Stud Contracts - Per  the AKC

Agreements between individuals concerning stud fees should be in writing and clearly state all obligations and circumstances. The contract should be signed by all parties to the transaction and each signer thereto should receive a copy.

The stud fee is set by the stud dog’s owner. The mode of payment may differ. The stud owner may request a cash fee, "pick of the litter", one or more puppies from the resulting litter, etc.. The collection of the stud fee is the stud owner’s responsibility.

The American Kennel Club takes the position that the owner of the sire is required to sign an application to register a litter certifying only to the fact that a particular dam was bred to the sire identified on the Litter Registration Application form on a specified date of mating, unless there is an agreement signed by all parties concerned in which it is specifically set forth that the owner of the sire is not obligated to sign an American Kennel Club litter registration application form until such time as the stud fee has been paid.
