Oh I would love to go to court on that one.. being sued for receiving a $1.00 check that was never cashed LOL... imagine the publicity for that one... wow.. just wow !
You wouldn’t be sued, what you could do is harm your candidate by giving ammunition for a challenger to post a FEC challenge/complaint against him. It isn’t how much he pays anyone, it is how the campaign is run. This is the basics like putting on your seat belt before you drive.
