Getting a co-signer can make it easier to get approved for a car loan, especially if you have limited credit history, bad credit, or don't meet a lender's requirements on your own.
But what happens if your situation changes?
Maybe your co-signer no longer wants to be responsible for the loan. Maybe your relationship has changed, or you've improved your credit and no longer need their help. You may be wondering: can you switch co-signers on a car loan?
The short answer is that it can be possible, but you generally can't simply remove one person from an existing loan and replace them with someone else. The lender will need to approve the change, and in many cases, refinancing the vehicle may be the most practical solution.
What Is a Co-Signer on a Car Loan?
A co-signer is someone who agrees to share responsibility for a loan with the primary borrower.
When someone co-signs a car loan, they're telling the lender that they will help repay the debt if the primary borrower can't make the required payments.
A co-signer can be helpful when a borrower has:
- Limited credit history
- No established credit
- Bad credit
- Low income
- A recent bankruptcy or consumer proposal
Having a financially strong co-signer can give a lender additional confidence when reviewing the application.
It's important to understand that co-signing is a serious financial commitment. If the primary borrower misses payments, the co-signer can also be responsible for the debt, and missed payments may affect their credit.
Can You Change a Co-Signer on a Car Loan?
Generally, you cannot simply ask the lender to erase one co-signer's name and replace it with another.
The original loan agreement was approved based on the financial information and credit history of the people who signed it. Changing one of those borrowers changes the lender's risk.
Because of this, the lender will need to review the situation and determine whether they are willing to approve the change.
Some lenders may have procedures that allow a co-signer to be released under certain circumstances. Others may require the existing loan to be paid off and replaced with a new loan.

Why Would Someone Want to Switch Co-Signers?
There are several reasons you might want to change a co-signer.
Your Relationship Has Changed
A common reason is a change in the relationship between the borrower and co-signer.
For example, a family member or former partner may no longer want to remain financially responsible for the vehicle.
Your Co-Signer's Financial Situation Has Changed
If your co-signer has taken on new debt, lost income, or experienced another financial change, they may no longer want to remain on the loan.
You've Improved Your Credit
If you've made consistent payments and improved your credit since taking out the original loan, you may no longer need the same co-signer.
In this situation, refinancing the loan on your own could be an option.
You Want a Different Co-Signer
You may also have someone else who is willing to co-sign and who has a stronger financial profile.
However, simply finding a new co-signer doesn't mean the lender will automatically approve the change.
How Can You Switch Co-Signers?
If you're trying to change co-signers, there are a few options worth exploring.
1. Contact Your Current Lender
Your first step should be contacting the lender that currently holds your car loan.
Ask whether they offer a co-signer release or replacement option and what requirements need to be met.
Some lenders may allow a co-signer to be removed if the primary borrower can now qualify independently.
2. Apply to Remove the Existing Co-Signer
If the lender allows it, you may need to submit updated financial information.
The lender could review:
- Your income
- Employment
- Credit score
- Existing debt
- Payment history
- Remaining loan balance
If your financial situation has improved significantly, you may be able to qualify without a co-signer.

3. Consider Refinancing
If your existing lender won't allow you to change the co-signer, refinancing may provide another option.
Refinancing involves taking out a new car loan to pay off your existing loan. The new loan can potentially have a different borrower structure, meaning you may be able to remove the original co-signer or add someone else.
Refinancing may also make sense if your credit has improved since you originally financed the vehicle.
If you think you may qualify for better financing, you can apply for a car loan with Car Loans Canada to explore your options.
Can You Remove a Co-Signer Without Refinancing?
Sometimes, but it depends entirely on the lender.
Some lenders may allow a co-signer to be released after the primary borrower has demonstrated a strong payment history and can qualify independently.
Others won't modify the original agreement.
If your lender doesn't offer a release option, refinancing is usually the most straightforward alternative.
Will Switching Co-Signers Affect Your Credit?
Potentially.
If you refinance the car, the new lender will generally review the borrower's credit and financial information. This may involve a hard credit inquiry.
The existing loan will also be paid off and replaced with a new account.
If you're considering refinancing, make sure the new loan actually improves your financial situation. A lower monthly payment isn't necessarily better if it comes with a significantly longer term or higher total interest costs.

What If Your Co-Signer Wants Off the Loan?
If your co-signer no longer wants to be responsible for your car loan, don't ignore the situation.
Start by contacting your lender and asking whether a co-signer release is available.
If you can't qualify on your own, you may need to explore refinancing with another lender or consider whether replacing the co-signer is possible.
It's important to remember that your co-signer generally can't simply remove themselves from the loan without the lender's approval.
Frequently Asked Questions
Can I replace my co-signer with someone else?
Possibly. The lender will need to approve the new co-signer and may require a new credit application. Some lenders may instead require you to refinance the vehicle.
Can I remove a co-signer from my car loan?
Sometimes. If your lender offers a co-signer release and you can qualify for the loan independently, you may be able to remove them without refinancing.
Does refinancing remove the old co-signer?
It can. When you refinance a car loan, the original loan is paid off and replaced with a new loan. The new loan can potentially be structured without the original co-signer, assuming you qualify.
Can I refinance my car loan if I have bad credit?
It depends on your financial situation and the lender's requirements. Factors such as your payment history, income, current credit score, and remaining loan balance can all affect your options.
The Bottom Line
Switching co-signers on a car loan isn't as simple as changing a name on an agreement. Your lender needs to approve any change, and the new co-signer will likely have to meet the lender's credit and financial requirements.
If your credit has improved since you originally financed your vehicle, you may be able to remove your co-signer by refinancing the loan in your own name. If you need a new co-signer, refinancing may also allow you to restructure the loan with someone else.
