You filed bankruptcy and the lender is still wanting you to make payments. If you filed a Chapter 7 bankruptcy, you are no longer liable if you fail to make payments on your mortgage payment.
This does not mean that you get to keep the house and not pay the mortgage lien holder. Even though you cannot be sued personally for a failure to pay the mortgage payments as they come due, the lender can still foreclose on the property. There are two types of liability that are a part of the duty to make payments on the mortgage. A lender can usually use both types of liability one called In personam liability and the other called In Rem liability.
After filing a Chapter 7 bankruptcy and obtaining your discharge, a debtor is only liable to a mortgage creditor for In Rem liability. The creditor still has the right to sell the property to satisfy the indebtedness owed. This is why a lender can foreclose on the property either before or after a Chapter 7 Bankruptcy discharge.
In personam liability gives the lender the right to look to a person for payment if the sale of the property did not pay the full amount owed to the lender. A Chapter 7 bankruptcy only discharges or eliminates the In personam liability.
So no, after you get your discharge in a Chapter 7 bankruptcy, you do not have to make the mortgage payments. If you do not make the payments, however, the lender can foreclose on the property.
