Yes, someone can cosign a credit card, but the practical answer is that very few issuers still allow it. After the Credit CARD Act of 2009, most major national banks dropped cosigning entirely and now offer an authorized-user arrangement instead. If you want a cosigned credit card today, you’ll generally need to look at credit unions and smaller regional banks, and the person who signs on takes full legal responsibility for the balance.
Who Still Allows Cosigners
Federal law requires anyone under 21 applying for a credit card to either show independent ability to repay or provide a cosigner who is at least 21 and financially able to cover the account.1Office of the Law Revision Counsel. 15 USC 1637(c) – Disclosure in Credit and Charge Card Applications and Solicitations The law didn’t ban cosigning, but the compliance burden pushed major issuers out of the practice. American Express, Chase, and Citibank all moved to an authorized-user model, where a second person gets a card but carries no legal obligation for the balance.
Realistic options now sit with credit unions and regional banks that still underwrite joint applications. U.S. Bank has been reported to accept cosigners in some situations. Expect to call around rather than apply online, because the institutions that still do this rarely advertise it.
Cosigner Versus Authorized User
These two arrangements get confused constantly, and the difference is the entire point of this decision.
A cosigner is legally responsible for the full balance if the primary cardholder doesn’t pay. The cosigner usually doesn’t receive their own card and may have no way to monitor the account. It appears on the cosigner’s credit report, and any missed payment damages their score.
An authorized user gets a card in their name attached to someone else’s account. They can make purchases, and the account history can appear on their credit report, which helps build credit. But they have no legal obligation to pay. The primary cardholder can remove them at any time.
For a parent trying to help a child build credit, the authorized-user route reaches the same goal without the legal exposure. Cosigning only makes sense when the primary applicant genuinely cannot get approved any other way and needs an independent account in their own name.
What a Cosigner Actually Qualifies For
Lenders are looking for someone strong enough to carry the entire credit line alone. Thresholds vary, but the benchmarks are consistent:
- A credit score in the good-to-excellent range, generally 670 or higher.
- A debt-to-income ratio under 50 percent, including payments on the new account.
- Verifiable, stable income.
- Age 21 or older if the primary applicant is under 21; a legal adult otherwise, though most lenders prefer 21 and up regardless.1Office of the Law Revision Counsel. 15 USC 1637(c) – Disclosure in Credit and Charge Card Applications and Solicitations
What You’re Agreeing To as a Cosigner
This is where most people underestimate the arrangement. Cosigning creates joint and several liability. The lender can pursue the cosigner for the entire outstanding balance without first trying to collect from the primary cardholder. The creditor doesn’t have to show that the primary borrower refused to pay or that collection against them failed. It can come straight to the cosigner for 100 percent of the debt.
The account also lands on the cosigner’s credit report like any other debt. Issuers are required to report accurate account information to the credit bureaus, and that reporting flows to both parties on the account.2Office of the Law Revision Counsel. 15 USC 1681s-2 – Responsibilities of Furnishers of Information to Consumer Reporting Agencies Late payments, high utilization, or a charged-off balance will damage the cosigner’s score and raise their debt-to-income ratio, which can block them from qualifying for a mortgage, car loan, or new credit card of their own.
The contract stays in effect until the balance is paid in full or the issuer agrees to release the cosigner. Credit card issuers rarely include a release clause, so the cosigner is typically tied to the account for its full life. You are not helping temporarily. You are on the hook until every dollar is paid.
Liability Without Visibility
Here is the part that catches cosigners off guard. Despite being fully liable, you often have very little control over the account. Most cosigners don’t receive their own card. Many issuers don’t give cosigners direct online access or send them monthly statements. You may have no way to see what the primary cardholder is charging, no ability to set a spending limit, and no authority to freeze or close the account on your own.
The primary cardholder controls the spending. The cosigner absorbs the risk. That imbalance is baked into the arrangement, and it’s the main reason financial advisors routinely steer people away from cosigning credit cards whenever an alternative exists. If you do cosign, work out an informal agreement with the primary cardholder to share login credentials or forward statements, so you learn about a problem before it shows up on your credit report.
If the Primary Cardholder Stops Paying or Files Bankruptcy
Default on the account becomes the cosigner’s problem immediately. The creditor can bill the cosigner for the full balance, report missed payments to the bureaus, and eventually refer the account to collections against the cosigner directly.
Bankruptcy by the primary cardholder offers the cosigner almost no protection. A Chapter 7 discharge only eliminates the primary borrower’s obligation; it does not touch the cosigner’s liability.3Office of the Law Revision Counsel. 11 USC 524 – Effect of Discharge The creditor turns to the cosigner for the full remaining balance.
Chapter 13 offers a temporary shield. While the primary borrower’s repayment plan is active, an automatic stay prevents creditors from collecting consumer debts from cosigners.4Office of the Law Revision Counsel. 11 USC 1301 – Stay of Action Against Codebtor That protection ends if the case is dismissed, converted to Chapter 7, or if the repayment plan doesn’t include the cosigned debt. Once the stay lifts, the cosigner is fully exposed.
Getting Released From a Cosigned Card
Getting off a cosigned credit card is harder than getting on one. The most reliable path is for the primary cardholder to pay the balance to zero and then close the account entirely. If the account stays open with a zero balance, the primary cardholder can run up new charges that you remain liable for.
A few other paths exist, none guaranteed:
- A formal release request, if the agreement allows one. Most credit card contracts don’t include this, and where it exists the lender usually requires the primary cardholder to qualify independently before releasing the cosigner.
- A balance transfer or refinance. If the primary cardholder’s credit has improved, they may qualify for a new card alone, transfer the balance, and close the cosigned account.
- A negotiated release during hardship. Issuers occasionally agree to release a cosigner as part of a settlement, usually only when default is the alternative.
Lower-Risk Alternatives
Before anyone signs a cosigned application, check whether a less risky arrangement reaches the same goal.
Authorized user. The primary cardholder adds the other person to their existing account. The authorized user can build credit history from the account without either party taking on the liability of a cosigned debt. The primary cardholder can set spending limits on some cards and remove the authorized user at will.
Secured credit card. The applicant puts down a refundable deposit, often as little as $200, that serves as collateral and typically sets the credit limit. Secured cards are designed for people with limited or damaged credit, approval rates are high, and many issuers offer a path to an unsecured card after several months of on-time payments. No cosigner required.
Credit-builder loan. These small loans, usually from credit unions, deposit the borrowed amount into a locked savings account. The borrower makes fixed monthly payments reported to the credit bureaus, and the funds release when the loan is paid off. A slower route to credit, but it carries no risk to anyone else.
Cosigning a credit card is one of the few financial decisions where the person taking on the most risk gets the least benefit. If you’re considering it, make sure the alternatives have genuinely been ruled out first.
