AI and Wills/Estates Forms Automation in Ontario: What's Actually There

Disclosure: DROZlegal publishes this guide and built the litigation form registry and wills-outreach agent described below. Third-party legal commentary here is sourced from Erin L. Watson, lawyer and notary public writing for E is for Estates, and from Brian Cohen & Maddi Thomas's coverage of Ontario's substantial-compliance doctrine for STEP Journal — verified for this article, not ours.

Say the limits out loud first

There is no estates model, service, or router anywhere in DROZlegal's backend, and zero estates routes in the frontend. If you're picturing an estate-planning intake wizard, a will-drafting assistant, or a dedicated probate-file workspace the way you'd picture DROZlegal's litigation case workspace, none of that exists. Nothing below should be read as implying otherwise.

What exists is two narrow, real things: a set of Ontario court forms sitting inside the litigation module's form registry, and one outbound business-development tool. That's the whole estates surface area today.

Why the formalities matter, AI or not

A will is only as good as its execution, and Ontario's Succession Law Reform Act is specific about what that requires: the testator's signature at the end of the document, witnessed by two people present together (or, since Bill 245's 2022 reforms, virtually present under strict conditions). Get the signing or witnessing wrong and the document can fail outright, regardless of how well the language reads.

Ontario lawyer Erin L. Watson, writing on AI and will-drafting, doesn't hedge on this: "Errors in signing or witnessing can render a Will invalid," and if an AI-drafted document "fails to achieve your intentions or contains errors, there is no recourse" — AI, as she puts it, "cannot assess your specific circumstances or stand behind its recommendations." A polished document is not the same thing as a valid one.

There is a safety net in Ontario law, but it's narrower than people assume. SLRA s.21.1, added by Bill 245, lets a court validate an imperfectly executed will if it's authentic and clearly reflects the deceased's final intentions — a two-part test Ontario courts have applied since 2023. It has real limits, though:

Ontario's substantial-compliance rule under SLRA s.21.1 can validate an imperfectly executed will — but it does not reach a purely electronic document, and it only covers deaths after January 1, 2022. — Brian Cohen & Maddi Thomas, "Substantially compliant," STEP Journal, 2025

That gap is exactly why forms and execution mechanics matter more, not less, once AI enters a wills/estates workflow: a well-drafted document that never gets properly signed and witnessed doesn't automatically get rescued by the courts. This is the backdrop the rest of this post sits against.

What's actually in the litigation form registry for estates

Rule 74 and Rule 75 of the Rules of Civil Procedure govern probate applications and contested estates in Ontario, and 54 of the forms those rules require are catalogued inside DROZlegal's litigation module — the same form registry a firm already uses for civil motions, notices, and affidavits, covered generally in our guide to Ontario court-form automation. Ten of the 54 sit in the platform's 25-form MVP generation set:

Those ten cover the core of an uncontested Ontario probate file: the originating 74A application, the small-estate track (74.1A), notice to beneficiaries or heirs-at-law (74.43/74.45), proof of service (74B), the affidavits that support execution of the will itself (74D, 74E, 74F), and the two forms that come up once an estate trustee is passing accounts or facing an objection (75.7, 75.12). All 54 estate forms — including the ones outside the MVP set — are findable the same way every other litigation form is: by browsing the form registry a firm already has open for its civil matters. There is no separate estates search, filter, or landing page.

The wills-outreach agent: what it is, and what it isn't

The one piece of code with "wills" in its name that touches AI generation directly is WillsOutreachAgent, and it is a business-development tool, not a drafting tool. It does one job: find CRM contacts linked to a wills/POA matter whose will is more than five years old, or who've gone dormant, and draft a short, personalized re-engagement email — "your will was last reviewed in 2019," for instance — recommending a review consultation.

Every draft it produces lands with status='planned'. The agent's own system prompt is explicit that it must never send anything and must never give legal advice in the outreach copy; a person has to read, approve, and send each one. It's reachable at /agents/wills-outreach, and that page is exactly what it does — a campaign-drafting tool, not a client file, not an intake flow, and not a way to produce a will.

One more honest note: three AI analysis prompts for wills/estates work — will-validity review, Power of Attorney review, and an estate-administration checklist — exist in the codebase. None is wired to a standalone client-facing feature. Only the will-validity prompt actually runs anywhere today, as background context inside the outreach agent's drafting prompt; the POA-review and estate-administration-checklist prompts are defined in the same file but aren't called by any route or agent. Useful groundwork, not a shipped analysis tool a lawyer can open and use on a file.

Who this is actually useful for

If your firm has a dedicated wills/estates practice built on a probate-administration platform, this isn't a replacement for that — DROZlegal doesn't compete there today, and pretending otherwise would be the kind of overclaim this post exists to avoid.

Where it's genuinely useful: a general-practice or litigation firm that handles the occasional estate file — a probate application here, a passing-of-accounts there — and already runs its litigation matters through DROZlegal. That firm doesn't need a second product, a second login, or a separate estates workflow to reach 54 Rule 74/75 forms. They're already sitting in the same registry as everything else. It's a narrow value proposition, on purpose — the same honest scoping we used opening our personal injury records-tracking coverage, another area where DROZlegal's footprint is real but deliberately not a full practice module yet. Both live behind the same propose-then-approve discipline — a form gets found, an outreach draft gets written, but a lawyer decides what happens next — that our Lawyer AI Academy guide walks through. The estate forms specifically live inside the litigation module's form registry; PI records-tracking runs as its own separate, narrow module — not part of litigation, and not a full practice platform either.

Update, September 17, 2026: the forms-registry coverage above is only half of what a firm should check before buying AI tooling for estates work. The execution and deadline rules matter just as much — a will still needs a wet-ink signature under the Succession Law Reform Act even when witnessing happens over video, and the Estate Information Return has its own 180-day filing clock separate from anything the form registry tracks. Our companion post, the AI vendor checklist for an Ontario wills & estates practice, covers those execution and deadline questions directly.
