Why a family file isn't a commercial file, for AI purposes
Most AI vendor checklists were written for contract review or commercial litigation — files where the only people involved signed something first. Family law doesn't work that way. Statistics Canada's March 26, 2026 Daily release on family law cases in civil courts counted 278,503 active family law cases in 2024/2025 across the six provinces and three territories that report to the Civil Court Survey, about 30% of the country's active civil caseload. More than a quarter (27%) of those cases carried a financial-support issue, and 81% of the cases with a support issue were still ongoing from a previous fiscal year — meaning the financial disclosure an AI tool might touch often spans several years and several rounds of updates, not one intake.
Legal-representation data from the same release (reported only in Prince Edward Island, Nova Scotia, New Brunswick, and Ontario) found that in nearly two-thirds (65%) of active 2024/2025 family law cases, at least one respondent was self-represented at some point and no respondent in that case ever had legal representation. A tool your firm buys may end up producing documents a self-represented opposing party reads directly — and a child, a new partner, or a grandparent named in a parenting or support dispute is a fixture of the file, not an edge case. None of that shows up if you evaluate an AI vendor the same way a corporate or real-estate practice would. The ten questions below are the ones that do.
Group A — Confidentiality and data handling
Family files are unusual in how many non-client people's information passes through them. Start here before pricing or features.
| # | Question | Why it matters | Red flag answer |
|---|---|---|---|
| 1 | Does the vendor's privacy language even mention data about people who aren't your client — children, new partners, other relatives named in a parenting or support dispute? | A tool built for commercial-contract review was never designed around third-party or minors' data appearing in the file by default. Information a child shares that's routed through the Office of the Children's Lawyer, for example, has its own confidentiality treatment separate from your client's — the courts have held OCL client records exempt from freedom-of-information requests entirely (Ontario (Children's Lawyer) v. Ontario (IPC), 2018 ONCA 559). | The privacy policy talks only about "your firm's data" and "your client," with no line for third parties or minors. |
| 2 | Is your firm's data used to train the vendor's underlying model, and can they name an exact retention window in writing? | "We don't know exactly how the program is going to use that information in future" is how one Canadian family lawyer put the risk to Canadian Lawyer — a fair worry with an open-source or general-purpose model, less so with a vendor that states its training-use and retention policy in specific, checkable terms. | "We take privacy seriously," with no specific training-use answer or retention number. |
| 3 | Where is the data physically stored, and does the answer match the vendor's actual subprocessor list — not just its marketing page? | PIPEDA- and FIPPA-aware firms need a named region, not a description. If the answer is "secure cloud infrastructure" with no country or region named, that's not an answer. | No named data-residency region anywhere in the vendor's docs, only in a sales call. |
Group B — Fit with the rules that actually govern a family file
General AI-ethics guidance is a floor. Family practice has its own specific requirements on top of it.
| # | Question | Why it matters | Red flag answer |
|---|---|---|---|
| 4 | Can the tool preserve or produce a public hyperlink for every AI-touched case citation, the way the family court actually requires? | Section K of the Superior Court's Consolidated Provincial Practice Direction for Family Proceedings (current version dated March 17, 2026) asks for independent verification and a public hyperlink to the authority — see our full breakdown of the rule. A tool that "cites sources" internally but gives you nothing you can hand to a judge doesn't close that duty. | "We cite our sources" with no mention of a filing-ready, publicly accessible link. |
| 5 | If your firm runs domestic contracts — separation agreements, marriage contracts — through the tool, does its e-signature flow actually capture an independent witness? | Under the Family Law Act, a domestic contract generally isn't enforceable unless it's in writing, signed, and witnessed by an independent adult third party who watches both parties sign. A generic e-sign flow built for a commercial service agreement doesn't necessarily capture that step at all. | "We support e-signatures," with witnessing never mentioned. |
| 6 | Does conflict-checking search every party on a related file — not just the "client" field? | Family firms see the same names recur across a spouse's file, a new partner's file, and a related parenting dispute far more than most practice areas. A conflict check that only searches by client name misses exactly the pattern family practices need caught. | Conflict search returns nothing unless the exact client name is typed in. |
Group C — Whether it fits a family practice day to day
| # | Question | Why it matters | Red flag answer |
|---|---|---|---|
| 7 | Is there a named human sign-off before anything AI-assisted reaches a client, opposing counsel, or the court? | Custody and support disputes carry higher emotional stakes than most commercial files a mistaken send affects. A named reviewer, not "whoever has time," is the difference between a caught error and a filed one. | "The system flags things for review," with no person actually named as responsible. |
| 8 | If the vendor shut down or was acquired tomorrow, could you export every file in a usable format — and on what timeline? | Family files often run for years across custody variations and support enforcement, so vendor durability matters more here than in a one-off transactional practice. Our writeup of a UK legal-AI vendor's 2025–2026 collapse is the cautionary version of this question. | Export is "available on request," with no stated format or turnaround. |
| 9 | Is the pricing actually built for a practice your size — solo or 2–5-lawyer family firms are the norm, not the exception? | Our adoption-economics breakdown for 1–5-lawyer firms covers why per-seat enterprise pricing built for a 40-lawyer litigation shop doesn't translate cleanly to a family practice's caseload and margins. | Pricing is quoted only in enterprise tiers, with no answer for a two-lawyer firm. |
| 10 | Will the vendor tell you plainly what the tool does not do yet for family files — before you're mid-file and find out the hard way? | An honest gap disclosed up front costs you nothing. A gap discovered during a custody hearing costs a lot more. | Every question gets a version of "yes, we handle that," with no named limitation anywhere. |
What a real vendor answer should look like — for DROZlegal specifically: there is no family-law-specific module today. What does exist, platform-wide, is 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 court filing and 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 for its own product isn't ready to answer it for yours.
Once you've worked through the checklist
Question 4 gets a full treatment in our companion post on Ontario's family-court AI citation-verification rule. If confidentiality and firm-readiness questions in Group A raised more questions than they answered, our 12-question internal readiness checklist is the upstream self-assessment to run before you're in front of a vendor at all. And once you have a shortlist, our free 32-item vendor due-diligence checklist scores a specific vendor across the categories this post only opens.
