Hi , I filed chapter 7 now the bank won't take my mortgage payment, they told me pay it through the bankruptcy courts. What do I do?

Did you include the house in the bankruptcy filing ?

Have you re-affirmed the debts for property you are keeping ( house, cars)

Unless you did something wrong in the filing, you merely keep sending the lender your monthly payment.

If you are including the house in the bankruptcy, the court will sell the house to help pay the debts

Ask your BK lawyer. Many times they do not give information until you ask.
