Plain language standard part 2: Legal communication
Do you work with legal communications and wonder how you can make documents more accessible for your clients? You’re in luck, because the International Organization for Standardization (ISO) has released part 2 of their plain language standard with a focus on legal communication.
ISO is a non-governmental organisation that consults with experts from around the world to agree on the best way of doing things.
Part 2 of the standard sets out tips for authors to use to help readers understand legal communication and exercise their legal rights and responsibilities. It also builds on the foundation for plain language in part 1 of the standard.
Who’s the standard for?
The standard is for writers and readers of legal communication.
The standard steps out how authors can write in plain legal language. This is legal communication that is written, structured and designed in a way that means readers can easily:
- find what they need
- understand what they find
- use that information.
Overview of the standard
The guidelines in this standard are based on the 4 principles from part 1. These principles are:
- Relevant – readers get what they need
- Findable – readers can easily find what they need
- Understandable – readers can easily understand what they find
- Usable – readers can easily use the information.
The standard explains how authors can apply principles from part 1 in legal contexts that require them to:
- reach multiple audiences with different needs
- legally meet structural and design requirements
- explain complex and nuanced legal ideas
- explain processes that readers must navigate to exercise their legal rights and responsibilities.
Within these principles, the standard provides guidelines for:
- collaborating with all experts from the start
- minimising the need for readers to refer to other documents
- using consistent terms for the same concepts
- reviewing your content and getting feedback from your audience.
Part 2 of the standard also includes a checklist to use when you’re developing content in plain legal language. The checklist is organised by the plain language principles and asks questions to help authors apply the guidelines.
Who does plain language benefit?
Plain language is for everyone. It makes communication accessible for more people, whether your audience is specialists, colleagues, clients or friends.
Writing in plain language allows your audience to understand your content the first time they read it. This is particularly important in legal contexts, where you might require your reader to act on what you’ve written or understand their obligations.
Plain language helps you meet these aims. It can improve your relationship with your audience as well as save you time and resources.
