If you make a fake version of a registered trade mark to try to make money or cause someone to lose money, you are breaking the law. This is called counterfeiting a registered trade mark.

There are two main ways you can counterfeit a trade mark:

You can make a new sign that looks just like, or very similar to, the real trade mark. If you do this on purpose to trick people, it's illegal.

You can also take a real trade mark and change it. This could mean adding to it, taking parts away, or altering it in any way. If you do this to make it look different, it's also against the law.

Remember, you can only do these things if the owner of the trade mark says it's okay. If you don't have their permission and you do it anyway, knowing that it's wrong, you're committing a crime.
