It follows a case won by a Donegal couple who took on the State's largest moneylender through the financial services ombudsman.
They had loans from Provident Personal Credit, but were illegally offered new loans before they paid off the old ones.
The couple complained to the ombudsman, won their case, and got compensation.
Personal Finance Editor with the Irish Independent Charlie Weston explains who might be in line to have their debt wiped-out.
