A family friend has a 10 foot flat bottom boat with an outboard motor he is going to sell me while I'm home on leave in Utah. It is registered in Utah as is the trailer. But neither come with a title. So if I bring it back to California how do I go about getting these two legal? Ive been on DMV website and its spoken so vague especially on the trailer. Do I just bring the Utah registration for both and a bill of sale for both to the DMV?
