You Cannot Arbitrate a Will Dispute in New Jersey
Can a testator include an arbitration clause in their Will that forces beneficiaries to resolve disputes in a private arbitration forum rather than a New Jersey court? For the first time, the New Jersey Appellate Division has answered that question directly — and the answer is no.
In a case published on April 21, 2026, In re Estate of Samuel P. Hekemian, the Appellate Division held that an arbitration provision contained in a Last Will and Testament is unenforceable under New Jersey law.
Background: The Hekemian Family Estate
Samuel P. Hekemian died testate in August 2018, survived by his wife Sandra and their four adult sons: Peter, Jeffrey, Mark, and Richard. His 2002 Last Will and Testament (2002 LWT) appointed his son Peter and longtime advisor Edward G. Imperatore, Esq. as co-executors and co-trustees of three testamentary trusts established under the Will.
The 2002 LWT contained an arbitration clause providing that any dispute regarding the interpretation of the Will or its administration “shall be submitted for settlement by arbitration.” The clause declared arbitration to be “the exclusive remedy” for resolving such disputes and stated that the arbitrator’s decision “shall be final and binding upon all interested parties and shall not be appealable to any court of law.”
The same arbitration provision appeared in reciprocal Wills executed simultaneously in 2001 by Samuel and Sandra that were prepared by the same New York attorney. When Sandra and Richard later filed exceptions to the co-executors’ first intermediate accounting of the estate, the co-executors moved to compel arbitration.
A Second Look at the Same Arbitration Clause
This was not the first time the arbitration provision had been challenged. In an earlier unpublished opinion, the Appellate Division had affirmed the denial of a motion to compel arbitration of Richard’s request for an accounting, finding that the clause was not the product of mutual assent under traditional contract principles and that it failed to explain that Richard was relinquishing his right to bring a claim in court. At that time, however, the court stopped short of declaring the arbitration provision categorically unenforceable.
In the intervening period, Sandra joined the litigation and filed her own exceptions to the co-executors’ accounting. Unlike Richard, Sandra had received distributions under the 2002 LWT. The co-executors argued this distinguished her situation and that her participation in the Will’s benefits, combined with the execution of the reciprocal 2001 Wills, established the mutual assent necessary to compel her to arbitrate. The trial court rejected that argument and denied the motion. The co-executors appealed.
The Court’s Holding: Two Independent Grounds
The Appellate Division affirmed the trial court’s denial, but went further than the lower court by issuing a definitive ruling on a question of first impression: arbitration clauses in testamentary instruments are unenforceable under New Jersey law. The court rested its holding on two independent and mutually reinforcing grounds.
1. Lack of Mutual Assent
An agreement to arbitrate, like any contract, requires mutual assent — a knowing and voluntary waiver of the right to pursue claims in court. The court reaffirmed its earlier conclusion that the arbitration clause failed to explain, in clear and unambiguous terms, that interested parties were relinquishing their right to sue. Citing Atalese v. U.S. Legal Servs. Grp., L.P., 219 N.J. 430 (2014), the court emphasized that “the point is to assure that the parties know that in electing arbitration as the exclusive remedy, they are waiving their time-honored right to sue.”
The co-executors argued that Sandra’s simultaneous execution of a reciprocal Will containing the same arbitration clause demonstrated her assent. The court rejected this. While a meeting of the minds is not required for a Will to be effective — because a Will is a unilateral disposition of property, not a contract — that principle cuts in the opposite direction for arbitration purposes. Precisely because a Will is unilateral, neither Sandra nor any other interested party was afforded the opportunity to consider or elect to waive their right to proceed in court. The court was not satisfied that the simultaneous execution of reciprocal Wills, without more, established the kind of informed, knowing assent required for a valid arbitration agreement.
2. Inconsistency with the Probate Code
Even if the assent problem could be overcome, the court held that arbitration clauses in Wills are incompatible with New Jersey’s statutory framework for estate administration. The Probate Code, N.J.S.A. 3B:1-1 et seq., vests the Superior Court with comprehensive authority over Will disputes, trust administration, and fiduciary accountings. The court catalogued the relevant provisions, including but not limited to:
- N.J.S.A. 3B:2-2 grants the Superior Court "full authority to hear and determine all controversies respecting wills, trusts[,] and estates, and full authority over the accounts of fiduciaries, and also authority over all other matters and things as are submitted to its determination under this title."
- N.J.S.A. 3B:3-17 during probate, the Superior Court "may take depositions to wills[,] admit the same to probate, and grant . . . letters testamentary or letters of administration with the will annexed."
- N.J.S.A. 3B:3-18 requiring that to "prove the transfer of any property or to nominate an executor, a will must be admitted to probate."
Against this backdrop, the court reaffirmed and expressly adopted what had been an observation in its prior unpublished opinion: “arbitration clauses that eliminate the courts’ expected role in resolving Will disputes are inconsistent with the detailed statutory scheme vesting the superior courts with the authority to adjudicate such issues.” Accordingly, enforcement of an arbitration clause in a testamentary instrument is contrary to both the Probate Code and New Jersey’s contract principles. The court held:
We conclude enforcement of an arbitration clause in a testamentary instrument is contrary to the court’s role underlying the Probate Code and inconsistent with our State’s contract principles.
What This Means for Estate Planning in New Jersey
The Hekemian decision settles a question that had been lingering in New Jersey estate practice for years. Estate planners and their clients should take note of several practical implications.
- Arbitration clauses in Wills are unenforceable in New Jersey. Regardless of a testator’s intent, an arbitration provision in a Last Will and Testament cannot compel beneficiaries, heirs, or other interested parties to resolve their disputes outside of court. Any such provision should be considered a nullity.
- Testamentary trusts are also covered. The court’s holding extends to disputes concerning trusts created under a Will, not merely the Will itself. The arbitration clause in the Will purported to cover disputes “regarding the interpretation of this Will and the trusts created hereunder” — both were held unenforceable.
- The result is the same regardless of mutual assent. Even if a testator and their spouse executed reciprocal Wills containing identical arbitration clauses, and even if the surviving spouse received benefits under the Will, that is insufficient to establish the knowing, voluntary waiver of court rights required under Atalese.
- Inter vivos trusts are a different question. The Hekemian decision addresses testamentary instruments — Wills and trusts created by Wills. Arbitration clauses in standalone inter vivos trusts, which are contractual instruments, may be treated differently.
- Will disputes belong in court. Beneficiaries and interested parties who find themselves in estate disputes in New Jersey have a right to litigate those disputes in the Superior Court, Chancery Division, Probate Part — and a testator cannot take that right away through a provision buried in their Will.
A Practical Note for Families
For families navigating an estate dispute in New Jersey, the Hekemian decision is significant. If a co-executor or trustee attempts to invoke an arbitration clause in a Will to divert your dispute out of court, that clause is unenforceable. You are entitled to pursue your claims — whether exceptions to an accounting, removal of a fiduciary, or other relief — in the Superior Court under the full protections of New Jersey law.
For those in the estate planning process, this decision underscores the importance of working with an experienced New Jersey estate planning attorney who stays current with developments in the law. Estate planning documents should reflect the current legal landscape, not aspirational provisions that courts will not enforce.
