There is no official template for writing DMCA notices, and at the same time, you do not need to be a lawyer to send them out.

If you decide that you want to file a termination and that it is correct, you might want to consider the first tool is the DMCA Takedown Service, which is a partner of Plagiarism Today, to get some help and take the headaches out of the filing.
