Can I be foreclosed without going through courts?

I had 2 loans to purchase my home in 2005. As a single mother, i was shocked to get a house. But God has been good to me. Anyway, i paid for the 10 years to a second loan and stopped. But today i got a notice of forclosure for 35,000 but I have been paying the main mortgage. Im current with that loan, i just thought my other loan was finished. I was paying even through bankruptcy. I paid 19,500 through bankruptcy and 16500 through my own payments before bankruptcy. Can they sale my house even though im good on my big loan? Can they do it without filing anything through the courts? I mean this isn't even on my credit. This is the strangest thing.
