Trademark classes · By business type
Which trademark classes does a law firm need?
Most law firms register in class 45 (Legal & security).
Legal services have their own class, shared with security and personal services. Firms that also offer commercial or financial advisory work may add the business or financial classes.

Before you file in class 45, make sure the name is free. If it's already taken, your application can be refused — and the £205 IPO fee isn't refunded. Checking takes seconds and costs nothing.

Frequently asked questions
- What trademark class is a law firm in?
- Most law firms register in class 45. Class 45 covers legal & security. You only ever register the classes that match what you actually sell.
- Do law firms need to register in more than one class?
- Often, yes. A trademark is only protected in the classes you register, and you pay a fee for each one. Law firms usually start with class 45, then add others as the business grows.
- How much does it cost a law firm to register a trademark?
- Filing direct with the UK IPO costs £205 for the first class and £60 for each additional class, so a law firm covering class 45 pays about £205. The fee isn't refunded if your mark is refused — which is why checking the name is free first matters. See the full cost breakdown .
