Is an Electronic Signature Legally Valid in Turkey? (2026)

Adira EditorialLegal AI desk5 min read

Yes. In Turkey an electronic signature can be legally valid and can be used to conclude most business contracts. The governing law is the Electronic Signature Law, Law No. 5070, in force since 2004. A central feature of the Turkish system is the secure electronic signature, which the law treats as having the same legal effect as a handwritten signature. So the answer is a clear yes, with the important detail that the strongest standing is reserved for that secure form. This is general information, not legal advice. The rules change and every transaction is different, so confirm the current position before relying on any point below. ## The law that governs e-signatures in Turkey Law No. 5070 defines electronic signatures and sets the conditions for a secure electronic signature, known in Turkish as guvenli elektronik imza. A secure electronic signature is linked only to the signer, created with a means under the signer's sole control, based on a qualified certificate, and lets any later change to the signed data be detected. The law provides that a secure electronic signature has the same legal result as a handwritten signature. The sector is supervised by the national information and communication technologies authority, which oversees the electronic certificate service providers. <!-- [VERIFY] exact article numbers of Law No. 5070 and the current list of licensed electronic certificate service providers before citing them as fixed --> This makes Turkey a certificate-led system. For contracts that matter, parties generally want a secure electronic signature based on a qualified certificate. ## Types of electronic signature recognised Turkish practice distinguishes an ordinary electronic signature from the secure form. - An ordinary electronic signature is any electronic method that identifies the signer and shows approval, such as a typed name, a scanned signature or a click to accept. It can have evidential value, but it does not automatically equal a handwritten signature and its weight depends on the surrounding evidence.

  • A secure electronic signature meets the statutory conditions above and is based on a qualified certificate. The law gives it the same legal effect as a handwritten signature, which is why it is the form used for important contracts. <!-- [VERIFY] the precise statutory conditions for a secure electronic signature under Law No. 5070 before stating them as definitive --> The practical rule is to use a secure electronic signature whenever you need the certainty of a handwritten signature. ## What you usually cannot sign electronically Turkey excludes certain transactions from the equivalence rule, usually because another law requires an official form, a notarised deed or a specific procedure. Even a secure electronic signature does not replace those formalities. Commonly affected are transactions that must be made before a notary or in official form, such as certain real estate dealings and some guarantees or sureties. <!-- [VERIFY] the exact list of transactions excluded from the handwritten-signature equivalence under Turkish law before relying on it --> If a transaction must be made before a notary or in a set official form, treat electronic signing as the first step and confirm what the notary or registry will accept. ## How to make an electronic signature stand up in Turkey Whether a signature carries full weight usually depends on whether it is a secure electronic signature and on the record behind it. 1. Use a secure electronic signature for important contracts. Only the secure form, based on a qualified certificate, is treated as equal to a handwritten signature.
  1. Keep the evidence. Save the audit trail: who signed, when, from where, the version signed and how identity was checked.
  2. Check authority. Confirm the person signing can bind their company and record how you confirmed it.
  3. Agree the method. A clause stating that the parties agree to sign electronically and will accept electronic signatures as valid removes later argument.
  4. Confirm formalities. For transactions that need a notary or official form, check the extra steps before you rely on the electronic version. ## How Turkey compares Turkey's structure is close to the European Union's eIDAS Regulation, where a qualified electronic signature is the form that equals a handwritten signature. The secure electronic signature under Law No. 5070 plays the same role. The United States uses the ESIGN Act and state UETA laws, and India uses the Information Technology Act. In each, ordinary electronic signatures work for most contracts, a stronger certificate-based tier exists for high trust use, and a short list of documents is excluded. Turkey's secure electronic signature is its high trust tier. ## Keeping signing inside the contract workflow An electronic signature is only the last step of a contract. Before a document is ready to sign it has to be drafted, reviewed, negotiated and version controlled, and after signing it has to be tracked for renewals, obligations and key dates. When signing sits in one tool, drafting in another and tracking in a spreadsheet, the signed copy and its terms drift apart. Drafting, reviewing, signing and stamping, then tracking and governing a contract can live in one AI workspace tuned to how your company contracts. Adira is built around that workspace, running on Claude, with e-signing and e-stamping embedded in the flow, per-seat pricing shown up front and a 7-day trial, India-first and built to work across jurisdictions. A single legal-health view, the Command Centre, is on its roadmap. You can read more at adiralaw.com. For one signature the guidance above is enough on its own. The point worth keeping is that a signed contract is easier to rely on when the document, its signature trail and its key dates stay in one place.
