A contract is not possible to “break”. That is, once agreed to, the title will instantly be transferred under the arranged conditions, and this cannot be prevented. If one was to fail to cede their direction of a good after the title was transferred, they would be guilty of theft, as the contract would’ve already gone through, and they would no longer hold the title.1
An example could be someone transferring title of a cheeseburger to another individual. After the transfer is complete, the person does not give up their direction of the burger. They are not guilty of breaking the contract (which has already been completed), they are guilty of theft, as they are taking unjust direction of the good which is now owned by another party.
