Advisory Agreement Review Checklist: What to Check Before You Sign

If you're using a startup advisor agreement review checklist UK founders actually need, this is it. Advisor agreements look simple on the surface — a few hours a month, some equity, a handshake formalised on paper. But the details matter. Vague scope clauses leave you exposed. Poorly drafted equity vesting schedules cause disputes. Missing IP assignment language means your advisor could technically own work they helped shape. This guide walks you through every clause worth scrutinising before you sign, including what red flags to look for, what must-have protections to insist on, and when the agreement is complex enough that you should escalate to a qualified UK solicitor. Whether you're onboarding your first advisor or reviewing a template someone else drafted, this checklist gives you a structured, UK-specific framework to work from — without needing a law degree to follow it.

Why this matters

Most UK founders sign advisor agreements quickly, often using a template pulled from the internet with no UK-specific legal grounding. The real problem isn't the paperwork — it's what gets missed. An advisor who leaves after three months but retains unvested equity. A confidentiality clause that doesn't hold up. An IP clause that's silent on who owns introductions, strategies, or co-developed materials. These aren't edge cases; they're common disputes. By the time the relationship sours, unpicking a poorly drafted agreement is expensive and distracting. This page exists to help you catch those problems before you sign, not after.

The Atornee approach

Atornee isn't a law firm and doesn't replace one. What it does is give UK founders a fast, structured way to review documents like advisor agreements before deciding whether to sign, push back, or escalate. You upload your agreement, Atornee flags clauses worth questioning — vague deliverables, missing vesting schedules, weak IP assignment language — and explains what each issue means in plain English. It's the step between 'I've received this document' and 'I know what I'm looking at.' For straightforward agreements, that's often enough. For complex or high-stakes arrangements, Atornee tells you clearly when a solicitor should be involved.

A reusable checklist framework you can apply to every advisor agreement you sign going forward

Before you sign checklist

1
1. Confirm the agreement is governed by English and Welsh law (or Scottish law if applicable) — don't assume it is
2
2. Check the scope of services clause: is what the advisor will actually do written down specifically, or is it vague?
3
3. Review the equity or compensation terms: is there a vesting schedule with a cliff, and what happens if the relationship ends early?
4
4. Look for an IP assignment clause: does it explicitly assign any IP created or contributed by the advisor to your company?
5
5. Check the confidentiality clause: does it cover both directions, and is the duration clearly stated?
6
6. Identify any non-compete or non-solicitation terms: are they proportionate, time-limited, and enforceable under UK law?
7
7. Escalate to a UK solicitor if the agreement involves significant equity, exclusivity, or clauses you cannot interpret with confidence

FAQ

Does a startup advisor agreement need to be reviewed by a solicitor in the UK?

Not always. For straightforward arrangements — limited equity, clear scope, standard confidentiality — a structured review using a checklist or AI tool is often sufficient. But if the agreement involves meaningful equity, exclusivity obligations, or clauses you're unsure about, a UK solicitor is worth the cost. Getting it wrong is more expensive than getting it reviewed properly upfront.

What are the biggest red flags in a UK startup advisor agreement?

The most common red flags are: no vesting schedule or cliff on equity, a vague or undefined scope of services, missing IP assignment language, a confidentiality clause with no time limit, and non-compete terms that are disproportionately broad. Any of these can create real problems if the relationship breaks down.

Is advisor equity taxable in the UK?

Yes, it can be. Equity granted to advisors may be subject to income tax and National Insurance depending on how it's structured. EMI options are not typically available to advisors who aren't employees. You should take specific tax advice before agreeing equity terms — this is one area where a solicitor or accountant is genuinely necessary.

What should a UK advisor agreement include as a minimum?

At minimum: a defined scope of services, compensation or equity terms with a vesting schedule, an IP assignment clause, a confidentiality obligation, termination provisions, and governing law. If any of these are missing, the agreement is incomplete and should be revised before signing.

Can I use a US advisor agreement template for a UK startup?

No. US templates are drafted under US law and often reference legal concepts that don't apply in the UK — including certain IP assignment mechanics, tax structures, and enforceability standards. Always use a UK-specific template or have a UK solicitor adapt one. Using the wrong template creates gaps that are hard to fix later.

What happens if an advisor agreement doesn't include an IP assignment clause?

Without a clear IP assignment clause, any intellectual property the advisor contributes to or creates during the engagement may remain theirs under UK copyright and IP law. This is a serious risk, particularly if the advisor helps develop product strategy, branding, or technical approaches. Always insist on explicit IP assignment language before signing.
