If someone asks you to serve as a cosigner for their car loan, you may have questions about the responsibilities you’d be taking on and what auto loan cosigner requirements you’d need to meet. In general, cosigners will need to have solid credit and be able to demonstrate proof of income and residency, along with other information, in order to back the primary borrower’s auto loan.
There are benefits as well as drawbacks to agreeing to assume this responsibility, and the primary borrower needs to consider the pros and cons as well. Read on for more on car loan cosigner requirements.
Key Points
• A cosigner can help an applicant get approved for an auto loan if they have a good credit score, sufficient income, and a low debt-to-income ratio.
• A cosigner, who becomes responsible for the debt, typically must submit proof of identity, income, and residency.
• Timely payments by the primary borrower can build their credit score; missed payments can harm both parties.
• Cosigning can strain relationships if the primary borrower defaults, but can build trust if obligations are met.
• Refinancing requires car details, insurance proof, and existing loan information, plus cosigner’s identity and income proof if applicable.
What Is an Auto Loan Cosigner?
An auto loan cosigner is someone (often a family member or good friend) who will sign loan papers to give a lender extra assurance that the person wishing to buy the car (the ‘primary borrower’) will make payments on time and repay the loan in full. If the borrower does not pay, then the cosigner is responsible for making payments on the auto loan.
The Role of a Car Loan Cosigner
A car loan cosigner can play a crucial role in helping someone else get a car loan finalized for approval. Sometimes, for example, the primary borrower hasn’t established enough credit yet or has too low a credit score for a car loan. In that case, a lender may require a cosigner so that someone else (with good credit) also has the responsibility of ensuring that payments are made. This can reduce the level of risk the financial institution is taking.
Or perhaps the primary borrower could get the car loan on their own but at a less than favorable interest rate rather than good interest rates. In that situation, a cosigner could help them secure a better rate and terms. That can help the primary borrower to have a lower principal and interest payment that can be easier for them to meet each month.
As payments are made on time, this can help the primary borrower build credit. For example, a parent may act as a cosigner to help their child secure their first car loan, then later drop off the loan once the child has built their credit.
The Cosigning Process
When a cosigner is used on a loan, their qualifications are checked alongside those of the borrower. Then, once the loan is approved, both parties (the primary borrower and the cosigner) will sign the loan agreement paperwork. The primary borrower is then expected to make payments on time but, if this doesn’t happen, then the cosigner is responsible for them.
Informed Agreement
According to the Federal Trade Commission, when you cosign a loan, the lender must provide a notice that details your obligations as a cosigner. This includes acknowledging that you’re being asked to guarantee repayment of the debt if the primary borrower does not. You may need to pay collection costs and other fees if this were to happen, and this information should be shared in the agreement as well.
Additionally, in some states, the lender can seek to collect the amount owed from the cosigner before going to the primary borrower, using the same collection techniques employed when trying to get payment from the main borrower. This may be included in the agreement if it applies in your state.

Pros and Cons of Using a Cosigner for a Car Loan
From a borrower’s perspective, there are advantages and disadvantages of using a cosigner:
| Pros of Using a Cosigner | Cons of Using a Cosigner |
|---|---|
| Having a qualified cosigner can be the difference between getting an auto loan application approved or rejected | If you miss payments, this can damage your cosigner’s credit (as well as your own) |
| You may get a lower interest rate (and, therefore, lower monthly payments) and better terms with a cosigner | If you fail to repay the loan, this can also harm your personal relationship with your cosigner |
From the perspective of being the cosigner, there are also pros and cons, including:
| Pros of Being a Cosigner | Cons of Being a Cosigner |
|---|---|
| You can help someone else secure a car loan, thereby helping them get transportation | You’re risking damage to your credit score if timely payments aren’t made |
| You can often assist them in getting a better interest rate and more favorable terms | If the primary borrower doesn’t make payments, then you’re liable to do so |
Auto Loan Cosigner Requirements
An auto loan cosigner should be someone who is creditworthy and has an appropriate income level, although specifics of what that means can vary by lender. One financial institution may require a higher credit score but not have as stringent of income requirements as another. Another may need to see a DTI, or debt-to-income ratio under 50%. To find out exactly what a particular lender’s car loan cosigner requirements are, be sure to ask and find out what documentation will be required for the cosigner.
If you’re a primary borrower who is applying for a car loan with cosigner requirements, be aware that not everyone will make a good cosigner. Cosigners can be family members or close friends — in other words, trustworthy people who are willing to help out.
Proof of Identity
The lender will want to see official documentation of the cosigner’s identity and will likely ask to see one or more of the following:
• Government-issued ID
• Passport
• Birth certificate
Government-Issued ID
A lender will almost certainly want you to present a photo ID that’s government-issued to verify your identity. This is typically a driver’s license but can also be a state-issued ID or a U.S. military identification card. The lender may also ask for your Social Security card.
Passport
If a lender requires you to show a passport and you don’t have one, this U.S. government site provides guidance on obtaining one.
Birth Certificate
If you don’t have a copy of your birth certificate and you were born in the United States, you can contact the vital records office in your state to request one. If you need to get one quickly in order to cosign a loan, ask about expedited service options.
Proof of Income
In addition to collecting identifying documents, cosigner requirements for a car loan will usually include providing proof of income. Documents that may be used include:
• Pay stubs
• Bank statements
• Wages and tax statements
Pay Stubs
This is a common way for a lender to verify your current income. So, if you plan to cosign for someone, make sure to keep yours. This can be easier if they’re provided online. If needed, you could ask your employer for copies.
Bank Statements
A lender may also ask to see copies of your bank statements. This will show the money you have coming in as well as what’s going out. If your paychecks are automatically deposited via direct deposit, this can act as double duty (although this would demonstrate net income rather than gross).
Wages and Tax Statements
Tax returns can show the bigger picture of your income. As such, lenders may ask to see a couple of years of returns to determine the steadiness of your income. If you’re self-employed, you won’t have pay stubs, so tax returns, along with other financial statements, may be required.

Creditworthy History
A lender’s auto loan cosigner requirements may include a hard inquiry into the cosigner’s credit report. A lender may or may not have a specific credit score that’s required, but they typically want to see one that’s very good, even excellent. This may mean a score of 660 or above.
Again, consult your lender of choice for more specifics on what’s required credit-wise.
Proof of Residence
The lender may also want proof of where you live. Acceptable examples can include the following documents, among others:
• Utility bill
• Government-issued ID
• Property tax bill
Utility Bills
These are often used as proof of residency because they demonstrate that you’re paying to keep the heat and lights on at a particular address.
Government-Issued ID
A lender may look at your government-issued ID and double check it against the utility bill or other proof of residence to make sure that the addresses match.
Property Tax Bills
Property tax bills can demonstrate that you’re paying taxes on a property and, when it matches the address on your government-issued ID, can often be enough proof of residency for a lender.

Do I Need Any Additional Documents to Refinance My Car Loan With a Cosigner?
If you decide to refinance a car loan with a cosigner to reap some of the perks of refinancing your car, you’ll need to provide the same information as you would with a purchase. You may also need to provide the following details about your vehicle:
• Car make and model
• Car year
• Mileage on the odometer
• Vehicle identification number (VIN)
You may also need proof of car insurance and information about your existing loan to refinance a car loan with a cosigner. While you’re researching your refinancing options, you may also ask the lender about their car refinancing time frame to make sure it aligns with what you want or need.
A primary borrower also may decide to refinance their auto loan to remove a cosigner from the loan. Perhaps the original car loan required a cosigner because the primary borrower still needed to build up their credit. Or maybe the borrower didn’t earn enough income yet to support the loan.
If any of these circumstances have changed, then it may be possible to refinance without a cosigner, in which case you’d need much of the same information outlined above (minus that of a cosigner). Other factors may come into play. For example, it can be difficult to refinance a high-mileage vehicle but not necessarily impossible.

The Takeaway
Plenty of good reasons exist for a borrower to get a cosigner, such as helping to positively impact your approval odds. However, there are pros and cons, both for the primary borrower and for the cosigner. These need to be carefully weighed before moving ahead. At some point, it can make sense to refinance the car loan, either with or without a cosigner.
