Trust and Estate Litigation


Client Challenges and Opportunities

When a person creates an estate plan, there is often an assumption that his or her estate will be administered exactly as intended and without dispute. Unfortunately, that is not always the case.  Diminished capacity, blended families, sibling rivalries, unfamiliarity with will and trust formalities as between different states, and the vast amount of wealth in trusts today all contribute to increased trust and estate litigation. Even before the primary wealth-holder passes, family members sometimes initiate pre-death tactics, such as filing guardianship or conservatorship actions.

Snell & Wilmer has an experienced, multijurisdictional team capable of representing clients in all types of trust and estate controversies. We understand trust and estate litigation is different than other forms of litigation, such as commercial litigation. Our team includes litigation attorneys who focus on trust and estate litigation, as well as Private Client Services attorneys. Our trust and estate litigation attorneys have extensive trial experience in trust and estate controversies throughout the United States. Our Private Client Services attorneys have a depth of experience in trust and estate administration, fiduciary standards, beneficiary rights, creditor rights, estate planning, and state and federal taxation of trusts, estates and individuals.

Trusts and estates frequently hold illiquid business interests and other unique assets. As a result, trust and estate litigation can involve a wide range of legal issues. As a full service law firm, Snell & Wilmer has the depth of knowledge to build the right team to suit any matter, including attorneys who focus on real estate, finance, tax, corporate and securities, governmental regulations, blockchain and digital currency, and intellectual property.

Why Clients Select Us

Client-Focused: We have a thorough understanding of trust and estate disputes, including how and why they emerge and strategies to defuse and avoid them. We strive to help our clients find practical and effective solutions to trust and estate controversies while avoiding unnecessary conflict and expense when possible.

Efficient: Some law firms only represent clients in trust and estate matters that are uncontested. Other law firms only represent clients in trust and estate matters when litigation is existing or imminent. However, we do both. We cost-effectively represent our clients in matters ranging from uncontested administrations to complex, multi-state litigation. We staff matters based upon type and complexity; and we remain flexible and attentive, so when an uncontested matter transitions to a contested matter, or vice versa, we efficiently adjust our staffing and continue the representation without disruption.

Multijurisdictional Footprint: Our trust and estate litigation attorneys have trial experience and practice in state and federal courts across the country. Our Private Client Services attorneys are also experienced in trust and estate administration in multiple jurisdictions, as well as the taxation of trusts, estates and individuals. We have locations throughout the Western United States, and in Washington, D.C. and Mexico. For corporate fiduciaries, we are able to provide coherent legal advice across multiple jurisdictions and better anticipate developing trends. 

Dedicated and Involved: Our attorneys are active lecturers and writers, appearing in the local and national press, sharing their knowledge in legal seminars, participating in the American Bar Association’s Probate and Fiduciary Litigation Committee and the Probate and Trust sections of individual state bar associations. Our trust & estate litigation attorneys have also been nationally recognized by Best Lawyers in America, Martindale-Hubbell and Super Lawyers.
