Receivers have now taken possession of the Gorse Hill property in Dublin, which has been the subject of a protracted legal battle.
Solicitor Brian O'Donnell and his wife Mary Patricia, who owe Bank of Ireland over €70m, left the property this morning ahead of a noon deadline set by the courts.
However, Mr O'Donnell then headed to the Bank of Ireland AGM - where he presented CEO Richie Boucher with the keys to the €7m Killiney mansion.
He also reiterated his intention to take his case to the European courts.
Despite the arrival of the receivers at the house, the Land League stated that it was taking possession of the property for an Isle Of Man registered company - Vico Limited - which is controlled by the O'Donnell's adult children.
Blake O'Donnell - who is the secretary of Vico Limited - also attended the Bank of Ireland AGM, where he voiced his anger with the bank's management.
Jerry Beades, from the Land League, says he has been instructed to send the keys of the property to the Isle of Man.
He says the receiver appointed by the bank has been notified of developments.
