Sole-practitioner and small law firms across Ontario, where the Law Society of Ontario's rules — not the purchase agreement — set most of the terms: only a licensee can hold an ownership interest, client files move only with client consent, and the trust account has to reconcile to zero before anything else closes.

Every figure below is a typical Canadian deal-market pattern, not a valuation — use it to sanity-check what you're being told.
| Metric | Typical benchmark | Use this to |
|---|---|---|
| Ownership is restricted by law, not by choice | Only a person licensed by the Law Society of Ontario may hold an ownership interest in a law practice — this rules out most outside or non-lawyer buyers before valuation even becomes the question.† | Confirm the buyer's own licensing status is the very first step, before comparing prices or terms. |
| Priced on billings and file inventory | Valued primarily on client billings history and the quality and stage of the file inventory being transferred, rather than on physical assets.† | Weigh the actual state of the file inventory — not just the historical revenue figure — when sizing up a practice. |
| Client consent sets the real transfer rate | Client consent is required before a file actually moves to a new lawyer, and the rate of consent — not the number of files listed — determines what genuinely transfers.† | Model realistic file-retention assumptions rather than treating the full file list as guaranteed business. |
| Trust account condition matters as much as the numbers | A trust account with a clean reconciliation history is treated as seriously as the financials themselves, given how directly it reflects on the practice's LSO standing.† | Treat trust-account cleanliness as a core diligence item, not a formality to confirm after price is agreed. |
| Area of practice affects transferability | Practices concentrated in relationship-driven areas, such as family or estates work, tend to see lower client-transfer rates than volume-driven areas, such as real estate or wills, with more standardized files.† | Adjust your expectations for client retention based on how relationship-dependent the practice area actually is. |
Only a person licensed by the Law Society of Ontario may hold an ownership interest in a law firm, which rules out most outside buyers and shapes the deal before price is even on the table.
Client files move to a new lawyer only with the client's consent — this is treated as a genuine transfer decision by the client, not a back-office administrative step in the sale.
The trust account has to be reconciled and wound up, or properly transferred, as part of any sale or succession — a step the Law Society treats with the same weight as the sale itself.
The same sequence underlies almost every law practice deal — what changes from deal to deal is how long each step takes, and which one becomes the bottleneck.
Reaching an agreement
The offer sets price and key terms — for a law practice it should build in the conditions that actually matter from day one, not just financing.
usually 1–2 weeks†The APS fixes price, structure — asset or share — and closing date, plus the reps, warranties, and holdbacks that protect you if diligence turns up something different than promised.
1–3 weeks to negotiate†LSO trust account wind-up, Client file transfer & consent, Conflicts screening, Succession/practice registration with LSO, Staff all start moving at once, on separate clocks — this is usually where law practice deals are won or lost.
often the critical path†Getting to closing
Corporate, PPSA lien, and litigation searches confirm what you're actually buying; we chase down licence standing and records the seller doesn't always have to hand.
2–4 weeks, in parallel†Funds, keys, and signed documents change hands, alongside any inventory count and interim authorizations that bridge the gap until final transfers are confirmed.
1 day, once conditions are met†We track final licence confirmation and the staff transition through to completion — nothing is left for you to chase once the deal is done.
1–2 week tail†This is the first real decision in almost every law practice deal — and it changes what you're buying, what you're taking on, and how it's taxed.
| Question | Asset purchase | Share purchase |
|---|---|---|
| What you buy | The practice's goodwill, client files (subject to consent), and its name — its assets, in other words. | Not generally available in this sector — most law firms aren't structured, or sold, as share transactions. |
| Client files | Transferred only with each client's consent, file by file. | Not applicable — practices in this sector are essentially never sold by share transaction. |
| Trust account | Wound up and reconciled to zero, or transferred under LSO's rules, as part of the sale. | Not applicable to the structure typically used in this sector. |
| Conflicts screening | Reviewed for the incoming lawyer before any file transfers. | Not applicable to the structure typically used in this sector. |
| Succession/practice registration | Notice to the Law Society of the change in the practice's registration. | Not applicable to the structure typically used in this sector. |
| Tax angle | Buyer gets a stepped-up cost base on the goodwill and assets purchased. | Not applicable to the structure typically used in this sector. |
| Typical use in a law practice deal | The standard, near-universal structure for a practice sale or succession in Ontario. | Essentially unused — ownership restrictions under LSO rules make this structure impractical here. |

A sole practitioner selling a stable, well-documented client base and files to another licensed lawyer.
Start my file →A multi-lawyer firm, a practice heavy in relationship-driven files with lower expected consent rates, or a sale bundled with a succession plan filed with the Law Society.
Book a consultation →Not sure which you are? That's our job to figure out, not yours. As a rough guide, most deals under a couple of million dollars are the first kind — above that, you're usually in Mergers & Acquisitions territory.
†Typical patterns across Canadian deals — not a quote or advice; every deal is confirmed on its own facts.
Only a person licensed by the Law Society of Ontario may hold an ownership interest in a law practice — this is a hard rule, not a negotiable term, and it rules out most outside buyers well before price becomes the question.
They generally don't move to the new lawyer — client consent is treated as a genuine decision, not an administrative formality. That's part of why file inventory gets modeled with a realistic transfer rate rather than treated as a guaranteed asset.
Because ownership restrictions under Law Society rules make a share sale impractical for most practices — the goodwill, files, and name are what's actually being sold, structured as an asset transaction rather than a corporate one.
It's reconciled and either wound up or properly transferred under the Law Society's own rules, treated with the same seriousness as the sale itself. This step doesn't get left until after the main agreement is signed.
It can affect which files transfer — if the incoming lawyer already represents an opposing party on a matter, that file is typically screened out of the transfer rather than the whole deal being derailed. The screen happens before file transfer, not as an afterthought.
