what's the corresponding noun for waive?

Corresponding to what?

In order to waive your rights, you could sign a waiver.

Sorry for this confusing question.

I would like to know the corresponding noun to the verb waive, just like renewal corresponding to the verb renew.
Is this clearer?

BTW, if you understand my question but feel it is not phased well, please tell me how to ask such kind of questions. Thank you very much.

Did khoff's response not answer your question?

Sorry, Khoff, I thougth yours was just the person or document who waive something. Thanks. It is the answer!

Thank you, Grammar for the reminding.

BTW, how should I ask such a kind of questions as I mentioned before?

It seemed okay to me, but you could repeat it, with something like "I know 'to waive' is a verb, but is there a noun form?"
