Our family business has been serving customers for 25 years. Recently, we noticed another company using a very similar name and logo to ours. We never registered our company name or logo. What can we do to prevent them from using our brand identity?

As you haven’t registered your company name or logo, you lack legal protection under trademark law. You can try sending a cease and desist letter, but it’s unlikely to be effective without existing registration. Consider registering your brand identity immediately to protect it going forward.
