The lawyer
About Klaas Zondervan
I help international heirs, beneficiaries and executors navigate Dutch inheritance law with confidence, and I act on your behalf in the Netherlands.
If you live outside the Netherlands and are facing a Dutch inheritance, the process can feel distant, unclear and stressful.
Different laws, unfamiliar notarial procedures and an executor who does not communicate can make it difficult to understand your rights, especially when you cannot travel to the Netherlands.
My name is Klaas Zondervan. I represent clients in the US, the UK, Canada, Australia and many other countries, focusing on Dutch estates with international elements. Whether you are dealing with a silent executor, assets spread across several jurisdictions, or simply do not know where to begin, I guide you through every step.
For more than a decade I have dedicated my practice to cross-border inheritance matters, because I saw how vulnerable heirs abroad often are. My goal is that international heirs have someone in the Netherlands who truly represents their interests: someone who explains the law clearly, handles the practical tasks they cannot perform from abroad, and makes sure their inheritance is settled properly and fairly.
Focus
A practice focused on international Dutch estates
My work is dedicated to cross-border inheritance cases, where heirs, beneficiaries or executors outside the Netherlands face:
Unfamiliar procedures
Dutch notaries, certificates of inheritance, court filings and deadlines.
Complex rules
Statutory division, forced share, community property, legacies and conditions.
A silent executor
No information, no progress, or decisions that favor one heir over another.
Assets in several countries
Coordination between legal systems, banks and tax authorities.
In some matters this includes complex cases involving paternity, where the first question is who is legally an heir under Dutch law, particularly when recognition happens after death.
I recently helped two U.S.-based heirs resolve a stalled Dutch estate with assets in three countries, without them needing to travel.
Working with me
What you can expect
- A clear explanation of your rights in plain English
- Full representation in the Netherlands: no travel required
- Direct communication with one specialist, not a team of assistants
- A quick assessment of the executor’s behavior
- Remote handling of Dutch paperwork, banks, notaries and tax forms
- Guidance through every step of the probate process
Qualifications
Expertise in Dutch inheritance law
I completed both Specialist Training in Estate Planning and Specialist Training in Estate Liquidation, giving me in-depth knowledge of the Dutch Civil Code, in particular inheritance law (erfrecht) and the rules on probate, executors, heirs’ rights and the settlement of estates.
Dutch courts frequently appoint me as liquidator of complicated or disputed estates. These appointments reflect independent confidence in my ability to manage estates fairly, transparently and in accordance with Dutch law. Through this work I have extensive experience when executors fail to act, heirs live abroad, estates contain assets in several countries, or disputes arise about the administration, distribution or validity of the estate.
Recognition
Professional background
I am registered with the Dutch Association of Legal Advisors (NVRA), where I served on the national board from 2018 to 2021, and I am a NOVEX-certified executor and liquidator.
I am fluent in Dutch and English and was sworn in as a court-authorized English translator at the District Court of The Hague: an important asset when communicating with foreign heirs and reviewing international documents.
In the Netherlands I am known as the inheritance expert on the national TV program De Erfgenaam (“The Heir”), where I help trace missing heirs to unclaimed estates.
