In Chapter $16$ the author presents a case example in which a woman, Tammy Herring, contracted to buy a horse from Stacy and Gregory Bowman. The agreement was that the horse would stay with the Bowman's until Tammy paid for the horse in full. Also, Tammy would pay the Bowman's a monthly boarding fee for the horse. Once the horse was fully paid for, the sellers would sign the official registration papers over to Tammy.

Before the horse was paid for, there was an accident in which a person was thrown from a buggy being pulled by the horse. The buggy was being driven by the seller's daughter. The person who was injured sued for damages because of the accident. One of the defendants was Tammy Herring since the plaintiff alleged she "owned" the horse at the time of the accident. Tammy claimed she did not have title to the horse since the registration papers had never been signed over to her.

Did the court rule that Tammy owned the horse even though she did not have the official registration papers for it yet?

Yes

No$.$ Tammy did not own the horse until the registration papers were signed over to her. The Bowmans still owned the horse at the time of the accident.
