Before You Co-Sign: Checklist

Question If the Answer Is No…
Can I afford to pay this loan if they can’t? Don’t co-sign
Do I trust this person’s financial habits? Don’t co-sign
Am I okay losing this relationship if things go wrong? Don’t co-sign
Have I seen their budget and financial situation? Ask before signing
Is there a co-signer release clause? Negotiate one or reconsider
Will this affect my own borrowing plans? Calculate the impact first
Have I read the full loan agreement? Read every page before signing

How to Protect Yourself If You Co-Sign

Protection How
Get co-signer release clause in writing Some lenders release after 12-24 months of on-time payments
Set up payment alerts Ask lender to notify you of any missed payments
Monitor your credit report Check monthly for the co-signed account
Keep copies of everything Loan agreement, payment history, communications
Written agreement with borrower Not legally binding against lender, but clarifies expectations
Cap the amount Co-sign the minimum needed, not more
Set a time limit Agree that borrower refinances within a set period

Alternatives to Co-Signing

Alternative Details
Help with a down payment Gift money to reduce the loan amount
Secured credit card Borrower deposits cash as collateral
Credit-builder loan Small loan designed to build credit (no co-signer needed)
Become an authorized user Add them to your credit card (you control the account)
Delayed purchase Wait until they’ve built enough credit
Credit union Often more flexible lending criteria
Joint account vs co-signing Different legal structure, consider carefully

How to Remove Yourself as a Co-Signer

Method Likelihood of Success
Borrower refinances on their own Best option — completely removes you
Co-signer release clause If the lender offers it (after on-time payments)
Pay off the loan Eliminates the obligation
Negotiate with lender Difficult, but worth trying
Sell the asset If it’s a car loan, selling the car can pay off the loan
Bankruptcy (yours) May discharge obligation, but destroys your credit

What does NOT remove you:

Action Removes You?
Verbal agreement with borrower No
Divorce decree No (lender is not bound by divorce agreements)
Borrower says they’ll take over No (only lender can release you)
Closing your other accounts No
Moving provinces No
