If you want to earn a doctorate while working, sooner or later you will come across offers from abroad. Many of them are legitimate programmes with real research and real supervision. In between, though, there are providers who sell a doctoral degree without any study behind it. There is a word for them: diploma mill.
The problem is that a diploma mill looks just like a legitimate programme at first glance. A professional website, international partners, graduates with photos. Here I show you the warning signs that reveal the difference, and how to check an offer yourself before you transfer any money.
A disclosure before I continue
I support people on their way into doctoral programmes abroad, including at ULSIT in Sofia, and I am doing my own doctorate there. So I have an interest in this topic, and that is exactly why I do not name any providers in this article, neither positively nor negatively. What you get are the criteria. You can apply them to any offer, including mine.
What a diploma mill is and what it is not
A diploma mill sells a degree without you completing a real programme of study, or it awards a degree it is not entitled to award. Often both apply.
A diploma mill is not:
- a university simply because it is abroad,
- a programme simply because it is designed for working professionals and supervised online,
- an offer simply because it charges fees. In many countries, state universities also charge tuition for doctoral programmes.
So the line is not drawn by country, format or price. It is drawn by whether there is an achievement behind the degree that an entitled university examines.
What the law says about diploma mills
In Germany, the federal states decide which foreign degrees you may use. Their laws are based on a joint resolution of the Standing Conference of Education Ministers (KMK) from the year 2000. It contains a sentence that leaves nothing open: degrees obtained by buying a title must not be used.
The Central Office for Foreign Education spells out the requirements for a foreign degree in more detail. The degree must have been properly awarded, the university must be state-recognised in its country or accredited under the procedures that apply there, and the degree must have been earned through a programme of study that was actually completed and concluded with an examination. A foreign degree cannot be converted into a German one.
Using a degree without authorisation is a criminal offence under Section 132a of the German Criminal Code, punishable by up to one year in prison or a fine. In other words: with a diploma mill you do not only lose the money. You get a degree you are not allowed to use, and a risk if you use it anyway.
The warning signs of a diploma mill
None of these signs proves a diploma mill on its own. But if several of them come together, do not sign.
1. The degree comes without your own research
"Doctorate based on your professional experience", "no dissertation required", "recognition of your life's work". A doctorate is proof that you can carry out independent research. If it does not end with a dissertation that you wrote and defended, it is not a doctorate.
2. Duration and outcome are guaranteed
"Doctor in twelve months" or "success guaranteed". No legitimate programme can promise that your research will succeed within a fixed time and pass the examination. The duration depends on you, the topic and the supervision. How long a doctorate realistically takes alongside a job is covered in part-time PhD: the duration.
3. Nobody supervises you by name
Legitimate programmes tell you before enrolment who can supervise your work, with name, field and their own publications. If you only hear about "our professors" when you ask, or supervision is assigned only after payment, the most important part is missing.
4. The institution is not recognised as a university in its own country
Some providers use names that are confusingly similar to well-known universities, or have nothing but a postal address at their stated location. What matters is whether the institution is state-recognised or accredited in its home country. How to check that is explained below.
5. Accredited by an agency nobody has heard of
Accreditation is only worth as much as the body that grants it. Diploma mills often work with their own "accreditation agencies" that have impressive names and accredit no one else. What counts is whether the home country recognises the agency, not the seal on the website.
6. There is a package price including the certificate
"Complete package with certificate, apostille and doctoral hat." In a real programme you pay tuition, and you receive the certificate once you have passed the examinations. If the certificate is part of the purchase price, you are buying a piece of paper, not a degree. The same applies to an honorary doctorate in exchange for a donation: under the KMK principles, you may only use a foreign honorary degree if the awarding body is entitled to award it under the law of its country.
7. You are promised that you may use "Dr." in Germany
How you may use a foreign degree is not decided by the provider but by the competent authority of your federal state. A provider who promises you the form with binding effect is promising something it does not decide. What applies and whom to ask is covered in detail in doctorate abroad: what to clarify about using the title first.
8. You are pushed to decide quickly
"Only two places left", "special price until Friday". A doctoral programme is a decision for several years. A legitimate provider gives you the time to read the doctoral regulations and gather information.
Legitimate or diploma mill: the comparison
| Check | Legitimate programme | Warning sign |
|---|---|---|
| Achievement | own research, dissertation, defence | degree based on professional experience |
| Duration | realistic, depends on your work | fixed deadline with guarantee |
| Supervision | named supervisors before enrolment | "our professors", assigned after payment |
| Status | state-recognised or accredited in its home country | name like a well-known university, postal address only |
| Payment | tuition for the programme | package price including certificate |
| Using the degree | refers you to the competent authority | promise that you may use "Dr." |
How to check in four steps whether a diploma mill is behind it
1. Look up the institution's status in anabin. The KMK database anabin shows a status for foreign institutions. According to the portal's explanation, H+ means the institution counts as a state or state-recognised university in its home country. H+/- means that further criteria apply to degrees from that country. The database is not complete. If an institution is missing, that alone is not a verdict, but it is a reason for step 2.
2. Ask the national information centre of the home country. Every country in the European recognition network has a centre that provides information on recognised universities. You can find it through the ENIC-NARIC network. Ask whether the institution is recognised as a university in that country and whether it may award doctoral degrees.
3. Request the doctoral regulations. A legitimate programme has written doctoral regulations: admission, supervision, scope of the dissertation, examination, defence. Read them before you sign. If they do not exist, or you only receive them after payment, that is your answer.
4. Ask your federal state about using the degree. Write to the competent authority of your federal state with the country, the name of the university and the exact original name of the degree. The answer is binding and costs you nothing but a few weeks of patience.
Five questions for any provider
Who will supervise my work, with name and field? Where can I read the doctoral regulations? Which dissertations have already been published in this programme, and where can I see them? What is the exact original name of the degree? Which body in your home country can confirm that you may award doctoral degrees? A legitimate provider answers all five without hesitation. A diploma mill dodges by the third question at the latest.
What separates a legitimate doctorate abroad from a diploma mill
A legitimate programme asks the same of you as a doctorate in Germany: a research question, supervision, a dissertation and an examination. It differs in the framework, not in the standard, for example through fixed attendance phases, structured supervision or admission that gives more weight to professional experience. I compare the different forms in DBA or PhD and external doctorate, and what they cost in doctorate costs.
This article describes the legal situation in Germany. Austria and Switzerland have their own rules. Steps 1 to 3 apply there in the same way, for step 4 you ask the authority responsible there.
Conclusion: spot the diploma mill before you pay
- A doctoral degree without your own research, supervision and examination is not a doctorate but a bought piece of paper, and you may not use a degree like that.
- If several warning signs come together, do not sign.
- Check the institution's status in anabin and with the information centre of its home country.
- Read the doctoral regulations before you pay.
- Clarify the use of the degree in writing with your federal state, not with the provider.

Frequently asked questions
Is it illegal to buy a doctorate?
A genuine doctoral degree cannot be bought. Whatever is handed out for money without real study, you may not use in Germany: under the KMK principles, degrees obtained by buying a title must not be used. Using a degree without authorisation is a criminal offence under Section 132a of the German Criminal Code, punishable by up to one year in prison or a fine.
How do I know whether a foreign university is legitimate?
A first indicator is the institution's status in anabin, the KMK database. H+ means it is recognised as a higher education institution in its home country. If it is not listed, ask the national information centre of that country, which you can find through the ENIC-NARIC network. A legitimate programme also has doctoral regulations that you can read before you enrol.
Is a part-time doctorate abroad automatically a diploma mill?
No. Many universities abroad offer doctoral programmes designed for working professionals, with real supervision, independent research and a defence of the dissertation. The format is not a warning sign. It becomes one when research, supervision or examination are missing, or when the outcome is promised in advance.
May I use an honorary doctorate I paid for?
Honorary degrees are awarded for merit, not for study. Under the KMK principles, a foreign honorary degree may only be used if the awarding body is entitled to award it under the law of its country. An honorary doctorate in exchange for a donation or fee from an institution without that right is excluded.
Who tells me with certainty whether I may use the degree?
The competent authority of your federal state, usually the ministry of science. Neither the awarding institution nor an agency or advisor can promise you this with binding effect. Ask in writing before you enrol.
