Understanding both the financial and personal elements of a family is essential to ensuring that a client’s estate plan reflects their unique circumstances. Marni works closely with her clients to provide them with practical, thoughtful advice regarding their estate plan.

Clients appreciate Marni’s strong relationship-building skills and reputation as a thought-leader, and trust her because they are comfortable confiding in her and confident in her ability to advise them effectively. As Co-Practice Group Leader of the firm’s Tax Group and Estates & Trusts Group, and a member of the Estates & Succession Planning Group, Marni’s practice focuses on estate, income tax and succession planning, including cross-border planning, planning to reduce estate administration tax (formerly known as probate fees), the preparation of wills, powers of attorney and trusts, and assisting with estate administration. Additionally, Marni advises clients on how to reduce personal and corporate tax, including the effective use of a family trust.

Marni offers thoughtful and effective planning for clients ranging from young families who are just starting out to multi-generational families who are looking for effective ways to transition assets to the next generation. Marni enjoys navigating the complexities that arise in complicated and layered family structures, such as the dynamics that are present in blended families. Marni also has significant experience with cross-border planning for clients who have U.S. or other foreign connections.

Marni frequently writes and speaks on topics involving tax, estate planning and business succession planning for audiences such as insurance and financial advisers, accountants, professionals, and fellow lawyers.
