Jan-Willem Wiertsema

Jan Willem Wiertsema is the legal cornerstone of Baerz & Co. As a real estate attorney and notary with a sharp analytical mind and many years of experience in complex property and transactional structures, he brings clarity to matters that often seem impenetrable to clients. His approach is pragmatic, solution driven, and surprisingly accessible, exactly what is needed in a field where interests are significant and every detail matters.

With deep knowledge of real estate law, corporate structures and international transaction mechanics, Jan Willem is a trusted guide for investors, entrepreneurs and private clients looking to expand or refine their real estate portfolios. He understands the dynamics of deals, the sensitivities of negotiations and the importance of legal strategies that mitigate risk while opening doors to opportunity. Within Baerz & Co he works closely with our tax and finance professionals, offering clients a fully integrated perspective that aligns seamlessly with their personal and business ambitions.

Jan Willem has a strong sense for nuance. He reads situations quickly, identifies where potential can be unlocked and knows how to maintain momentum when a transaction threatens to stall. What sets him apart is his ability to make both legal and notarial processes understandable without losing any precision. He brings calm to complexity and direction to uncertainty, always remaining firmly focused on the client’s best interest.

Outside the office, Jan Willem is a devoted father of two. Together with his wife he travels to Italy several times a year, where he enjoys the culture, gastronomy and relaxed authenticity of the Italian lifestyle. He also has a deep interest in geopolitical and economic issues, a passion that runs so deep he is currently writing a book on the subject. That broad curiosity shapes his professional work as well, driving him to look beyond the surface and understand the deeper context behind decisions and structures.

Unsurprisingly, transparency and integrity form the foundation of Jan Willem’s moral compass. For him these are not decorative principles, but essential values that guide every interaction. He says what needs to be said, even when a client may prefer not to hear it, always with the aim of protecting their interests and strengthening the outcome.

With his sharp mind, steady presence and human centred approach, Jan Willem is a trusted partner for anyone navigating the often complex world of real estate, legal strategy and notarial decision making.
