Cosigner Liability on Auto Loans
When you cosign an auto loan, you're guaranteeing the full balance. If the primary borrower stops paying, the lender can pursue you for every missed payment, late fee, and the full remaining balance. Unlike a co-borrower, you typically have no ownership interest in the vehicle -- you're paying for a car you can't drive.
The lender doesn't have to pursue the primary borrower first. They can come directly to you the moment a payment is missed. Some lenders are more aggressive than others, but all have the legal right to hold you fully responsible.
Repossession and Deficiency Balances
If the car is repossessed, you might think your liability ends. It doesn't. After repossession, the lender sells the car (usually at auction for well below market value) and pursues both the borrower and cosigner for the deficiency balance -- the difference between the sale price and the loan balance, plus repossession costs and fees.
Example: Loan balance of $18,000. Car sold at auction for $10,000. Repossession, auction, and attorney fees of $3,000. Deficiency balance: $11,000. The cosigner is liable for this entire amount, on a car they never drove and that no longer exists. This deficiency can result in a default judgment and wage garnishment.
How to Protect Yourself as an Auto Loan Cosigner
Before cosigning: Insist on being added as a co-owner on the title (not just the loan). Set up loan payment alerts so you know immediately if a payment is missed. If payments stop: Make the payments yourself to protect your credit (you can seek reimbursement from the borrower later). If default is inevitable: A voluntary surrender is better than repossession (lower fees). Negotiate with the lender directly. Consider whether bankruptcy makes sense for the deficiency.
If you're already facing a deficiency balance, explore your options: negotiate a settlement (lenders often accept 40-60% of the deficiency), check whether the statute of limitations has run, or consider bankruptcy if the balance is large.
Frequently Asked Questions
If the car is repossessed, is my cosigner liability over?
No. You're liable for the deficiency balance -- the difference between the loan balance and the sale price, plus fees. Deficiency balances can be thousands of dollars. The lender can sue you and garnish your wages for this amount.
Can I take the car from the primary borrower if they stop paying?
Only if you're listed as a co-owner on the title. If you're just a cosigner on the loan but not on the title, you have no legal right to possess the vehicle. This is why you should insist on being added to the title before cosigning.
Should I make payments the borrower missed to protect my credit?
Making the payments protects your credit score and prevents default. You have a legal right to be reimbursed by the primary borrower (right of subrogation). Keep records of every payment you make. It's a difficult situation but late payments and default are worse for your credit.
