For my financial disclosure do they legally have the right to make me provide this?!?

So my ex demanded I give him a copy of all of my EBAY account activity for the past year and a half. Ebay only keeps records that go back 30 days. So now he is demanding that instead I send him a copy of all of my "feedback" as part of the financial disclosure. I don't understand what my Ebay feedback has to do with financial disclosure. Does he have the right to ask for and do I have to provide something like this??
