Vicki Ammundsen, Director and Notary Public, Vicki Ammundsen Trust Law
Vicki is the director at Vicki Ammundsen Trust Law Limited, which she established in 2015. Vicki is also the author of a number of books on trusts and trustees including Taxation of Trusts, ed 5, Trustee Liability, ed 2 and the Trustee’s Handbook, ed 5 (all published by Wolters Kluwer). She has presented at conferences in New Zealand and internationally on trust-related topics. Vicki also writes the blog Matters of Trust, which is a valuable trust and estate law resource. Vicki uses her day-to-day experience with trusts and estates and her deep knowledge of relevant case law to underpin her practical, solutions-focussed approach to dealing with a range of matters touching on trusts and estates. She firmly believes that trusts have an important role to play in inter-generational asset management, but that this is risked by a lack of understanding of effective or appropriate trust management that too often leads to misunderstanding or abuse.
