A person is prohibited from entering a filly or mare in a race when the filly or mare is pregnant, unless prior to the time of entry the owner has deposited with the racing secretary a signed agreement providing that the owner will at the time of entry provide for the successful claimant of such mare, without cost, protest, or fee of any kind, a valid stallion service certificate covering the breeding of the filly or mare. A successful claimant of a filly or mare may file with the commission a protest for cancellation of the claim if it is determined the claimed mare is pregnant and the agreement concerning the stallion service certificate was not deposited as required by this section. An in-foal filly or mare will be eligible to be entered into a claiming race only if the following conditions are fulfilled:

(1) Full disclosure that the filly or mare is in foal is on file with the racing secretary and the information is posted in his/her office;

(2) The stallion service certificate has been deposited with the racing secretary's office and attached to the horse's foal registration certificate;

(3) All payments due for the service in question and for any live progeny resulting from that service are paid in full.

(4) No filly or mare in foal may race, in a claiming race, after the fifth month of pregnancy.
