Trust Disputes: Legal Options for Resolving Conflicts Among Beneficiaries

Trusts are often established to prevent conflict, protect privacy, and provide a smooth transfer of assets to loved ones. However, despite careful planning, trust disputes can and do arise, particularly when emotions run high, assets are significant, or instructions appear vague or unfair.
When disagreements occur between beneficiaries or between beneficiaries and trustees, it's essential to understand the legal remedies available and how best to protect your interests while preserving the integrity of the estate.

Whether you're a beneficiary, trustee, or concerned third party, it’s critical to know how trust disputes arise, what legal options you have, and how these matters are typically resolved.
Before examining your legal options, it's helpful to understand the underlying causes of conflict. Trust disputes often result from one or more of the following issues:
Some trust documents contain ambiguous language or provisions that are open to interpretation. If beneficiaries interpret the trust’s intent differently—or if trustees believe they have discretionary authority—disagreements can escalate quickly.
Trustees are fiduciaries, meaning they have a legal obligation to act in the best interests of the beneficiaries and to administer the trust according to its terms. If a trustee is perceived to have breached that duty—whether by mismanaging assets, showing favoritism, failing to provide proper accounting, or engaging in self-dealing—beneficiaries may seek legal intervention.
When one beneficiary receives more than another, or when a previously promised inheritance fails to materialize, tensions can rise. Allegations of undue influence, fraud, or diminished mental capacity often accompany these disputes.
Trustees are typically required to provide regular reports and maintain open communication with beneficiaries. If that doesn’t occur, beneficiaries may feel mistrust or assume wrongdoing, even in the absence of actual misconduct.
Sometimes, the cause of a dispute has less to do with the legal validity of the trust and more to do with strained personal relationships. Blended families, sibling rivalries, or unresolved resentment can all magnify trust-related conflicts.
When a conflict over a trust arises, the main players typically include:
Beneficiaries – Individuals or organizations that receive assets from the trust.
Trustee(s) – The person(s) or entity responsible for managing the trust and carrying out its terms.
Interested third parties – These may include omitted heirs, creditors, guardians, or agents under a power of attorney who claim an interest in the trust assets.
Understanding the role and obligations of each party is essential when developing a strategy for resolution.
While the terms of a trust are legally binding, they can be challenged in New York under specific circumstances. Some of the most common legal claims in trust litigation include:
If the trust creator (also known as the settlor or grantor) wasn’t of sound mind at the time the trust was executed, a court may find the trust invalid. Demonstrating a lack of capacity typically requires medical records, expert testimony, and credible evidence of confusion or cognitive decline.
This occurs when someone exerts excessive pressure on the grantor to benefit themselves, usually to the detriment of others who were previously entitled to inherit. Proving undue influence involves showing that the grantor’s free will was overborne by coercion, manipulation, or isolation.
A trust may be declared invalid if it was signed under false pretenses or if the signature itself was forged. These cases often require forensic document examiners and other forms of expert analysis.
If a trustee fails to carry out their duties with honesty, prudence, and loyalty, they may be held personally liable. Breaches can include misappropriation of funds, conflicts of interest, or failure to follow the trust terms.
New York beneficiaries and trustees have several legal pathways to resolve trust conflicts. Depending on the nature of the dispute, you may pursue one or more of the following remedies:
Many trust disputes can be resolved outside the courtroom through mediation or facilitated negotiation. This approach is often faster, less expensive, and more private than formal litigation. Mediation allows all parties to express their concerns in a structured setting to reach a mutually agreeable solution.
In New York, trust and estate disputes are typically handled in Surrogate’s Court. You may file a petition to:
Compel a trustee to account for their management of trust assets.
Remove a trustee for misconduct or incapacity.
Contest the validity of the trust.
Seek instructions on interpreting ambiguous terms.
Obtain injunctive relief to prevent mismanagement.
If a trustee has acted improperly, the court can suspend or remove them. The court may appoint a successor trustee or independent fiduciary to make certain the trust is administered properly going forward.
Beneficiaries can compel a formal accounting of the trust’s assets, liabilities, and transactions. If discrepancies are found, the trustee may be ordered to return funds, pay damages, or face sanctions.
If a trustee is found to have breached their fiduciary duties, they may be personally liable for losses suffered by the trust. A surcharge is a monetary penalty intended to make the trust whole.
If you’re a beneficiary involved in a trust dispute, consider the following steps:
Collect all trust-related documents, correspondence with the trustee, financial statements, and any communications that may support your position.
In New York, the time to bring a trust contest or breach of fiduciary duty claim may be limited. Delays in pursuing your claim could bar recovery entirely. Consulting with an attorney early can help preserve your rights.
Maintaining factual and respectful communication during trust disputes can help solidify your legal standing and avoid conflict.
Trust litigation can be expensive and time-consuming. Before proceeding, weigh the likely outcome against the costs, both financial and emotional.
If you’re a trustee facing allegations or conflict, it’s essential to:
Accurate and organized financial records, notes of meetings, and copies of correspondence can demonstrate that you acted prudently and in good faith.
Providing beneficiaries with regular updates, clear accounting, and timely responses can help reduce suspicion and prevent misunderstandings.
You must administer the trust impartially and avoid transactions that benefit you personally unless explicitly authorized by the trust terms or court approval.
As a fiduciary, you’re held to a high standard. Engaging legal counsel early in the process can protect both your personal liability and the integrity of the trust.
Trustees and beneficiaries increasingly turn to ADR options such as mediation and arbitration to resolve disputes without going to trial. Many modern trust documents include provisions that require ADR before litigation.
Mediation involves a neutral third-party facilitator and is non-binding unless the parties agree to a resolution.
Arbitration, by contrast, is more formal and results in a binding decision, similar to a court ruling.
ADR may offer benefits like confidentiality, reduced legal fees, and faster resolution—an appealing option for parties looking to safeguard family relationships or the value of the estate value.
While not every dispute can be avoided, there are steps that grantors and their advisors can take to reduce the likelihood of conflict:
Vague or overly complicated trust provisions create confusion. A well-drafted trust is explicit in its intentions, particularly regarding distribution terms, discretionary powers, and successor trustees.
In some cases, appointing a neutral third party, such as a trust company or attorney, can avoid personal conflicts and provide more professional administration.
While not legally required, discussing your estate plan with your heirs can provide clarity and reduce surprise or resentment later on.
Also known as in terrorem clauses, these provisions penalize beneficiaries who challenge the trust without probable cause. They can be effective deterrents, though not always enforceable in every situation.
Trust disputes are among the most delicate and emotionally charged matters in estate law. Whether you’re seeking to challenge a trust, defend your role as trustee, or simply need clarification about your legal rights, working with an experienced law firm is essential.
