South Dakota Bill of Sale Rules
The specifics for South Dakota, taken from the South Dakota Motor Vehicle Division and South Dakota law. Every source is linked at the bottom of this page.
Form 1025
South Dakota publishes its own vehicle bill of sale, Bill of Sale (Form 1025). Using the state's form is the safest option — it already contains every field the South Dakota Motor Vehicle Division looks for.
45 days
The Department of Revenue states titles must be updated within 45 days of the purchase date; interest on the 4% motor vehicle excise tax begins after 45 days and a separate 10% penalty applies after 60 days.
Bill of Sale (Form 1025)
This is the form South Dakota issues for a vehicle bill of sale. It already contains every field the South Dakota Motor Vehicle Division looks for, which is why it is worth using instead of a generic template.
Find Form 1025 at dor.sd.govHow South Dakota Compares With the Other 49 States
Vehicle paperwork is written state by state, so an instruction that is correct in one place can be actively wrong three hundred miles away. This is where the South Dakota rules sit relative to everyone else's.
The official form
Of 40 of the 50 states where we established the answer, 25 issue their own bill-of-sale form and 15 do not. South Dakota is in the first group. Use the state's own version rather than a template — a generic form is legal here, but it is also the one a clerk has to read line by line.
Whether the document is required
Whether South Dakota requires a bill of sale is not something we could establish from a South Dakota Motor Vehicle Division source, so this page does not claim an answer either way. Nationally the split runs 8 always, 23 sometimes and 11 never. Sign one regardless — it is free, and it is the only dated record either party keeps.
Notarization
The notary question is unresolved for South Dakota in our research, and we will not fill that gap with a guess about a step you would have to plan the meeting around. For reference, notarization is the exception nationally rather than the rule: 23 states publish that it is not needed.
The buyer's deadline to apply for title
South Dakota gives the buyer 45 days — 29 states are tighter, 3 looser, and one other runs exactly the same clock, out of the 34 that publish a calendar-day figure. What the number does not tell you is how long a lien release takes to arrive from a lender, so treat 45 days as the outside limit rather than the plan.
What Goes on a South Dakota Bill of Sale
South Dakota issues Form 1025, so start there — but whichever form you use, a complete bill of sale always captures these four things:
Buyer & seller details
Full legal names and addresses of both parties, so the South Dakota Motor Vehicle Division can tie the sale to real people.
Odometer reading
The exact mileage at the moment of sale — a legal disclosure that protects against rollback fraud.
Vehicle description & VIN
Year, make, model, body style, and the full 17-character VIN that ties everything to the car.
Price, date & signatures
The agreed price, the date of sale, and both signatures — notarized if South Dakota requires it.
How a Private Sale Transfer Works in South Dakota
Titling in South Dakota is handled by the South Dakota Motor Vehicle Division. Fees depend on the vehicle, but the paperwork flow in a private sale is always the same — here is how the bill of sale and the title move together.
- 1Complete the bill of saleFill in the buyer and seller details, sale price, date, odometer reading, and the full VIN. Use South Dakota's own form, Form 1025 — it already has every field the South Dakota Motor Vehicle Division checks. Both parties sign.
- 2Sign over the titleThe seller signs the existing South Dakota title over to the buyer in the assignment section, recording the same sale price, date, and odometer reading shown on the bill of sale.
- 3File with the DMVThe buyer brings the bill of sale, signed title, odometer disclosure, and proof of identity to the South Dakota Motor Vehicle Division to transfer the title, pay any tax due, and register the vehicle. In South Dakota the buyer has 45 days from the date of sale to do this.
South Dakota Vehicle Transfer Documents
The bill of sale is one of several papers that change hands when a car is sold in South Dakota. These are the documents a private transfer usually involves:
Bill of sale
Proof of purchase the South Dakota Motor Vehicle Division uses to calculate sales tax: who, what, when, how much, and the VIN.
Signed-over title
The primary ownership document. The seller assigns the South Dakota title to the buyer in its assignment section.
Odometer disclosure
A required mileage statement, often built into the title or bill of sale, guarding against rollback fraud.
Lien release
If the car had a loan, the lender's release proving the lien is paid so a clean title can transfer.
South Dakota titling authority
Vehicle titles and transfers in South Dakota are handled by the South Dakota Motor Vehicle Division. About 1.1M vehicles are registered across the state, and every transfer is recorded against the VIN — so the documents you sign should always match the VIN on the car. See the South Dakota vehicle title guide for the title side of the transfer.
Why Check the VIN Before You Sign in South Dakota
The bill of sale records what the seller claims. A free VIN check shows what actually happened to the car — before you put it in writing.
Confirm the odometer reading. The mileage you write on the South Dakota bill of sale is a legal disclosure. An odometer rollback means the figure the seller gave you is wrong — and the car is worth less.
Make sure the title is clean. A bill of sale can't undo a salvage brand. Check that the title has no hidden brand before you agree on a price.
Rule out an open lien. If a previous owner's loan was never paid off, the title can't pass to you cleanly. A South Dakota lien check surfaces it before money changes hands.
Check before you sign
Enter the 17-character VIN to confirm the title is clean, lien-free, and the mileage checks out — everything you want verified before the South Dakota bill of sale is signed.
Where South Dakota Private Sales Go Wrong
Read this part before the meeting rather than after it. Each of the following is trivial to get right while both parties are standing there, and genuinely difficult once the car has changed hands.
- 1
Only one copy exists
Both parties need one, and the seller needs theirs more. The buyer has the car; the seller has nothing but a document proving when they stopped being responsible for it — which is what answers a parking ticket, a toll bill, or a police enquiry six months later. Make two copies, sign both, and keep yours somewhere you will still be able to find it. Photographing it on the spot takes five seconds and has saved a great many arguments.
- 2
The two signatures were made at different times
A bill of sale is a record of a moment, and both parties are meant to be at it. South Dakota does not require a notary, but the same logic applies — a document one party signed and posted is far weaker evidence than one both parties signed together. Sign the same piece of paper, at the same time, and make the second copy before you part.
- 3
The date is missing, or moved
The date of sale is what every subsequent clock runs from. In South Dakota the buyer has 45 days from it to apply for title, so backdating the document to cover a delay does not buy time — it spends it. It is also the line either party points at when a ticket, a toll or an insurance claim arrives for a day neither of them owned the car. Leave it blank and there is nothing to point at.
- 4
The seller's name is not the name on the title
If the person selling the car is not the registered owner, a bill of sale between the two of you transfers nothing. This is what an unrecorded middle owner looks like, and it leaves the buyer holding a car they cannot title. Ask to see the South Dakota title and check the name on it against the identification of the person in front of you. Where the owner has died or the car is being sold by a dealer on someone's behalf, the South Dakota Motor Vehicle Division has a defined process — and it is not a private bill of sale.
- 5
The odometer box is empty
The mileage is a legal disclosure, not a courtesy, and "as is" or a dash in that box is the commonest reason a bill of sale gets handed back. Write the exact number showing on the dashboard, not a rounded one, and write the same number on the title assignment. If the two documents disagree the transfer stalls, and the version the South Dakota Motor Vehicle Division believes is the one that makes the buyer's car worth less.
- 6
Something has been crossed out
Alterations are read as tampering, especially on the title. A struck-through VIN, a corrected mileage figure or a whited-out name is usually enough for a clerk to reject the document outright, and on a South Dakota title it can mean applying for a duplicate before the transfer can go ahead at all. Start a fresh sheet instead. A bill of sale costs nothing to reprint and a duplicate title costs a fee and a wait.
What the Bill of Sale Starts, and What Finishes It in South Dakota
Signing is the middle of the process, not the end of it. Each step below is a separate South Dakota record with its own rules, and a problem in any of them surfaces after the money has moved unless you look first.
The title is the transfer; the bill of sale only records it. This is the single most expensive misunderstanding in a private sale — a signed receipt and a set of keys do not make you the owner in South Dakota, and a buyer who never completes the assignment finds out when they try to sell the car on. What the seller has to sign, where the odometer statement goes, and what to do when the title is lost are all covered in the South Dakota vehicle title guide.
Nothing moves while a lien is open. If the seller still owes money on the car, the lender holds the security interest and the South Dakota Motor Vehicle Divisionwill not print a clean title in your name until it is released. That release usually comes by post from the lender, which is why the buyer's deadline is rarely the real constraint. Establish whether a lender is on the record with a South Dakota lien check before you hand over cash, not after.
The mileage you write down is a legal statement. The odometer figure on the bill of sale and the one on the title have to agree, and both have to be true — a reading that is lower than a previously reported one is the signature of a rollback, and it is the buyer who carries the loss. Compare every reading ever filed against the VIN in the South Dakota odometer check.
A brand travels with the car, not with the seller. If the vehicle was written off at any point in its life, the brand is attached to the VIN and it follows the car into South Dakota whichever state applied it. No bill of sale can remove it, and no verbal assurance survives contact with the title. The South Dakota salvage title check shows what is recorded against it.
Then the plates. Titling and registering are two different transactions, and the second one is what puts the car legally on the road — with its own proofs, its own fees and, in some counties, its own inspection. The requirements are set out in the South Dakota vehicle registration guide.
Or do all of it at once. Title brands, reported mileage, theft records and open liens are all keyed to the same 17 characters, so there is no reason to check them one at a time. The South Dakota VIN check runs them together, before the bill of sale is signed rather than after.

South Dakota Bill of Sale FAQ
The questions South Dakota buyers and sellers ask most about the bill of sale and the documents a private car sale needs.
What goes on a bill of sale in South Dakota?+
A South Dakota bill of sale records the full names and addresses of the buyer and seller, the sale date, the purchase price, the vehicle's year, make, model, and body style, the exact odometer reading, and the 17-character VIN. Both parties sign it. South Dakota publishes an official form, Bill of Sale (Form 1025); using it is the safest option because it already has every field the South Dakota Motor Vehicle Division checks. Confirm the VIN on the bill of sale matches the title and the dashboard before signing — and run a free VIN check first to verify the title is clean and lien-free.
How long do I have to transfer a title in South Dakota?+
45 days from the date of sale. The Department of Revenue states titles must be updated within 45 days of the purchase date; interest on the 4% motor vehicle excise tax begins after 45 days and a separate 10% penalty applies after 60 days. This is the buyer's deadline to apply for title — a seller's duty to report the sale, where one exists, runs on a separate clock.
Is South Dakota unusual about bills of sale?+
South Dakota publishes its own form, which 25 states do and 15 do not. On whether the document is required at all, the country splits 8 always, 23 sometimes and 11 never, out of the 42 states publishing a rule. Notarization is the real outlier: 23 states say it is not needed, 10 require it in certain transfers, and 2 require it every time (Louisiana and West Virginia).
Is 45 days a long time to transfer a title?+
It is on the generous side. Across the 34 states that publish a calendar-day deadline for the buyer, the figure runs from 10 days to 60, and 30 days is the commonest single answer — 18 states use it. 29 states give buyers less time than South Dakota does and 3 give more. The clock starts on the date written on the bill of sale, so do not backdate it to cover a delay: that shortens your own deadline. Where the car had a loan, the real constraint is usually how long the lender takes to send a lien release, not the South Dakota Motor Vehicle Division's deadline.
Can I use an out-of-state bill of sale in South Dakota?+
Usually yes for the document itself — a bill of sale is a record of a transaction, and South Dakota does not reject one because it was typed on another state's template. What does not travel is the procedure around it: 2 states require notarization and the rest largely do not, deadlines to apply for title range from 10 to 60 days, and 25 states publish a form with fields the other 25 never ask for. If you are buying across a state line, the rules that bind you are the ones where the car will be titled, not the ones where it was sold. Run the VIN before you cross the line either way — a brand applied in one state follows the car into the next.
What documents do I need to buy a used car in South Dakota?+
Besides the bill of sale, you'll typically need the South Dakota title signed over by the seller, an odometer disclosure (often part of the title or bill of sale), a lien release if the car had a loan, and your own proof of identity and insurance to register it with the South Dakota Motor Vehicle Division. A free VIN history check isn't legally required, but it's the smartest document to add — it confirms the title is clean before money changes hands.
Why check the VIN before signing a bill of sale in South Dakota?+
The bill of sale records what the seller claims; a VIN check shows what actually happened to the car. Running the 17-character VIN before you sign confirms the title is clean, the odometer reading is consistent with the car's history, and there's no open lien that would block the transfer at the South Dakota Motor Vehicle Division. It's free and takes seconds.
Are there any specific titling rules in South Dakota?+
South Dakota only titles vehicles model year 1976 or newer, so older vehicles often rely solely on VIN history reports.
