§ 21310 Unlawful Use Of Association Insignia

• •You must have written permission or be allowed by the group’s rules before using its name or insignia.
• •If you use it without permission, the law assumes you are doing something illegal.
• •The presumption can be used as evidence in court against you.

A person prints T‑shirts with a local charity’s logo without asking the charity first.

Because they didn’t have written permission, the law treats that use as evidence that the person is illegally using the charity’s name and logo.
