You can file bankruptcy. If the debt is discharged in the chapter 7, you would need to bring a motion to avoid the judgment lien during your bankruptcy case. This is allowed if the judgment lien impairs your homestead exemption.
So, let's say your house is worth 200,000. After subtracting the mortgage balance, if the amount is less than the allowed homestead (see below) then the motion would be granted. If there is still equity
after the exemption is subtracted, then the lien can stay on that portion of the equity, and the court may allow a deduction of the total lien.
