Cosigner
Quick Definition
A person who agrees to repay a loan if the primary borrower defaults, sharing legal responsibility for the debt.
Key Takeaways
- Cosigners are equally liable for the full loan amount including interest and fees
- The loan appears on both the borrower's and cosigner's credit reports
- Some loans offer cosigner release after a period of on-time payments
- Cosigning can reduce the cosigner's borrowing capacity for their own needs
What Is Cosigner?
A cosigner is an individual who signs a loan agreement alongside the primary borrower, guaranteeing repayment if the borrower cannot meet their obligations. Cosigning is common for borrowers with limited credit history, low credit scores, or insufficient income to qualify independently. The cosigner's creditworthiness helps the primary borrower obtain approval and potentially better terms. However, cosigning carries significant risk: the cosigner is equally liable for the full debt, the loan appears on their credit report, and any missed payments damage both parties' credit scores. Financial advisors generally caution against cosigning unless the cosigner can comfortably afford the payments.
Cosigner Example
- 1A parent cosigns their child's first auto loan because the 19-year-old has no established credit history.
- 2A cosigner with a 780 credit score helps a friend qualify for an apartment lease that requires a minimum 700 score.
- 3After the primary borrower defaults on a $30,000 student loan, the cosigner becomes responsible for the remaining balance plus accrued interest.
