The role of an auto loan co-signer is to provide the lender with extra assurance that the loan will be paid. However, it’s natural to wonder about any additional obligations when you need a co-signer for a car loan. There are two different questions you may be considering: “Does a co-signer have to be on an insurance policy?” and “Can you co-sign for car insurance?”

Here we’ll take a look at both questions and consider some additional information about insurance with a co-signer.
- Co-signers only share ownership if their name is on the title
- Anyone listed on the title can be held liable for an accident
- Any regular driver of a vehicle can be added to the auto insurance policy
Car Co-Signer Requirements
Does a co-signer have to be on car insurance? No, the co-signer on a car loan is not legally obligated to be on the auto insurance policy. Only those who actually drive the vehicle are required to be on the insurance policy. Anyone listed as a driver on your insurance policy is covered in the event of an accident, but you won’t need this coverage for your co-signer if they don’t drive your vehicle.
So, what is a co-signer responsible for? The co-signer’s responsibility is to ensure the loan is paid if the vehicle owner fails to make the payments. Beyond this, a co-signer is not responsible for car insurance, registration, or any other process involving the vehicle.
However, it’s often a good idea to list the co-signer on the car insurance policy under certain conditions. Let’s find out when does a co-signer have to be on car insurance.
Co-signers Who are Also Co-owners
A co-signer only has their name on the loan but none of the vehicle’s other documentation, such as title or registration. However, if the co-signer is also listed on the vehicle’s title, they are more than just a co-signer — they are a co-owner.
When a co-signer is a co-owner, it’s wise to have both co-owners listed on the car insurance policy. In the event of an accident, the vehicle’s owner(s) may both be considered liable, regardless of who is driving. For this reason, consider adding a co-signer to an auto insurance policy when they are also a co-owner of the vehicle.
Co-Signers Who Also Drive the Vehicle
Another situation when a co-signer can put insurance in their name is if they drive the vehicle. If anyone other than the vehicle owner is a regular driver of the car, then they should be included in the policy to avoid liability issues. This includes co-signers, as it’s fairly typical for a co-signer to drive the vehicle they co-sign for.
Co-Signing for Car Insurance
There is no co-signer on a car insurance policy. Co-signing is a term that is strictly related to the loan used to purchase the vehicle. So, what is a co-signer for a car? A co-signer for a car, often referred to as a co-borrower, is involved in the car-buying process but does not necessarily hold any ownership over the vehicle.
However, adding the co-signer as a driver on the insurance policy has possible financial benefits. For example, if the vehicle owner is a high-risk driver, adding the co-signer to the car insurance policy could reduce your insurance rates.
Co-Signer vs Co-Borrower in an Auto Loan
A co-signer is someone who agrees to take on the responsibility of repaying the loan if the primary borrower fails to do so. A co-borrower, on the other hand, is equally responsible for repaying the loan and shares ownership of the vehicle. Unlike a co-signer, a co-borrower’s name appears on the loan agreement and the vehicle title.
If You Co-sign For a Car, Do You Have to be on the Insurance
No, including the co-signer on an insurance policy is not required but often recommended. The co-signer’s obligation is only to the vehicle’s loan, so they are not required to be on an insurance policy. However, it’s often a good choice to add them anyway if they’re also the vehicle’s co-owner or if they regularly drive the vehicle.
Adding the co-borrower as a second driver on the policy can also help reduce monthly rates, but car insurance quotes will vary depending on each driver’s history.

Frequently Asked Questions
Can you get a co-signer for car insurance?
The co-signer requirements for car insurance can vary depending on the insurance company and the specific circumstances. In most cases, co-signers are not automatically required to be listed on the policy. However, it is important to notify the insurance company about the presence of a co-signer to ensure proper coverage and compliance with the policy terms. It’s advisable to check with your insurance provider to understand their specific requirements regarding co-signers.
Why would a co-signer need to be on the auto insurance policy?
While it may not be mandatory for co-signers to be on the auto insurance policy, there are situations where it is recommended or required. Some reasons why a co-signer might need to be included on the policy include:
- Ownership: If the co-signer is also a co-owner of the vehicle, it is generally advisable for them to be listed on the policy to ensure that they have the necessary coverage in case of an accident or damage.
- Financial Responsibility: In certain cases, lenders or financial institutions may require the co-signer to be listed on the insurance policy to ensure that the vehicle is adequately insured. This helps protect their investment in the event of an accident.
- Liability Coverage: Including a co-signer on the policy can provide an additional layer of liability coverage. This can be important if the co-signer may have financial exposure in case of an accident or if they are using the vehicle regularly.
What information is needed to add a co-signer to an auto insurance policy?
When adding a co-signer to an auto insurance policy, you will typically need to provide the insurance company with the co-signer’s basic information, such as their name, date of birth, contact details, and relationship to the primary policyholder. Additionally, the insurance company may request additional information, such as the co-signer’s driver’s license number or social security number, to properly identify and assess the risk associated with the policy.
Can a co-signer affect the cost of auto insurance?
Yes, the inclusion of a co-signer on an auto insurance policy can potentially impact the cost of insurance. Insurance companies consider various factors when calculating premiums, including the driving records and insurance histories of all individuals listed on the policy. If the co-signer has a poor driving record or a history of accidents, it could result in higher premiums for the policy. On the other hand, if the co-signer has a clean driving record and a good insurance history, it may have a positive effect on the cost of insurance.
What happens if a co-signer is not listed on the auto insurance policy?
If a co-signer is not listed on the auto insurance policy when they should be, it can potentially create issues in the event of an accident or a claim. Insurance policies typically have terms and conditions that require all individuals who have an ownership interest in the vehicle or who regularly use it to be listed on the policy. Failing to include a necessary co-signer could result in denied claims or insufficient coverage, leaving both the policyholder and the co-signer financially vulnerable. It is important to inform the insurance company about the co-signer and update the policy accordingly to ensure proper coverage.
Can a co-signer be removed from the auto insurance policy?
Whether a co-signer can be removed from an auto insurance policy depends on the specific circumstances and the policies of the insurance company. Generally, if the co-signer is also a co-owner of the vehicle, their removal from the policy may require transferring ownership or refinancing the loan.
A co-signer can be removed from a car lease when they’re not the owner but were added to the policy for liability or other reasons. Their removal may be possible by contacting the insurance company and requesting the change. It’s important to consult with the insurance provider directly to understand their procedures and requirements for removing a co-signer from the policy.
Can a co-signer insure the car?
A co-signer can insure the car, however, the primary owner of the vehicle must be listed on the insurance policy. When you have an auto loan with a co-signer, the co-signer’s role is primarily to guarantee the loan or lease payments and not necessarily to be the primary insured party.
Do I need a co-signer for a car lease?
If you’re wondering “Do I need a co-signer for a car loan?”, you should know that it depends on factors such as your credit history, income, and the leasing company’s requirements. If you have a strong credit history and sufficient income to qualify for the lease on your own, you may not need a co-signer.
Who can be a co-signer for a car lease?
A co-signer for a car lease or loan is typically someone with a strong credit history and sufficient income to qualify for the loan or lease on their own. This could be a family member, friend, or anyone else willing to take on the financial responsibility of guaranteeing the payments.
