Bill of Sale Aug 21, 2026
Buying or selling a car in Delaware? A bill of sale is one of the simplest documents in the entire process, but it's also one of the most misunderstood. Many people assume it's mandatory in every transaction. Others skip it entirely and later run into title or registration delays at the DMV.
This guide breaks down exactly when Delaware requires a bill of sale, what it must include, how the state's document fee works, and how to avoid the small mistakes that slow down a title transfer. If you're planning to sell privately, KarKiosk can help you list your car, connect with serious buyers, and move through the paperwork with less guesswork.
What Is a Delaware Bill of Sale?
A bill of sale is a written record of a vehicle transaction between a buyer and a seller. It documents the sale price, the date of the sale, a description of the vehicle, and the signatures of both parties. Think of it as a receipt with legal weight.
According to the Delaware Division of Motor Vehicles (DMV), a bill of sale from a dealer is one of the standard documents requested when a vehicle is presented for a Delaware title application. For private sales, it isn't always a formal requirement, but it fills an important gap the title alone doesn't cover.
Is a Bill of Sale Required in Delaware?
Here's where a lot of confusion starts. Delaware does not issue an official state bill of sale form, and the DMV does not always demand one for every private-party transaction. Instead, the state relies heavily on the vehicle's title, which includes a seller's report of sale section on the back.
That said, the DMV's own dealer documentation requirements confirm that a copy of a bill of sale is required when a licensed dealer submits paperwork for titling, in line with Delaware Code Title 21, Section 6305, as noted on the Division of Motor Vehicles dealer FAQ page. For private sales, having one is strongly recommended because it:
Proves the agreed purchase price for document fee purposes
Protects the seller if the buyer disputes the sale later
Gives the buyer a paper trail if the title has an error
Speeds up the process if the DMV requests price verification
Bottom line: even when it isn't strictly mandatory, skipping the bill of sale removes a layer of protection both sides usually want.
What Information Should Be on a Delaware Bill of Sale
A complete bill of sale should hold up on its own, without anyone needing to guess at missing details. Based on documentation requirements referenced by the Delaware DMV, here's what to include:
| Section | Details to Include |
|---|---|
| Buyer information | Full legal name, address, signature |
| Seller information | Full legal name, address, signature |
| Vehicle description | Year, make, model, color, VIN |
| Odometer reading | Mileage at time of sale, per federal odometer disclosure rules |
| Sale details | Purchase price, date of sale |
| Payment terms | Full payment or balance due date, if applicable |
| Condition statement | "As-is" or any warranty terms agreed upon |
A short, clear document beats a long, vague one. Stick to facts, keep language plain, and make sure both signatures are dated the same day the deal closes.
Delaware's Vehicle Document Fee Explained
Delaware doesn't charge traditional sales tax on vehicle purchases. Instead, it applies a document fee, and this is where a lot of buyers get caught off guard because the rate recently changed.
As of October 1, 2025, the document fee is 5.25% of the purchase price or the vehicle's NADA trade-in value, whichever is higher, according to an official notice from the Delaware Division of Motor Vehicles citing House Bill 164. This replaced the previous, lower rate.
| Purchase Price Range | Document Fee |
|---|---|
| $0 – $399 | Flat minimum fee of $8.00 |
| $400 – $500 | Flat minimum fee of $13.75 |
| Above $500 | 5.25% of purchase price or NADA value, rounded to the nearest dollar |
A few important notes straight from the DMV notice:
The fee applies to the higher of the actual sale price or the NADA average trade-in value, so underpricing a bill of sale doesn't reduce what you owe.
Trade-ins can lower the taxable amount. Delaware allows a credit for the value of a Delaware-titled vehicle traded in during the same purchase, per the DMV's titling guidance.
Out-of-state buyers may get a credit for similar taxes already paid elsewhere, if the vehicle was titled in that state within 90 days, according to the same DMV fee page.
Once the bill of sale is signed and the title is transferred, the buyer still has work to do. Delaware law requires all buyers of Delaware-registered vehicles to apply for a new certificate of title "immediately following the purchase of the vehicle; but in no case, more than 30 days after the purchase," according to the Delaware DMV. Miss that window, and a penalty fee applies. Here's the general path for a private-party buyer:
Get Delaware liability insurance in place before visiting the DMV.
Complete a vehicle inspection, if required for the vehicle's age and history.
Bring the signed title, bill of sale, proof of insurance, and a valid Delaware driver's license.
Pay the document fee, title fee, and registration fee at a DMV service center.
Receive your new title and registration, typically the same day or by mail shortly after.

New residents bringing a vehicle from another state get a longer runway. They must title and register within 60 days of establishing Delaware residency, as outlined in the DMV's guide for new residents.
How Many Vehicles Are Registered in Delaware?
Delaware is a small state, but its vehicle count has been climbing steadily. The Delaware State Police Annual Traffic Statistical Report recorded 990,678 registered motor vehicles in 2024, up from 973,361 in 2022 and 967,400 in 2021. The same 2024 report counted 797,071 licensed drivers statewide.
That steady growth means more private sales, more title transfers, and more reasons to have paperwork that holds up if a dispute ever comes up.
Bill of Sale vs. Title: What's the Difference?
These two documents work together, but they're not interchangeable.
The title is the legal proof of ownership. It must be signed over by the seller and is required to register the vehicle.
The bill of sale is a record of the transaction itself: what was paid, when, and to whom.
The title moves ownership. The bill of sale documents the deal that led to it. Delaware's own title transfer page notes that the Division of Motor Vehicles recommends both parties appear together at a DMV office to complete the transfer, which limits errors on both fronts.
Tips for a Smooth Delaware Car Sale
A few habits go a long way toward avoiding delays:
Double-check the VIN on the bill of sale matches the title exactly.
Write the odometer reading in numbers, not an estimate.
Keep a copy of the signed bill of sale for your own records, even after the sale closes.
If the payment isn't happening in full at signing, spell out the balance due date clearly.
List your vehicle on a platform like KarKiosk if you want to reach buyers directly without dealer fees eating into your payout.
Common Mistakes to Avoid
Leaving the sale price blank or vague. This can trigger the DMV to use NADA trade-in value instead, which may be higher than what was actually paid.
Forgetting signatures from all listed owners. If a title has two names, both usually need to sign off.
Waiting past 30 days to register. This adds a penalty fee on top of the standard costs.
Not verifying the seller's identity matches the title. A mismatch can stall the whole transfer.
Final Thoughts
A Delaware bill of sale is a short document, but it carries real weight. It backs up the purchase price for the document fee, protects both sides if a disagreement comes up later, and keeps the title transfer moving without unnecessary trips back to the DMV. Pair it with a properly signed title, valid insurance, and a completed inspection, and the registration step becomes routine.
