The Irish Bank Resolution Corporation, formerly known as Anglo Irish Bank, is to challenge Seán Quinn's bankruptcy.
Mr Quinn applied to have himself made bankrupt in the High Court in Belfast on Friday.
In his petition to the court in Belfast - which was obtained by lawyers for IBRC this morning - he said he was doing this as the registered office and place of business of the Quinn Group companies was Derrylin in Co Fermanagh.
He also said he was domiciled for tax purposes in Northern Ireland and his tax affairs were conducted in the UK.
Senior Counsel Paul Gallagher for IBRC said it had evidence which contradicted Mr Quinn's claim that his centre of main interest was in Northern Ireland.
IBRC claims that Mr Quinn consistently indicated that his home address was Ballyconnell in Co Cavan in the annual returns of 95 companies of which he was or is a director.
He does not hold any directorships with active UK companies the court was told.
The bank intends to bring an application by the end of this week or early next week to have the bankruptcy annulled.
Anglo is seeking judgment orders against Mr Quinn of more than €2bn.
The Commercial Court today approved an application by IBRC to transfer the case into the fast track division.
Mr Justice Peter Kelly granted a short adjournment on the application for judgment until next Monday to allow the court official in Northern Ireland, who will be responsible for Mr Quinn's bankruptcy, to indicate his position to the court.
