How to Comply With California’s New SB 478 “Hidden Fees” Law in Legal Services Advertising (2024)
California’s SB 478 “Hidden Fees” law took effect July 1, 2024, and it can apply to legal services advertising that states or implies a price. The statute targets “drip pricing” and requires that the price a consumer sees be the full, upfront amount—with only narrow exceptions. This article explains what SB 478 requires, how it intersects with California attorney advertising rules, and how to revise common law firm marketing materials to reduce risk.
SB 478 in plain English: what changed on July 1, 2024
California Senate Bill 478, commonly called the “Hidden Fees” law, prohibits advertising or offering a price to a consumer that is not the full price the consumer must pay to obtain the good or service. The primary target is “drip pricing”—marketing a low initial figure and then adding required charges later in the checkout, intake, or payment process.
For law firms, SB 478 matters because pricing claims are common in legal marketing: “$399 LLC formation,” “$0 down bankruptcy,” “DUI defense from $1,500,” “$99 consultation,” or “flat-fee eviction.” If the advertised number is not what most consumers can actually pay to obtain the service (because mandatory add-ons are required), the ad may create SB 478 exposure.
Where SB 478 lives in the codes
SB 478 is codified in California’s consumer protection framework (including provisions that treat hidden mandatory fees as unlawful). It is generally enforced through California’s unfair competition and false advertising regimes, which can support actions by public prosecutors and, in some contexts, private plaintiffs.
Important: SB 478 is not a State Bar rule. Even if an ad satisfies State Bar advertising standards, it can still be challenged under California consumer protection law if it uses unlawful pricing tactics.
Does SB 478 apply to attorneys and law firm advertising?
SB 478 is written broadly and applies to pricing offered to “consumers.” Many law firm clients—especially in criminal defense, immigration, family law, tenant/landlord disputes, consumer bankruptcy, and estate planning—are consumers in the ordinary sense. That means attorney marketing and intake practices can fall within the law’s practical reach when a firm offers or advertises prices to the public.
Some firms ask whether professional services are exempt. SB 478 is not drafted as a “retail only” statute, and the safer compliance posture is to assume it can apply to legal services marketing when the audience is the general public and the message functions as an offer or advertisement of price.
What SB 478 is trying to prevent
SB 478’s core concern is a price that is not actually available without paying additional mandatory amounts that were not included in the headline number. For legal services, that often appears as:
- Advertising a flat fee but excluding a required “file opening fee,” “technology fee,” or “administrative fee.”
- Advertising a “starting at” price that is rarely available and routinely requires mandatory “add-ons.”
- Advertising “$0 down” but requiring a mandatory enrollment or processing charge to begin representation.
- Advertising a “consultation” price but adding a required “document review fee” for every consult.
SB 478’s key rule: include the full price upfront
The compliance principle is straightforward: if you advertise a price, that price should be the total amount the consumer must pay to obtain the advertised service, excluding only limited categories that are legitimately optional or legitimately outside the seller’s control (depending on the context).
What “full price” means for legal services
In legal services, the “full price” question often turns on whether a charge is:
- Mandatory to receive the advertised service (must be included in the advertised price), or
- Optional (may be disclosed separately if truly optional), or
- Third-party/governmental (may require special handling—see below).
Because legal matters vary, firms often rely on ranges or “starting at” prices. SB 478 does not ban ranges or “starting at” language per se, but it increases risk if the ad suggests a consumer can obtain the service for the stated amount when, in reality, typical consumers must pay more due to required fees.
How SB 478 intersects with California attorney advertising rules
California attorneys must comply with the Rules of Professional Conduct governing communications about legal services, including prohibitions against false or misleading communications. Pricing claims are a classic source of advertising complaints because they can be misleading by omission.
SB 478 effectively raises the floor: it is not enough that a price statement is “not technically false.” If the consumer-facing price is missing mandatory components that will be added later, the pricing presentation can be unlawful even if the fine print eventually reveals the true total.
Why disclaimers may not cure drip pricing
Many marketers attempt to fix pricing ads with an asterisk and a footer: “*Fees may apply.” SB 478’s theory is that the headline price must be the real price. A disclaimer that additional mandatory charges will appear later is often the problem, not the cure.
Common law firm advertising scenarios (and compliant rewrites)
1) “Flat fee” packages that exclude mandatory charges
Noncompliant risk example: “Uncontested Divorce — $1,499 flat fee*” with a footer: “*Plus mandatory admin fee and client portal fee.”
Why it’s risky: If the admin/portal fees are required for every client who buys the package, the advertised price is not the full price.
Safer rewrite: “Uncontested Divorce — $1,649 total attorney fee (includes admin and client portal). Court costs extra.”
Notes: Government filing fees are often outside the firm’s control and may be stated separately, but be precise and avoid implying they are included if they are not.
2) “Starting at” prices that almost always increase due to required steps
Noncompliant risk example: “DUI Defense from $1,500” when nearly every case requires a mandatory $350 “DMV hearing handling fee.”
Safer rewrite options:
- “DUI Defense — from $1,850 total attorney fee (includes DMV hearing request/handling).”
- Or, if the DMV work is truly conditional: “DUI Defense — from $1,500 total attorney fee. If you request DMV hearing representation, add $350 (optional).”
The key is truthfully labeling a charge as optional only if a consumer can actually obtain the advertised service without it.
3) “$0 down” or “no money today” offers
Noncompliant risk example: “File Bankruptcy for $0 down” but intake requires a “mandatory $99 setup fee” before the firm begins work.
Safer rewrite: “Bankruptcy attorney fees available with $0 down (payment plan). $0 due at signing for qualified clients; if a setup fee applies, it must be included in the upfront advertised amount for that offer.”
If qualification criteria exist, state them clearly and ensure the offer is not illusory for most consumers.
4) Consultation pricing
Noncompliant risk example: “Consultation — $49” but every consult requires a separate mandatory “case evaluation fee” of $25.
Safer rewrite: “Consultation — $74 total (includes case evaluation).”
If you offer “free consultations,” ensure they are actually free for the typical consumer and not conditioned on required payments presented later.
5) Online checkout for fixed-fee services
Firms increasingly sell discrete services online (trademark searches, entity formations, demand letters). SB 478 risk increases when a checkout flow adds mandatory charges after the consumer commits time and information.
Compliance approach: display the total price on the first pricing screen and keep it consistent through checkout; if options exist (rush service, additional classes, extra respondents), present them as optional with clear pricing and unselected by default where appropriate.
Handling third-party charges: court filing fees, process servers, investigators, and translation
Legal matters often involve third-party costs. SB 478’s “full price” concept is easiest when the firm controls the charge. For third-party costs, treat compliance as a clarity exercise: separate what the firm charges from what others charge, and avoid using a single number that implies all-in pricing if it is not all-in.
Best practices for third-party costs
- Label clearly: “Attorney fee” vs. “court filing fee” vs. “service of process.”
- Use estimates carefully: If you provide an estimate of filing fees, date-stamp it and note that government fees can change.
- Avoid bait-and-switch: If a third-party cost is effectively always required (e.g., a filing fee in a standard petition), disclose it early and prominently.
Compliance checklist for California law firm marketing teams
Step 1: Inventory every place you mention price
Include: website landing pages, PPC ad copy, LSAs, meta titles/descriptions, intake scripts, email campaigns, fee sheets, SMS templates, chat widgets, and calendaring/booking pages.
Step 2: Identify “mandatory add-ons” that should be rolled into the price
Look for internal line items such as technology fees, admin fees, onboarding fees, payment plan fees, portal fees, “document management” fees, or “processing” fees. If the consumer must pay it to get the advertised service, it is a prime SB 478 concern.
