Non-Compete Clause Breached? What Utrecht Employers Need to Know

Non-compete violations in Utrecht — a growing risk in a tight labour market

Utrecht is one of the fastest-growing economic regions in the Netherlands. With its concentration of professional services around the Jaarbeurs area, the tech and startup sector at Utrecht Science Park, and financial institutions along the Catharijnesingel, professionals frequently change employers. That mobility is healthy for the labour market, but it creates risk when departing employees are bound by non-compete or non-solicitation clauses.

A non-compete clause (Article 7:653 of the Dutch Civil Code) restricts a former employee’s ability to join a competitor or approach relationships of the previous employer. The clause is only valid if agreed in writing in a permanent employment contract. Additional justification requirements apply to fixed-term contracts. The District Court of Midden-Nederland in Utrecht regularly assesses in summary proceedings whether a clause was rightfully invoked and whether the employer has sufficiently demonstrated a breach.

Signs that your non-compete clause is being violated

Not every job change constitutes a breach. It becomes problematic when specific behaviours indicate a violation of the contractual terms. Watch for these signals:

• A former employee appearing at a direct competitor in the same region within the restricted period
• Clients unexpectedly switching to the new employer of the departed staff member
• Sensitive business information such as pricing lists, client databases, or bidding strategies surfacing at the competitor
• LinkedIn activity or Chamber of Commerce registrations indicating competing activities within the restriction period
• Reports from your network that the ex-employee is actively approaching your business relationships

Gathering evidence requires care. Unlawfully obtained evidence — for example through hacking email accounts or deploying GPS trackers without legal basis — will be dismissed by the court and may even lead to a counterclaim. The GDPR (AVG) imposes strict requirements on how personal data may be processed during an investigation.

How SAJ Recherche establishes breaches

SAJ Recherche conducts non-compete investigations aimed at collecting objective, lawfully obtained evidence. The investigative methods are tailored to the specific situation and may include:

• OSINT analysis: systematic research of public sources including LinkedIn, Trade Register entries, job boards, and social media
• Surveillance: physical observations to confirm whether the ex-employee is actually working at a competitor, for instance at business premises in the Utrecht region
• Administrative research: analysis of invoice flows, client transfers, and commercial patterns suggesting the use of proprietary business information
• Witness statements: approaching relevant contacts within the professional network

The investigation is carried out within the framework of the Wpbr (Private Security and Investigation Agencies Act). SAJ Recherche holds the required POB licence. The final report contains factual findings supported by source references and is suitable for submission to the District Court of Midden-Nederland or for use in a cease-and-desist procedure.

Practical example from Utrecht

A consultancy firm based on the Maliebaan in Utrecht lost three major client relationships within two months of a senior consultant’s departure. The board suspected the former employee had actively solicited clients in violation of the non-solicitation clause. SAJ Recherche established through OSINT research that the consultant had been in digital communication with the competitor even before his departure. Surveillance confirmed his presence at the competitor’s office within the restriction period. The report was submitted in summary proceedings, after which the court imposed a contact prohibition backed by penalty payments.

Acting quickly strengthens your legal position

The longer you wait to gather evidence, the harder it becomes to prove a breach. Digital traces disappear, client relationships consolidate at the competitor, and the court expects you to act promptly when seeking to enforce a clause. Timely, professional investigation is therefore not optional — it is essential.
