The CARES act allows people for the next year to be able to modify their plans from 3- or 5-year plans to up to a 7-year plan. You may also be able to reduce your payment plans due to changed circumstances. This only applies to plans that had already been confirmed prior to the pandemic.
It may also be possible for the trustee or a creditor to move for modification of a plan
In the short term you may be able to suspend up to 3 payments if you can establish a loss of income or documented hardship. The Trustee drafts a stipulation if the trustee agrees to the hardship. Payments would increase moving forward to make up for the missed payments.
You may request the deferment of 3 months and then move for the 7-year plan option if circumstances have not improved in the 3 months.
