Lonneke S. Timmermans

Lonneke Timmermans is a renowned Dutch family law lawyer, divorce mediator, and collaborative divorce lawyer. She mostly assists successful entrepreneurs and high-net-worth individuals in complex divorce proceedings. Lonneke is a recognised expert when it comes to settling prenuptial agreements, non-marital relationships, and alimony cases. She regularly litigates in relocation cases and Article 1:160 of the Netherlands Civil Code cases. Her drive in getting her clients to divorce their partners in as harmonious a manner as possible – achieved through consultation, mediation, and collaboration – has prevented many cases coming to court and divorces becoming mired in acrimony. Lonneke is also an estate mediator. With inheritance law specialist Petra Knoppers, she acts as a mediator (or co-mediator) in cases involving deaths.

Lonneke completed her Dutch law degree at Tilburg University in 1999, after which she worked as the senior judicial assistant in the ’s Hertogenbosch and Amsterdam District Courts. In 2001, Lonneke started work in the legal profession itself, first at Rassers Advocaten in Breda, where she specialised entirely in personal and family law. She then moved to AKD Prinsen Van Wijmen, where she worked in the Personal and Family Law section before joining SmeetsGijbels in 2007. Lonneke set up SmeetsGijbels’ Amsterdam office in 2009. She has been a SmeetsGijbels partner/shareholder since 1 July 2011.

Lonneke is a member of the ‘Nederlandse vereniging Familie- en erfrecht Advocaten Scheidingsmediators’ (vFAS), of which association she was a board member for four years. Additionally, Lonneke is a member of the Association of Collaborative Professionals (VvCP) and has been added to the register of the ‘Stichting Nalatenschapsmediation’ foundation. She is also a member of the editorial team of the ‘Relatierecht en Praktijk’ (REP) trade journal. Lonneke writes for various publications on family law topics and regularly appears as an expert on television and radio. As well as giving courses on her field to lawyers, Lonneke also delivers lectures to accountants and tax advisors. Lonneke is a member of the Founders Carbon Network (FCN).
