PLEASE HELP!!!! I WILL GIVE BRAINLIEST!!!

State law recognizes that the owner of a vehicle is the person or company whose name appears on the title, or legal and official ownership document. The state also recognizes payment agreements that people and businesses make through official, legal means.

A young woman says her neighbor agreed to purchase her old car. She agreed to accept payments from him on a monthly basis until he paid off the car and trusted that he would honor this plan. She signed ownership over to him on the title, which he also signed. She says that he has not made any payments and still has possession of the car.

The neighbor says he understood the car to be a gift and has no obligation to make payments. He did not sign an official agreement to make payments. He says that she gave him the car in exchange for his electric scooter, which is new and gets great gas mileage. The neighbor maintains she just wants the car back now that he fixed it and it looks better.

Is the source of the law a statute, regulation, case law, or combination? How do you know?
