UHNW Estate & Trust Disputes | Topics
Coming Soon
Family Office Disputes After Death or Incapacity
UHNW clients with family offices managing their affairs may run into disputes over how assets and estate interests should be managed, ambiguous estate planning documents should be interpreted, or who should assume control over estate decisions. The estate litigation attorneys at RMO LLP can help bring clarity to these disputes, addressing critical legal questions about how assets should be handled and advocating for the best possible outcome within the procedures established by the local probate courts.
Disputes Over Control of Family Businesses and Closely Held Companies
Managing business interests after a person passes away can be particularly challenging, as they are difficult to value and may involve multiple stakeholders, each with their own desired stake in the business. Navigating business succession disputes may require carefully reviewing estate planning documents, understanding state intestacy laws related to illiquid assets and addressing potential disputes through mediation. Our attorneys provide detailed representation throughout each step.
Trustee, Executor, and Fiduciary Misconduct in High-Value Estates
Acts of fiduciary misconduct and breach of fiduciary duty pose serious risks to high-net-worth estates, especially when fiduciaries mismanage expensive assets or engage in nefarious acts such as self-dealing. Irresponsible management of assets could result in a significant reduction of the value of assets or financial losses to the estate, with UHNW estates facing a particularly high risk. It’s important for beneficiaries and interested parties to remain informed about their rights and what important signs to look out for.
Removing or Replacing Trustees in Complex Trust Disputes
Beneficiaries have the right to remove a trustee who has acted with misconduct or failed to uphold their responsibilities to act in the best interests of the trust, to ensure the trust is administered in accordance with the decedent’s wishes. This process may depend on any terms specified in the trust as well as the laws set out in state probate codes. The attorneys at RMO LLP are prepared to support clients in these matters to help trustees understand their rights and the options available to them.
Trust Accountings and Financial Transparency in UHNW Trusts
In trusts involving high-value assets, it’s crucial that you have full transparency around how these assets are handled and managed. Beneficiaries have a right to demand trust and estate accountings, and it is a fiduciary’s obligation to provide them upon request. The attorneys at RMO LLP are a valuable resource for helping you understand and exercise your rights to ensure that you can access UHNW trust accountings and have a complete picture of how assets are being managed.

Valuation Disputes Involving Businesses, Real Estate, Art, and Complex Assets
In cases involving complex, high-value assets such as business interests, investment accounts, cryptocurrency, art, and similar forms of property, interested parties may disagree over how these assets should be valued and the shares of the inheritance they will receive. Navigating the valuation of complex assets requires consulting a skilled appraiser, clarifying inheritance shares based on a careful review of any existing estate planning documents and possibly resolving disputes through mediation.
Undue Influence, Capacity, and Late-Life Estate Plan Changes
Credible concerns of undue influence or fraud in the creation or alteration of a trust or estate planning document may provide interested parties with valid grounds to contest a will or trust. High-value estates are often especially susceptible to undue influence and fraud, as interested parties may attempt to take advantage of a vulnerable individual to access their expensive assets. Our attorneys represent interested parties in pursuing legal action if they suspect that a bad actor is jeopardizing their loved one’s interests.
Blended Family and Second-Spouse Estate Disputes
Divorces and second marriages can create sensitive family disagreements as there may be past renditions of estate planning documents or conflicting interests in who should receive a share of specific assets, which may call the distribution of an inheritance into question or invoke dynasty trust litigation. Our UHNW trust litigation attorneys at RMO LLP have considerable experience in estate matters involving blended families to help you understand the implications of omitted spouses, pretermitted heirs, spousal inheritance rights and more.
Disputes Involving Powers of Attorney, Conservatorships, and Financial Elder Abuse
In UHNW estates, it is unfortunately not uncommon for bad actors to attempt to take advantage of vulnerable elders for personal gain through arrangements like power of attorney appointments, conservatorships, or caretaking relationships. Interested parties may contest arrangements like a conservatorship or a power of attorney if they believe a bad actor is using their position of authority to exhibit financial elder abuse. Our attorneys assist interested parties in these UHNW trust disputes in upholding their rights and protecting their loved one’s legacy.
Privacy, Reputation, and Confidentiality in High-Profile Estate Litigation
When filing for litigation, key details about the case and the family estates involved are made public. Maintaining privacy in UHNW estate disputes is an important concern, especially for families with substantial assets who don’t want their personal business exposed to the world. Whether it’s the option to create a trust or to resolve disputes outside of the courtroom through mediation, RMO LLP will help you understand your options for preserving your privacy and resolving disputes without disclosing vulnerable personal matters.
Multi-State and Cross-Border Trust and Estate Disputes
UHNW estates frequently involve a substantial number of assets that exist across state and international borders. It’s important to have an experienced attorney who understands how to navigate probate across multiple jurisdictions and has a strong professional network of international attorneys and financial experts. The attorneys at RMO LLP have considerable experience in estate and probate disputes that extend across multiple jurisdictions and maintain global reach to advocate for clients in the most difficult of UHNW estate disputes.
