Brand Name and a Business Name
There is a common source of confusion among sole proprietors: assuming that the business name on the tax certificate is the same thing as the trademark.
The name on your tax certificate relates to your tax registration and gives you no trademark right. Likewise, registering with the trade registry provides no trademark protection either. The tax office's records and the trademark register are two entirely independent systems; appearing in one creates no right in the other. Only trademark registration creates protection over your products and services. We go into this distinction in our Trade Name, Business Name and Trademark Differences article.
For Sole Proprietors Selling on Marketplaces
A significant share of sole proprietors sell through online marketplaces. For this group, trademark registration is especially critical:
- Brand protection programmes require a registration certificate for enrolment.
- You can only get unauthorised sellers listing your product removed if you hold a registered mark.
- It gives you a basis to act against imitation of your store name.
For scope planning, class 35 should be obtained alongside your product class; we cover this in our Trademark Registration for Trendyol and Hepsiburada article.
In Informal Partnerships, Whose Name Should the Mark Be In?
Sole proprietorships sometimes involve a de facto partnership: two people work together, but the tax registration sits in one person's name only. In that case, whose name should the mark be registered in?
There are two options. The mark can be registered in one person's name alone; this makes management simpler, but if the partnership breaks down, the other party is left with no rights at all. Alternatively, a joint application can be filed, creating joint ownership of the mark.
Joint ownership carries its own cost: dispositions such as assignment, licensing or pledging require the consent of all the co-owners. If the relationship breaks down, both using and managing the mark becomes difficult.
The soundest approach is to put the partnership arrangement in writing from the outset, setting out in the contract who owns the mark and what happens to it if the partners part ways. If incorporation is on the horizon, registering the mark in the name of the company to be formed resolves this problem at the source.
Cost Perspective
The cost of trademark registration does not change depending on whether the applicant is an individual or a company. What determines it is the number of classes: under the official fee schedule the first two classes are charged at the same rate, after which an additional class fee applies.
The practical advice for sole proprietors is to keep the scope realistic. Registering in fields where you have no real activity increases both the cost and the future risk of partial revocation. For current figures, see our Trademark Registration Fees 2026 article.
When Should You Apply?
The answer is the same at every scale: as early as possible. Priority in trademark law is set by the filing date, and sole proprietors very often use their brand names for years without registering them. Throughout that time, the risk that someone else registers the name first exists every single day.
What is more, in such a scenario it is not only the name that is lost: the signage, packaging, domain name, social media identity and customer recognition all have to be rebuilt too. For sole proprietors this loss is proportionally heavier, because the business's recognition is usually tied to a single name and there is no backup brand in the portfolio.
