An athlete agent or financial services contract is deemed filed when it is properly addressed and placed in the United States Post Office or in the hands of a common or contract carrier or successfully transmitted by fax or by e-mail. The post office cancellation mark, the receipt mark of a common or contract carrier, a fax transmission report, or confirmation of receipt of e-mail is prima facie evidence of the date the contract was deposited with the post office or carrier or transmitted by fax or e-mail.
