Residential mortgage holders with IBRC are still waiting for their mortgages to be taken from their accounts after the Special Liquidator took over at the beginning of this month.
IBRC was formerly Anglo Irish Bank and Irish Nationwide Building Society.
The mortgage holders' IBRC bank sort codes were suspended when the liquidator, KPMG, took over management of the loans.
This means it has not been possible to transfer monthly mortgage payments out of accounts and into those of the KPMG Special Liquidator.
The money is still owed and the mortgage holders are waiting for details of what to do to make their monthly payments.
IBRC's residential mortgage book is worth €1.8 billion.
