What is a co-signer?

• A. The loan officer
• B. A loan insurer
• C. The loan's guarantor's cousin
• D. Another adult who takes responsibility for your debt if you cannot afford it

Answer: (D)

A co-signer is someone who signs a loan with you and becomes legally responsible for repaying the debt if you can’t. That means their credit and finances are on the line just like yours, and they must step in to make payments if you miss them. Lenders use a co-signer to reduce risk when the borrower doesn’t have enough credit history or income. The other options don’t fit because a loan officer processes the loan, not guarantees repayment; a loan insurer provides insurance rather than a person who signs to guarantee the loan; and while a relative could be a co-signer, the defining idea is the promise to take on the debt if you can’t pay, not a specific relationship.
