1. About Due-Diligence-Prüfung Law in Winterthur, Schweiz

In Winterthur, Due-Diligence-Prüfung is not governed by a single standalone statute. It is a practice anchored in Swiss federal law and contract law, applied during mergers, acquisitions, financing rounds and reorganizations. The process encompasses legal, financial, tax, and regulatory assessments to identify risks and liabilities before closing a deal.

Practitioners in Winterthur and the Canton of Zürich rely on general Swiss law for due diligence, including fiduciary duties of company directors and broader corporate governance standards. Data privacy requirements under the Federal Act on Data Protection (FADP) shape how information is collected and shared during due diligence. Anti-money laundering controls under the Geldwäscherei-Gesetz (GwG) influence the identification and verification steps in targeted transactions.

Common practice in Winterthur involves coordinating with Swiss-licensed lawyers, auditors and tax advisors to draft a comprehensive due-diligence report and to negotiate protections in the Share Purchase Agreement (SPA). Local courts and regulators interpret and apply these standards when disputes arise around representations, warranties and liability allocations. The evolving regulatory environment in Switzerland continues to push for more robust risk disclosure and data protection.

3. Local Laws Overview

The Swiss framework for due-diligence-prüfung in Winterthur relies on several core statutes and regulatory regimes. Key areas include fiduciary duties of corporate bodies, data protection, and anti-money laundering controls, all of which shape due diligence practices in practice.

Swiss Code of Obligations (OR) - fiduciary duties and corporate governance: The OR sets the standard of care and loyalty expected from directors and management in Swiss companies. In a due-diligence context, auditors and counsel assess whether the target’s governance, contracts and disclosures meet these duties prior to closing. This framework underpins warranties, representations and post-transaction liability allocations.

Federal Act on Data Protection (FADP) - data privacy and processing: FADP governs how personal data is collected, stored, used and transferred during due diligence. The 2020 reform, effective 1 September 2023, strengthens data-protection rights and imposes higher accountability on data processors and controllers in Swiss deals. This affects data room procedures and cross-border information sharing.

Geldwäscherei-Gesetz (GwG) - anti-money laundering and customer due diligence: GwG requires identifying counterparties, beneficial owners and sources of funds in many transactions. In practice, buyers and sellers perform risk-based due-diligence checks to meet GwG obligations, with enhanced scrutiny for politically exposed persons or high-risk jurisdictions. The GwG and its implementing ordinances continue to influence deal structuring and closing conditions.

4. Frequently Asked Questions

What is the purpose of due-diligence-prüfung in Swiss M&A?

Due diligence identifies risks and liabilities before a deal closes. It informs price, representations and warranties, and protective covenants in the SPA. It helps buyers make informed decisions and helps sellers anticipate post-closing claims.

How do I start a due-diligence process in Winterthur?

Begin by engaging a Swiss-licensed attorney and a qualified auditor. Define the deal scope, assemble a data room, and sign a non-disclosure agreement before sharing sensitive information. Establish a timeline and assign responsibilities to core specialists.

What documents are typically reviewed in a Swiss due-diligence?

Typical reviews cover financial statements, tax compliance, contractual obligations, employee matters, IP, real estate, litigation, and regulatory licenses. Data privacy and AML compliance are integrated into the process from the start. The exact scope depends on the target sector and deal type.

Costs vary by deal complexity and buy-side requirements. A basic financial and legal due diligence for a small to mid-size target in Winterthur might range from CHF 20,000 to CHF 100,000, plus advisory fees. Comprehensive reviews with specialized reports cost more.

Do I need a lawyer for due-diligence in Zurich?

How long does a typical Swiss due-diligence take?

For a mid-size target, a thorough due-diligence process generally takes 4 to 8 weeks, depending on data availability and complexity. Complex cross-border deals can extend to 10 weeks or more. Timelines should be aligned with the closing schedule.

Financial due diligence assesses financial statements, cash flow, debt and revenue projections. Legal due diligence reviews contracts, governance, compliance and regulatory exposure. Both are essential for a complete risk picture.

Can due-diligence reveal hidden liabilities in a target company?

Yes. A well-conducted review may uncover undisclosed liabilities, such as contingent liabilities, ongoing litigations, or tax disputes. This informs indemnities, warranties, and post-closing obligations in the SPA.

Key steps include negotiating updated warranties and indemnities, adjusting the SPA terms, and deciding on closing conditions. If issues are unresolved, parties may renegotiate or walk away from the deal.

How does Swiss AMLA and GwG affect due-diligence procedures?
