Do I need to title a trailer?
It depends on the trailer’s weight and your state. Heavier trailers usually require a title and registration; many small utility trailers only need registration. Check your state page.
What if my trailer has no VIN?
Homemade or older trailers may need a state inspection to be assigned a VIN before they can be titled. The bill of sale still documents the sale in the meantime.
Is a bill of sale proof of ownership?
Generally no. For titled property like a car or boat, the title is what proves ownership. A bill of sale proves that a sale happened and records the price, date, and terms — it supports the title transfer but does not replace it. For untitled property (furniture, equipment, electronics), the signed bill of sale is usually the main proof of ownership.
