The ISO 27001 legal and contractual register is used to identify which laws apply to your organisation, what contractual requirements customers have placed on you, what regulatory requirements there maybe and what standards you are working towards. It is used to evidence that they have been reviewed, agreed and signed off and to show when they will next be reviewed. All of these will inform and influence your information security management system.
Think of it as your personal checklist for all the laws and regulations that affect how you handle information and data.

What Is It?
Simply put, an ISO 27001 Legal Register is a document you create to list all the laws and regulations related to information security that your organisation must follow. It’s a key part of getting and keeping your ISO 27001 certification.
Applicability to Small Businesses, Tech Startups, and AI Companies
This legal register is useful for businesses of all sizes, including small businesses, tech startups, and AI companies.
- Small Businesses: You might think this is just for big corporations, but even small businesses have to handle customer data and follow privacy laws. It helps you avoid big fines and keep your customers happy and trusting.
- Tech Startups: As a startup, you’re probably dealing with lots of user data. A Legal Register helps you build trust with your first customers and gives you a solid foundation for future growth. Plus, it makes you look more professional to investors.
- AI Companies: If you’re an AI company, you’re likely working with vast amounts of data. This makes it crucial to know the rules about data usage, privacy, and even ethical guidelines.
ISO 27001 Legal Register Template
The ISO 27001:2022 Legal Register Template is designed to fast track your implementation and give you an exclusive, industry best practice policy template that is pre written and ready to go. It is included in the ISO 27001 toolkit. It is recording applicable laws, regulations and contractual requirements. It does not constitute legal advice although it does come pre-populated with common UK laws that I have come across over decades in consulting. It can be used globally and is a great foundation and starting point.

Why You Need It
A legal register helps you show auditors (and yourself) that you’re taking your legal responsibilities seriously. It proves you’ve identified all the relevant laws and you have a plan to meet them. Without it, you can’t get certified!
When You Need It
You need a legal register when you’re building your Information Security Management System (ISMS) to meet the ISO 27001 standard. It’s one of the first things you’ll do!
Who Needs It?
Basically, anyone aiming for ISO 27001 certification needs one. This includes:
- Small Businesses: You might think you’re too small, but even a local shop with a website handles customer data, so you need to be compliant.
- Tech Startups: Your whole business is built on data, so it’s super important to know and follow the rules.
- AI Companies: You’re dealing with massive amounts of data, often personal or sensitive, so a legal register is absolutely critical.
Where You Need It
You’ll keep this document as part of your ISMS, so it should be easily accessible to your team. Think of it as a living document, not just a one-time thing. You’ll need to review and update it regularly.
How to Write It
To create a legal register, start by identifying your industry and the countries where you operate. Then, research all the information security and data privacy laws that apply to you. List them out, noting key details like the law’s name, what it requires you to do, and who is responsible for it in your company.
How to Implement It
Once you’ve written it, you need to put it into action. This means making sure the right people are aware of their responsibilities and your company policies reflect the legal requirements you’ve identified.
Examples of using it for small businesses
Imagine you run a small online store. Your legal register might include the General Data Protection Regulation (GDPR) because you collect customer names and addresses. It would also list local consumer protection laws.
Examples of using it for tech startups
If your startup develops a new app, your legal register would include data privacy laws like the California Consumer Privacy Act (CCPA) if you have users in California. It would also list rules about handling sensitive financial data if your app processes payments.
Examples of using it for AI companies
As an AI company, your legal register would be more complex. You’d need to include laws on the use of personal data for training AI models, like the EU AI Act, and potentially intellectual property laws if you’re using copyrighted data.
How the ISO 27001 toolkit can help
The ISO 27001 toolkit is a collection of pre-made documents, templates, and guides. It can make creating your legal register much easier, giving you a ready-made template and guidance on what to include.
