Overview

A loan modification rewrites repayment terms—interest rate, schedule, or principal—to help the primary borrower. In nearly all routine modifications the cosigner’s obligation stays intact unless the lender explicitly agrees to release the cosigner in writing. In my practice I’ve seen many cosigners assume a modification ends their liability; that misconception causes preventable credit damage and collection risk.

Key outcomes for cosigners

  • Liability usually remains: A modification modifies terms but does not erase the original promise to repay unless the lender issues a written release or a new contract (novation) is signed.
  • Credit impact: Late or missed payments after modification still appear on the cosigner’s credit report and can lower their score (see CFPB guidance).
  • Collection risk: The lender may pursue the cosigner for missed payments or full balance if the primary borrower defaults.

Why liability usually stays

Loan contracts make the cosigner a secondary obligor. A loan modification is typically an amendment to the existing contract, not a new agreement replacing it. Because the original obligation remains enforceable unless replaced or released, lenders commonly retain the right to collect from any party who signed the original note.

Options to remove or reduce cosigner risk

  • Request a cosigner release: Some lenders offer a formal release after the borrower meets credit and payment criteria. Get this in writing and confirm the loan number and effective date. See FinHelp’s guide on Cosigner Release Requests: Timing and Documentation.
  • Refinance the loan: If the borrower qualifies on their own, refinancing into a new loan removes the cosigner because the old note is paid off. Learn how refinancing interacts with cosigners in Refinancing With a Cosigner Still on the Note.
  • Novation or re-underwriting: Rare but possible—lender drafts a new agreement substituting parties and releasing the cosigner; this requires lender approval and new signatures.
  • Pay off the loan: Satisfying the balance removes future risk.

Practical steps for cosigners (do these now)

  1. Read the modification agreement carefully and compare it to the original promissory note.
  2. Ask the servicer in writing whether the modification includes or triggers a cosigner release. Keep written responses.
  3. Request a formal cosigner release or discuss refinancing options. See our related explainer on How to Request a Cosigner Release.
  4. Monitor your credit reports for changes and any new delinquencies (annualcreditreport.com and CFPB resources recommended).
  5. Consider negotiating safeguards: autopay from the borrower’s account, hardship forbearance terms that limit reporting, or a temporary guarantor arrangement.

Real-world example

A borrower receives a modification lowering monthly payments; the lender does not issue a release. Months later the borrower misses payments. The cosigner—still on the note—sees collection calls and a drop in credit score. Had the cosigner secured a written release or insisted on refinancing, this harm could have been avoided.

Common mistakes to avoid

  • Assuming a modification equals release: Always get a release in writing.
  • Failing to document communications: Verbal statements from servicers are not enforceable—save emails and letters.
  • Ignoring credit monitoring: Cosigners often learn of problems only after missed payments appear on their credit report.

When a cosigner might be released automatically

Automatic release is uncommon. Some private lenders embed release triggers (e.g., X on-time payments, borrower credit score threshold) but they must be documented in the loan or modification. Don’t rely on unstated or informal promises.

Where to get help and authoritative sources

  • Consumer Financial Protection Bureau (CFPB): consumerfinance.gov — advises cosigners and borrowers on rights and servicer communications.
  • National Foundation for Credit Counseling (NFCC): credit.org — for budgeting, debt counseling and negotiation help.

Professional note

In my 15 years advising borrowers and cosigners, the most effective protection is written documentation: a clear cosigner-release clause, or a refinance that removes the cosigner from the note. Lenders can and do make exceptions, but they must be formalized.
