To fill out a borrowed car agreement, write in the full legal names and license numbers of the owner and borrower, describe the vehicle by year, make, model, VIN, and plate, set exact start and end dates, spell out who pays for fuel, tolls, and tickets, note the car’s condition and odometer reading, then have both parties sign and date it. The whole process takes about ten minutes if the information is gathered first, and the finished document gives the owner proof they authorized the use and the borrower proof they are not driving a stolen car.
Gather the Information First
Chasing down a policy number or plate number mid-signing invites transcription errors. Pull everything together before you open the form.
- Full legal names of both parties, exactly as they appear on government-issued ID. A nickname can create problems if the agreement is ever used as evidence of authorized possession.
- The borrower’s driver’s license number and issuing state. If the borrower holds a foreign license, check whether the state where the car will be driven requires an International Driving Permit, which must be obtained before arrival in the U.S.1USAGov. Driving in the U.S. if You Are Not a Citizen
- Vehicle year, make, model, color, and the 17-character VIN. The VIN is visible through the lower-left corner of the windshield and is printed on the registration card. Federal regulations require every VIN to be exactly 17 characters mixing letters and digits.2GovInfo. 49 CFR Part 565 – Vehicle Identification Number Requirements
- License plate number. Toll authorities and law enforcement identify vehicles by plate rather than VIN.
- The owner’s insurance carrier name and policy number. The borrower will need this if they are stopped or in an accident.
Verify every number against the physical registration card and insurance card. A single transposed digit in the VIN or policy number can turn the agreement into a document about the wrong car or the wrong coverage.
Fill In the Parties and Vehicle Blocks
Most templates follow the same layout: parties at the top, vehicle in the middle, terms at the bottom.
In the party fields, enter each person’s full legal name, driver’s license number, and state of issuance. If the form has fields for mailing address and phone number, fill them in; they help if either side needs to reach the other during the loan.
In the vehicle block, enter the year, make, model, color, VIN, and plate number. If there is an odometer field, record the current mileage. That number matters later if the agreement includes a mileage cap or if a dispute arises about how far the car was driven. Write legibly, or use a digital form. One unclear character in a handwritten VIN makes the entire vehicle description ambiguous.
Write the Terms Clearly
The terms section is where the agreement does its real work. Vague language defeats the purpose of putting anything in writing.
Loan Period
Specify the exact start date, start time, end date, and end time. “A few days” invites disagreement. A clear deadline gives the owner grounds to treat continued possession as unauthorized if the borrower keeps the car past the return time. Professional borrowed vehicle agreements typically also require the car to be returned on demand if the owner needs it back early.3Ryan Specialty. Dealer Protect Borrowed Vehicle Agreement
Where and How the Car Can Be Used
State whether the borrower can take the car out of the local area, across state lines, or only within a defined radius. Insurance coverage can vary by state, and some policies carry territorial limits. You can also restrict specific uses: no off-road driving, no towing, no ride-share or delivery work. If the car is driven commercially without proper coverage, the owner’s personal auto policy will almost certainly deny any resulting claim.
Who Pays for What
Assign responsibility for fuel, tolls, and parking. The standard approach is that the borrower pays for all fuel used and any tolls or parking fees incurred during the loan.
The clause that gets forgotten is the one about tickets. State clearly that the borrower is responsible for any traffic or parking fines resulting from violations committed while they have the car. Without this clause, the owner receives the tickets as the registered vehicle owner and has to chase the borrower for reimbursement.
Prohibited Conduct
Common restrictions include no smoking in the vehicle, no transporting pets, no driving under the influence of alcohol or drugs, and no allowing anyone other than the named borrower to drive the car.3Ryan Specialty. Dealer Protect Borrowed Vehicle Agreement The last restriction matters more than people realize. If the borrower hands the keys to a third person and that person causes an accident, the insurance and liability picture gets significantly more complicated.
Accident Reporting
Require the borrower to notify the owner within a set window after any accident, no matter how minor. Twelve hours is typical.3Ryan Specialty. Dealer Protect Borrowed Vehicle Agreement The notice should include the other driver’s information, a description of the damage, and a police report number if one was filed. Delayed reporting can complicate or jeopardize an insurance claim.
Document the Condition at Handoff
An agreement that says the car was in “good condition” is nearly useless if the borrower returns it with a dented fender and claims the dent was already there. Five minutes of documentation prevents that argument.
Walk around the car together. Note any existing scratches, dents, chips, stains, or cracked glass directly on the agreement or on an attached sheet. Record the current odometer reading. Take timestamped photos of all four sides, the dashboard, and any pre-existing damage. Both parties should keep copies of the photos.
Some professional loaner agreements go further, having the borrower acknowledge receiving the vehicle in satisfactory mechanical condition and accept responsibility for repair costs during the loan regardless of fault.3Ryan Specialty. Dealer Protect Borrowed Vehicle Agreement For a loan between friends or family that level is usually overkill, but at a minimum both parties should agree in writing on what the car looked like when it changed hands.
Confirm the Insurance Situation Before You Sign
Before the owner hands over the keys, it helps to know how coverage actually works, because many owners assume incorrectly. Auto insurance generally follows the car rather than the driver. If you lend your car and the borrower causes an accident, your policy is the primary coverage and pays first, up to your limits, as if you had been driving. If damages exceed your limits, the borrower’s own policy may pay the remainder as secondary coverage.4Nationwide. Does Car Insurance Follow the Car or the Driver Your premiums are still the ones at risk after a claim.
Two scenarios can shrink or erase coverage. If the borrower is listed as an excluded driver on your policy, the insurer will deny the claim outright; written permission from you does not override the exclusion.5Progressive. What Is an Excluded Driver Some policies also contain a step-down provision that reduces coverage for permissive-use drivers to the state minimum, even if the owner carries higher limits personally.
Call your insurer before lending the car and confirm the borrower is not excluded and whether the policy contains a step-down provision. Noting the insurer’s answer in the agreement or in your own records creates a paper trail if anything is disputed later.
A written agreement that records the borrower’s valid license number also helps the owner show basic due diligence. It does not provide immunity, but it undercuts any later claim that the owner handed the keys to someone obviously unfit to drive.
Sign and Date the Agreement
Both the owner and borrower sign and date the agreement. The date next to each signature establishes when the contract took effect, and it should match the loan start date in the terms section. If those dates do not line up, the discrepancy can create confusion about when the borrower’s obligations actually began.
Notarization
Notarization is not legally required for a borrowed car agreement in any state, but having a notary witness the signatures adds credibility. The notary verifies each signer’s identity through government-issued ID and stamps the document, which makes it harder for either party to later claim they did not sign. Notary fees for a single acknowledgment are modest, typically in the range of a few dollars to $15 depending on the state.
Electronic Signatures
If the owner and borrower are not in the same place, a digitally signed agreement is legally valid. Under the federal ESIGN Act, an electronic signature carries the same legal weight as a handwritten one, and a contract cannot be denied enforceability solely because it was formed electronically.6Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity For the signature to hold up, both parties must clearly intend to sign, consent to transacting electronically, and the platform must retain a record that can be accurately reproduced. Standard e-signature services handle these requirements automatically.
After Signing
Print or save two identical copies. The owner keeps one. The borrower keeps the other inside the vehicle, in the glove compartment alongside the registration and insurance cards. If the borrower is stopped by police or passes through a checkpoint, that copy is immediate proof of permission to drive the car. Without it, an officer has no quick way to distinguish an authorized borrower from someone who took the car without permission, and the stop can escalate to a vehicle hold or impoundment.
When the car comes back, do another walk-around and compare the current condition against the handoff documentation. Record the ending odometer reading and confirm it falls within any mileage cap in the agreement. If there is new damage, the pre-loan photos and the signed terms make the conversation about responsibility straightforward. Once both sides are satisfied, the owner can note the return date and time on their copy for the record.
