Or are you saying that by having a late fee in your contract, and then not enforcing it, you are negating THAT contract...
I have always heard it nulled it for all parents. Possibly meaning since you have the same contract for everyone but not following the contracts and it just voids them out?
I'll see if I can find something in one of my books.
