Legal Review of Marketing Materials: How Legal Teams Use AI

Marketing teams need to move campaigns forward. Legal review of marketing materials can slow that work when a lawyer has to find the study behind a claim, check a promotion's terms, or confirm that an image is cleared. The marketer needs a clear route to launch. The in-house lawyer needs enough context to make a defensible call. A first pass through legal AI can organize the campaign, compare claims with approved evidence, surface missing disclosures, and show which questions still need counsel.

Marketing gets specific changes to work through, and legal gets a cleaner review when the question calls for judgment.

That matters when a team is working across several channels, markets, and reviewers, and the final piece needs clear support for what it says.

Roughly one-third of GC AI users are not lawyers. They are in marketing, procurement, HR, and sales and are now handling initial legal questions before they reach counsel.

The time savings become clearer when the material is long and technical.

At an enterprise data-protection company that produces dozens of marketing pieces each week, some scripts run dozens of pages and, on one occasion, an entire book was part of the review queue.

The company's associate general counsel described the team's experience:

Material review can take anywhere from an hour to three hours because some of this stuff is extremely technical, at least in our universe. And sometimes their scripts are dozens of pages long... We've taken average review from one to three hours per piece down to, we can get it down to 30 minutes, 20 minutes, which is a massive savings for us. And when we're doing dozens and dozens of these a week.

Those are the AGC's own estimates. Treat them as an illustration of potential time savings.

The workflow started during the team's trial, when someone ran a piece of marketing copy through GC AI to see what it would catch. Material review became one of the team's regular uses for the platform.

Legal and marketing teams know how long this process can take. Marketing can produce more copy than legal can read in a week, while the company remains responsible for the claims it puts in front of customers.

GC AI is an enterprise legal AI platform purpose-built for in-house teams. It is trusted by 2,200+ legal teams including 300+ public companies. For marketing review, start with the standards counsel already applies and define which questions still need a lawyer.

What Legal Review of Marketing Materials Checks: Core Risks and Examples

Before a piece runs, ask whether the company can support every word, image, and claim in each market where it appears.

Use these seven checks as a starting point for U.S. advertising compliance review, then adjust them for the product, audience, market, and channel.

Express and Implied Claims

A statement about performance, price, results, or origin can create an objective claim that needs support before publication. FTC Act §5 prohibits unfair or deceptive practices, and the FTC's advertising substantiation policy describes the reasonable-basis requirement.

The review needs to consider images and context alongside the words. A recovery-time chart beside a data-protection product, for example, may suggest performance across environments even when the underlying test covered a narrower configuration.

Ask whether the evidence supports the claim the audience will take away. A technically accurate sentence can still contribute to a misleading overall impression.

Comparative and Superiority Claims

Claims such as “faster than” or “#1” raise questions about the comparison group, testing conditions, and how recently the company checked the result. Lanham Act §43(a) provides a basis for challenges to false or misleading representations in commercial advertising.

For example, a test against one competitor's older product may not support a broad claim about the current market. The review should connect the proposed wording to the specific comparison the evidence supports.

Endorsements, Testimonials, and Reviews

A testimonial needs review for both its claims and the relationship behind it. The FTC Endorsement Guides address truthful endorsements and disclosure of material connections that consumers would not reasonably expect.

The FTC Consumer Reviews Rule, effective October 21, 2024, separately addresses specified fake reviews, incentives conditioned on positive or negative sentiment, insider reviews, and review suppression. A gift-card campaign asking customers to leave reviews therefore needs a closer look at the invitation, incentive conditions, and disclosure.

An authentic customer quote does not establish that other customers will achieve the same result. Review the claim the campaign makes by placing that quote in context.

Disclosures and Disclaimers

A disclosure needs to reach the customer in a form they can notice and understand. The FTC's digital advertising disclosure guidance treats clarity and conspicuousness as contextual questions involving placement, prominence, and the device or format.

For a discounted subscription, review how the creative presents eligibility, duration, and the subsequent price. Qualifying language cannot repair a contradictory headline, and the material terms of the offer need to appear where the customer sees the offer.

Rights and Clearances

Review third-party marks, photography, music, and recognizable faces or voices against the permissions the company has on file. USPTO trademark basics and Copyright Office guidance are useful starting points, while counsel should assess publicity rights, license scope, and campaign-specific terms.

A licensed image may fall outside the permitted use when marketing moves it into a new campaign. AI-generated imagery also warrants a counsel-owned review for recognizable people, protected material, and applicable terms; generating an asset does not resolve those questions.

Product-Specific Rules

Health, financial, controlled-substance, alcohol, and children's marketing require analysis beyond a general advertising checklist. The product and intended audience should trigger the relevant specialist review, and these categories should remain research questions tied to the governing product and jurisdiction.

For health claims, the FTC's Health Products Compliance Guidance discusses the need for competent and reliable scientific evidence. A study can be legitimate while failing to support the advertised benefit, population, or conditions of use.

Financial promotions may raise product-specific disclosure questions, while a promotion involving a potentially controlled substance needs jurisdiction-specific analysis. For an unqualified U.S.-origin claim, the FTC's Made in USA guidance explains its “all or virtually all” standard.

Treat each example as a fact-dependent research trigger tied to the product and jurisdiction.

AI performance claims belong in the same review. The FTC's 2024 Operation AI Comply targeted deceptive claims about what AI products can do, so a deck promising a particular AI result needs support too.

State and Channel Requirements

The review needs the actual distribution plan. California Business and Professions Code §17500 addresses false or misleading advertising, while other states may add requirements relevant to the offer or product.

Email campaigns raise CAN-SPAM questions, and marketing texts can require analysis under the Telephone Consumer Protection Act and applicable state law. Sweepstakes and other promotions may also trigger eligibility, registration, or bonding requirements depending on their structure and jurisdictions.

Moving approved copy into a new channel can change the review. A disclosure that works on a landing page may disappear in a cropped social asset or a shortened message.

How to Use Legal AI for the First Pass on Marketing Review

The goal is a handoff counsel can use: the proposed claim, its supporting evidence, the unresolved issue, and a suggested edit. A request to check whether a campaign is compliant leaves too much work undefined.

Alexis Palmer, Senior Managing Counsel at Snyk, described how she uses a recurring prompt:

Whenever I get marketing material, I have a prompt I run and then tailor it down. And when we're brainstorming new product names, I'll run trademark searches across databases all at once, and GC AI will surface risks and suggestions I can share with the team.

Her approach combines repeatable instructions with room to adapt each review. Use Legal AI in five steps:

1. Assemble the campaign and reference materials
2. Save counsel's instructions as a skill
3. Run the draft against the evidence
4. Research the questions the file cannot answer
5. Return specific edits and route the decision

Assemble the Campaign and Reference Materials

Put substantiation studies, product specifications, advertising standards, and prior approved claims into a collection in GC AI’s Files. Files supports persistent document collections and sharing with teammates, so reviewers can work from the same references.

Keep the approval conditions with each claim. Record which product version, audience, market, and use the approval covers, along with any date or event that should trigger reconsideration.

For each review, supply the campaign brief and current creative, including relevant images and offer terms. A text draft alone cannot establish how a disclosure will appear in the finished asset.

Watch how this feature works:

Save Counsel's Instructions as a Skill

Use Skill Library to save the objective, intake questions, review sequence, and output format. Name a legal owner who can revise the instructions when company positions or requirements change.

GC AI's public Marketing Campaign Legal Review Skill example follows five stages:

• Extracting claims
• Checking claims and disclosures
• Reviewing third-party references
• Checking promotion terms
• Producing a recommendation

It also calls for exact copy references and minimum edits that preserve brand voice.

Before sharing the skill, run it against a completed campaign whose issues you already know. Check whether it catches the consequential problems and whether its proposed edits preserve the intended message.

Run the Draft Against the Evidence

Ask GC AI to apply the saved skill to the current campaign and its reference collection. Require it to distinguish a supported claim from a claim whose support is missing, outdated, or narrower than the wording.

Use Exact Quote to reference the precise language behind a flag and inspect the source document. For visual issues, ask for the asset and location, then review the image or layout directly.

Suppose an illustrative draft claims a product cuts recovery time by 50%, but the supplied study describes a particular test environment. A useful flag identifies the mismatch and asks the product owner whether broader evidence exists before suggesting a narrower claim.

Research the Questions the File Cannot Answer

Use Research for questions that require current law, such as whether a promotion needs different treatment in a named state. Research draws on primary law and authoritative sources and provides citations for review.

Give it the campaign date, jurisdictions, product details, and precise question. Ask it to distinguish legal requirements from company policy, identify exceptions, and flag missing facts that prevent a conclusion.

Counsel should check the cited authority and its application to the campaign. A state survey becomes useful when the reviewer can see which rule applies, why it applies, and what remains unresolved.

Watch the Research feature walkthrough:

Return Specific Edits and Route the Decision

Ask for a short issue table followed by a recommendation that explains the next action. Marketing needs the proposed wording, the reason for the change, and the person who can answer any outstanding factual question.

Keep the recommendation separate from the approval record. The company's review rules determine who can clear the piece and whether an exception requires counsel.

The following illustrative prompt adapts the public Skill structure for a first-pass review:

Objective: Prepare a first-pass legal review of the attached marketing campaign for the company's designated reviewer.

Inputs: Use the campaign brief, current creative, and reference collection in Files. Identify the version reviewed.

Intake: Extract the markets, channels, audience, product, campaign dates, third-party references, and promotion terms from the materials. Ask for missing information that could change the review.

Workflow:

1. Identify claims: List express and implied factual claims. Distinguish supported claims, possible puffery, and claims needing further evidence. Explain any assumption about what the audience would understand.

2. Check support and disclosures: Compare the claims with the supplied evidence and advertising standards. Flag gaps, qualifications, and disclosure issues.

3. Review third-party references: Identify trademark, copyright, and likeness questions. Check supplied permissions and flag their limits.

4. Check promotions: Compare the advertised offer with its terms and disclosures. Flag jurisdiction or channel questions for current legal research.

5. Prepare the handoff: Return a table with Item, Risk Level (High, Medium, Low), and Recommended Edit. Finish with a two-sentence recommendation and identify unresolved questions and their owners.

Rules: Quote the exact copy behind each textual flag and cite the relevant reference section. Identify visual issues by asset and location. Preserve brand voice and propose the smallest useful edit. Separate legal requirements, company policy, and missing evidence. Do not invent support or treat the recommendation as approval.

After the first run, review whether the output distinguishes substantive issues from preferences. If it repeatedly treats an approved stylistic choice as a legal problem, refine the instructions before asking marketing to use them.

What Stays With the Lawyer in Advertising Compliance Review

Counsel still assesses whether the substantiation is adequate, how the law applies to the facts, and which legally permissible risks the business can accept. AI can organize evidence and propose changes, but an AI flag list does not approve a marketing piece.

The lawyer also decides how to communicate the result. Marketing may need a narrower claim, an additional qualification, or a question for the product team rather than a lengthy explanation of every conceivable objection.

That judgment includes reading the complete piece when its context matters. A sentence-level review can miss an implication created by the headline, photograph, testimonial, and purchase flow together.

Review the final version at the level its risk requires, and record the conditions of clearance. If marketing changes the claim, audience, offer, or presentation afterward, the team needs a clear rule for reopening review.

How to Tier Marketing Review and Hand Off Routine Work

Written tiers give marketing a predictable route and give legal a way to concentrate review on new claims and exceptions.

The table below is a starting model for counsel to adapt to the company's products and risk tolerance.

Tier	What Belongs Here	Who Clears It
Routine	Current approved templates and claims used within their documented product, market, audience, and channel conditions	A designated marketing owner may clear the piece under counsel-approved rules after the first pass and required checks; exceptions and unresolved flags go to legal
Standard	New copy using approved claims in a familiar market and channel, without elevated-risk features	Counsel reviews the first-pass findings and relevant creative before clearance
Elevated	New or comparative claims, testimonials or creator content, regulated products, sensitive audiences, new jurisdictions, or material uncertainty	Counsel reviews the complete piece and supporting evidence, involving specialists as needed

A familiar claim can move into a higher tier when the context changes. For example, marketing might reuse approved product language beside a new customer testimonial that implies a broader result.

For routine work, share the legal-owned skill and the appropriate reference collection with the marketers preparing the copy. Their handoff should identify the asset version, applicable approval, first-pass findings, and any changes they made.

Define escalation triggers in language the team can apply. Missing evidence, an expired permission, a new jurisdiction, or uncertainty about a tier should have a named legal contact and an agreed route for review.

Compliance monitoring tools can scan assets against configured rules and keep an audit trail. A legal AI platform can handle the elevated questions around substantiation, creator agreements, and state law. AI for Compliance Monitoring explains how the monitoring layer fits with legal review.

Teams should apply their own information-security review before adding campaign materials. GC AI's data security guidance covers SOC 2 Type II and SOC 3, GDPR, AES-256 encryption at rest, TLS 1.2+ in transit, data segregation, provider no-training commitments, and zero-data-retention agreements with LLM providers wherever feasible; the subprocessor list is public.

Rachel Harris, General Counsel and AI Governance and Privacy Officer at Suzy, discussed the handoff on CZ and Friends. GC AI CEO Cecilia Ziniti hosts the podcast and interviews legal leaders. Harris said:

The real question becomes, have we not integrated ourselves into this workflow appropriately, to where once it gets to us, it feels like a bottleneck?

For marketing review, that means giving the team useful instructions while it is drafting. Counsel-approved claims, accessible supporting documents, and clear escalation rules help the marketer resolve routine questions before asking legal to review the campaign.

Legal should periodically sample routine clearances and use the findings to update the skill and tier rules. Repeated exceptions can show that the instructions need work or that a category deserves more direct review.

Start With One Recurring Marketing Review

Choose a recurring campaign type and build its first pass in GC AI using the references your team already trusts. Have counsel run the initial reviews, adjust the skill, and then decide whether marketing can take responsibility for defined parts of the process.

Measure total review time through clearance, including preparation, verification, and revisions. Compare similar pieces and record material issues caught or missed, so a faster first response does not obscure additional work later.

Time recovered gives the team capacity for other matters. A cost claim needs a separate calculation showing whether that capacity reduced outside counsel spend, overtime, or another expense. Use the pilot to agree on the handoff: which pieces of marketing can clear under counsel-approved rules, which need legal review, and what evidence travels with each submission.

Then expand the workflow to the next recurring campaign.
