this is for real estate- if earnest money is not delivered on time by the designated broker who would be informed first? the client or the title company?

when a person is helping a firm get a client ( who has a license)and the firm said they would pay them a little commission when do they get payed? after closing, during closing, before closing or after closing and not on the agreement at all.

last question- when would a attorney be able to do real estate activities without having a real estate license? would it be when they dont get a commission when they do or not at all they cant.
