This is an unfortunate double-standard in the DMCA -- to file all you have to state under perjury you are acting on behalf of the party whose work is claimed to be infringed. The claim of infringement itself does not have to be stated under penalty of perjury.

On the other hand, in the counter-takedown notice you have to state under penalty of perjury that the material was removed by mistake or misidentification. It's a scary thing to do unless you can afford a lawyer.
