When parents cosign a private student loan, they’re usually told that once the borrower makes a set number of on-time payments, the cosigner can apply to be released from the loan.

On paper, it sounds like an exit plan. In practice, federal regulators and consumer advocates have flagged cosigner release as one of the most opaque corners of the private student loan market — and the data suggests very few people who try actually get out.

Roughly 90% of cosigner release applications were denied, according to a Consumer Financial Protection Bureau report on industry practices. The CFPB also found that borrowers and cosigners had little visibility into what specifically would qualify them, and were often left without a clear explanation when they were turned down.

What Is Cosigner Release?

A cosigner is a second person (often a parent) who promises to repay a private student loan if the primary borrower can’t. The loan sits on both parties’ credit reports and counts against both of their debt-to-income ratios. That can make it harder for the cosigner to qualify for a mortgage, a car loan, or even an apartment lease.

Cosigner release was designed to give parents an off-ramp after their child got on their feet financially after college. After the primary borrower makes a set number of consecutive on-time payments (typically 12 to 48 months, depending on the lender) the borrower can apply to take the loan into their name alone. If approved, the cosigner is removed from the obligation entirely. The credit report no longer shows the balance, and the loan no longer counts against their borrowing capacity.

For the borrower, qualifying for release usually requires more than just a payment history. Lenders want to see proof of income sufficient to handle the loan on its own, plus a credit check that meets the lender’s underwriting standards.

90% Rejection Rate

The CFPB’s findings gives families a window into how cosigner release actually works. Based on its review of complaints and industry data, the bureau reported that 90% of borrowers who applied for cosigner release were denied. The agency cited two recurring problems.

The first was disclosure. Borrowers and cosigners often didn’t know what specific criteria they had to meet, and even when they were denied, lenders frequently provided no actionable explanation.

The second was process. Some servicers required borrowers to submit applications during narrow windows, restart payment counters after any forbearance or modified repayment schedule, or supply documentation that wasn’t disclosed up front.

The CFPB also flagged auto-default clauses in many private student loan contracts that put loans into default automatically if a cosigner died or filed bankruptcy — even when the borrower had been paying on time. Some of those practices have since been curtailed, but the underlying release rate problem has not meaningfully shifted in the years since.

How Private Student Loan Lenders Compare

Each lender sets its own threshold, and the published rules vary widely:

• Ascent Student Loans: Borrowers can request release after 12 consecutive on-time principal-and-interest payments.
• College Ave Student Loans: Release can be requested after the borrower has completed half the original payment schedule.
• Sallie Mae: Release is available after 12 on-time principal-and-interest payments, with no 30-day-plus delinquencies in the prior 12 months, no hardship forbearance or modified repayment in that window, and a credit review showing no bankruptcy, foreclosure, or 90-day delinquencies in the prior 24 months.
• Earnest Student Loans: Does not offer cosigner release on its in-school loans. Borrowers who want a cosigner removed have to refinance.

Beyond the published rules, most lenders layers in two phrases that do most of the work in a denial: “sufficient income” and “satisfactory credit.” Neither is defined in numeric terms. A borrower making $55,000 a year with a 720 credit score might qualify at one lender and be denied at another with identical loan terms.

Student Loan Refinancing Is The Real Pathway Forward

Many lenders quietly prefer that borrowers refinance their student loans rather than pursue release, and the math often works out in the borrower’s favor anyway.

A student loan refinance means taking out a new student loan in the student’s name only to pay off the existing loan that has a cosigner attached. If the student qualifies on their own credit and income and the refinance loan is completed, the parent is removed from the obligation the day the old loan is paid off.

Refinancing can also lower the interest rate if the borrower’s credit has improved since the original loan was taken out. Lenders that offer student loan refinancing (including Earnest, SoFi, ELFI, and Splash Financial) underwrite to the new borrower’s standalone profile, which is the same financial test most cosigner release programs apply, just packaged as a new loan.

What This Means For Families

For parents who cosigned during their child’s college years, the practical impact is significant. The loan stays on the parent’s credit report for years after graduation, potentially impacting future life choices.

Even when the primary borrower is paying on time and never misses, the balance still counts against the cosigner’s debt-to-income ratio when underwriters evaluate new credit. A $40,000 student loan balance can shave tens of thousands of dollars off what a parent qualifies to borrow on a mortgage.

Cosigners also carry the credit risk. If the borrower hits a rough patch and goes 30 or 60 days late, that mark hits both credit reports and (under most release programs) also resets the on-time payment clock the borrower would need to qualify for release later.
