The National Asset Management Agency has obtained an order in the High Court in London to prevent developer Ray Grehan disposing of any assets worldwide.
The order was granted to National Asset Loan Management, one of NAMA's operating divisions.
If Mr Grehan sells any of his worldwide property portfolio, he will be in breach of a UK High Court order.
NAMA has recently obtained an injunction in Canada to prevent the sale by Mr Grehan of a luxury apartment in Toronto, and is involved in court action against Mr Grehan in New York to prevent the sale of an apartment in the Rockefeller Center.
There is ongoing litigation in the UK courts connected to other property assets belonging to Mr Grehan.
Separately, NAMA has tendered for a panel of credit investigators to check on the assets of developers who owe money to the agency.
NAMA has used credit investigators since its inception, but is now establishing a panel of advisors it can call on.
