The verdict in three sentences
For a 12-person notary office in Montréal, custom notarial software costs between CAD 25,000 and 60,000, compared with CAD 12,000 to 30,000 to deploy an off-the-shelf suite, plus annual per-user licences. Off-the-shelf suites cover standard Québec deeds well, but offices with specialised practices (commercial real estate, estates, corporate) end up running parallel spreadsheets. Custom wins once the office wants reliable trust accounting, secure digital archiving and demonstrable compliance with Québec's Law 25 on personal information.
Both options, costed
An office still working in Word and Excel loses time at every step: finding an old deed, calculating fees, reconciling funds held in trust for clients. The choice of tool determines the security of client funds, which is a notary's top disciplinary risk with the Chambre des notaires.
| Criterion | Off-the-shelf suite (2026 estimate) | Custom software |
|---|---|---|
| Initial cost | CAD 12,000 to 30,000 | CAD 25,000 to 60,000 |
| Annual licences | CAD 3,000 to 8,000 | CAD 0, maintenance CAD 3,000 to 6,000 a year |
| Specialised deed templates | Generic, customisation billed extra | Modelled from the start |
| Fee and duty calculation | Standard tables | Office-specific rules built in |
| Trust accounting | Standard module | Reconciliation per file and per client |
| Data hosting | Vendor cloud, location varies | Canada, documented for Law 25 |
| Go-live time | 2 to 4 months | 4 to 6 months |
Over five years, a suite at CAD 20,000 plus CAD 6,000 a year in licences costs CAD 50,000, before customisation. A custom build at CAD 40,000 plus CAD 4,000 of annual maintenance costs CAD 60,000, without vendor lock-in and with a tool shaped around the office's real practice.
Essential modules and their budget
| Module | Indicative 2026 budget | Concrete benefit |
|---|---|---|
| File and deed management (templates, versions) | CAD 6,000 to 14,000 | Standard deed drafted in 30 min instead of 2 h |
| Fee, duty and welcome tax calculation | CAD 3,000 to 6,000 | Provisioning errors almost eliminated |
| Trust accounting and bank reconciliation | CAD 6,000 to 12,000 | Per-client balance in real time |
| Registration tracking (land registry) | CAD 3,000 to 7,000 | Registration delays tracked per file |
| Secure digital archive and full-text search | CAD 4,000 to 10,000 | A 2010 deed found in 10 seconds |
| Client portal (file tracking, online payment) | CAD 2,000 to 6,000 | 40% fewer status calls |
Law 25 requires a designated person responsible for personal information, privacy impact assessments for new systems and incident reporting to the Commission d'accès à l'information. For a notary office, identity, assets and family data are sensitive. The software must include encryption, role-based access (notary, paralegal, accountant), logging of every access and documented retention periods. Budget CAD 1,000 to 3,000 for the privacy impact assessment.
Mini case study
Me Tremblay, senior notary at a 12-person office in Old Montréal, handles about 70 deeds a month. Paralegals spend an average of 1.5 hours per deed on templates, calculations and re-typing.
With custom software quoted at CAD 44,000, time drops to about 45 minutes per deed. Saving: 45 minutes x 70 deeds = 52 hours a month, or 630 hours a year. At CAD 45 an hour (loaded paralegal cost), that is CAD 28,350 a year. Add the end of a part-time archiving role (CAD 18,000 a year) and saved licences (CAD 5,000 a year).
Total gain: about CAD 51,000 a year. The investment pays for itself in roughly 10 months, with trust accounting that can be audited at any time.

FAQ
Can an off-the-shelf notarial suite be used as is?
For a general practice, often yes. Offices with specialised work usually spend CAD 4,000 to 10,000 on customisation or keep side spreadsheets, which is where custom software becomes the better long-term option.
How long does the project take?
Allow 4 to 6 months: 1 month of scoping with notaries and paralegals, 3 to 4 months of modular development, then 1 month of deed migration and training. Scanning paper archives is planned separately.
Where should the office's data be hosted?
In Canada, with daily encrypted backups and a documented Law 25 assessment. Secure hosting costs CAD 150 to 450 a month for a 12-person office.
Can clients pay deposits online?
Yes. The client portal can accept card, Interac e-Transfer or wire, with each payment automatically allocated to the right file in trust accounting. Card processing fees are around 2.9% per transaction.
What happens to our Word and Excel history?
It is imported and indexed: Word deeds become searchable in full text and linked to their files. For 10 years of history, migration usually accounts for CAD 2,000 to 6,000 of the budget.
