What happens if you use a trademark without permission?

A trademark owner who believes its mark is being infringed may file a civil action (i.e., lawsuit) in  court  for trademark infringement, depending on the circumstances

It would not be a problem till the time some party opposes your use or someone uses a mark similar to yours.

Registering a trademark is not a legal mandate, its more about protecting your intellectual property.

If you register your mark then no other party shall be able to use it and if they do then you can take legal action against them.

Hello, Inquirer. I see that your query is related to The Trade Marks Act, and  Lawyers Club India (LCI) offers specialized classes on this subject to enhance your practical understanding and overall knowledge.
