One Focus: Precious Metals and Precious Stones Complete Command: Foreign Exchange Legislation
We have written the book on both.

Command is earned by seeing the detail.
The rules governing the movement of foreign currency, precious metals and precious stones do not sit in a single law. They are spread across decrees, communiqués (tebliğ) and circulars (genelge), and they change often. We follow that dispersion and structure our clients' transactions accordingly.
Our Compass: Looking at the Detail Through a Loupe
A jeweller's loupe reveals what the naked eye misses. In foreign exchange (kambiyo) and precious metals legislation, too, the issue usually lies not in the rule itself but in its detail: a deadline, a threshold, an exception. Our work begins in that detail.

At Türkkan Law Firm, we believe that the reflection in the digital world of the principle of "justice for all", which lies at the foundation of law, is "access for all". With this belief, we are committed to making our website a resource that all users, whatever their abilities and needs, can navigate and understand with ease.
Our website aims to meet the Level AA success criteria of the internationally recognised Web Content Accessibility Guidelines (WCAG) 2.2. In the design and technical infrastructure, basic principles such as compatibility with screen readers, keyboard navigation and sufficient colour contrast have been observed.
For us, this is not a destination but an ongoing journey. If you encounter an accessibility problem or have a suggestion that would improve the experience, you can contact us at selam@turkkanlawfirm.com.
Testing and known gaps
Our site is checked automatically each time it is prepared for publication; the heading structure, the naming of links, in-page link targets and keyboard usability are within the scope of this check. The target size and focus visibility criteria introduced in WCAG 2.2 have been measured in the browser. Colour contrast is also assessed separately in the browser by measuring the actual backgrounds of the text.
As of today, these tests show no unresolved gaps.
Points that cannot be measured by script and continue to be assessed manually:
End-to-end testing with screen readers on real devices
The size of touch targets on real devices
