Can the Co-signer Refinance an Auto Loan?

If you have bad credit or a limited credit history, you may need a co-signer to secure an auto loan. A co-signer is someone who agrees to share responsibility for the loan with you and help you qualify for a better interest rate or loan terms. The answer to this question is yes, but depends on several things, including the terms of your original loan and the willingness of your co-signer to take on the responsibility of refinancing the loan.

The Basics of Refinancing

Refinancing is the process of replacing an existing loan with a new loan that ideally has more favorable terms. When it comes to auto loans, refinancing can be a smart move if you can secure a lower interest rate, lower monthly payments, or better loan terms. A co-signer can help you qualify for a better auto loan refinancing offer if you have less-than-perfect credit. However, there are also additional fees associated with refinancing, and co-signing a loan means that both you and the co-signer will be responsible for the loan. It's important to weigh the pros and cons before deciding whether refinancing with a co-signer is right for you.

Ending a Co-signed Auto Loan

Ending a co-signed auto loan most often happens by paying off the loan in full and thus removing the co-signer's responsibility for the debt. Another option, if allowed per the loan contract, is applying for a co-signer release to have the person's name taken off the loan agreement. This is typically done when the primary borrower has established good credit and can qualify for a loan on their own, or when the co-signer wants freedom from their financial obligation or to purchase a vehicle of their own. It's important to note that ending a co-signed auto loan isn't the same as refinancing with a co-signer, as the latter option still involves both parties being responsible for the loan.

Things to Consider before the Co-signer Refinances

If you're considering co-signer refinancing for your auto loan, it's important to weigh the potential benefits and drawbacks. Here are several things to consider before moving forward:

  • Co-signer responsibility: When you refinance your auto loan with a co-signer, both you and the co-signer are responsible for repaying the loan. This means that if you're unable to make payments, the co-signer is liable. Before you proceed with co-signer refinancing, ensure that both you and the co-signer understand the responsibilities involved.

  • Credit score impact: Refinancing your auto loan can have a positive impact on your credit score if you're able to secure a lower interest rate for faster debt payoff and you make timely payments. However, if you have a co-signer, your loan may also impact their credit score. Late or missed payments can negatively impact both of your credit scores.

  • Additional fees: Refinancing an auto loan often involves additional fees, such as application fees, processing fees, and possibly even prepayment penalties. These fees can add up quickly and may negate any savings you may have gained from refinancing.

  • Loan terms: Before refinancing your auto loan with a co-signer, carefully review the new loan terms. Ensure that the interest rate, monthly payments, and repayment period are favorable and will help you meet your financial goals.

  • Co-signer qualifications: Co-signers typically need to meet certain qualifications to be eligible to co-sign a loan, such as having a good credit score and stable income. Before you ask someone to co-sign your loan, ensure they meet these qualifications and are willing to take on the responsibility of co-signing.

What Co-signers Need to Do before Refinancing

Refinancing an auto loan with a co-signer can be a smart move, but it's important to take certain steps before applying. Here are a few things co-signers should do before refinancing an auto loan:

  • Review credit reports: Before refinancing, co-signers should review their credit reports to ensure they are accurate and current. Dispute any errors and correct them before applying for a new loan.

  • Determine eligibility: Co-signers should check their credit score to determine if they meet the lender's eligibility requirements. If their credit score has improved since the initial loan, they may be able to qualify for a better interest rate. They should also make sure they have enough income to meet the lender's requirements and be able to afford loan payments if the primary borrower falls behind.

  • Gather documents: Co-signers will need to gather documentation, such as proof of income and employment, to support their loan application. They should also have the original auto loan documents on hand.

  • Research lenders: Co-signers should research potential lenders and compare interest rates and fees. They should also read reviews and check the lender's reputation with the Better Business Bureau.

  • Communicate with the borrower: Co-signers should discuss the refinancing process with the borrower and ensure they understand the terms and obligations of the new loan. They should also ensure the borrower is aware of any changes to the payment schedule or terms.

Pros and Cons of Having a Co-signer Refinance a Loan

Having the co-signer refinance a loan can be a beneficial move in the right situation, but it also comes with some potential drawbacks. Consider these examples before proceeding:


  • Improved loan terms: One of the primary benefits of having a co-signer for refinancing is the potential for improved loan terms. With a co-signer, you can often secure a lower interest rate, longer repayment term, or other favorable loan terms that you might not qualify for on your own.

  • Improved credit score: Making timely payments on your refinanced loan with a co-signer can help improve your credit score over time, which can benefit you in other areas of your financial life.

  • Shared responsibility: With a co-signer, you share responsibility for the loan, which can be beneficial if you're struggling to make payments or need someone to help you manage your finances.


  • Co-signer risk: Co-signing a loan comes with risks, as the co-signer is also responsible for repaying the loan. If you default on the loan or miss payments, it can negatively impact the co-signer's credit score and financial standing.

  • Personal relationship strain: Refinancing a loan with a co-signer can also strain personal relationships if there are any disagreements or misunderstandings about the loan terms or repayment responsibilities.

  • Limited financial flexibility: With a co-signed loan, you may have limited financial flexibility, as you'll need to consider the co-signer's financial situation and repayment responsibilities before making any changes to the loan.

How to Avoid Using a Co-signer for Refinancing

Using a co-signer for refinancing isn't always the best option. Here are some steps you can take to potentially avoid the need for a co-signer refinance:

  • Improve your credit score: Having a good credit score is the most important factor in securing a favorable refinancing deal. If you have a poor credit score, work on improving it before applying for a refinancing loan. You can do this by paying your bills on time, keeping your credit card balances low, and disputing any errors on your credit report.

  • Shop around: It's important to shop around for the best refinancing deals. Check with various lenders, including online lenders and credit unions, to find the best rates and terms.

  • Consider a co-signer release: If you currently have a co-signer on your auto loan, consider requesting a co-signer release. This will allow you to remove the co-signer from the loan and refinance on your own.

  • Negotiate with your current lender: If you have been making timely payments on your auto loan, your current lender may be willing to work with you to refinance the loan without a co-signer. Contact your lender and ask if they have any refinancing options that don't require a co-signer.

  • Pay down your debt: Reducing your debt can also improve your chances of refinancing without a co-signer. Paying down your credit card balances and other debts can improve your debt-to-income ratio, making you a more attractive candidate for refinancing.

Where to Find Refinancing Loans with a Co-signer

If you've decided to allow your co-signer to refinance your vehicle loan, you have several options. Here's where you can potentially find financing packages:

  • Banks and credit unions: Many traditional banks and credit unions offer auto loan refinancing options that allow co-signers. Contact your local bank or credit union to find out their specific requirements for co-signers.

  • Online lenders: Many online lenders specialize in auto loan refinancing, and some offer the option to add a co-signer to the loan. Research the lender thoroughly before applying and check their interest rates and fees.

  • Dealer financing: Some car dealerships may offer refinancing options that allow for a co-signer. However, dealership financing may have higher interest rates and fees than other lenders.

  • Referral services: Several online referral services available can help you find a lender that offers auto loan refinancing with a co-signer. These services often provide multiple options for comparison.

The Bottom Line

In conclusion, refinancing an auto loan with a co-signer can be a helpful option for those looking to lower their monthly payments and secure better loan terms. However, it's still important to consider the potential drawbacks, such as additional fees and the co-signer's responsibility for the loan. Before deciding to refinance with a co-signer, take the necessary steps to prepare, such as reviewing your credit score and researching potential lenders.

If you decide that co-signer refinancing isn't the right option, there are alternative strategies to consider, such as improving your credit score or negotiating with your current lender. Ultimately, the best decision will depend on your unique financial situation and goals.
