About us.

Boutique law firm

We are Claudia Koken and Esther van Aalst. We are the boutique law firm COMP. lawyers. Our total focus is on competition, consumer and compliance matters. That is exactly what we have been doing for the past 25 years. 

Imagine: we joined forces. This enables us to provide you and all our international and national clients with the best tailored competition and consumer law advice and strategies.

Our clients entrust us with their – challenging – competition, consumer and compliance cases. We know from experience that these matters are crucial and have a major impact on you, your business and your corporate reputation. 

Your reputation is key to the success of your business. All our clients are companies, some of them are among the world’s largest multinationals, while others are scale-ups working hard to gain Unicorn status.

When you breach competition and consumer law rules, your reputation is affected. Your business could face investigations by competition or consumer law authorities. Your commercial contracts may be invalid. High fines can take up 10% of your consolidated turnover and can lead to potential claims for damages that further discredit your business.

We know the risks. We guide, advise and supervise when it is relevant and matters. Our unique approach puts your reputation and your business success at the heart of our work. That makes us experts in our fields. With over 25 years of experience and our backgrounds working for regulators, for global law firms and as in-house counsel, we have the track record needed to provide you with the best service.

We are committed to providing clear, pragmatic advice and effective business solutions. We simplify for effectiveness. With our personal approach, we take care of your business and – where and if necessary – we cure.
