MARS Rule (Regulation O)

by | May 15, 2026

The Mortgage Assistance Relief Services (“MARS”) Rule, also known as Regulation O, is a federal consumer protection regulation issued by the Federal Trade Commission (“FTC”) to address deceptive and abusive practices involving mortgage relief and foreclosure rescue services. The rule applies to individuals and companies that offer services to assist consumers with obtaining loan modifications, preventing foreclosure, negotiating with lenders, or otherwise providing mortgage relief assistance in exchange for compensation. Regulation O prohibits false or misleading claims about the likelihood of obtaining mortgage relief, bans the collection of advance fees before a written agreement is reached between the consumer and the lender, and requires specific disclosures informing consumers that they may stop doing business with the provider at any time and that the provider is not affiliated with the government or the borrower’s lender unless such affiliation actually exists.

For Mortgage Loan Originators (“MLOs”), the MARS Rule is significant because mortgage professionals involved in loan modification or foreclosure assistance activities must ensure that all advertising, communications, and fee practices comply with federal consumer protection requirements. MLOs must avoid making guarantees or misleading representations regarding loan modification outcomes and must provide required disclosures clearly and accurately. Even when working on legitimate loss mitigation or mortgage assistance programs, mortgage professionals are subject to strict standards intended to protect financially distressed consumers from fraud and unfair practices. Violations of the MARS Rule can result in regulatory enforcement actions, civil penalties, restitution obligations, and reputational damage, making compliance an important responsibility for mortgage-related service providers.
