Why an estates file breaks a generic AI-vendor checklist
Most AI-vendor checklists assume a signature is a signature. Estates practice is one of the few areas where that assumption is actually false. Bill 245 amended the Succession Law Reform Act's section 4 to permanently allow a will to be witnessed by audio-visual communication technology, effective January 1, 2022 (retroactive to April 7, 2020) — but the underlying document still has to carry a genuine wet-ink signature from the testator and both witnesses. E-signatures are not permitted on a will, full stop, and at least one of the two witnesses has to be an Ontario-licensed lawyer or paralegal if the signing happens virtually.
A vendor whose e-signature flow was built for a commercial services agreement has no reason to know any of that. Neither does a vendor's tax-calculation feature necessarily know that Ontario's Estate Administration Tax charges nothing on the first $50,000 of an estate and then $15 for every $1,000 above it, per the Ontario government's own published rate schedule — or that the Estate Information Return reporting that value has to reach the Ministry of Finance within 180 days of the Certificate of Appointment of Estate Trustee issuing, itemized down to the property assessment roll number and the bank account number of every asset. The ten questions below are the ones a wills and estates practice needs to ask that a generic checklist won't surface.
Group A — Execution and signing validity
This is the highest-stakes category: get it wrong and the will's validity itself is what's at risk, not just a compliance fine.
| # | Question | Why it matters | Red flag answer |
|---|---|---|---|
| 1 | Does the tool's e-signature or remote-execution workflow correctly refuse to let a will be signed electronically, insisting on a genuine wet-ink signature even when witnessing happens over video? | SLRA s.4 permits virtual witnessing, not virtual signing. A generic e-sign product built for commercial contracts has no reason to draw that line on its own — and a will executed with an e-signature instead of wet ink is vulnerable to a validity challenge. | The vendor says "we support e-signatures for all documents" without carving out wills specifically. |
| 2 | If the tool is used for a virtual signing, does it confirm that at least one of the two witnesses is licensed by the Law Society of Ontario, as SLRA s.4 requires for remote execution? | Two lay witnesses over video isn't sufficient for a remote signing under the current rule — one of the two must be an Ontario-licensed lawyer or paralegal. A workflow that doesn't ask who the witnesses are can't catch this. | The tool tracks that witnessing happened, but never records who witnessed or their licensing status. |
| 3 | Can the tool produce or preserve the counterpart-document record a virtual will-signing actually generates — the separate physical copies each remote party signs and later reconciles? | Virtual execution under the current rule relies on counterpart documents, not a single shared file. If the tool only has one version of the document, it isn't built for how a remote will-signing actually has to work. | "Everyone signs the same PDF" is the entire explanation of the process. |
Group B — Estate-specific deadlines and tax calculation
None of this is exotic law — it's routine estate administration. But it's routine only if the tool actually knows the numbers and the clock.
| # | Question | Why it matters | Red flag answer |
|---|---|---|---|
| 4 | Does the tool track, or at minimum flag, the 180-day deadline for filing the Estate Information Return once a Certificate of Appointment of Estate Trustee is issued? | The Ministry of Finance gives an estate trustee 180 days from the Certificate's issuance to file. Miss it, and the estate can be audited with no time limit at all — file on time, and the audit window is still up to 4 years. A tool with no deadline-tracking concept for this specific clock leaves that risk entirely on the trustee's memory. | The tool has generic task reminders but no estate-specific deadline type at all. |
| 5 | Does the tool calculate Ontario's Estate Administration Tax correctly — $0 on the first $50,000 of estate value, then $15 for every $1,000 (or part of $1,000) above that? | This is a published, fixed rate schedule per Ontario's own Estate Administration Tax page, not an estimate. A tool that gets the threshold or the rate wrong produces a deposit figure that's simply incorrect when the estate certificate application is filed. | The tool applies a flat percentage to the full estate value with no exemption for the first $50,000. |
| 6 | Given that the Estate Information Return requires asset-by-asset detail — a property's assessment roll number, a bank account's institution name and account number — does the tool actually structure estate assets at that level, or only track one lump-sum total? | A lump-sum estate value is useless for actually filing the return. The Return is itemized by asset; a tool that only stores a total forces the trustee to reconstruct the itemization from scratch anyway. | "Enter the total estate value" is the only asset-related field in the product. |
Group C — Fit with an aging client base and firm realities
| # | Question | Why it matters | Red flag answer |
|---|---|---|---|
| 7 | Does the tool's workflow flag fact patterns that estate litigation often turns on — for example, a will signed close in time to a diagnosis, hospitalization, or major cognitive-health event? | Capacity challenges are one of the most common ways a will ends up contested. A tool that has no concept of flagging this timing risk leaves the firm to catch it manually, every time. | The product has no field or prompt related to testamentary capacity at all. |
| 8 | Does conflict-checking search every named beneficiary, executor, and attorney for property or personal care across related files — not just the person listed as the "client"? | One family's estate plan routinely produces linked files — a will, two powers of attorney, sometimes a trust — naming overlapping people who were never each other's own client. A conflict check limited to the client-name field misses exactly this pattern. | Conflict search returns nothing unless the exact client name is typed into the query. |
| 9 | Is the tool's pricing and intake workflow actually built to scale with a growing caseload, not just a one-off file? | Statistics Canada's medium-growth population projection puts Canadians aged 65 and older at roughly 22.5% of the national population by 2030, up from about 14% in 2010 — the demographic driving estates work is growing steadily, not staying flat. A tool priced or designed only for occasional use doesn't fit a practice area that's about to see sustained volume growth. | Pricing only makes sense for a handful of files a year, with no volume-based tier. |
| 10 | Will the vendor tell you plainly what it does not do yet for estates specifically — before you're mid-administration and find out the hard way? | An honest gap disclosed at the sales call costs nothing. The same gap discovered while a Certificate of Appointment is already 150 days overdue costs a lot more. | Every question in this checklist gets answered "yes, we handle that," with no specific limitation ever named. |
What a real vendor answer should look like — for DROZlegal specifically: there is no estates-specific module today, and no estates-specific deadline type such as the 180-day Estate Information Return clock. What does exist, inside the litigation module's form registry, is coverage of 54 Rule 74/75 estate forms, 10 of which (74.1A, 74.43, 74.45, 74A, 74B, 74D, 74E, 74F, 75.7, 75.12) are in the fully-generatable set, browsable at /litigation/forms. Platform-wide, every file benefits from Canadian data residency (AWS ca-central-1, encrypted in transit and at rest), AI processing under Anthropic's commercial API terms (inputs and outputs are never used to train models and are auto-deleted within roughly 30 days — not a zero-retention guarantee, since DROZlegal doesn't hold a separately negotiated zero-data-retention arrangement), conflict checking under Rule 3.4, and six hard ceilings — including any AI-initiated outbound email — that require a lawyer's sign-off before anything leaves the platform. That's the honest, specific shape of an answer to expect. A vendor that can't get this concrete about its own product isn't ready to answer it about yours.
Once you've worked through the checklist
Question 1 through 3's execution-validity questions are the ones worth double-checking against your own firm's current e-signature setup first — our companion post on AI wills and estates forms automation in Ontario covers what the litigation form registry does and doesn't reach for estates files specifically. If Group C's firm-readiness questions raised more than they answered, our 12-question internal readiness checklist is the upstream self-assessment to run before a vendor call at all. And once you have a shortlist, our free 32-item vendor due-diligence checklist scores a specific vendor across categories this post only opens. Evaluating AI vendors for a different practice area?
