Is any paper needed to wipe out junior liens after auction sale?

Does an auction sale of the 1st DT automatically wipe out all junior liens? or?

Is there any formal paper work need to be recorded in the County office to cancel the junior liens?

? Yes - All juniors are wiped out. ?

? ?No - You don’t need to record any “paper”

? ?The only exception is that an IRS lien doesn’t become “wiped out” for 120 days. ?
