Thinking About Being a Co-Borrower or Co-Signer? Here’s What You Need to Know

Jennifer Hernandez • November 13, 2024


If someone close to you has asked you to be a co-borrower or a co-signer on a loan, you might have a lot of questions about what that really means. These requests often come from family members or friends who need help qualifying for a loan, and it's important to fully understand the responsibilities, risks, and potential impacts before agreeing. Let’s talk about some of the most common questions about being a co-borrower or co-signer so you can make an informed decision.


What Is a Co-Signer

A co-signer is someone with good credit and a stable income who agrees to back a loan for a borrower who may not qualify on their own. Co-signers are typically family members or close friends who are comfortable assuming some level of financial responsibility.


Key Responsibilities of a Co-Signer:

  • Financial Backup: If the primary borrower can't make payments, you agree to cover the debt.
  • No Ownership Rights: While you're legally responsible for the loan, you don’t have any ownership stake in the asset (e.g., a car or house).
  • Credit Impact: Late or missed payments will negatively impact both your and the primary borrower's credit scores.


What Is a Co-Borrower?


A co-borrower is someone who applies for a loan jointly with the primary borrower. As a co-borrower, you share both ownership of the asset and responsibility for repaying the loan. This arrangement is common among spouses, business partners, or close family members.


Key Responsibilities of a Co-Borrower:

  • Shared Ownership: You’ll likely be listed on the title of the asset (such as a home or car), meaning you share ownership of the property.
  • Equal Responsibility: Both you and the primary borrower are equally responsible for repaying the loan.
  • More Involved Commitment: Your financial background, including your income and credit, will be assessed alongside the primary borrower’s when applying for the loan.

 Benefits of Being a Co-Signer or Co-Borrower:

Being a co-signer or co-borrower is a significant commitment that can have both personal and financial benefits, especially when helping a loved one with a major purchase, like a car or home, or securing a loan for education. Co-signers play a key support role by helping a primary borrower qualify for a loan, while co-borrowers typically have a shared ownership stake. Here are some benefits:

  • Credit Building: If the primary borrower makes payments on time, your credit score can benefit from the positive repayment history.
  • Asset Growth: Co-borrowers gain part ownership, which can build wealth for both parties if the asset appreciates.
  • Supportive Role: Whether you’re co-signing or co-borrowing, you’re helping someone achieve important financial milestones.

How Does Co-Signing or Co-Borrowing affect my credit?


Both co-signing and co-borrowing affect your credit score and borrowing power. As a co-signer, the loan shows up on your credit report and adds to your debt-to-income ratio, which lenders review when evaluating your creditworthiness. Consider these potential effects:

  • Positive or Negative Impact: Consistent, timely payments can boost your credit score, while missed payments will have a negative impact.
  • Debt-to-Income Ratio: Any co-signed or co-borrowed loan counts toward your financial obligations, which may limit your ability to obtain new credit.
  • Shared Responsibility: Co-borrowers, in particular, share responsibility for payments, with any missed payments affecting both credit scores.

What to Consider If Payments Aren't Made


If a primary borrower stops making payments, both co-signers and co-borrowers bear responsibility for the loan, which can lead to serious financial consequences. Additionally, the roles of co-signers and co-borrowers differ when it comes to ownership:

  • Default Risks: Missed payments may lead to collections and a hit to your credit score.
  • Ownership Rights: Co-signers are not on the title or ownership papers, but co-borrowers are usually listed as co-owners.
  • Exiting the Loan: Both co-signers and co-borrowers may need to refinance to remove themselves from a loan, which often requires credit approval from the primary borrower.


Should You Co-Sign or Co-Borrow?


Being a co-signer or co-borrower is a significant responsibility that can have lasting financial consequences. If you trust the primary borrower and feel confident in their ability to repay the loan, it can be a valuable way to support someone you care about. However, it’s essential to weigh the risks and understand the potential impact on your credit score and financial future.

Before making a decision, consider having an honest conversation with the borrower about payment expectations and discussing contingency plans. Being financially supportive is generous, but it’s crucial to protect your own financial health in the process. For more on deciding between being a co-signer or co-borrower, read our full guide.
