Understanding the Legal Risks of Influencer Marketing

Understanding the legal risks influencer marketing presents is essential, as campaigns are more complex than many brands realise. What looks like a straightforward partnership between a brand and a creator can quickly become a legal minefield if the proper safeguards aren't in place.

At DG Digital Marketing, we help brands navigate these challenges by understanding the key areas where campaigns go wrong. The risks span advertising disclosure rules, contract gaps, copyright issues, and data protection compliance. Each one can expose your brand to significant penalties, reputational damage, or both.

The stakes are higher than ever. Regulators across the UK and Europe are tightening enforcement. Influencers themselves face legal pressure. And consumers are increasingly sceptical of undisclosed partnerships. Getting this right isn't optional, it's essential to protecting your brand.

ASA Influencer Advertising Disclosure Rules

The Advertising Standards Authority (ASA) has clear rules about how influencers must disclose paid partnerships. These rules exist to protect consumers from misleading advertising.

Any content created in exchange for payment, free products, or other benefits must be clearly labelled as advertising. The disclosure needs to be upfront and obvious, buried in a caption or hidden in a hashtag doesn't count.

Common disclosure methods include:

• #ad or #sponsored at the start of a caption
• "Paid partnership" labels (available on Instagram)
• Clear statements like "This is a sponsored post"
• Prominent disclaimers on video content

The key principle: a typical consumer should understand immediately that the post is advertising. If they have to hunt for the disclosure, it's not compliant.

Many brands assume their influencers know these rules. They don't always. You need to brief every creator explicitly on disclosure requirements before content goes live. The ASA holds both the brand and the influencer accountable, so your responsibility doesn't end when you hand over the brief.

Influencer Marketing Contract Clauses You Need

A contract addressing the legal risks influencer marketing creates protects both parties. Without one, you're relying on goodwill and memory, both unreliable when disputes arise.

Your influencer marketing contract should cover:

• Deliverables: Exactly what content will be created, how many posts, which platforms, posting dates
• Usage rights: How long the brand can use the content, whether it can be repurposed, whether the influencer can delete it later
• Disclosure obligations: Explicit requirement to disclose the partnership according to ASA rules
• Performance metrics: What constitutes acceptable engagement, posting quality, and audience authenticity
• Payment terms: Exact amount, payment schedule, what triggers payment (posting date vs. performance targets)
• Exclusivity clauses: Whether the influencer can promote competing brands during the campaign period
• Liability and indemnification: Who's responsible if the content breaches copyright, defames someone, or violates regulations
• Termination rights: Under what circumstances either party can exit the agreement

Without these clauses, you're exposed. An influencer might delete content after being paid. They might fail to disclose the partnership. They might post something that damages your brand. A solid contract gives you recourse.

Treat influencer agreements like any other commercial contract, detailed, specific, and legally reviewed before signing.

Influencer Marketing Copyright and Usage Rights

Copyright issues cause more disputes than any other legal problem in influencer campaigns.

The creator owns the copyright to content they produce unless the contract explicitly states otherwise. This means you can't reuse their photos, videos, or written content without permission, even if you paid for it.

Many brands make this mistake: they assume purchasing a post gives them unlimited usage rights. It doesn't. By default, the influencer retains ownership.

Your contract needs to specify:

• Whether the brand owns the content outright or has a licence to use it
• How long the brand can use the content (perpetual vs. time-limited)
• Where the content can be used (Instagram only, or across all marketing channels)
• Whether the influencer can be tagged or credited when the brand repurposes content
• What happens to the content after the campaign ends

If you want to use an influencer's content in paid advertising, your own website, or future campaigns, you must negotiate this explicitly. The cost of licensing content varies, some influencers charge extra, others include it in their fee.

The reverse also matters: influencers must not use copyrighted music, images, or other protected material without permission. If they do, you're both liable. Review content before it goes live.

Liability and Misleading Claims

Influencers make claims about products. Those claims must be truthful and substantiated.

If an influencer says a skincare product "removes wrinkles" or a supplement "cures fatigue," those are advertising claims. They need evidence. The brand is responsible for ensuring claims are accurate, you can't hide behind the influencer's words.

This applies to:

• Health and wellness claims (especially high-risk categories like medical devices, treatments, supplements)
• Performance claims ("increases sales by 40%", "saves 5 hours per week")
• Comparative claims ("better than the leading brand")
• Testimonial claims ("this changed my life")

The ASA and Trading Standards can investigate misleading advertising. Penalties include:

• Ads being withdrawn or banned
• Corrective advertising requirements
• Fines and enforcement action
• Reputational damage

Before an influencer posts, review the script or content. If claims seem exaggerated, push back. Ask for evidence. Require disclaimers where appropriate ("individual results may vary").

Your legal team should audit high-risk categories (health, finance, legal services) before content goes live.

Data Protection and Privacy Compliance

Influencer campaigns involve collecting and using personal data. GDPR and UK data protection law apply.

Common compliance issues:

• Email lists: If you're buying or receiving influencer email lists, you need explicit consent from each person on that list. Purchasing a list without consent breaches GDPR.
• Affiliate tracking: Affiliate links and discount codes track customer behaviour. You need privacy notices explaining how data is collected and used.
• Audience insights: Analysing influencer audience data to target ads requires transparency and legal basis.
• Influencer payments: Paying influencers creates a data processing relationship. You need a data processing agreement (DPA) in place.

Your contract with influencers should include:

• A clause confirming they'll comply with data protection law
• Clear instructions on what personal data they can collect and how
• A DPA if you're processing their data (payment details, performance metrics, etc.)

If you're collecting customer data through an influencer campaign (email signups, surveys, etc.), you need:

• A privacy notice explaining data use
• Explicit opt-in consent
• Secure data storage
• A process for honouring data subject rights (access, deletion, etc.)

Data breaches or non-compliance can result in ICO fines up to £17.5 million or 4% of global turnover, whichever is higher.
