Custom Built Car Registration in South Dakota

- How to Register
- After You Register
Page OverviewWhether you have a custom-built car or a minivan, the registration process is the same.
(If you've just moved to South Dakota, you'll have 90 days to register your custom-built car here.)
How to Register
Visit your county treasurer's office with:
- A completed Power of Attorney form (only if someone other than the vehicle owner is to sign the registration)
- A completed bill of sale, purchase order, or sales contract (for out-of-state vehicle purchases only)
- Identification
- Payment for license fee
Once you've properly registered your car and paid the fees, you'll be given the registration paper which needs to be kept in the car.
After You Register
You'll need to renew your registration every year on a schedule determined by the first letter of the vehicle owner's last name.
Of course, you'll also have to get a title for your car, and pay fees for that, too. Again, this will occur at the county treasurer's office. We talk about the titling process in our Title Transfers section.
For more information on the registration process, check out the state's registration home page.
