My question involves a consumer law issue in the State of: California
My dad gave me a van as a gift for a whole year. The title of the vehicle is under my name and the registration, also got the smog check, and even insured the vehicle. I have been maintaining the vehicle as far as gas, maintenance, etc. 5 months later my dad tells me he needs money and wants to sell the van for $1800 either to me or someone else. The van needs a lot of fixing such as back brakes, mechanical malfunctions, alternator, etc (which he said he would fix, and never did). And therefore it would cost me a lot more to fix and that I'd rather buy a vehicle in better condition that i won't have to fix. He agreed he'd give me 3 months to save money and buy a car and that he would sell my van last from the other 3 that he has to give me time. 2 weeks after the agreement, he shows up to my house with a buyer, and asks for the keys of the vehicle because he wants to sell the van. He says its his van, when in fact the van was never under his name to begin with and says has the rights to sell it if he wants. The vehicle is under my name. I told him he violated our agreement and that i was counting on him to keep his word in order for me to save money for a car. He refuses and says he really needs the problem and I have no say because he gave it to me and he can take it and sell it. He threatened to come tomorrow and take the vehicle whether I agreed to him selling it or not.
From my understanding, I am the owner of the vehicle, everything is under my name and to sell it I would have to sign to sell the vehicle( which i don't plan on doing til i find a car to buy, after all i'll be without a car). What can be done about this? Does he have any rights over my car? Can i legally withhold him from selling it? I need an answer
