7 Legal Mistakes Startups Make When Incorporating

✍ Av. Mehmet Koru📅 March 2026⏱ 7 min read

A successful product or business idea can run into serious problems due to a poorly structured legal framework. The vast majority of legal issues that arise during investment rounds, partnership disputes or growth stages originate from mistakes made at the incorporation stage.

1. Not Having a Shareholders Agreement

Many startup teams set off with verbal agreements and no written shareholders agreement. When share percentages, vesting schedules, exit conditions and decision-making mechanisms are not clearly defined, serious disputes become inevitable down the line.

2. Choosing the Wrong Corporate Structure

Limited liability company or joint stock company? This choice makes a significant difference for tax advantages, investor structure and future transactions. While a joint stock company is generally more appropriate for startups planning to raise investment, every situation requires individual assessment.

3. Not Having a Vesting Mechanism

If a co-founder can retain their shares even after leaving, this creates a serious problem for both the remaining team and investors. Time-based or performance-based vesting schedules should be structured from the outset.

4. Not Assigning IP Rights to the Company

Failing to assign software, trade marks and other intellectual property developed by founders or employees to the company creates a major obstacle in investment negotiations. This deficiency almost always surfaces during due diligence.

5. Signing Investor Agreements Without Careful Review

Anti-dilution, liquidation preference and drag-along provisions in term sheets and investment agreements can significantly affect founders' rights. Signing these documents without legal advice can have serious consequences.

6. Inadequate Employment Agreements

Employment contracts that do not contain confidentiality obligations, non-compete clauses and IP assignment provisions leave the company exposed. These provisions are critical, particularly for technical team members.

7. Ignoring KVKK Obligations

Every startup that collects user data carries various obligations under Turkey's Personal Data Protection Law (KVKK). Privacy policies, cookie notices and data processing agreements must be structured from the outset. Corrections made later are both costly and reputationally risky.

Conclusion: Investing in legal infrastructure from the beginning significantly reduces costs and risks further down the line. Early-stage legal advisory is not a cost — it is a strategic investment.
