When the estate plan fails, the person who could have fixed it is already gone.

Your mother told you, more than once, that the house was going to you and your sister equally. She paid a lawyer to make that happen. Then she died, the will came out of the drawer, and the residuary clause -- the one paragraph that was supposed to carry the house -- didn't say what she said it would say. Or the trust she signed to keep the house out of probate never had the deed recorded into it. Or the disclaimer that would have saved the family a six-figure tax bill needed to be filed within nine months, and nobody told anyone until month eleven.

Estate malpractice has a structural cruelty the other kinds don't: the client who could have corrected the mistake is gone before anyone finds it. The lawyer's error sits latent in a file cabinet for years, and it detonates at probate, in front of a grieving family, when no codicil can fix it. We handle these cases as part of our New Jersey legal-malpractice practice -- suing the negligent lawyer on behalf of the people the plan was supposed to protect. We are not interested in convincing you to file a lawsuit you do not have. A defeated expectation is not automatically a claim. But when the lawyer's file shows the testator asked for one thing and the documents did another, New Jersey law provides a path, and it was substantially clarified in 2026.

Who can sue matters more here than anywhere else in legal malpractice.

In most malpractice cases the plaintiff is the former client. In estate cases the former client is dead, and the people actually harmed -- the beneficiaries who received less than the testator intended -- never signed the retainer. Defense counsel's first motion in nearly every one of these cases says the same thing: no attorney-client relationship, no duty, no case.

New Jersey rejected strict privity decades ago. In Petrillo v. Bachenberg, 139 N.J. 472 (1995) source , the Supreme Court held that a lawyer may owe a duty to a non-client who the lawyer knows, or should know, will rely on the lawyer's work, so long as the non-client is not too remote. That reliance principle carried disappointed-beneficiary claims for thirty years, case by case, without a single controlling framework.

The framework arrived in January 2026. In Christakos v. Boyadjis, 262 N.J. 447 (2026) source , a will-drafting malpractice case, the New Jersey Supreme Court adopted the standard of Section 51 of the Restatement (Third) of the Law Governing Lawyers as the test for when an attorney owes a duty to a non-client, applying Sections 51(2) and 51(3). Two paths now exist:

• Invited reliance -- the lawyer (or the client with the lawyer's acquiescence) invited the non-client to rely on the lawyer's opinion or services, the non-client relied, and the non-client is not too remote.
• Intended beneficiary -- the lawyer knew that one of the client's primary objectives was to benefit the non-client, imposing the duty would not significantly impair the lawyer's obligations to the client, and without the duty those obligations would likely go unenforced. A beneficiary claiming the lawyer failed to carry out the testator's intent must prove the lawyer's knowledge of that intent by clear and convincing evidence.

The clear-and-convincing standard is a real gate, and Christakos itself shows it closing: the Court found no duty to the testators' niece where the evidence did not clearly establish that the drafting lawyer knew the testators intended their wills to benefit her. The Court also rejected duty theories built on the testator's alleged lack of capacity -- a family member cannot sue the drafting lawyer for preparing a will the family member thinks the testator was too impaired to sign. What survives, and survives well, is the core disappointed-beneficiary case: the will names you, or the lawyer's file shows the testator instructed that you be provided for, and the documents as drafted failed to do it. That is the evidence we go looking for first, and it lives in the drafting lawyer's own file -- intake notes, correspondence, prior wills, drafts with margin comments.

Drafting errors that defeat the testator's intent.

The estate plan is a machine built to run exactly once, unattended. Drafting errors are defects that stay invisible until the single moment of operation. The patterns we see in New Jersey files:

• Execution failures -- a will signed without the two witnesses required by N.J.S.A. 3B:3-2 source , witnessed improperly, or never signed at all because the lawyer let the file sit. New Jersey's harmless-error statute, N.J.S.A. 3B:3-3 source , can rescue a defective document where clear and convincing evidence shows the decedent intended it as a will -- but the rescue litigation itself is expensive, uncertain, and frequently a consequence of the drafting failure. The cost of the curative fight can itself be a damages element.
• Dispositive language that does not do what the testator asked -- a residuary clause that lapses, a per stirpes/per capita confusion that redistributes shares among grandchildren, a charitable bequest that misnames the charity, a specific devise of property the testator no longer owned at death.
• The plan and the titling in conflict -- the will leaves the brokerage account to one child while the account's beneficiary designation, never reviewed, pays it to another. Beneficiary designations and joint titling pass outside the will; a drafter who builds a plan without checking how the assets actually pass has planned around assets the plan does not control.
• Stale documents the lawyer was engaged to update -- the divorce that should have triggered a redraft, the after-born child never added, the update the client requested and paid for that never got signed before death.
• Tax-apportionment silence -- New Jersey's inheritance tax under N.J.S.A. 54:34-1 source et seq. still taxes bequests to siblings, nieces, nephews, and non-relatives even though the separate New Jersey estate tax was eliminated for deaths after January 1, 2018. A will that never says who bears that tax can shift the burden onto the wrong beneficiary, contrary to everything the testator said in the planning meetings.

In each pattern the proof problem is the same: the testator cannot testify. The case is reconstructed from the drafting file, prior wills, the lawyer's notes and billing entries, and the witnesses who heard the testator's instructions. That reconstruction is the estate-malpractice version of the case within a case -- proving what the plan would have said, and what you would have received, had the lawyer done the work competently.

Missed tax elections and disclaimers -- the deadlines that quietly cost six figures.

Post-death planning is where estate lawyers earn their fee and where the calendar shows no mercy. Three windows account for most of the malpractice we see in this category:

• Qualified disclaimers. A beneficiary can redirect an inheritance -- often to a surviving spouse, a credit-shelter trust, or the next generation -- with a disclaimer that is qualified for federal transfer-tax purposes only if it meets 26 U.S.C. § 2518 source : in writing, delivered within nine months, before the beneficiary accepts any benefit of the property. New Jersey's disclaimer statute, N.J.S.A. 3B:9-2 source , is more forgiving on timing -- which is precisely the trap. A disclaimer valid under state law but late under federal law is a taxable gift by the disclaimant. Counsel who lets a client take a distribution check, or lets month nine pass while "reviewing options," may have converted a tax-free redirect into a tax event.
• Portability. The deceased spouse's unused federal estate-tax exclusion transfers to the survivor only if an election is made on a timely filed estate-tax return under 26 U.S.C. § 2010(c)(5)(A) source -- including estates too small to owe any tax, which is exactly why the filing gets skipped. The IRS has provided simplified late-election relief for certain portability-only returns, currently Rev. Proc. 2022-32 source (permitting the election on a return filed within five years of death), but relief has conditions and time limits of its own, and the malpractice question is why the election needed rescuing at all. When the surviving spouse's estate later exceeds one exclusion, the skipped election has a precise price.
• Marital-deduction elections. A QTIP election under 26 U.S.C. § 2056(b)(7) source that is made wrong, made late, or never made can strip the marital deduction from a trust that was drafted to qualify for it, accelerating tax the plan was built to defer.

These are, from a litigation standpoint, the strongest damages cases in estate malpractice: the harm is a tax computation, not a jury's estimate. The tax actually paid, minus the tax a competent practitioner would have achieved, plus the cost of the accountants and curative filings. One doctrinal caution belongs here. Barner v. Sheldon, 292 N.J. Super. 258 (Law Div. 1995), aff'd o.b., 292 N.J. Super. 157 (App. Div. 1996) source held that the estate's attorney owed beneficiaries no duty to recommend a disclaimer that would have saved taxes but contradicted the testator's intent -- there, a disclaimer would have redirected the children's inheritance to their mother, against the will's dispositive plan. The duty to advise on elections runs first to the lawyer's actual client, and the testator's documented wishes can cut off a beneficiary's claim. Whether it does on your facts is an analysis, not an assumption.

The trust that was never funded is the estate plan that never existed.

A revocable living trust avoids probate only for assets titled in the trust. An irrevocable trust starts its Medicaid lookback clock only when assets actually move. A special-needs trust protects a disabled child's benefits only if the inheritance lands in the trust rather than in the child's name. The document without the funding is a binder on a shelf.

Funding failures generally trace to one of three engagement breakdowns. The lawyer undertook the funding -- deeds, assignments, beneficiary-designation changes -- and did not finish it. The lawyer handed the client a to-do list without explaining that the entire plan depended on it, and the file shows no follow-up. Or the funding happened but was done wrong: a deed recorded with a defective legal description, a retirement account made payable to a trust without analyzing the income-tax consequences, an operating agreement that blocked the very membership-interest transfer the plan assumed. In every version, the retainer agreement and the file tell us whose job the funding was. When the family then loses the probate avoidance, the lookback position, or the benefits eligibility the plan promised, the difference is measurable -- and the drafting lawyer's own estate-planning file is usually the best evidence of what the plan was supposed to accomplish.

Errors by counsel to executors and trustees during administration.

Malpractice does not stop when the will is admitted. Lawyers guide executors and trustees through probate and estate administration -- inventory, creditor claims, tax returns, elections, accountings, distributions -- and negligent guidance at this stage produces its own casualties: distributions made before taxes were reserved, elections missed, deadlines for contesting or defending the will blown, self-dealing by the fiduciary that counsel watched and never flagged.

The threshold question is again who the client was. Estate of Albanese v. Lolio, 393 N.J. Super. 355 (App. Div. 2007) source is the instructive New Jersey specimen. An estate paid a federal estate-tax bill of more than $900,000 with IRA withdrawals distributed to the beneficiaries -- allegedly on counsel's advice, and at a claimed personal income-tax cost of roughly $298,000 to each of them. The Appellate Division held the lawyers owed no duty to the beneficiary sisters on those facts, but the executrix's own claim survived because the retainer agreement was ambiguous about whether counsel represented her individually as well as the estate. The lesson runs in both directions. If you are an executor or trustee who relied on counsel's advice and now faces surcharge exposure or personal tax damage, you are the client, and the claim is a conventional one. If you are a beneficiary, the path runs through the Christakos non-client framework -- or around the lawyer entirely, through a breach-of-fiduciary-duty action against the executor or trustee, where counsel's conduct becomes evidence and the fiduciary's own remedies against the lawyer come into play.

Scope note: We represent the clients and beneficiaries those attorneys harmed. We do not represent attorneys defending themselves against malpractice claims. Where a conflict prevents us from taking your case -- for example, if you were previously represented by an attorney with whom we have a current professional relationship -- we will say so during intake and decline the matter.

What has to be proved, and how we build it.

An estate malpractice case still rests on the four elements of every New Jersey legal-malpractice claim: a duty (to a client, or to a non-client under the Christakos framework), a breach of the standard of care, causation, and measurable damages. Two procedural gates come with it. The Affidavit of Merit under N.J.S.A. 2A:53A-27 source must come from an attorney in the defendant's specialty -- for these cases, a practitioner who actually drafts wills and administers estates. And the six-year statute of limitations under N.J.S.A. 2A:14-1 source interacts with the discovery rule in a way that dominates these cases, because the negligence often predates the discovery by a decade or more.

Practically, the build sequence looks like this. We obtain the drafting or administration file -- the testator's intake questionnaire, correspondence, drafts, billing entries -- because it is simultaneously the proof of intent, the proof of breach, and the proof of what the lawyer knew about the intended beneficiaries. We reconstruct the but-for estate: what each beneficiary would have received under a competently drafted and administered plan, including the tax computations. And we retain the same-specialty expert early, before filing, because an estate malpractice case without a credible trusts-and-estates expert is a case waiting to be dismissed. Where the negligent lawyer also charged the estate for the flawed work, the fees themselves are part of the damages analysis.
