N.D. Cent. Code § 39-18-03
The owner of a travel trailer, housetrailer, or mobile home, who sells or transfers the title to such vehicle shall endorse an assignment and warranty of title upon the certificate of title for such vehicle, along with a statement as to whether there are liens or encumbrances thereon. The owner shall deliver the certificate of title to the purchaser within fifteen days after such sale if title passes to the purchaser. If the legal title does not pass to the purchaser under the contract for sale of the vehicle, the legal title owner shall endorse thereon a statement that the owner holds the lien, the date thereof, and the name of the purchaser, and shall send the certificate of title to the department with an application of the purchaser for a new certificate of title showing the name of the legal owner, the registered owner, the date of the lien of the legal owner, which certificate of title when issued must be returned by the department to the legal title owner; who shall retain the same in the owner's possession until the terms of the contract are complied with by the purchaser, and thereupon, after showing that the lien has been paid and satisfied the owner shall deliver the certificate of title properly assigned to the purchaser. The purchaser or transferee shall present the endorsed and assigned certificate to the department, within thirty days after the receipt thereof, accompanied by a transfer fee of five dollars, and shall make an application for and obtain a new certificate of title for such vehicle. A penalty of not more than ten dollars may be imposed by the director for failure to present the certificate of title to the department as required by this section. Except when transported by a drive-away transporter duly registered and licensed under the laws of this state, no person may haul a mobile home, housetrailer, or travel trailer unless the same is first registered with and titled by the department, a certificate of title has been issued, and it displays a number plate issued by and under such regulations as the director may prescribe. The annual fee for such licensing is twenty dollars for mobile homes and housetrailers and twenty dollars for travel trailers.
The registration required hereunder must be on a calendar-year basis.
If such mobile home, housetrailer, or travel trailer enters the state carrying the current number plate of another state, no number plates may be required by the state of North Dakota for a period of thirty days.
The annual license fee provided for in this section does not preclude the taxation of certain mobile homes pursuant to chapter 57-55.
If such mobile home, housetrailer, or travel trailer remains stationary or parked within the state of North Dakota for a period of one year, no license may be required for that year, provided that nothing in this chapter permits the use of a dealer's plate on such mobile home, housetrailer, or travel trailer after the same has been sold by the dealer to whom such plate was issued.
