How to dispute
Go to the copyright notices section of your Video Manager.
Click the underlined link to the right of the video's Edit menu. This will take you to a page with information about what’s been claimed in your video and who claimed it.
If you believe that this claim was made in error, you can dispute it directly from this page.
If you previously acknowledged that the claim is valid, but have since determined you possess all necessary rights to the content in your video, you can still dispute the claim.
