Most businesses launch their affiliate program with a quick copy-paste from someone else’s terms page, a shrug, and a “we’ll fix it later.” Later never comes. And then comes the fraud, the disputes, the trademark bidding, or the FTC complaint. Writing a solid affiliate program agreement doesn’t require a lawyer. It requires knowing what actually goes in one.
Why you need an affiliate program agreement before you launch
An affiliate program agreement is a legal contract between you and every affiliate who joins your program. It defines what they can and can’t do, how they get paid, what happens when they break the rules, and how disputes get handled. Without one, you have no legal standing to remove a bad actor, claw back fraudulent commissions, or enforce any promotion restrictions at all.
I’ve run affiliate programs for companies like Tony Robbins, Michael Hyatt, Shutterfly, and Adidas. The programs that ran cleanly had airtight terms. The ones that didn’t? I watched managers spend weeks chasing coupon affiliates who were cannibalizing organic traffic, dealing with affiliates bidding on trademarked keywords, or untangling commission disputes that had no documented answer. None of that is fun. Most of it is avoidable.
The other thing worth knowing: you don’t need to pay a lawyer thousands of dollars to write this document. You need to understand the required sections, know which optional clauses apply to your situation, and start with a proven template. The Affiliate Terms Wizard was built for exactly this, trained on 1,000+ attorney-written agreements and designed to walk you through the process in under 15 minutes for $49. But even if you go another route, here’s exactly what needs to be in your agreement.
The required sections every agreement must include
These aren’t optional. Every affiliate program, regardless of size, niche, or commission structure, needs all of these.
Preamble. A short opening paragraph that sets the tone and confirms affiliates have read and agreed to the terms before promoting. Keep it plain. Shutterfly’s preamble is a good model: it states the document is written in plain language intentionally, and that each affiliate is responsible for making sure their own employees and contractors comply. Nothing fancy, just a clear agreement that everyone is bound by what follows.
Definitions. Define the key terms so there’s no ambiguity later. “We,” “you,” “the program,” “the website.” Michael Hyatt’s agreement does this cleanly in five short definitions. It’s boilerplate, but it closes the door on disputes where someone claims they didn’t understand what “affiliate” meant in the context of the agreement.
Approval and rejection policy. This spells out your process for accepting or declining applicants and protects you if a rejected affiliate complains. A standard version: applications are reviewed within 48 business hours, you reserve the right to reject any application, and you encourage applicants to contact you if they believe an error was made. The last part is important. It signals good faith and gives you a chance to correct mistakes before a rejected affiliate goes public with a complaint.
Commission structure and payment terms. How much you pay, when you pay it, what the minimum payment threshold is, and what payment methods you use. This is also where you define what happens when multiple affiliates get credit for a single click, whether you use first-click or last-click attribution, and how long the cookie lasts. Get specific. Vague commission language is the number one source of affiliate disputes.
Reversal policy. Define the circumstances under which you’ll reverse a commission: order cancellations, returns, duplicate tracking, disputed charges, or program violations. Tiny Prints used this language, which I’ve adapted for dozens of clients: “We reserve the right to reverse orders due to order cancellations, duplicate tracking, returns, disputed charges, and program violations as outlined in these terms.” Also include what you expect from affiliates if you flag suspicious transactions. If they can’t substantiate traffic sources or don’t respond within a reasonable time, you reserve the right to reverse the relevant orders and set their commission to zero. This clause protects you during fraud investigations without requiring you to prove intent.
FTC disclosure requirements. The FTC requires affiliates to disclose their relationship with your business whenever they promote your products. Your agreement needs to spell this out explicitly: disclosures must appear on every page or post containing affiliate links, they must be placed above the fold, pop-up disclosures are not allowed, and non-US affiliates still have to comply with US FTC rules. I know this from personal experience. I’ve been on the wrong side of an FTC investigation and it is NOT fun. By including FTC requirements in your agreement, you establish that affiliates were informed and agreed to comply. It won’t eliminate your liability entirely, but it matters a lot if something goes wrong. Pair this with the FTC disclosure post to make sure your affiliates actually know what compliance looks like in practice.
Termination clause. You need the right to terminate an affiliate at any time, for any reason, with or without notice. You should also define what happens to pending commissions when an account is terminated for cause. Generally, program violations forfeit any unpaid earnings. Make this explicit.
Website restrictions and promotion guidelines
Website restrictions define what kinds of sites can participate in your program. You want to prohibit affiliates from promoting on sites that contain content that’s threatening, harassing, defamatory, or obscene; that infringe on your intellectual property or anyone else’s; or that use software designed to intercept traffic or redirect commissions from other affiliates. That last one is worth flagging. Toolbars and browser extensions that hijack affiliate cookies are a real problem, and if you don’t prohibit them explicitly, you have no standing to remove affiliates who use them.
Beyond website content, you need to address specific promotion methods. The two that cause the most problems are PPC (pay-per-click) advertising and coupon affiliate behavior.
For PPC, the standard approach is to prohibit affiliates from bidding on your trademarked terms in Google, Bing, Facebook, or any other ad network. This includes variations and misspellings. Shutterfly’s agreement lists every trademarked term by name. You should do the same. The penalty for violation should be immediate: forfeit all commissions for a minimum of 30 days and commission set to zero without warning. Soft penalties don’t deter trademark bidding.
For coupons, decide upfront whether you allow coupon affiliates at all. If you do, require pre-approval before any coupon site can promote your program. If you don’t, say so explicitly. Either way, write the policy down. I’ve seen programs get destroyed by coupon affiliates taking credit for sales that were going to happen anyway, because the manager never said coupon sites were prohibited.
Sub-affiliate networks and third-party traffic
Sub-affiliate networks are platforms that aggregate traffic from multiple affiliates and send it through a single account. This can be fine or a complete mess, depending on whether you’ve addressed it in your agreement.
If you allow sub-affiliate networks, require full transparency about where the traffic originates. All sub-affiliates must be bound by your program terms. Any coupon sub-affiliates need pre-approval. And you should prohibit sub-affiliate networks from allowing toolbar or browser extension affiliates without your explicit sign-off. Failure to comply should result in commission reversals for any traffic from non-compliant sub-affiliates.
If you don’t want to deal with sub-affiliate complexity, prohibit it outright. Either is a valid choice. The worst outcome is having no policy, which means you can’t enforce anything.
Geographic and jurisdictional requirements
If you’re running a program in the United States but have affiliates in the EU, Canada, the UK, or Australia, you need to account for that. The two most relevant jurisdictions for online marketing are the United States and the European Union.
For EU affiliates, GDPR applies. Your agreement should include language requiring affiliates to comply with the EU’s Privacy and Electronic Communications Directive if they’re taking orders from EU residents. This isn’t a complete legal solution, but it puts the responsibility on the affiliate to follow applicable laws in their region.
For US-based programs with international affiliates, include a simple clause: affiliates conducting business in or taking orders from other countries are responsible for complying with the laws of those countries. Consult a qualified legal professional in your jurisdiction for the exact language, but the principle is the same: you’re not absorbing liability for what happens in jurisdictions you don’t control.
How to write one without spending thousands on lawyers
You have a few options here. Hiring a lawyer is the most expensive path, typically $300-$1,000 or more for a custom affiliate agreement. That’s defensible for an eight-figure program with major brand risk, but it’s overkill for most programs starting out.
Copying someone else’s terms is the most common path and the most dangerous. You’ll get language that wasn’t written for your business, may not cover your specific products or policies, and could include restrictions you don’t want or miss ones you do. People do this constantly. Don’t.
The middle path is starting with a proven template built specifically for affiliate programs and walking through it section by section. That’s what the Affiliate Terms Wizard does. It’s trained on 1,000+ attorney-written affiliate agreements, walks you through each section with plain English explanations, and produces a finished document in 4-15 minutes. At $49 one-time, it’s one of the better investments you’ll make before launch.
Whatever you use, build in a review cycle. At minimum, revisit your terms once a year. When the FTC updated its affiliate guidelines in 2023, we updated every client’s agreement within a few weeks. It took a few hours total. If you add new products, add them to the trademark list. If you change your cookie window or commission structure, update those terms immediately and notify affiliates of the change.
Also: get your commission structure documented at the same time. What you pay affiliates should be written into the agreement itself, not just referenced verbally or in a separate email. Verbal commission promises create disputes. Written agreements end them.
When to update your agreement and how to notify affiliates
Most affiliate agreements include language reserving your right to update the terms at any time. That’s necessary, but it’s not a license to change major policies without warning. Affiliates who signed up under one set of rules and find themselves bound by completely different ones without notice are affiliates who leave, complain publicly, or stop promoting.
The standard practice is to notify affiliates of any material changes by email before the changes take effect. A “material change” means anything that affects how they earn, what they can promote, or what happens when something goes wrong. Give them at least two weeks’ notice for significant changes. Continued participation in the program after the effective date constitutes acceptance of the new terms.
For minor updates like adding new trademarked keywords or updating FTC language, a one-line note in your next affiliate email is usually enough. The goal is transparency, not bureaucracy. Affiliates who feel informed are affiliates who trust you. That trust is worth protecting, and it costs almost nothing to maintain. The Affiliate Email Pro tool makes it easy to write and send update notifications quickly without burning an hour trying to get the tone right.
One more thing: document everything. When you notify affiliates of a change, keep a record of when the email went out and to whom. If an affiliate later claims they didn’t know about a policy, you’ll have the timestamp. This matters in fraud cases especially. Communication trails are your best protection when things go sideways.
The clauses that protect you from fraud specifically
Fraud prevention starts in the agreement. Catching affiliate fraud after it happens is expensive and time-consuming. Stopping it before it starts is much easier when your terms already define what constitutes a violation and what happens when one is found.
The specific clauses that matter most for fraud prevention are the reversal policy, the communication policy, and the traffic substantiation requirement.
The communication policy is one most programs skip, and it’s one of the most useful. Include language that requires affiliates to respond to your inquiries within a reasonable time, be forthcoming and honest when you ask about traffic sources or specific transactions, and be able to substantiate traffic with clear and demonstrable proof. If any of those requirements aren’t met, you reserve the right to reverse commissions and suspend the account. This gives you a documented basis for action that doesn’t require you to prove fraud beyond a reasonable doubt. Non-responsiveness alone is enough.
Also include explicit prohibitions on cookie stuffing, forced clicks, and any form of automated traffic generation. Cookie stuffing is the practice of placing affiliate tracking cookies on users’ browsers without their knowledge. Forced clicks auto-trigger affiliate links without user intent. Both are fraud, and both should be named explicitly in your agreement. General language about “prohibited practices” won’t hold up as well as naming the specific behaviors.
Finally, include a clause stating that the use of automated processes doesn’t excuse compliance. Some affiliates will claim that a script or platform did something without their knowledge. Your agreement should make clear that it’s their responsibility to make sure their systems comply with your terms, period.
If you haven’t built your program yet and want a comprehensive walkthrough of what goes into launching and running it well, The Book on Affiliate Management covers the full terms and conditions process in an entire chapter, including template language for every section described here. It’s the same system I used to build programs that generated over $1 billion in combined sales. The affiliate agreement is one of the first things I walk new program managers through, because getting it right at the start costs nothing. Fixing it after something goes wrong costs a lot.
Frequently asked questions
Do I need a lawyer to write my affiliate program agreement?
No. A qualified template built on attorney-written agreements, like the Affiliate Terms Wizard, covers the required sections and lets you customize for your program in under 15 minutes. For major programs with significant brand exposure, a legal review is still worthwhile, but it’s not a requirement to launch.
Can I just copy someone else’s affiliate terms?
Technically yes, practically no. Terms written for another business may not reflect your commission structure, policies, or products, and could include restrictions that don’t apply to you or miss ones that do. Start with a template designed for affiliate programs instead.
What happens if an affiliate violates my terms?
Your agreement should define this explicitly: you can reverse commissions, set their rate to zero, and terminate them from the program. Without a signed agreement that covers these consequences, you have limited legal standing to act.
How often should I update my affiliate agreement?
At minimum once a year. Immediately when you add new products, change commission structures, or when regulatory requirements change (like FTC guideline updates). Notify affiliates of material changes by email before they take effect.
Do my affiliates actually have to sign the agreement?
Most affiliate platforms handle this through a “click-to-accept” flow during the application process. Affiliates confirm they’ve read and agreed to the terms before being approved. This constitutes a binding agreement in most jurisdictions. Keep records of when each affiliate accepted.
What should I do if an affiliate claims they didn’t know about a policy?
Point to the agreement they accepted and any email notifications you sent. This is why documenting all communications matters. A clear paper trail resolves most disputes quickly and protects you if the situation escalates.
