Türkkan Law Firm is a law firm founded in Istanbul in 2017 by Attorney at Law M. Abdullah Türkkan. The firm works in foreign exchange legislation and capital movements covering transactions in precious metals (gold, silver, platinum, palladium), precious stones (diamond, brilliant, ruby, sapphire, emerald, topaz, peridot, pearl) and foreign currency.
Our founder is the author of two books on the legal framework of this field: Kambiyo Mevzuatı Rehberi: Yasal Düzenlemeler ve Uygulama [Guide to Foreign Exchange Legislation: Rules and Practice], written with R. Bülent Demirbağ, and Kıymetli Maden ve Kıymetli Taş Ticaretinden Kaynaklanan Uyuşmazlıkların Tahkim Yoluyla Çözümü [Arbitration of Disputes Arising from Trade in Precious Metals and Precious Stones] (Vedat Kitapçılık, 2026). He is currently working with Osman Dereli, former President of MASAK (the Financial Crimes Investigation Board), on a book to be published in the first quarter of 2027.
The firm works at every link of the precious metals and precious stones supply chain: from metal mining companies, the first link in the chain, to refineries and workshops; from the sector's wholesalers and retailers to intermediary institutions and authorised institutions; from jewellers to importers and exporters. It provides training to the sector's chambers and associations. Its practice areas are foreign exchange legislation, foreign trade and customs regimes, MASAK (AML/CFT) compliance, corporate and commercial law, and dispute resolution and arbitration. The same client's other legal matters are also handled within the firm.
We work in Turkish, English, German and Russian.
Chapters of Our Story
For us, law is not merely a profession in which rules are applied, but a craft in which every detail is worked with care. This firm took its present shape by choosing to go deep in a single field rather than be a workshop that takes on everything.
Less the founding of a law firm than the story of a craft that found its focus.
01
Roots: Struggle and the Foundations of the Craft
Every master has an apprenticeship. For our founder, Attorney at Law M. Abdullah Türkkan, it was a search that began in İskenderun and reached as far as Kyrgyzstan. That journey taught him, alongside the theory of law, the realities of life, patience, determination and the value of hard work.
02
Turning Point: Narrowing the Focus
After law school, he began working as an attorney at BOTAŞ (Boru Hatları ile Petrol Taşıma A.Ş., Petroleum Pipeline Corporation), and until 2017 worked on the Trans-Anatolian Natural Gas Pipeline Project (TANAP). Seeing the legal workings of a cross-border energy project at close range laid the first foundation of the perspective that would later become a focus on foreign exchange and foreign trade.
Our office, established in Istanbul in 2017, sharpened its focus during the global pandemic in 2020. It was in this period that our boutique, niche approach took shape — concentrating all our energy on a single field rather than being a workshop that “takes on everything”.
The master's programme begun in 2023 was the second turning point, reshaping practical experience with the strength of scholarship.
03
Moment of Clarity: The Risk Becomes Visible
Academic and sector research made visible the complex foreign exchange legislation (kambiyo mevzuatı) risks at the heart of the Grand Bazaar (Kapalıçarşı) ecosystem and of foreign trade. This is how our focus became clear: to make a scattered body of legislation readable for those who have to live with it every day.
04
Our Philosophy: Working by Measure
Gold is measured by its fineness, a diamond by its cut. In this sector, legal work too must be measurable: which provision, which time limit, which authority. Türkkan Law Firm continues to work with the mindset of a founder who reads the past.
How Do We Work?
“We exist to teach what is not known, to recall what has been forgotten and to show what is not seen.”
At Türkkan Law Firm, no client is merely a file. There are five principles to how we work, and all five come from the same place — taking the measure of the matter.
01
First, we measure.
A person who comes to an assay office (ayar evi) does not want to be persuaded; they want to know what the piece in their hand is. So we first establish what the matter is, and then write what is to be done. When the order is reversed, the solution does not fit the problem.
02
Every answer comes with its basis.
Everything we say has a source, a date and an article; we put them all beside the answer — so that you can check them. An answer without its source shown is not an answer but a guess.
03
The cheapest case is the one that is never opened.
In this field, legislation changes several times a year: a communiqué (tebliğ), a circular (genelge), a board decision. We follow the change and give warning while the transaction is being structured. A defence written after a penalty arrives is always more expensive than arrangements made before it does.
04
We explain.
It is not we who make the decision; it is you. A decision cannot be made without understanding what an option gains and what it costs; that is why explaining how the matter works is part of the work itself. It is also why we write in the magazine, in books and on this site.
05
We come to the table prepared.
In negotiation, in court and in arbitration. Preparation comes before the contest: what is said at the table often does not determine the outcome; the work done beforehand does.
Our Team
The People Who Put the Philosophy into Practice
Our team, each member sharing the same calm and transparent working culture. We work in Turkish, English, German and Russian.
