Expertise

Lambertus is a corporate law ‘all-rounder’ for all legal forms and advisory matters, with over 35 years of professional experience. He has advised listed companies and family businesses on conversions, carve-outs, and intra-group restructurings, and has conducted settlement and insolvency proceedings on their behalf.

Thanks to his experience with owner-managed and family-owned companies, Lambertus  also advises on company succession as well as share and company sales. His training as a tax advisor enables him to understand complex tax processes together with tax law experts and implement them in interdisciplinary teams. In addition, Lambertus has a comprehensive understanding of business and accounting issues, which enables him to lead or support demanding post-M&A and valuation processes.

He advises family-owned companies, medium-sized enterprises, and listed public limited companies on restructuring and corporate succession matters, as well as in civil proceedings involving valuation or accounting issues, including severance payment claims, post-M&A disputes, and consultant liability proceedings.
