I just realized my mortgage lender used $5,100 of my escrow money to pay someone else’s property taxes twice — 20 years ago. I’m furious. What can I do now?

Hypothetically, what could you do to rectify the situation and hopefully get your money back?

Understand your rights

You have rights as a borrower, and a lender isn't allowed to use the money in your escrow account for anything other than what was agreed upon.

According to the Federal Reserve, the Real Estate Settlement Procedures Act (RESPA) requires lenders to provide an itemized list of what will be paid with the funds and where the money goes once it’s paid out by the servicer.

If you find out that your mortgage company used the funds in your escrow account incorrectly, it’s a good idea to contact your local tax authority and see what its records show. Getting your paperwork in order is your first priority, as you’ll need documentation to prove your situation.

Then, contact your mortgage lender to find out what happened on its end. The New York State Department of Financial Services says to first file a formal complaint in writing.

In most cases, the lender will respond within 20 business days and resolve the issue within 60 business days. By this time, it’ll either correct the issue — in this case, return the $5,100 back to your account — or provide a statement that covers why it denied your complaint or request.

When to escalate

If you don’t get the response you hoped for, you can escalate the issue and submit a complaint online with the Consumer Financial Protection Bureau (CFPB).

Like the complaint you submitted to your lender, you’ll need to provide as many details as possible. The CFPB asks that you be clear and concise and include any important dates and amounts the mortgage lender took from you. Don’t forget to provide your contact details and the name of your mortgage lender.
