ARSD 20:04:24:85. A horse sold with engagements

When a horse is sold with its engagements or any part of them, the seller may not declare it out of any of the engagements.

When the horse is sold by public auction, the advertised conditions of the sale are sufficient evidence that only the engagements specified were sold with the horse.
