The official in charge of the Sean Dunne bankruptcy case in the US state Connecticut has decided to join with Ulster Bank in trying to get the case partially heard in Ireland.
Sean Dunne has been living in the US for a number of years.
He applied for bankruptcy in Connecticut, saying he had almost $1bn (€769m) in debts and very few assets.
Ulster Bank, which is owed hundreds of millions by Mr Dunne, applied to the Connecticut court to allow it to proceed with a bankruptcy case in Ireland.
It says Mr Dunne went to extreme lengths to avoid the bank serving papers on him in the US.
Richard Coan, the bankruptcy trustee who oversees the case, has said he partially agrees with Ulster Bank.
Mr Coan says all of Mr Dunne's secured creditors are Irish.
As such, Irish law will govern much of the case.
Mr Coan wants the court in America to negotiate a protocol with the Irish courts so that the case can proceed in the most efficient manner.
