Markus Christmann is the Principal Solicitor of Asquith Legal, advising individuals, families and privately held enterprises across the Illawarra and beyond on estate planning, succession, probate and the legal challenges that arise when wealth and families span generations — and borders.
His practice focuses on Wills & Estates, Estate Planning, Cross-Border Succession, Probate & Estate Administration, and Estate Litigation. Markus regularly assists clients with complex succession planning involving international assets, blended families and multi-generational wealth, helping them structure their affairs to protect what they have built, provide certainty for those they love and navigate estates that cross legal jurisdictions.
Markus holds dual legal qualifications, admitted as a solicitor in both New South Wales and an overseas jurisdiction, and advises clients in English and German. This gives Asquith Legal a distinctive capability in cross-border estate and succession matters for clients with assets or family connections in Europe and beyond.
His practice also extends to the legal needs of artists and creative professionals, encompassing copyright succession, moral rights, digital assets and the careful stewardship of creative estates — an area requiring both technical legal knowledge and genuine appreciation for the unique nature of creative legacy.
Through Asquith Legal, Markus works closely with families, ageing clients and cross-border families to deliver clear and practical legal strategies across:
- Estate Planning & Succession
- Wills & Estates (NSW)
- Cross-Border Succession
- Probate & Estate Administration
- Testamentary Trusts
- Artist Estates & Creative Legacy Planning
Markus focuses on providing strategic, technically sound advice that helps clients protect their legacy, transition assets between generations and navigate complex international and personal circumstances with clarity and confidence.
