Answer: Donee Beneficiary
Step-by-step explanation:
A Donee Beneficiary is someone who stands to gain a gift from a contract or transaction between two other parties.
Octavio stood a chance to get tickets to Jerry Seinfeld due to a transaction that his girlfriend Amanda had entered into with Jennifer thus making him a Donee.
Once the transaction has been completed and paid for, the Donee has the legal right to demand that the gift that was promised to them is actually delivered because that was the condition of the contract which means also that should Octavio decide to pursue the matter, he has a legal right to enforce the delivery to him by Jennifer.
