I just bought my boat in March in ND. They don't have titles for boats or the trailers for them. They have a registration for the boat, which is what you need to license it here. The trailer will have no registration at all. Mine didn't even have a VIN. I had to have some type of law enforcement, ie. FWP, Sheriff, Police or State Trooper inspect the trailer and verify there was no VIN. Then I went to DMV and paid for a VIN for the trailer. I took a strip of aluminum and stamped the VIN on it, and riveted it to the tongue. Then had the law enforcement guy inspect it again, (preferably the same officer, so as to not have to explain the whole thing over again). Then I got the title and registration for the trailer. I know it sounds like a nightmare, but it really wasn't that bad. I did some research and found this and printed it and took it with me:
https://www.dot.nd.gov/divisions/mv/docs/faqtrailers.pdf They may want to argue that they require registrations for a boat trailer in ND. Refer them to the 5th line, the 2nd bullet, where it describes trailers not requiring registration which includes trailers used to haul boats. There are good deals on boats and stuff in ND now with the Bakken slowed down.
This is where I found my boat.
