Software Escrow Agreements Explained: Turkey Guide 2026

When a company's daily operations depend on proprietary software, the source code sitting on the vendor's server is one of the most underestimated business risks. A software escrow agreement puts a copy of that code in trusted neutral hands — accessible to you if the vendor ever disappears, becomes insolvent, or stops providing support. For foreign-owned businesses in Antalya and across Turkey, getting this right means understanding both international licensing practice and Turkish law.

What Is a Software Escrow Agreement?

A software escrow agreement is a three-party contract between a software vendor (the licensor), the client (the licensee), and a neutral custodian who holds the source code in deposit. The custodian — often a bank, a notary, or a specialist escrow service — releases the code to the client only when a defined trigger event occurs: typically the vendor's insolvency, a material breach of the maintenance agreement, or a prolonged failure to provide support.

The arrangement addresses a fundamental imbalance in software licensing. The vendor retains copyright and control over the source code; the client receives a working application but cannot touch the underlying code. If the vendor folds, the client has a product it can no longer maintain, update, or migrate. Escrow bridges that gap without requiring the vendor to hand over its intellectual property outright.

The Vendor Risk That Makes Escrow Essential

Turkey's software market includes many small and mid-sized development firms that build bespoke systems for enterprises, hospitals, and government bodies. Over time some of these firms have closed, changed ownership, or simply stopped supporting older products. For companies running mission-critical systems — manufacturing ERP, healthcare information platforms, accounting software — losing access to source code can mean days of operational downtime.

The risk is sharper for foreign businesses in Turkey. They often rely on local developers or overseas suppliers with no Turkish entity. If the relationship breaks down, pursuing source code through litigation can take years. If the vendor has already dissolved, even a favourable court judgment may yield nothing practical.

Turkish courts have recognised bank-vault source code deposits as valid escrow arrangements. In a decision by the 11th Civil Chamber of the Court of Cassation (Yargıtay 11. Hukuk Dairesi), the court examined a software licence agreement under which source code CDs were deposited in a bank vault rented by the client, with clearly defined conditions for when the vault could be opened. The court treated this arrangement as legally enforceable and reviewed the trigger conditions in detail.

How Turkish Law Governs Software and Source Code

Software is protected in Turkey as a literary work of science under the Law on Intellectual and Artistic Works (Fikir ve Sanat Eserleri Kanunu, or FSEK). Both source code and compiled code fall within this protection.

Under FSEK, the creator of the work is the author. When a developer is employed, the employer generally holds the right to use the software created in the course of that employment. For software developed under a standalone development contract — common in Turkey — rights must be addressed explicitly in writing. The requirement of written form for any transfer of financial rights is strict; verbal agreements or implied understandings do not suffice.

These rules matter for escrow because the agreement must clearly state whether the custodian receives ownership, a conditional licence, or merely a right of access upon a trigger event. FSEK also provides a compensatory remedy equal to three times the agreed licence fee where copyright-related rights are infringed — a significant deterrent against vendors who wrongfully block access.

What a Sound Escrow Arrangement Looks Like

Turkish courts have recognised both bank vault deposits and detailed "Source Code Delivery and Security Protocols" as valid escrow mechanisms. Based on case law and accepted commercial practice, a solid arrangement should cover:

• Description of deposited materials: all source code versions, build instructions, technical documentation, and third-party library details.
• Defined trigger events: vendor insolvency, failure to maintain the software beyond a set period, material breach of the licence agreement.
• A neutral custodian: a licensed bank, public notary, or professional escrow service. The custodian's obligations must be set out in writing.
• A clear access protocol: who may open the deposit, under what verification, and with what notice. Courts have paid close attention to whether access conditions were agreed in writing.
• Update obligations: the vendor must deposit updated source code whenever a significant new version is released — a one-time deposit that grows stale provides little real protection.
• Confidentiality terms: the client receives access for business continuity only, not to commercialise or redistribute the code.

Getting these clauses right in Turkish — reflected in both the main licence agreement and a separate escrow agreement — is the difference between protection that works and one that collapses in practice.

Frequently Asked Questions

Q: Does Turkish law require a software escrow agreement?

No. Turkish law does not mandate software escrow for commercial transactions. It is optional but strongly advisable, particularly for businesses that depend on bespoke systems or long-term technology relationships.

Q: Can we add an escrow clause to the main licence rather than signing a separate contract?

Yes. Turkish courts have recognised source code delivery obligations embedded in a licence agreement, including as a detailed annex or protocol. A standalone tripartite agreement with a bank or notary is generally more robust, but a well-drafted integrated clause is legally valid.

Q: What if the vendor refuses to deposit the source code as agreed?

The client can seek specific performance through the courts, plus damages. FSEK provides for a remedy of three times the agreed licence fee where copyright rights are infringed. In Antalya and other Turkish commercial centres, intellectual property disputes are handled by specialist commercial courts.

Q: Our vendor has no Turkish entity. Can escrow still work?

Yes. Foreign vendors can deposit source code with a Turkish bank, notary, or international escrow service. The key is ensuring that the governing law and dispute resolution clauses give Turkish courts — or an agreed arbitral body — jurisdiction to enforce the terms.

Q: How often should deposited materials be updated?

At every major version release and at least annually for regularly maintained software.
