AI-Generated Wills and Estate Planning Documents — 8 Things NJ Solo Attorneys Must Check Before They Leave the Office

Estate planning is quietly becoming one of the highest-volume use cases for AI document automation in solo law practices. It's easy to see why: wills, powers of attorney, and healthcare directives are structurally repetitive, client intake is data-heavy, and a solo attorney producing fifty estate plans a year stands to recover dozens of billable hours by letting an AI tool assemble the first draft.

But repetitive does not mean low-stakes. In New Jersey, a single drafting error in a will — a missing witness signature block, a defectively executed self-proving affidavit, or a beneficiary designation that conflicts with a separately titled asset — can unravel a client's estate plan entirely, and the attorney responsible won't know it until the client is gone and the family is litigating. AI tools don't attend funerals. You do.

Before your AI-drafted estate planning document goes anywhere near a client signature, run through these eight checks. They are sequenced in the order most likely to catch errors before they compound.

1. Verify NJ Execution Formalities Are Hardcoded, Not Templated Generically

New Jersey's will execution requirements under N.J.S.A. 3B:3-2 require the testator's signature and two witnesses. Many AI tools pull from multi-jurisdictional template libraries. Confirm that your tool is generating signature blocks and attestation language specific to New Jersey — not a Delaware or generic UPC-state version. Check this in the raw output, every time, until you trust the tool's jurisdiction logic completely.

2. Cross-Reference Beneficiary Designations Against Titled Assets

AI tools draft what you feed them. If your intake form doesn't surface a client's 401(k), life insurance policy, or jointly held real estate, the AI won't account for those assets in the residuary clause — and no amount of prompt engineering fixes a gap in intake data. Before finalizing any AI-drafted will, run a quick asset-and-beneficiary reconciliation. Mismatches between the will and a beneficiary designation form are invisible to the AI and are among the most common causes of post-death litigation.

3. Confirm the Healthcare Directive Tracks Current NJ Advance Directive Statute

New Jersey's Advance Directive for Health Care Act (N.J.S.A. 26:2H-53 et seq.) sets specific requirements for proxy designation and declaration language. This statute has been amended, and older AI training data may reflect prior versions. Spot-check the statutory language, proxy authority scope, and witness requirements against the current statute each time — not just when you onboard a new tool.

4. Check for Internal Document Contradictions

A will that names an executor in one clause and a different person as "personal representative" in another is a product of an AI that lost thread coherence across a long document. This happens. Read for internal consistency: executor/personal representative naming, trustee succession, and guardian nominations should be singular and consistent throughout. Don't outsource this read to another AI — it requires human attention to the document's own logic.

5. Audit Trust Provisions for NJ Rule Against Perpetuities Compliance

New Jersey has modified but not abolished the rule against perpetuities. Any testamentary trust with a duration tied to a life in being should include a savings clause that references NJ's statutory framework. AI tools frequently generate trusts with savings clauses calibrated to other states' perpetuities rules. Confirm the savings clause is jurisdictionally correct.

6. Confirm Power of Attorney Language Meets the NJ Uniform Power of Attorney Act

New Jersey adopted a version of the Uniform Power of Attorney Act (N.J.S.A. 46:2B-8.1 et seq.). AI-generated POA documents sometimes default to older "durable power of attorney" statutory language that predates the current act. Verify that the durability language, agent authority grants, and acknowledgment requirements align with the current NJ statute — not a predecessor version or a model act the AI was trained on.

7. Look for Missing Per Stirpes / Per Capita Clarity

Ambiguous distribution language is one of the most common AI drafting failures in estate documents. An AI tool will often generate "to my descendants" without anchoring the distribution scheme to per stirpes or per capita with representation. In a contested estate, that ambiguity is expensive. Require the AI output to explicitly state the distribution method, and review it against the client's expressed intent from intake.

8. Run a Final Malpractice Lens: Would This Hold Up If the Client Died Tomorrow?

This is not a checklist item — it is a mindset. Before you send any AI-drafted estate plan to a client for execution, ask yourself the uncomfortable question: if this client passed away this week, would this document accomplish what they told me they wanted, in a way that a NJ probate court would enforce? If you feel any uncertainty, that uncertainty is your professional signal to pause, research, and revise.

The Practical Upshot for NJ Solo Practitioners

AI document automation for estate planning is legitimate, efficient, and increasingly competitive to offer. But the efficiency dividend only materializes if your quality-control layer is fast and reliable. A firm-specific checklist — one tailored to the AI tool you actually use, the intake form you actually run, and the NJ statutes that actually govern — is not overhead. It is the thing that turns AI output into legal work product you can stand behind.

Build the checklist once. Run it every time. That's the whole discipline.
