In the ever-evolving landscape of legal regulations, California Senate Bill 37 (SB 37) stands out as a pivotal update aimed at protecting consumers from misleading attorney advertisements. Signed into law in October 2025 and effective as of January 1, 2026, this legislation builds on existing rules to create a more transparent and accountable environment for legal marketing. For law firms operating in California, SB 37 introduces stricter guidelines that could reshape how you promote your services online and offline.
In this post, we’ll break down what SB 37 entails, its implications for your practice, practical steps to ensure compliance, and how SparkBlue Marketing can support your firm’s growth through ethical, high-impact digital strategies.
What Is SB 37?
SB 37, authored by Senator Thomas Umberg and chaptered as Chapter 645 of the Statutes of 2025, amends several sections of California’s Business and Professions Code (specifically Sections 6153, 6157, and 6157.2, while adding Section 6156.5). The bill’s primary focus is to curb unlawful solicitations and deceptive advertisements by attorneys, law firms, and referral services. It expands the definition of “advertisement” to include any communication, written, recorded, or electronic, that provides information about legal services to encourage potential clients to seek representation.
At its core, SB 37 enhances consumer protection by prohibiting false or misleading claims in legal ads. This includes bans on guarantees of success, implications of quick settlements, or the use of awards and recognitions that aren’t merit-based. The legislation also introduces robust enforcement mechanisms, allowing private citizens to pursue civil actions against violators, which could result in significant penalties.
While the bill doesn’t overhaul the entire legal advertising framework, it closes loopholes that previously allowed ambiguous or aggressive marketing tactics. It’s designed to foster trust in the legal profession by ensuring that all promotions are honest, verifiable, and clearly attributable to licensed professionals.
What SB 37 Means for Law Firms
For law firms in California, SB 37 represents both a challenge and an opportunity.
On the challenge side, the bill heightens scrutiny on marketing materials, particularly in digital spaces where ads can spread quickly. Non-compliance could lead to civil lawsuits, with potential damages ranging from $5,000 to $100,000 per violation (or three times actual damages, whichever is greater), plus attorney’s fees and injunctive relief.
Key impacts include:
- Increased Liability for Joint Advertising: If your firm participates in co-branded campaigns, each party must sign an agreement accepting responsibility for the content.
- Stricter Disclosure Requirements: Every ad must prominently feature the name of at least one California-licensed attorney, along with their firm’s bona fide office address.
- Prohibitions on Deceptive Elements: Firms can no longer use spokespersons without disclosing their titles, impersonate others without clear disclaimers, or make unsubstantiated claims about expertise.
- Enforcement Through Private Actions: Anyone, not just affected consumers, can initiate a lawsuit after notifying the advertiser and allowing a withdrawal period (72 hours for electronic ads, up to 30 days for print).
On the positive side, SB 37 levels the playing field by discouraging unethical competitors who rely on hype over substance. Compliant firms can build stronger client relationships based on transparency, potentially leading to higher retention and referrals.
How Law Firms Can Stay Compliant with SB 37
Compliance doesn’t have to be overwhelming. By integrating these best practices into your marketing workflow, you can mitigate risks while maintaining an effective presence:
- Review and Audit Existing Materials: Conduct a thorough audit of all ads, websites, social media profiles, and email campaigns. Ensure every piece includes the required attorney name and office address disclosures. Remove any prohibited language, such as guarantees of outcomes.
- Implement Clear Disclosure Policies: Make disclosures obvious; bold, large font, or prominent placement. For digital ads, use persistent banners or footers. In video or audio formats, include verbal disclaimers.
- Document Joint Advertising Agreements: For any collaborative marketing, draft and retain written agreements outlining shared liability. Consult with legal counsel to ensure these meet SB 37 standards.
- Train Your Team: Educate attorneys, marketers, and staff on the new rules. Regular training sessions can prevent accidental violations, especially in fast-paced digital environments.
- Leverage State Bar Resources: Before launching major campaigns, consider submitting materials for State Bar review if applicable. While not mandatory, this can provide a safe harbor against certain claims.
- Monitor and Respond to Complaints: Establish a process for handling withdrawal notices promptly. For electronic ads, aim to pull them within 72 hours; for other media, adhere to the 30-day window.
- Stay Updated on Amendments: Regulations evolve, so subscribe to updates from the State Bar of California or legal associations to catch any future changes.
By prioritizing these steps, your firm can avoid costly penalties and focus on what matters: delivering exceptional legal services.
