Entrance, nomination, and starting fees.
(1) A horse may not start in a race unless all stake or entrance fees required for that race have been paid.
(2) Nomination and entrance fees may not be refunded due to the death of a horse, or a horse's failure to start.
(3) The owner is liable for the nomination and/or entrance fees. The death of a horse or a mistake in its entry does not release the owner from having to pay these fees.
