# LSO Marketing Rules and Your Website

## Key facts

| Fact | Value |
|---|---|
| Core standard | Marketing must be demonstrably true, accurate and verifiable — Rule 4.2-1 |
| "Specialist" | Only for lawyers the Law Society has certified — Rule 4.3-1. "Expert" is not named in the Rules but can imply it |
| Testimonials | Not banned. They must meet Rule 4.2-1, and the commentary flags testimonials that contain emotional appeals |
| Fee advertising | Must be precise about what's covered and state what's extra — Rule 4.2-2 |
| Identification | Marketing must state the person is licensed as a lawyer — Rule 4.2-1.1 |

**A law firm website is marketing under Chapter 4 of the Law Society of Ontario's Rules of Professional Conduct, so every page must be demonstrably true, accurate and verifiable and not misleading (rule 4.2-1). On top of that standard: no "specialist" unless the Law Society has certified you (rule 4.3-1), amounts recovered only with the past-results statement, testimonials only where they are true and carry no emotional appeal, fees stated precisely with extras named (rule 4.2-2), and every page identifying you as a lawyer (rule 4.2-1.1).** Get these wrong on a website and the fix usually touches every page, not just one.

This is general information, not legal advice: check the current Rules and commentary before you publish, and have a licensee review your final copy.

## Which LSO rules apply to a law firm website?

Chapter 4 of the Rules of Professional Conduct governs "Marketing" and applies to a law firm's website the same way it applies to a print ad or a business card — a website is marketing. The rule most website copy runs into is Rule 4.2-1: a lawyer may market legal services only if the marketing is "demonstrably true, accurate and verifiable", is "neither misleading, confusing, or deceptive, nor likely to mislead, confuse or deceive", and is "in the best interests of the public and is consistent with a high standard of professionalism". Related provisions cover fee advertising and, under Rule 4.2-1.1, a requirement to "specifically identify in all marketing materials" that the person is licensed as a lawyer, which distinguishes them from a paralegal with a narrower scope of practice.

This applies to every surface a firm controls, not just the homepage: practice-area pages, lawyer bios, blog guides, the firm's Google Business Profile description, and social media posts that link back to the site. A firm that gets its website copy right but leaves an old "Best Lawyer 2019" claim on a LinkedIn banner hasn't actually fixed the underlying problem — the rules follow the claim, not the page format.

## Can a law firm website say "specialist" or "expert"?

"Specialist" is not a marketing adjective under the LSO's rules; it is a credential. Rule 4.3-1: a lawyer "shall not advertise that the lawyer is a specialist in a specified field unless the lawyer has been so certified by the Law Society", and the certification is granted field by field. "Expert" is not named in the Rules, but the commentary bars any designation from which a person might reasonably conclude the lawyer is a certified specialist. That rules out phrasing like "specializing in real estate law" without the certification, and makes "our family law expert" a risk worth avoiding. The safe, accurate alternative is describing practice focus in plain terms: "practises primarily in family law," "concentrates on residential real estate transactions." It reads just as confidently and doesn't create a compliance problem.

The same logic extends to awards, rankings and third-party badges: they should only appear if they're bona fide and not likely to mislead a reader about what they represent. A "Top Lawyer" badge from a pay-to-play directory is the kind of claim this rule exists to catch.

A related, easy-to-miss trap is inconsistency between the website and other public-facing materials — a bio that lists a bona fide credential on the site but overstates it on a directory listing, or a fee statement on the website that doesn't match what a client is actually billed. The demonstrably-true-and-verifiable standard isn't limited to the words on the page; it extends to whether the firm's actual practice matches what the page claims.

## Can a law firm website show testimonials and reviews?

Client testimonials are not banned. Like all marketing they must be demonstrably true, accurate and verifiable and not misleading (Rule 4.2-1), and the commentary to that rule lists "using testimonials or endorsements which contain emotional appeals" among the examples of marketing that may breach it. Those conditions are enough that many Ontario firms choose not to run testimonials at all. Before publishing one, we would also get the client's written permission: naming someone as a client is itself a disclosure. A testimonial that implies a typical outcome, states a settlement figure without context, or reads as a paid endorsement crosses the line. Star-rating strips and lifted Google reviews sit in the same category as testimonials for compliance purposes — treat them with the same care rather than assuming a third-party platform makes the content safe to reproduce.

## How should a law firm website state its fees?

You're allowed to advertise fees, including a fixed fee for a defined service or a contingency arrangement for eligible matters, but the advertising has to be precise about exactly what's covered by the quoted fee and has to state clearly what costs are additional — disbursements, taxes, or third-party charges. "Wills starting at $400" without qualifying what's included invites the kind of scrutiny that "a straightforward single will, disbursements extra" doesn't. Once you advertise a fee, Rule 4.2-2(c) requires that you "strictly adhere" to it in every applicable case.

## What identification and disclaimers does a law firm website need?

Every page of marketing should make clear that the person or firm is licensed to practise law in Ontario — a simple footer line naming the firm and its LSO status covers this on a website. Two more things are good practice for legal content, though the Rules do not require them: a disclaimer on any guide or FAQ stating that the content is general information, doesn't create a solicitor-client relationship, and isn't advice for the reader's specific situation; and a privacy statement covering how intake-form data is handled before a retainer exists. On the Tokas Lex build this lives on a dedicated legal notices page, linked from the footer of every practice-area page and guide.

A practical way to run this as an ongoing process, rather than a one-time review: treat the compliance pass the same way you treat a proofread. Every new guide or updated bio gets checked against the same short list — no unverified superlative, no uncertified "specialist" language, testimonial rules respected, fee language precise, disclaimer present — before it publishes, not after a client or a Law Society complaint flags it.

Keep records of how you arrived at a claim, too — the awards you list, the years-of-experience figures, the "since 19XX" line in the footer. If the Law Society ever asks a firm to substantiate a marketing claim, "we're pretty sure that's right" is a worse answer than being able to point to the source.

## FAQ

### Can I call myself a specialist?
Only if the Law Society of Ontario has certified you as a specialist in that field (Rule 4.3-1). "Expert" is not a word the Rules name, but the commentary to Rule 4.3-1 bars any designation from which a reader might reasonably conclude you are a certified specialist, and the commentary to Rule 4.2-1 lists suggesting qualitative superiority to other lawyers as marketing that may breach the rule, so treat "expert" with the same care. Describing your practice as "focused on family law" or "concentrated in real estate" is fine; "specialist in family law" without the certification is not.

### Can I display Google reviews?
Third-party review platforms sit in a greyer area than testimonials you collect and publish yourself, and the safest approach is to treat any published review the same way as a testimonial: it must be genuine, not solicited in exchange for anything, and not cherry-picked to imply a typical result you can't support. When in doubt, link to your Google Business Profile rather than reproducing star ratings and quotes on the page itself.

### Do I need a "not legal advice" disclaimer?
The Rules do not require one: Chapter 4 never mentions a disclaimer. It is still strongly advisable on any page that explains a legal process or answers a legal question in plain language — a guide, an FAQ, a practice-area page. It should state plainly that the content is general information, doesn't create a solicitor-client relationship, and isn't a substitute for advice on the reader's specific situation.
